META SEO Inspector is a free Chrome extension developed by Omiod that allows web developers to easily inspect the meta data found inside web pages. It is designed to help developers verify the HTML of their site to follow the Webmasters' Google Guidelines, but it is also useful for anyone who is curious about any page contents that are usually not visible, but can reveal interesting site properties.

With just a click, users can discover all the page meta data, including full json-LD structure, and get advice on how to fix any issues or missing tags. The extension also allows users to easily copy meta tag values to the clipboard, print or export the report, and is available in many languages.

META SEO Inspector is constantly updated and most of the advice will help address 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.

In summary, META SEO Inspector is a valuable tool for web developers who want to ensure their website follows guidelines and for those who want to study competitors.
