Lighthouse, on the other hand, focuses on the synthetic lab data portion. User Data - ****PSI includes data from real users in their results and synthetic lab data when generating reports.Progressive Web App (PWA) - The only report category still unique to Lighthouse is the PWA report that shows if your website qualifies as a Progressive Web App and, if not, what needs to be done to make it one.PageSpeed Insights and Lighthouse have become closer than ever, with only a few notable differences between them. This is because, in the past, Google PageSpeed Insights used to focus on the performance of your website exclusively, but in October 2022, this was changed, and the categories that were exclusive to Lighthouse, such as Accessibility, SEO, and Best Practices were added into PSI's reports. In fact, over the years, the two tools have moved increasingly closer together. Google Lighthouse is a similar tool to PageSpeed Insights in that its sole purpose is to help you improve and optimize your websites to be as performant and accessible as possible. Interaction to Next Paint (INP) - New - How long it takes to interact with the entire page.Time to First Byte (TTFB) - New - How long it takes for the server to respond to a request for a resource.Speed Index (SI) - How fast the contents of a page are visibly populated.Cumulative Layout Shift (CLS) - The amount of movement of visible elements in the viewport after the page has loaded.Total Blocking Time (TBT)- Sum of all time periods between the First Contentful Paint and Time to Interactive.If you'd like to read a dedicated guide on fixing LCP issues, you can do so here. Largest Contentful Paint (LCP) - This measures the time it takes for images and text to appear on the screen.First Contentful Paint (FCP) - Time it takes for the first text or image to appear on the screen.The performance category falls into the following categories.
It's also worth noting that within the performance category of data, you get a more granular breakdown of the data. This then gives you a list of things you can work on to improve to make sure your website is optimized for your users. These categories are divided into individual metrics and improvements that can be made to optimize your page.

From that, was formed.Google PageSpeed Insights is a free-to-use tool that allows users to measure a website's page speed on desktop and mobile devices using real-world data from users and lab data collected by the tool when running a series of automated tests on the URL provided.Īfter PSI has completed its tests, it'll show you a report across four categories for both mobile and desktop devices, the categories are. Having built some websites that required good Pagespeed Insights scores, we got tired of these repetitive tasks getting in the way of more rewarding development work and felt they could be solved by a well designed tool with automation. Very frustrating.Īdditionally, if you have more than a handful of pages it becomes impossible to test them all so most people fall back to testing the homepage and some other URLs they feel are important. However, there is no way to automate this and you have to return to the PageSpeed Insights UI and repeat the process time after time. You can paste a URL and receive a detailed report in 20 seconds about how that page performs in the eyes of Google. PageSpeed insights is a fantastic service for people who operate small websites that don't change very often.
