The Rollyo web site allows a way for anyone to create and save a customized search of several web sites at once. This is a great way to consistently search only the web sites you wish, rather than searching the entire world wide web. Users have the option of sharing these saved search with others, so you can discover helpful search strategies that have already been created.
Unfortunately, Rollyo puts a lot of extra adds at the top and smack dab in the middle of search results. This makes for a busy and hard to read page.
I created a Rollyo for searching my favorite Disney Vacation Planning Sites.
