I have noticed a definite bias to sites. For example do a search for atlantic city hotels. See the description for the top listing hotels.com. "Hotels.com offers great rates on top " Now why are the rates of hotels.com GREATER than anyone else ? This was deliberate. How does the editorial people know they are great? The word GREAT is not in the page. Next. The top 2 sites are Hotels.com and Expedia.com. They are both owned by the same company.
