Google introduced two improvements to the Google Webmaster Console this week. First, Top Search Queries now has historical data and other improvements. In addition to data going back up to six months, the data is updated more frequently, sometimes daily. Secondly, sites which display SiteLinks in Google search results can now manage SiteLinks with the new SiteLinks tool in the console.
I am always impressed with the speed of the tools in the Webmaster Console. Adding historical data does not seem to be a problem for Google, even considering the number of sites they must need to aggregate this for. Google’s systems seem more than capable of keeping up with what ever data the Webmaster tools team wants to throw at them to serve to their users.
