SEO SEO is a useful and easy-to-use Firefox extension that helps you view important meta information of web pages quickly and easily. The extension extracts and displays the title, description, canonical link and index/noindex status of a web page so you can capture this information at a glance. SEO SEO is perfect for web developers, SEO experts and anyone interested in the meta details of a website.
Main functions:

Displays the title of a web page: Find out at a glance what title the developers of a web page have set.
Displays the description of a web page: Discover the meta description of the web page that is displayed in search engine results.
Displays the Canonical link of a web page: See which Canonical link (if any) has been set by the developers to avoid duplicate content.
