Google: So Long Search Queries, Hello Search Analytics
The Search Queries report in Google's Webmasters Tools is being replaced with a new "Search Analytics" report.
The new report offers the ability to compare desktop and mobile traffic, compare metrics in different countries, and segment data in pretty much any way you want - including between two time frames.
Say for example you believe that Google's most recent algorithm update (which gave a boost to mobile sites) negatively impacted your overall organic traffic. With the new report (seen below), you can confirm that suspicion.
Google did indicate that there are some differences between the Search Analytics and Search Queries reports, revealing (most notably) that data in the Search Analytics report is more accurate (perhaps because it is calculated differently but that's really only a guess). Google will keep the Search Queries report in Webmaster Tools.
