META SEO inspector


download at Chrome Web Store

A Google Chrome extension useful to inspect the meta data found inside web pages, usually not visible while browsing.

Meta data is not just the usual HTML meta tags, but the XFN tags, various microformats, the recently introduced canonical attribute, the no-follow links 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.

Alerts are showed 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).
Anyway, in one of the next updates, the links list will be customizable.
