Accessibility
Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of link4earn.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.
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.
`[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-*]` 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.
Audio and video
`<audio>` elements contain a `<track>` element with `[kind="captions"]` Link4earn.com may provide assistance to deaf or hearing-impaired users with captions on audio elements.
`<video>` elements contain a `<track>` element with `[kind="captions"]` Link4earn.com may provide assistance to deaf or hearing-impaired users with captions on videos.
`<video>` elements contain a `<track>` element with `[kind="description"]` Link4earn.com may provide relevant information that dialogue cannot, by using audio descriptions.
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.
Image elements have `[alt]` attributes Provide short and descriptive alternative text where possible on informative elements.
`<input type="image">` elements have `[alt]` text Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.
Form elements have associated labels Screen readers and other assistive technologies rely on labels to properly announce form controls.
Links 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.
`<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.
Contrast
Background and foreground colors have a sufficient contrast ratio Many (if not most) users find low-contrast text difficult or impossible to read.
Tables and lists
`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>` or `<template>` 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.
Best practices
`[id]` attributes on the page are unique It is advised to keep all id attributes unique in order to prevent instances from being overlooked by screen readers and other assistive technologies.
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.
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.

First Contentful Paint (3G) — 6928 ms The time taken for the first image or text on the page to be rendered while on a 3G network.
Accessibility
Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of link4earn.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.
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.
`[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-*]` 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.
Audio and video
`<audio>` elements contain a `<track>` element with `[kind="captions"]` Link4earn.com may provide assistance to deaf or hearing-impaired users with captions on audio elements.
`<video>` elements contain a `<track>` element with `[kind="captions"]` Link4earn.com may provide assistance to deaf or hearing-impaired users with captions on videos.
`<video>` elements contain a `<track>` element with `[kind="description"]` Link4earn.com may provide relevant information that dialogue cannot, by using audio descriptions.
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.
Image elements have `[alt]` attributes Provide short and descriptive alternative text where possible on informative elements.
`<input type="image">` elements have `[alt]` text Input buttons with alternative text assist screen readers and other assistive technology users to understand its purpose.
Form elements have associated labels Screen readers and other assistive technologies rely on labels to properly announce form controls.
Links 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.
`<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.
Contrast
Background and foreground colors have a sufficient contrast ratio Many (if not most) users find low-contrast text difficult or impossible to read.
Tables and lists
`<dl>`'s contain only properly-ordered `<dt>` and `<dd>` groups, `<script>` or `<template>` 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.
