Lighthouse is a free, open-source tool developed by Google that helps you improve the quality of your web pages. It can be run as a Chrome Extension, from the command line, or as a Node module.
Lighthouse analyzes your web pages and provides recommendations for improving their performance, accessibility, and SEO. It does this by running a series of audits and generating a report with detailed information about the page's performance, including metrics such as the time it takes to load the page, the number of requests made to the server, and the size of the page's assets.
One of the key benefits of Lighthouse is its ability to identify common issues that can negatively impact SEO. For example, it can detect if a page takes too long to load, if the page contains broken links, or if it has a low text-to-HTML ratio. All of these issues can affect a page's ranking in search engines, so it's important to identify and fix them as part of an overall SEO strategy.
In addition to performance and SEO, Lighthouse also provides recommendations for improving the accessibility of your web pages. This includes things like ensuring that the page is usable by people with disabilities, using semantic HTML tags, and providing alt text for images.
Some of the most important data that Lighthouse provides includes:
