Announcing a new print/export option that let you print or save as PDF the report, or simply copy/paste the data in you preferred tool.
Please let me know how this could be improved to meet your needs.

Meta data is not just the usual HTML meta tags, structured data (JSON-LD, microformats, XFN), the canonical attribute, the no-follow links, header hierarchy and so on.

Most of the advice will help addressing Core Web Vitals issues. 

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.

Alerts are shown when the meta data is not within certain ranges, for example when the description tag is too short, or too long.

There are links to info-sites ( mainly SEO-oriented ) pointing to the exact page about the site you are watching. Feel free to request new links, I'll add only the good ones (there are many sites all showing the same data).

Latest changes:

• Head title and description now report the correct length when handling HTML entities.

• Fixed the French translation
