In our on-page SEO module you learned about the concept of meta information about a page - information about a page rather than displayed on a page. From a classic optimization perspective, the most important piece of meta information is the title of a page. It's position as the only unique piece of information about a page that is designed to be read by humans makes it uniquely powerful.

There are, however, a variety of other attributes of a page that can have a big impact on its rankings. In this module, we will walk through interactive examples for things like declaring the canonical version of a page, controlling a page's indexation and ability to pass link authority, making explicit the language and locale for which a page is designed and controlling features like thumbnails used when a link is shared in external environments like Facebook and Twitter.

These interactive lessons work by providing you with a text area containing some HTML for a page that you will be asked to modify in accordance with what you have just learned. Simply edit the text in the text area and wait for it to turn green when you get the correct answer. If you are not familiar with basic HTML, you may wish to take our interactive module on HTML before beginning this one.
