Speed Test Results

JavaScript execution took 6.4 seconds. When JavaScript takes a long time to execute it can slow down website performance.	Failed	1
The size of the document object model was 1705 elements. A large model can slow down a website by increasing the memory required and time taken to calculate and display changes.	Warnings	2
Some duplicate Javascript was detected. Duplicate JavaScript modules can slow down a website by requiring unnecessary downloads.	Warnings	2
No inefficient animated content was detected. Inefficient animated content formats such as animated GIFs should be replaced by video.	Passed	3
The first contentful paint took 2.2 seconds. This measures how long it takes a browser to render the first piece of content when someone visits a website.	Warnings	2
The time to interactive was 12.3 seconds. This measures how long it takes a page to become fully interactive.	Failed	1
The largest contentful paint took 4.2 seconds. This approximates when the main content of the page is visible to users.	Failed	1
The largest contentful paint image was not lazily loaded. Lazily loading above the fold images can negatively affect performance.	Passed	3
Some legacy JavaScript was detected. Avoid serving legacy JavaScript to modern browsers, only serving it to older browsers that require it.	Warnings	2
The main thread was busy for 10.3 seconds. When the main thread is busy the website may not respond quickly to user interactions.	Failed	1
The first input delay was 0.3 seconds. This measures the time from when a user first interacts with a website to the time when the browser is actually able to respond to that interaction.	Failed	1
Modern image formats null	Not applicable	4
Network server latency A high latency is an indication that the backend server is overloaded or performing poorly.	Not applicable	4
Usage of document.write() was detected. External scripts dynamically injected via document.write() can delay page load by tens of seconds.	Failed	1
Offscreen and hidden images were not lazily loaded. Lazy-loading offscreen and hidden images after all critical resources have finished loading can significantly increase website performance.	Warnings	2
Preloading of optional fonts Preload optional fonts so that first-time visitors can use them and to prevent layout shifting.	Not applicable	4
The largest contentful paint image was not preloaded. The image used by the largest contentful paint element should be preloaded to maximize performance.	Warnings	2
Excessive page redirects were not detected. Avoid multiple page redirects as they introduce additional delays before the page can be loaded.	Passed	3
Render blocking resources Delivering critical JavaScript and CSS inline and deferring all non-critical JavaScript and CSS can help prevent render blocking.	Not applicable	4
The server response time was 0.1 seconds. Server response times can be improved by optimizing server-side code or upgrading server hardware.	Passed	3
The speed index was 4.5 seconds. This indicates how quickly the contents of a page are visibly populated.	Warnings	2
Lazy loading of third party resources Some third-party embeds can be lazy loaded and replaced with a facade until they are required.	Not applicable	4
The total blocking time was 1.7 seconds. This measures the total amount of time that a page is blocked from responding to user input, such as mouse clicks, screen taps, or keyboard presses.	Failed	1
The total page size was 6.3 megabytes (MB). Excessively large page sizes can lead to long load times for visitors.	Warnings	2
Unminified CSS was not detected. Minifying CSS files can reduce payload sizes.	Passed	3
Unminified JavaScript was not detected. Minifying JavaScript files can reduce payload sizes and script parse time.	Passed	3
Unused CSS rules were not detected. Reduce unused rules from stylesheets to decrease bytes consumed by network activity.	Passed	3
Significant unused JavaScript was detected. Reduce unused JavaScript and defer loading scripts until they are required to decrease bytes consumed by network activity.	Failed	1
Optimizing images could improve performance. Optimized images load faster and consume less network resources.	Warnings	2
Preconnects to required origins were detected. Add preconnect resource hints to establish early connections to important third-party origins.	Passed	3
Preloading of resources Preloading of key resources can make your pages load faster.	Not applicable	4
Using responsive images could improve performance. Responsive images that are appropriately-sized save network resources and improve load time.	Warnings	2
Text compression could improve performance. Text-based resources can be served with compression (gzip, deflate or brotli) to minimize network load.	Warnings	2

Accessibility Test Results

Access key values Access keys let users quickly focus on or navigate to a part of the page and must be unique.	Not applicable	4
Definition lists When definition lists are not properly marked up screen readers may produce confusing or inaccurate output.	Not applicable	4
Definition list items Definition list items must be wrapped in a parent element to ensure that screen readers can properly announce them.	Not applicable	4
Attributes on focusable elements are not unique. All focusable elements must have a unique id to ensure that they're visible to assistive technologies.	Failed	1
ARIA IDs are not unique. The value of an ARIA ID must be unique to prevent other instances from being overlooked by assistive technologies.	Failed	1
Form field labels Form fields with multiple labels can be confusingly announced by assistive technologies like screen readers.	Not applicable	4
Frame elements do not have a title. Screen reader users rely on frame titles to describe the contents of frames.	Failed	1
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.	Passed	3
The HTML element does not have a lang attribute. If the website doesn't specify a language correctly screen readers might not be able to read the text correctly.	Failed	1
HTML lang validity Specifying a valid land attribute helps screen readers announce text correctly.	Not applicable	4
Image button alt attributes When an image is being used as a button providing alternative text can help screen reader users understand the purpose of the button.	Not applicable	4
Form elements have associated labels. Labels ensure that forms are announced properly by assistive technologies like screen readers.	Passed	3
Some links do not have a discernible name. Link text that is discernible, unique, and focusable improves the navigation experience for screen reader users.	Failed	1
Lists do not contain only list elements. Lists must only contain list elements so that screen readers can correctly announce lists.	Failed	1
List items are not contained within a parent list. List items must be contained within a parent list for screen readers to properly announce lists.	Failed	1
Zooming and scaling is allowed. Disabling zooming and scaling is problematic for users with low vision who rely on screen magnification to properly see the contents of a website.	Passed	3
Object elements alternate text Screen readers cannot translate non-text such as objects so alternate text should be provided for these elements. `\u003cobject\u003e` elements helps screen readers convey meaning to users.	Not applicable	4
No element has a tabindex value greater than 0. A tabindex value greater than 0 implies an explicit navigation ordering which often creates frustrating experiences for users who rely on assistive technologies.	Passed	3
Table headers markup Screen readers have a specific way of announcing tables and when tables are not properly marked up, this creates the opportunity for confusing or inaccurate screen reader output.	Not applicable	4
Table header data cells When tables are not marked up semantically and do not have the correct header structure, screen reader users cannot correctly perceive the relationships between the cells and their contents visually.	Not applicable	4
Lang attributes Specifying a valid lang attributes ensure that text is pronounced correctly by a screen reader.	Not applicable	4
Video elements contain a track element with captions. When a video provides a caption it is easier for deaf and hearing impaired users to access its information.	Passed	3
