SERP Analytics is still in beta version, but you can rely on this tool. There are 3 available search engines, Google, Yahoo and Bing. Google fo Google.com (Google has a localization data center). I think, the result is more valid because it’s not affected by your Google account cookies. As we know that SERP is saved in personal Google account, when you searching for something in logged in account, your SERP is not objective.
