Something I hadn't noticed before is that FireFox, Opera and Safari show results as they were prior to the May 25th refresh and Chrome is more positive toward us using the same location (United States). My previous post may have been partly BS because I did all of last night's and this morning's queries in Chrome. For IE I had to delete the browsing history several times to get logged out of Google accounts but those results don't appear to have changed since yesterday either.
Chrome is the only browser showing a noticeable change in OUR SERPs from the previous month. One might associate increased popularity of the browser with the increase in traffic for keyphrase CTR but our pre-Penguin % for browsers hasn't fluctuated except that IE went down 2.3% and Android went up 2.4% - Chrome shows a .23% increase that isn't commensurate with the increase in Unique #s.
