Google has updated the Webmaster Tools and the main focus of this update is search query data. Specifically, it now gives access to all search queries that your websites appear for in the organic search listings as well as the impression and CTR data for them. That’s a huge amount of information that is close to what you get in Adwords for your PPC campaigns.
So what that means to us Internet marketers? Until now, we only had broad estimates of click through rates we had from the SERPs, and only if we ran PPC campaigns for the same keywords could we have had more accurate data. Regardless of that, we had no ability to see the exact CTR nor properly test our listing copy for improvement.
