Interesting article by Matt Cutts and the Google blog refering to the way Google handles synonyms. "think about the different words that searchers might use when looking for your content. Don’t just use technical terms–think about real-world terms and slang that users will type. For example, if you’re talking about a “usb drive,†some people might call it a flash drive or a thumb drive. Bear in mind the terms that people will type and think about synonyms that can fit naturally into your content. Don’t stuff an article with keywords or make it awkward, but if you can incorporate different ways of talking about a subject in a natural way, that can help users." Google does more with “semantics†and both document and query understanding than almost any other search engine. “Pictures†and “picture†often mean the same thing, but the query [arm reduction] is very different than [arms reduction]. Also, in the query [dura ace track bb axle njs] the “bb†is probably referring to a bottom bracket while in the query [software update on bb color id] the “bb†probably means blackberry.
