About Pagespeed Insights Checker | Page speed Checker Tool

information about Our Pagespeed Insights Checker tool!

Make sure your web pages are always fast. Pagespeed Insights Checker is a tool that will help you optimize your webpage for a faster and smoother experience. Pagespeed Insights Checker is a browser extension. It works by checking your webpage on 100+ different mobile and desktop devices with Pagespeed Insights, a service by Google. Web pages are optimized by optimizing the CSS and JS. The tool also has an easy-to-use interface that lets you know how optimized your web page is compared to industry standards.

What is the PageSpeed Insights tool?

- What is the performance score?

Examine your website's performance in terms of speed, identify any bottlenecks, and resolve them so that both users and search engines can access it quickly and easily.

The Website Speed Insights Test provides information, diagnostics, and recommendations on how your page may be improved. It measures how well a webpage performs on desktop and mobile devices.

The performance of the page is summarized in a doughnut chart at the top of the report, which is followed by additional information and a screenshot of the page's final rendering on both desktop and mobile devices.

Running Lighthouse to gather and examine lab data regarding the page yields this score.

A score of 90 or higher is regarded as fast, a score of 50 to 89 as ordinary, and a score of less than 50 as slow.


Along with categorizing field data into 3 buckets, the page speed score also rates user experiences as fast, average, or slow.

  Fast Average Slow
The time that the website's initial content or image is painted is known as the "First Contentful Paint." 0-1000 ms 1000-2500 ms over 2500 ms
Initial Input Delay
maximum capacity The time it takes to complete the longest task is the first input delay users may encounter.
0-50 ms 50-250 ms over 250 ms


  • Following the rendering of the Filmstrip with loading timing (this is how your site appeared to load), the Page Speed Insights Tool offers detailed information in two different categories:
  • Diagnostic: details regarding actions that do not directly impact page speed score; Audits: various datasets and metrics. Each statistic shows information, a score, relevant objects, and recommendations for how to enhance page performance.

DOM size browser Browser engineers recommend that pages include no more than 1,500 DOM elements. A tree depth of 32 elements and fewer than 60 children/parent element is the sweet spot. A big DOM can cause higher memory utilization, lengthier style calculations, and costlier layout reflows.
Defer unused CSS Remove dead rules from stylesheets and delay the loading of CSS that is not needed for above-the-fold content to save network bytes.
Cache policy Use an efficient caching policy to serve static materials. Repeat visits to your page can be sped up with a long cache lifetime. 
Critical Request Chains The Critical Request Chains below illustrate which resources have a high priority. Consider shortening chain lengths, lowering resource download sizes, or postponing the download of superfluous resources to enhance page load.
First CPU Idle The initial CPU idle indicates that the page's main thread is quiet enough to handle input.
First Contentful Paint The time when the first text or image is painted is marked as First Contentful Paint.
User Timing Marks and Measures Consider instrumenting your app with the User Timing API to track your app's performance in real-world scenarios.
Text Compression Text compression reduces the byte size of network responses with text content. Faster page loads result from downloading fewer bytes.
Serve Images in Next-Gen Formats
Image formats such as JPEG 2000, JPEG XR, and WebP frequently compress images better than PNG or JPEG, resulting in faster downloads and less data consumption.
Page redirects Redirections add to the time it takes for the page to load.
Offscreen Images To reduce time to interaction, consider lazy-loading offscreen and hidden pictures after all vital resources have finished loading.
JavaScript Bootup Time Reduce the amount of time spent parsing, compiling, and executing JS. Delivering lower JS payloads may help with this.
Render-Blocking Resources Fast website loading result in increased user engagement, more pageviews, and higher conversion rates. You can enhance page load performance by inlining and delaying links and scripts that are required for initial paint.
Time to Interactive The time it takes for the page to become completely interactive is referred to as the time to interactive.
Preload key requests Consider utilizing to prioritize the retrieval of resources that are currently being requested later in the page load.
First Meaningful Paint First Meaningful Paint detects when a page's major content is visible.
Properly Size Images Your page should never supply images that are larger than the version that is displayed on the user's screen. Anything bigger results in wasted bytes and slows down page load time.
Network Payloads Large network payloads are expensive for users and are substantially connected with long load times.
Input Latency Input responsiveness is an important component in how consumers perceive your app's performance. The user considers the app as laggy if it takes more than 100ms to respond.
Server Response Times Time To First Byte indicates when your server provides a response.
Minify CSS CSS file minification can help to minimize network payload sizes.
Speed Index The Speed Index measures how quickly the contents of a page are visible.
Optimize Images Images that have been optimized load faster and use less cellular data.
