Opportunities

Defer offscreen images
Time to Interactive can be slowed down by resources on the page. Askci.com should consider lazy-loading offscreen and hidden images.
Minify CSS
Cascading Style Sheets (CSS) files can contribute to network payload sizes. Askci.com should consider minifying CSS files.
Minify JavaScript — Potential savings of 19 KiB
JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Askci.com should consider minifying JS files.
URL Transfer Size (Bytes) Potential Savings (Bytes)

3313
Remove unused CSS
Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. Askci.com should consider removing dead rules from style sheets and deferring the loading of CSS not used for above-the-fold content.
Remove unused JavaScript
It is advised to remove unused JavaScript in order to reduce bytes consumed by network activity.
Enable text compression
Text-based resources should be served with compression, such as gzip, deflate or brotli.
Preconnect to required origins
Resource hints, such as 'preconnect' or 'dns-prefetch', may assist in establishing early connections to important third-party origins.
Avoid multiple page redirects — Potential savings of 190 ms
Redirects can cause additional delays before the page can begin loading. Askci.com should avoid multiple or unnecessary page redirects.
URL Time Spent (Ms)
http://askci.com/
190
https://www.askci.com/
0
Preload key requests
Key requests can be preloaded by using '<link rel=preload>'. Askci.com should consider using '<link rel=preload>' to prioritize fetching resources that are currently requested later in page load.
Use video formats for animated content
Large GIFs are inefficient for delivering animated content. It is recommended to use MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF.
Remove duplicate modules in JavaScript bundles
Ensure that no duplicate JavaScript modules from bundles exist to reduce bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers
Polyfills and transforms enable legacy browsers to use new JavaScript features. For bundled JavaScript it is recommended to adopt a modern script deployment strategy using module/nomodule feature detection. This will reduce the amount of code shipped to modern browsers.

Diagnostics

Avoid chaining critical requests — 16 chains found
Below is a list of Critical Request Chains, which shows which resources are loaded with a high priority. Askci.com should consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
User Timing marks and measures
Make use of the User Timing API to measure an app's real-world performance during key user experiences.
JavaScript execution time — 0.1 s
JavaScript (JS) execution time can be lowered by reducing the time required for parsing, compiling and executing JS. Delivering smaller JS payloads may help with this.

Accessibility

Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of askci.com. This includes details about various page attributes that can be optimized.

Navigation

`[accesskey]` values are unique
Access keys assist users with focusing on different parts of the page. Each access key should be unique for proper navigation.
The page contains a heading, skip link, or landmark region
It is advised to provide ways to bypass repetitive content, allowing users to navigate the page efficiently.
`[id]` attributes on active, focusable elements are unique
Ensure all focusable elements have a unique id value to allow them to be visible to users of assistive technologies, like a screen reader.
Heading elements appear in a sequentially-descending order
Properly order all headers and do not skip heading levels to better the navigation and readability for users of assistive technologies, like a screen reader.
No element has a `[tabindex]` value greater than 0
Although technically valid, a tabindex value greater than 0 often creates frustrating experiences for users who rely on assistive technologies.

ARIA

`[aria-*]` attributes match their roles
Avoid mismatching 'aria-*' attributes and their 'role' value, as it invalidates the attribute.
`[aria-hidden="true"]` is not present on the document `<body>`
If aria-hidden=true is set on the document body, assistive technologies, like a screen reader will work inconsistently.
`[aria-hidden="true"]` elements do not contain focusable descendents
Interactive elements within an aria-hidden=true element are unavailable to users of assistive technologies, like a screen reader.
ARIA input fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when an input field does not have an accessible name specified.
`[role]`s have all required `[aria-*]` attributes
Some ARIA roles have required 'aria-*' attributes, which provide essential information about state and functionality.
Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children.
Some ARIA parent roles cannot perform their intended functions if specific child roles are not used.
`[role]`s are contained by their required parent element
Some ARIA child roles cannot perform their intended functions if specific parent roles are not used.
`[role]` values are valid
All ARIA roles require valid values to perform their intended functions.
ARIA toggle fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when a toggle field does not have an accessible name specified.
`[aria-*]` attributes have valid values
ARIA attributes cannot be interpreted with invalid values when used by screen readers and other assistive technologies.
`[aria-*]` attributes are valid and not misspelled
ARIA attributes cannot be interpreted with invalid names when used by screen readers and other assistive technologies.
ARIA IDs are unique
Ensure all ARIA ID values are unique to prevent elements from being overlooked by assistive technologies, like a screen reader.

Names and labels

Buttons have an accessible name
Buttons become unusable as they are announced simply as "button" when the button does not have an accessible name, when used by screen readers and other assistive technologies.
Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
No form fields have multiple labels
Having multiple labels for form fields can be confusing to assistive technologies, like a screen reader.
`<frame>` or `<iframe>` elements have a title
Screen reader users and other assistive technology users rely on frame titles to describe the contents of frames.
`<input type="image">` elements have `[alt]` text
Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.
`<object>` elements have `[alt]` text
It is advised that alt text is used on '<object>' elements in order to provide meaning to screen reader and other assistive technology users, as these technologies are unable to translate non-text content.

Tables and lists

`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements.
Screen readers and other assistive technologies may produce poor and inaccurate output when definition lists are not properly marked up.
Definition list items are wrapped in `<dl>` elements
In order for screen readers and other assistive technologies to properly announce definition list items ('<dt>' and '<dd>'), they must be wrapped in parent a '<dl>' element.
Presentational `<table>` elements avoid using `<th>`, `<caption>` or the `[summary]` attribute.
It is advised to not include data elements in tables which are used for layout purposes, as it may create confusion for screen reader and other assistive technology users.
Cells in a `<table>` element that use the `[headers]` attribute refer to table cells within the same table.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that '<td>' cells using the headers attribute only refer to other cells in the same table, to improve screen reader user experience.
`<th>` elements and elements with `[role="columnheader"/"rowheader"]` have data cells they describe.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that table headers refer to some set of cells, to improve screen reader user experience.

Internationalization and localization

`<html>` element has a `[lang]` attribute
It is advised to provide a lang attribute so that screen readers and other assistive technologies are guaranteed to announce the page's text correctly. When not provided, the user's default language setting will be used which may cause inaccuracies.
`<html>` element has a valid value for its `[lang]` attribute
Specify a valid BCP 47 language in order to help screen readers and other assistive technologies announce text properly.
`[lang]` attributes have a valid value
Specify a valid BCP 47 language on elements in order to help screen readers and other assistive technologies announce text properly.

Best practices

The document does not use `<meta http-equiv="refresh">`
Pages that refresh automatically cause a poor user experience as focus is directed back to the top of the page unexpectedly.
`[user-scalable="no"]` is not used in the `<meta name="viewport">` element and the `[maximum-scale]` attribute is not less than 5.
For users with low vision who rely on screen magnification, ensure that zooming is not disabled.

Audio and video

`<video>` elements contain a `<track>` element with `[kind="captions"]`
Askci.com may provide assistance to deaf or hearing-impaired users with captions on videos.
`<video>` elements contain a `<track>` element with `[kind="description"]`
Askci.com may provide relevant information that dialogue cannot, by using audio descriptions.

Form elements do not have associated labels
Screen readers and other assistive technologies rely on labels to properly announce form controls.
Failing Elements
Links do not have a discernible name
In order to improve the navigation for screen reader and other assistive technology users, use link text that is unique, focusable and discernible.

Tables and lists

Manual Checks

The page has a logical tab order
The visual layout should be logical in its tab order and users cannot focus elements that are offscreen.
Interactive controls are keyboard focusable
Ensure that custom interactive controls are keyboard focusable and that a focus indicator is displayed.
Interactive elements indicate their purpose and state
Ensure that interactive elements (such as links and buttons) are distinguishable from non-interactive elements and that they indicate their state.
The user's focus is directed to new content added to the page
When new content (such as a dialogue) is added to the page, the user's focus should be directed to it.
User focus is not accidentally trapped in a region
Avoid focus being accidentally trapped when a user tabs in and out of controls or regions on page.
Custom controls have associated labels
Ensure that custom interactive controls have associated labels, which are provided by aria-label and aria-labelledby attributes.
Custom controls have ARIA roles
Ensure that all custom interactive controls have appropriate ARIA roles.
Visual order on the page follows DOM order
Ensure that the DOM order matches with the page's visual order, in order to improve navigation for screen readers and other assistive technologies.
Offscreen content is hidden from assistive technology
Ensure that offscreen content is hidden through the use of "display:none" styling or the aria-hidden attribute.
HTML5 landmark elements are used to improve navigation
Elements such as <main> and <nav> are recommended as they are used by screen readers and other assistive technologies to improve keyboard navigation.

SEO

Indicates how well the page is optimized for ranking in search engines and highlights Search Engine Optimization (SEO) opportunities for askci.com. This includes optimizations such as providing meta data.

Content Best Practices

Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
Document has a meta description
Meta descriptions may be used by search engines when displaying a link to the page and should concisely summarize the page's content.
Links have descriptive text
Make use of descriptive link text to assist search engines in understanding the content.
Document has a valid `hreflang`
Search engines can be instructed to list specific versions of a page for a given language or region through the use of hreflang links.
Document has a valid `rel=canonical`
Search engines can be suggested which URL should be shown in search results through the use of canonical links.
Document avoids plugins
The content of plugins cannot be indexed by search engines and many devices either restrict or do not support them.

Crawling and Indexing

Page has successful HTTP status code
Avoid pages with unsuccessful HTTP status codes as they may not be indexed by search engines.
Page isn’t blocked from indexing
Pages that cannot be crawled by search engines cannot be indexed or included in their search results. Ensure that search engines have permission to crawl all pages that should be indexed.
robots.txt is valid
Malformed robots.txt files prevent crawlers from understanding how a site wants to be crawled or indexed, which can be devastating to SEO.

Mobile Friendly

Document uses legible font sizes
Font sizes of 12px or less are too small to most mobile users without user gestures and further action. Aim for more than 60% of page text to use font sizes greater than 12px.
Tap targets are sized appropriately
Interactive elements (such as buttons and links) should be appropriately spaced, sized and easy enough to select or tap with regard to their surrounding elements.

Mobile Friendly

Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
It is advised to use a '<meta name="viewport">' tag for the optimization of askci.com on mobile screens.

Crawling and Indexing

Links are not crawlable
Ensure that the 'href' attribute of anchor elements links to the appropriate destination. This allows for more pages of the site to be discovered by search engines.

Content Best Practices

Image elements do not have `[alt]` attributes
Provide short and descriptive alternative text where possible on informative elements.

Consider using a service worker for Progressive Web Apps to ensure greater reliability for the user, in the case of poor network conditions.

Installable

Does not use HTTPS — 1 insecure request found
Ensure that all pages are protected with HTTPS (including those that do not handle sensitive data) as HTTPS prevents tampering and passive listening on communications between the app and its users. Additionally, HTTPS is a prerequisite for HTTP/2 and many new web platform APIs.
Insecure URL
http://askci.com/
Does not register a service worker that controls page and `start_url`
A service worker is used to provide Progressive Web Apps the use of features such as working offline, the ability for the app to be added to the homescreen as well as push notifications.
Web app manifest does not meet the installability requirements
User engagement may be increased by leveraging the browsers ability to proactively prompt users to add the app to their homescreen.
View Data

PWA Optimized

Is not configured for a custom splash screen
Themed splash screens ensure a high-quality user experience at launch for app users.
View Data
Does not set a theme color for the address bar.
A theme may be applied to the browser address bar, which ideally can be made to match the site.
View Data
Does not have a `<meta name="viewport">` tag with `width` or `initial-scale`
It is advised to use a '<meta name="viewport">' tag for the optimization of askci.com on mobile screens.
Does not provide a valid `apple-touch-icon`
iOS users of Progressive Web Apps will benefit from an apple touch icon, which can be defined with 'apple-touch-icon', which must point to a non-transparent 192px (or 180px) square PNG.
Manifest doesn't have a maskable icon
Maskable icons are great to ensure that images fill the entire shape when installing the app on a device.

Manual Checks

Site works cross-browser
Ensure that the Progressive Web App works correctly across every major browser.
Page transitions don't feel like they block on the network
Users perceive apps with responsive, snappy transitions as higher peforming and ensures a great user experience, even on a slow network.
Each page has a URL
Ensure that all pages are deep linkable via URL. They should also be unique for the purpose of shareability on social media.

Minify CSS
Cascading Style Sheets (CSS) files can contribute to network payload sizes. Askci.com should consider minifying CSS files.
Minify JavaScript — Potential savings of 3 KiB
JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Askci.com should consider minifying JS files.

Remove unused CSS
Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. Askci.com should consider removing dead rules from style sheets and deferring the loading of CSS not used for above-the-fold content.
Efficiently encode images
Unoptimized images can consume more cellular data than what is necessary.
Enable text compression
Text-based resources should be served with compression, such as gzip, deflate or brotli.
Preconnect to required origins
Resource hints, such as 'preconnect' or 'dns-prefetch', may assist in establishing early connections to important third-party origins.
Use video formats for animated content
Large GIFs are inefficient for delivering animated content. It is recommended to use MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF.
Remove duplicate modules in JavaScript bundles
Ensure that no duplicate JavaScript modules from bundles exist to reduce bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers
Polyfills and transforms enable legacy browsers to use new JavaScript features. For bundled JavaScript it is recommended to adopt a modern script deployment strategy using module/nomodule feature detection. This will reduce the amount of code shipped to modern browsers.

Diagnostics

Avoid chaining critical requests — 29 chains found
Below is a list of Critical Request Chains, which shows which resources are loaded with a high priority. Askci.com should consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load.
User Timing marks and measures
Make use of the User Timing API to measure an app's real-world performance during key user experiences.
JavaScript execution time — 1.0 s
JavaScript (JS) execution time can be lowered by reducing the time required for parsing, compiling and executing JS. Delivering smaller JS payloads may help with this.

Accessibility

Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of askci.com. This includes details about various page attributes that can be optimized.

Navigation

`[accesskey]` values are unique
Access keys assist users with focusing on different parts of the page. Each access key should be unique for proper navigation.
The page contains a heading, skip link, or landmark region
It is advised to provide ways to bypass repetitive content, allowing users to navigate the page efficiently.
`[id]` attributes on active, focusable elements are unique
Ensure all focusable elements have a unique id value to allow them to be visible to users of assistive technologies, like a screen reader.
Heading elements appear in a sequentially-descending order
Properly order all headers and do not skip heading levels to better the navigation and readability for users of assistive technologies, like a screen reader.
No element has a `[tabindex]` value greater than 0
Although technically valid, a tabindex value greater than 0 often creates frustrating experiences for users who rely on assistive technologies.

ARIA

`[aria-*]` attributes match their roles
Avoid mismatching 'aria-*' attributes and their 'role' value, as it invalidates the attribute.
`[aria-hidden="true"]` is not present on the document `<body>`
If aria-hidden=true is set on the document body, assistive technologies, like a screen reader will work inconsistently.
`[aria-hidden="true"]` elements do not contain focusable descendents
Interactive elements within an aria-hidden=true element are unavailable to users of assistive technologies, like a screen reader.
ARIA input fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when an input field does not have an accessible name specified.
`[role]`s have all required `[aria-*]` attributes
Some ARIA roles have required 'aria-*' attributes, which provide essential information about state and functionality.
Elements with an ARIA `[role]` that require children to contain a specific `[role]` have all required children.
Some ARIA parent roles cannot perform their intended functions if specific child roles are not used.
`[role]`s are contained by their required parent element
Some ARIA child roles cannot perform their intended functions if specific parent roles are not used.
`[role]` values are valid
All ARIA roles require valid values to perform their intended functions.
ARIA toggle fields have accessible names
Generic names are announced to users of assistive technologies, like a screen reader, when a toggle field does not have an accessible name specified.
`[aria-*]` attributes have valid values
ARIA attributes cannot be interpreted with invalid values when used by screen readers and other assistive technologies.
`[aria-*]` attributes are valid and not misspelled
ARIA attributes cannot be interpreted with invalid names when used by screen readers and other assistive technologies.
ARIA IDs are unique
Ensure all ARIA ID values are unique to prevent elements from being overlooked by assistive technologies, like a screen reader.

Names and labels

Buttons have an accessible name
Buttons become unusable as they are announced simply as "button" when the button does not have an accessible name, when used by screen readers and other assistive technologies.
Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
No form fields have multiple labels
Having multiple labels for form fields can be confusing to assistive technologies, like a screen reader.
`<frame>` or `<iframe>` elements have a title
Screen reader users and other assistive technology users rely on frame titles to describe the contents of frames.
`<input type="image">` elements have `[alt]` text
Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.
`<object>` elements have `[alt]` text
It is advised that alt text is used on '<object>' elements in order to provide meaning to screen reader and other assistive technology users, as these technologies are unable to translate non-text content.

Tables and lists

`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>`, `<template>` or `<div>` elements.
Screen readers and other assistive technologies may produce poor and inaccurate output when definition lists are not properly marked up.
Definition list items are wrapped in `<dl>` elements
In order for screen readers and other assistive technologies to properly announce definition list items ('<dt>' and '<dd>'), they must be wrapped in parent a '<dl>' element.
Presentational `<table>` elements avoid using `<th>`, `<caption>` or the `[summary]` attribute.
It is advised to not include data elements in tables which are used for layout purposes, as it may create confusion for screen reader and other assistive technology users.
Lists contain only `<li>` elements and script supporting elements (`<script>` and `<template>`).
Use proper list structure to aid screen readers and other assistive technologies.
List items (`<li>`) are contained within `<ul>` or `<ol>` parent elements
In order for screen readers to announce list items, ensure that list items ('<li>') are contained within parent '<ul>' or '<ol>' tags.
Cells in a `<table>` element that use the `[headers]` attribute refer to table cells within the same table.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that '<td>' cells using the headers attribute only refer to other cells in the same table, to improve screen reader user experience.
`<th>` elements and elements with `[role="columnheader"/"rowheader"]` have data cells they describe.
Screen readers and other assistive technologies have features to make navigating tables easier. Ensure that table headers refer to some set of cells, to improve screen reader user experience.

Internationalization and localization

`<html>` element has a valid value for its `[lang]` attribute
Specify a valid BCP 47 language in order to help screen readers and other assistive technologies announce text properly.
`[lang]` attributes have a valid value
Specify a valid BCP 47 language on elements in order to help screen readers and other assistive technologies announce text properly.

Best practices

The document does not use `<meta http-equiv="refresh">`
Pages that refresh automatically cause a poor user experience as focus is directed back to the top of the page unexpectedly.

Audio and video

`<video>` elements contain a `<track>` element with `[kind="captions"]`
Askci.com may provide assistance to deaf or hearing-impaired users with captions on videos.
`<video>` elements contain a `<track>` element with `[kind="description"]`
Askci.com may provide relevant information that dialogue cannot, by using audio descriptions.

Contrast

Background and foreground colors have a sufficient contrast ratio
Many (if not most) users find low-contrast text difficult or impossible to read.

Internationalization and localization

`<html>` element does not have a `[lang]` attribute
It is advised to provide a lang attribute so that screen readers and other assistive technologies are guaranteed to announce the page's text correctly. When not provided, the user's default language setting will be used which may cause inaccuracies.
Failing Elements

Names and labels

Image elements do not have `[alt]` attributes
Provide short and descriptive alternative text where possible on informative elements.

Form elements do not have associated labels
Screen readers and other assistive technologies rely on labels to properly announce form controls.
Failing Elements
Links do not have a discernible name
In order to improve the navigation for screen reader and other assistive technology users, use link text that is unique, focusable and discernible.

Best practices

`[user-scalable="no"]` is used in the `<meta name="viewport">` element or the `[maximum-scale]` attribute is less than 5.
For users with low vision who rely on screen magnification, ensure that zooming is not disabled.
Failing Elements

Manual Checks

The page has a logical tab order
The visual layout should be logical in its tab order and users cannot focus elements that are offscreen.
Interactive controls are keyboard focusable
Ensure that custom interactive controls are keyboard focusable and that a focus indicator is displayed.
Interactive elements indicate their purpose and state
Ensure that interactive elements (such as links and buttons) are distinguishable from non-interactive elements and that they indicate their state.
The user's focus is directed to new content added to the page
When new content (such as a dialogue) is added to the page, the user's focus should be directed to it.
User focus is not accidentally trapped in a region
Avoid focus being accidentally trapped when a user tabs in and out of controls or regions on page.
Custom controls have associated labels
Ensure that custom interactive controls have associated labels, which are provided by aria-label and aria-labelledby attributes.
Custom controls have ARIA roles
Ensure that all custom interactive controls have appropriate ARIA roles.
Visual order on the page follows DOM order
Ensure that the DOM order matches with the page's visual order, in order to improve navigation for screen readers and other assistive technologies.
Offscreen content is hidden from assistive technology
Ensure that offscreen content is hidden through the use of "display:none" styling or the aria-hidden attribute.
HTML5 landmark elements are used to improve navigation
Elements such as <main> and <nav> are recommended as they are used by screen readers and other assistive technologies to improve keyboard navigation.

Content Best Practices

Document has a `<title>` element
Search engines, screen reader users and other assistive technology users rely on the title to provide an overview of the page and to help determine if the page is relevant to their search.
Document has a meta description
Meta descriptions may be used by search engines when displaying a link to the page and should concisely summarize the page's content.
Links have descriptive text
Make use of descriptive link text to assist search engines in understanding the content.
Document has a valid `hreflang`
Search engines can be instructed to list specific versions of a page for a given language or region through the use of hreflang links.
Document has a valid `rel=canonical`
Search engines can be suggested which URL should be shown in search results through the use of canonical links.
Document avoids plugins
The content of plugins cannot be indexed by search engines and many devices either restrict or do not support them.

Crawling and Indexing

Page has successful HTTP status code
Avoid pages with unsuccessful HTTP status codes as they may not be indexed by search engines.
Page isn’t blocked from indexing
Pages that cannot be crawled by search engines cannot be indexed or included in their search results. Ensure that search engines have permission to crawl all pages that should be indexed.
robots.txt is valid
Malformed robots.txt files prevent crawlers from understanding how a site wants to be crawled or indexed, which can be devastating to SEO.

Mobile Friendly

Tap targets are not sized appropriately — 98% appropriately sized tap targets
Interactive elements (such as buttons and links) should be appropriately spaced, sized and easy enough to select or tap with regard to their surrounding elements.
Tap Target Size Overlapping Target

Crawling and Indexing

Links are not crawlable
Ensure that the 'href' attribute of anchor elements links to the appropriate destination. This allows for more pages of the site to be discovered by search engines.

Content Best Practices

Image elements do not have `[alt]` attributes
Provide short and descriptive alternative text where possible on informative elements.

Progressive Web App

Indicates how valid the aspects of a Progressive Web App (PWA) are for the page and highlights opportunities to enable/improve the PWA of askci.com. This includes details about web app manifests.

PWA Optimized

Redirects HTTP traffic to HTTPS
It is advised to redirect all HTTP traffic to HTTPS, in order to enable secure web features for all users.
Content is sized correctly for the viewport
Ensure that the width of the app's content matches the width of the viewport, otherwise the app might not be optimized for mobile screens.
Has a `<meta name="viewport">` tag with `width` or `initial-scale`
It is advised to use a '<meta name="viewport">' tag for the optimization of askci.com on mobile screens.
Contains some content when JavaScript is not available
Apps should display alternative content for when JavaScript is disabled.

Fast and reliable

Page load is not fast enough on mobile networks — Interactive at 33.6 s
Ensure that the page loads fast enough over a cellular network, to ensure good mobile user experience.
Current page does not respond with a 200 when offline
In order for Progressive Web Apps to be made available offline, ensure that the app is using a service worker.
`start_url` does not respond with a 200 when offline
Consider using a service worker for Progressive Web Apps to ensure greater reliability for the user, in the case of poor network conditions.

Installable

Does not use HTTPS — 1 insecure request found
Ensure that all pages are protected with HTTPS (including those that do not handle sensitive data) as HTTPS prevents tampering and passive listening on communications between the app and its users. Additionally, HTTPS is a prerequisite for HTTP/2 and many new web platform APIs.
Insecure URL
http://askci.com/
Does not register a service worker that controls page and `start_url`
A service worker is used to provide Progressive Web Apps the use of features such as working offline, the ability for the app to be added to the homescreen as well as push notifications.
Web app manifest does not meet the installability requirements
User engagement may be increased by leveraging the browsers ability to proactively prompt users to add the app to their homescreen.
View Data

PWA Optimized

Is not configured for a custom splash screen
Themed splash screens ensure a high-quality user experience at launch for app users.
View Data
Does not set a theme color for the address bar.
A theme may be applied to the browser address bar, which ideally can be made to match the site.
View Data
Does not provide a valid `apple-touch-icon`
iOS users of Progressive Web Apps will benefit from an apple touch icon, which can be defined with 'apple-touch-icon', which must point to a non-transparent 192px (or 180px) square PNG.
Manifest doesn't have a maskable icon
Maskable icons are great to ensure that images fill the entire shape when installing the app on a device.

Manual Checks

Site works cross-browser
Ensure that the Progressive Web App works correctly across every major browser.
Page transitions don't feel like they block on the network
Users perceive apps with responsive, snappy transitions as higher peforming and ensures a great user experience, even on a slow network.
Each page has a URL
Ensure that all pages are deep linkable via URL. They should also be unique for the purpose of shareability on social media.
