Acerca de Pagespeed Insights Checker

Analyze your page speed metric and make your site faster

Check the performance of your website, find bottlenecks and fix them so that search engines can rank you high.

What is PageSpeed ​​Insights Tool?

Test the performance of your website, find bottlenecks and fix them so that search engines and users can quickly and easily access your web content.

Pagespeed Insights Pro tests web page performance reports on both desktop and mobile devices, providing information, diagnostics, and suggestions on how you can improve your page.

At the bottom of the report, we provide a donut chart that provides scores that summarize page performance, and a screenshot of the final rendering on both desktop and mobile, followed by detailed information.

This score is determined by running SAS to collect and analyze lab page data.

A score of  90  or above is considered fast,  50 to 89  is considered average, and below  50 is considered slow.

The page speed rating also classifies field data into 3 segments describing actions that are considered fast, medium, or slow.

Diagnostics  : information about characteristics that do not directly affect the page speed estimate;After  

rendering the videotape with loading times (this is what your site looked like) Pagespeed Insights Pro provides detailed information in two different categories:

  • Audits  : different metrics and dataset. Each metric displays information, score, items, and suggestions for improving page performance.

Caching policy

Serve static resources with effective caching policies. Long cache life can speed up repeat visits to your page.

Critical request chains

Critical request chains show which resources are being loaded with high priority. Consider shortening the chain lengths, reducing the size of resource loading, or delaying the loading of unnecessary resources to improve page load.

Defer unused CSS

Remove dead rules from style sheets and defer loading CSS not used for top content to reduce unnecessary bytes consumed by network activity.

DOM size

Browser developers recommend that pages contain less than ~ 1500 DOM elements. The best place is a tree with a depth of <32 elements and less than 60 children per parent. A large DOM can increase memory usage, lead to longer style calculations, and cause costly layout refactorings.

First meaningful rendering

The first Contentful Paint marks the rendering time of the first text or image.

First CPU standby

The first idle CPU mode marks the first time the main thread of the page becomes quiet enough to process input.

The first significant paint

Pagespeed Insights Pro measures when the main content of a page is visible.

Input lag

Input responsiveness is a key factor in how users perceive the performance of your application. 100ms per response, if more than this time, the user perceives the application as slow.

JavaScript load time

Consider reducing the time spent parsing, compiling, and executing JS. Delivering small JS files can help you with this.

Minify CSS

Smaller CSS files can reduce the size of the network payload.

Network data

Large network loads cost users real money and are highly correlated with long load times.

Off-screen images

Consider lazy loading offscreens and hidden images after all critical assets have finished loading to reduce your time to interactive.

Optimize images

Optimized images load faster and consume less cellular data.

Page redirects

Redirects cause additional delays before the page loads.

Keyword preloading

Consider using fetching resources to prioritize that are currently requested later on page load.

Correct image size

Ideally, your page should never have images that are larger than the size displayed on the user's screen. Anything bigger just results in wasted bytes and slows down page load times.

Render blocking resources

Faster page loading results in higher user engagement, more page views, and higher conversions. You can improve your page loading speed by inserting links and scripts needed for the first render, and deferring those that are not needed.

Server response time

The time to first byte determines the time at which your server sends a response.

Speed ​​index

The speed index shows how quickly the page content fills up noticeably.

Show images in next generation formats

Image formats such as JPEG 2000, JPEG XR, and WebP often provide better compression than PNG or JPEG, which means faster downloads and less data consumption.

Compressing text

Compression of the text minimizes the byte size of network responses containing textual content. Fewer download bytes means faster page load.

Time for interactivity

Time to interactivity is the time it takes for a page to become fully interactive.

Custom time stamps and measures

Consider equipping your application with the User Timing API to measure the actual performance of your application during key user interactions.

Slow or Fast?

This question would generate interesting discussion in any round of the conversation. However, the purpose of this article is to explain in more detail what Pagespeed Insights

Pro is, especially when it comes to user experience on websites, blogs and apps.

Page loading speed is critical. It is no coincidence that Google and Yandex attach such great importance to this factor when it comes to the ranking of pages in search results.

Even if your site is perfectly designed and you've viewed content over a thousand times to make sure it's clear and understandable enough, your strategy will suffer if you don't have easy, fast pages.

Fortunately, Google has created a tool called  Google PageSpeed ​​Insights that helps you measure (and improve) your site's loading speed  .

Let's find out more about how this feature works and why you need to start using it today to boost your site's speed.

What is Google PageSpeed ​​Insights?

PageSpeed ​​Insights, also known as PSI, is Google's online tool that measures the speed of a webpage loading.

The score  separates the  evaluation of  performance on  mobile  devices from performance on the desktop,  and provides practical guidelines for optimizing page speed.

This makes PSI an intuitive and easy-to-use solution, not to mention free. But some people don't think this is so relevant.

All data collected to obtain such information is collected through the Chrome User Experience Report, which contains information about the actual use of the public network by Chrome users.

What motivates a service like Google PageSpeed ​​Insights?

Two short words that you may be tired of hearing - user experience - summarize Google's work to protect and encourage the creation of faster, lighter pages.

Nobody likes to wait too long to find the information they want in their browser. Think about your own experience: how many times have you been impatient while waiting for a page to load on your phone or even computer?

If you pause to think about it, you will realize that in most cases this was happening, the big "lag" was only a few seconds. So, if 1 second seems like a week to the user, slow sites  negatively affect navigation .

Google doesn't want that, and neither do you. In the end, a bad experience leaves less money on the table.

In fact, Google's latest industry benchmarks of mobile page load speed show that most websites are far beyond perfect. And this is happening in all industries.

This is a good reason for Google to release these metrics to the public so that everyone can see there is a lot of room for improvement.
