it means that google takes into account your personal browsing history.
I was wondering about this. At first glance you'd expect your own site to come up near the top in your own searches, assuming that your sites are on topics you're personally interested in.
But let it go on long enough, and the search engine is bound to notice that you never click on results from such-and-such domain, even if the content seems a perfect match for your search terms. (You don't want to go there. You've already been there. You just want to see where it ranks.) So wouldn't they stop including those results?
