Learn all about Google Lighthouse, how it works, what it measures, and how you can improve Lighthouse scores for Gatsby and non-Gatsby websites alike.

Of the many ways you can measure performance on the web, be it initial page load time, runtime efficiency of a web app, or server response times, one of the most well-known is the Lighthouse score. We improved the scores we were receiving on the Gatsby homepage by 22.8 points. Here's how we did it.

The 2020 WebAIM Million survey collected data on up to 1200 different technologies used in home pages and examined the results to see if common accessibility errors corresponded with usage of different technologies. One repeatedly stood out as aligning with significantly fewer accessibility issues: Gatsby. Home pages built with Gatsby had 44% fewer detectable errors than the average.
