In February, we announced the launch of SEO auditing tools in Lighthouse Chrome Extension, which is now available in Google Chrome Developer tools.
Lighthouse is an open-source, automated tool for improving the quality of web pages. Lighthouse is designed to help publishers improve the quality of their web sites, by providing tools and features for their developers to run audits for performance, compatibility, progressive web apps, SEO, and more.
The SEO audit category within Lighthouse was designed to validate and reflect the SEO basics that every site should get right, and provides detailed guidance to fix those issues. Current audits include checks for valid rel=canonical tag, successful HTTP response code, page title and description and more.
