Easily inspect the meta data found inside web pages, find issues and get advices to fix them.

Meta data is not just the usual HTML meta tags, structured data (JSON-LD, microformats, etc.), the canonical attribute, the no-follow links, header hierarchy and so on. This extension is mainly aimed at web developers that need to verify the HTML of their site to follow the Webmasters' Google Guidelines, but even to who is curious about any page contents that are usually not visible, but can reveal interesting site properties. Most of the advice will help addressing Core Web Vitals issues. Alerts are shown when the meta data is not within certain ranges, for example when the description tag is too short, or too long.
