Say I search for something in Google and click on a few results. After some time, if I again search for same thing, the search results show the earlier clicked links with different colours and date/time of visit. And, I know that this is associated with my Google account and not with the computer as such.
I had in mind that after the search, Google returns us with a page and clicking on those search results does not go through Google. So how does Google keep the web history?
