The properties of your page give important information to your visitors and to some extent search engines making your page easier for them to index resulting in more traffic!

Depending on which search engine 'expert' you speak to, different properties have more effect than others. The general rule seems to be they are all worth including but page title is the most important to get right.

Page title

This is the description of your page that is visible at the top of your browser. Its worth spening a bit of time getting this right as search engines will pick it up and it's what will appear in users bookmarks.

When you click Set you will need to Preview your page to see the changes.

Description: and Keywords:

When you create a Description of a page and add Keywords, they are not viewable to your visitors, but it is added to the code of your page and is read by search engines and the likes.
