Search engines might rank a page slightly higher if its URL contains a phrase used in the search. To set your page alias, Click the "Page" button found in the control bar and select "Edit Page Name." Under "Properties" you will see a 'Page URL Alias' field.
Note: Use underbars to make it easy for search engines to figure out what you mean. ?section=fremonthypnotherapist can qualify in a search for a hyp rapist in fremont. Using an underbar as in ?section=fremont_hypnotherapist lets the engines know how to interpret the phrase.
