EDIT: I hit my HN rate limit for the morning, so my response to your comment below follows:
AppleInsider is extremely unlikely to be confused with an Apple website, however. Particularly since it's style is very different, and a "news and rumors" site about Apple isn't likely to be confused for an Apple site. (And as a sidebar, even if Apple did want to C&D them, they'd have a much harder time C&Ding a journalistic presence.)
In the case of yours, I had to check the copyright fine print to determine it was not a Google website.
Even changing the logo and site design from the standard Google corporate style would help.
