Page properties include the title, description, and keywords that are used to tell search engines about each page. You can change these values for each of your pages by selecting the Edit button, and choosing Edit Page Properties from the drop-down menu. This will open the Edit Page Properties dialog.
Each title should be brief and descriptive to attract potential visitors to your page.
Descriptions are used by most search engines to give potential visitors more information once you have their attention. Keep them short and relevant, as you are limited to a varying number of characters depending on each search engine.
Keywords should be a list of comma-separated words and phrases that relate to the content of your page. You may add as many keywords as you like, but three to five are usually sufficient.
