On each page, under "Advanced Settings", you have the ability to give each page it's own title and description. These should directly relate the to content and purpose of the page. Search engines use what you declare as the title and content to categorize this page and this seriously effects your SEO. The 'Page Description' (also known as a Meta Description) is a sentence or two that describes the content of that page. This brief description (not more than 155 characters) will be seen when search results are displayed to the user. This, in turn, will allow a user an idea of what your site contains and will help them make a decision about whether to visit the site.
To fill in the Page Descriptions, go to the go to the “Pages” Tab and select the page. You will need to do this for each page on your site as every page has its own settings. Now, click the “Advanced Settings” link for that page. Your first two options are 'Page Title' and 'Page Description'. This is where you'll fill in the information that is pertinent to that page.
You also have a 'Settings' tab at the top of your site. Information filled in here (under SEO) will apply to your entire site. However, 'Page Settings' can override the overall site 'Settings' allowing you to modify each page (as it changes) without effecting the overall site.
