With the launch of Personalized Search, you can use that search history
you’ve been building to get better results. You probably won’t notice
much difference at first, but as your search history grows, your
personalized results will gradually improve.

This whole concept
of personalization has been a big part our lives since some of the team
was in grad school at Stanford. We shared an office, which happened to
be the same one Sergey had used before, and we were pretty familiar
with the research he and Larry had done. Related to their work, we
thought building a scalable system for personalizing search results
presented an interesting challenge. We’ve still got a long way to go,
but we’re excited to release this first step. So check out this latest
addition to Google Labs and tell us what you think.
