About Pagespeed Insights Tool

Functionality is the most important aspect of any website design, and one area that should never be overlooked is the page speed factor. However, When it comes to many websites, web designers focus on how attractive the website looks. Many webmasters focus on the stylistic elements and coding of the website’s design and this can sometimes cause a delay in the rendering of the website pages. Anything from code that’s written poorly to images or large page elements affect website load time and that in effect affects Google rankings.

It’s now important more than ever that online businesses understand how to optimize certain content for different users to better ensure they can maximize the performance of their websites, especially when many users are finding website contents through search engines. Now, one of the key measurements the search engines like Google and Bing use in ranking websites is their ability to return responses quickly and accurately. This measurement is called Google PageSpeed Insights.

What is Google PageSpeed, and How is it Measured?

There are many ways the speed of a website is measured and there are many tools out there for measuring this. Some of the best speed testing tools are Pingdom Speed Test, Google PageSpeed Insights, WebPageTest and more. One of the best speed tools for meausuring the overall speed of a website is the Google PageSpeed Insights Tool. Google PageSpeed Insights is a ranking factor that takes speed on mobile and desktop into consideration. See Google's Official Tool.

Google PageSpeed Insights is created by Google and it measures the time taken from the moment a website is requested in the browser to the moment when it is rendered and ready for input in the browser. It scores a web page based on different metrics and gives it a score after assessing it through it's own PageSpeed Insights API service.

PSI runs performance analyses on your website and use data from real users through the Chrome User Experience Report (CrUX) which represents how real people experience your website. If you dont have much data, it loads your website in a simulated environment. It returns with a Google’s PageSpeed Insights score, which is the average of different measurements of the page-load experience. The metric is based on Google's view of how a web page should be constructed to load fast, offer a pleasant user experience with good code quality underneath.

It is important to point out that there is a difference between Google PageSpeed Insights and a website page speed or site speed. A website Page speed refers to the time it takes for a web page to load without the need to check the underlying code. This can be measured by the naked eye and testing tools like SEOCentralTools Page Speed Tool.

Google PageSpeed Insights, on the other hand, refers to the algorithm score from 1-100 that Google gives a website when tested through their PageSpeed Insights API, a web tool that measures loading speed while also checking front end user experience and underlying code.

Google PageSpeed Insights (PSI) uses Lighthouse to analyze any entered URL, generating a performance score that estimates the webpage's performance on some of the most important metrics, including: First Contentful Paint, Largest Contentful Paint, Speed Index, Cumulative Layout Shift, Time to Interactive, and Total Blocking Time.

It provides a score which summarizes the web page’s simulated performance. This score is determined by running Lighthouse to collect and analyze diagnostic information about the web page. A score of 90 or above is considered very good. 50 to 90 is a score that needs some improvement, and below 50 is considered poor.
There are Top 6 measurements of Google PageSpeed:

  • First Contentful Paint (FCP): Measures the time at which a display element is displayed in the browser for the first time.
  • Largest Contentful Paint (LCP): Measures the time it takes to load the main content on a web page.
  • Total Blocking Time (TBT): Measures a web page's load responsiveness to quantify how long a page is non-interactive prior to becoming interactive.
  • Time to Interactive (TTI): Measures the time it takes for the website to be rendered and ready for user input.
  • Speed Index: Speed Index measures how quickly content is visually displayed during page load.
  • Cumulative Layout Shift: Meaures the movement of visible elements within a viewpoint.

The overall score takes the average of all the metrics above and more and gives a result that shows if a particular website is both technically up to speed and provides the right user experience.


How Do Google PageSpeed Scores Impact SEO?

Every online user loves a fast loading website. A fast loading website not only increases a website user experience but also increases the conversion rate. A website that is slow will cause a user to click back, which increases your bounce rate. Nothing decreases the reputation of your website faster than high bounce rate in the eyes of Google. When it comes to building a conversion rate and search engine optimized website, speed is crucial.

Since Google focuses on user experience more these days, it now uses page speed to rank websites. The loading speed of your site now plays a significant role in SEO, but it’s important to realize that your site’s Google PageSpeed score is not the same thing as your site speed. Your sitepeed can be analyzed using the SEOCentralTools Page Speed Tool. The PageSpeed Insights service measures user experience with an emphasis on mobile but also on desktop.

If you want your site to appear at the top of the organic search results, or for your adverts to be served ahead of your competitors, you need to make sure that your website loads quickly and can return values back to search engines as fast as possible.

When PageSpeed Insights Tool crawls your website, it takes a look at all the backend coding of your website and makes a recommendations that is meant to make your website faster. The data for the page speed assessment comes from real users. It’s collected by the Chrome User Experience Report (CrUX) and represents how real people experience your site. That’s why Google uses it as a ranking factor.

It gives your website a page score from 0-100 based on these recommendations, categorized as "good", “Needs Work,” and “Poor”. If a website is slow, it will receive a low Page Speed Insights score from Google. Google and others use this to help determine your website’s search rank or whether to serve your ads.

Google uses the PageSpeed Insights metric as one of the ranking signals in their algorithm, so a website with high PSI score can gain good position in the search results. When you have two websites with equal things between them, the one with the better PageSpeed Insights score will be ranked higher.

How to Interpret your Google PageSpeed Insights Scores

While the score itself is not indicative of how fast your website is running or how well it is performing for your users, Google PageSpeed Insights is still a great tool for diagnosing website speed issues.

Understanding your score can help you know where you need to make improvements so that your users have the best experience possible with your website. For the optimization score and the Lab Data section, PSI runs a test on a predetermined device and network settings. Based on this test, PSI computes the lab metrics, which in turn make up the optimization score.

To improve your PSI scores, this means JavaScript, third-party applications, and any other dynamic media must be optimized for speed. Things like Optimization of large images, Elimination of render-blocking Javascript/CSS files, Leveraging of browser caching and so on.

Also, make sure to monitor your website’s performance after changing something in its code or adding third-party plugins, tools, or libraries. These changes often create speed issues, which can remain undetected for a long time.
