Google, and other search engines use URLs, allong with the page title and the words you use on a page to determine what the content is about. If you are consistent, ie the URL is the same as the page title, which has relevance to the text the page presents you will go up in Google search rankings for those terms.
URLs
When you create a page in epi server it automatically creates a URL using that page name. As you edit and change content these names may no longer be correct, which means your news URL could look like complete gibberish www.gwp.org/my-site/test-page1/cherries-xylophone-collection-copy-4 ... Unless you're writing about the musical properties of a rather esoteric fruit collection this URL is obviously not very useful, or easy to remember.
To fix it, you must check the following on every page before launching a new site, and every time you create a new page:
Open a page to Edit -> Settings and edit the "Page name in web address" field. Make sure it is the same as the page header, and that there are NO spaces or punctuation, (use a dash - instead of a space)
Short-Cuts
If a page is very important (ie it will get allot of traffic) and will not change or be removed you can set up a short-cut. This should ONLY be done for
- Homepages, ex. gwp.org/caribbean is a short cut that points to the caribbean regional hompage
- Fixed features of the site that would otherwise be very hard to find, ex.www.gwp.org/database is a convenient short-cut linking to the Partners database (which has a VERY long and duifficult to remember URL)
