Eliminate render-blocking resources Resources, such as JavaScript and style sheets, can block the first paint of the page. Kerrang.com should consider delivering critical JavaScript/style sheets (JS/CSS) inline and deferring all non-critical JS/CSS.
Properly size images Images can slow down the page's load time. Kerrang.com should consider serving more appropriate-sized images.
Defer offscreen images Time to Interactive can be slowed down by resources on the page. Kerrang.com should consider lazy-loading offscreen and hidden images.
Minify CSS Cascading Style Sheets (CSS) files can contribute to network payload sizes. Kerrang.com should consider minifying CSS files.
Minify JavaScript JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Kerrang.com should consider minifying JS files.
Reduce unused CSS Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. Kerrang.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.
Serve images in next-gen formats — Potential savings of 61 KiB Image formats like WebP and AVIF often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.
| URL | Resource Size (Bytes) | Potential Savings (Bytes) |
|---|---|---|
| https://images.kerrangcdn.com/images/2022/08/TheChats-EsmeSurfleet-2022.jpg?auto=compress&w=1600 | 333477 | 62075.2 |
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.
Initial server response time was short — Root document took 430 ms Keep the server response time for the main document short because all other requests depend on it.
| URL | Time Spent (Ms) |
|---|---|
| https://www.kerrang.com/ | 429.517 |
Preload key requests Key requests can be preloaded by using '<link rel=preload>'. Kerrang.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 Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers — Potential savings of 19 KiB Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

Accessibility
Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of kerrang.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 All focusable elements must have a unique `id` to ensure that they're visible to assistive technologies.
Heading elements appear in a sequentially-descending order Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies.
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.
`button`, `link`, and `menuitem` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[aria-hidden="true"]` is not present on the document `<body>` Assistive technologies, like screen readers, work inconsistently when `aria-hidden="true"` is set on the document ``.
`[aria-hidden="true"]` elements do not contain focusable descendents Focusable descendents within an `aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. [.
ARIA input fields have accessible names When an input field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `meter` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `progressbar` elements have accessible names When a `progressbar` element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[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 When a toggle field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `tooltip` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `treeitem` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[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 The value of an ARIA ID must be unique to prevent other instances from being overlooked by assistive technologies.
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 Form fields with multiple labels can be confusingly announced by assistive technologies like screen readers which use either the first, the last, or all of the labels.
`<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.
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 alternate 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>`, `<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.
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 `[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"]` Kerrang.com may provide assistance to deaf or hearing-impaired users with captions on videos.
Names and labels
Image elements do not have `[alt]` attributes Provide short and descriptive alternative text where possible on informative elements.
| 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.

Eliminate render-blocking resources Resources, such as JavaScript and style sheets, can block the first paint of the page. Kerrang.com should consider delivering critical JavaScript/style sheets (JS/CSS) inline and deferring all non-critical JS/CSS.
Properly size images Images can slow down the page's load time. Kerrang.com should consider serving more appropriate-sized images.
Defer offscreen images Time to Interactive can be slowed down by resources on the page. Kerrang.com should consider lazy-loading offscreen and hidden images.
Minify CSS Cascading Style Sheets (CSS) files can contribute to network payload sizes. Kerrang.com should consider minifying CSS files.
Minify JavaScript JavaScript (JS) files can contribute to network payload sizes and increase script parse times. Kerrang.com should consider minifying JS files.
Reduce unused CSS Dead and/or unused rules in Style Sheets (CSS) can contribute to network payload sizes. Kerrang.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.
Initial server response time was short — Root document took 470 ms Keep the server response time for the main document short because all other requests depend on it.
| URL | Time Spent (Ms) |

Preload key requests Key requests can be preloaded by using '<link rel=preload>'. Kerrang.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 Remove large, duplicate JavaScript modules from bundles to reduce unnecessary bytes consumed by network activity.
Avoid serving legacy JavaScript to modern browsers — Potential savings of 19 KiB Polyfills and transforms enable legacy browsers to use new JavaScript features. However, many aren't necessary for modern browsers. For your bundled JavaScript, adopt a modern script deployment strategy using module/nomodule feature detection to reduce the amount of code shipped to modern browsers, while retaining support for legacy browsers.

Accessibility
Indicates how accessible the page is and highlights opportunities where the page can be made more accessible to users of kerrang.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 All focusable elements must have a unique `id` to ensure that they're visible to assistive technologies.
Heading elements appear in a sequentially-descending order Properly ordered headings that do not skip levels convey the semantic structure of the page, making it easier to navigate and understand when using assistive technologies.
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.
`button`, `link`, and `menuitem` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[aria-hidden="true"]` is not present on the document `<body>` Assistive technologies, like screen readers, work inconsistently when `aria-hidden="true"` is set on the document ``.
`[aria-hidden="true"]` elements do not contain focusable descendents Focusable descendents within an `aria-hidden="true"]` element prevent those interactive elements from being available to users of assistive technologies like screen readers. [.
ARIA input fields have accessible names When an input field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `meter` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `progressbar` elements have accessible names When a `progressbar` element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[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 When a toggle field doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `tooltip` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
ARIA `treeitem` elements have accessible names When an element doesn't have an accessible name, screen readers announce it with a generic name, making it unusable for users who rely on screen readers.
`[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 The value of an ARIA ID must be unique to prevent other instances from being overlooked by assistive technologies.
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 Form fields with multiple labels can be confusingly announced by assistive technologies like screen readers which use either the first, the last, or all of the labels.
`<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.
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 alternate 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>`, `<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.
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 `[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"]` Kerrang.com may provide assistance to deaf or hearing-impaired users with captions on videos.
Names and labels
Image elements do not have `[alt]` attributes Provide short and descriptive alternative text where possible on informative elements.
