Amit Singhal, Google’s head of search, Amit Singhal, stated in a Google+ post that Google has made “more than 890 improvements to Google Search last year alone.”
According to Google, they had made between 350 to 400 in 2009, and in 2010, they’d made 550 improvements in the past year. in 2010, Matt Cutts said they would make one change per day to their core search algorithm.
The 890 “improvements” stated in Amit’s post all center around search specifically, but goes beyond algorithms. We’re talking about things like auto-complete, interface changes, and Google Now. Of course, it’s not specifically just these three points, but much more beyond them.
In a news post written by Barry Schwartz were this information can also be found, we will see that Amit also shared his “10 biggest Google search milestones since 2004.” This is pretty much a way to celebrate the ten year anniversary of the Google IPO. You can find the list on Barry’s post, or on Amit’s post as well.
