Yesterday I had a big day of unique visitors to my site, the biggest in a long time. I'm doing some small link building so at first I'm thinking this is typical. Most of the hits came in on terms that I am ranking #1-3 on. I use statcounter, which shows me the position in the serp the user came in from, but doesn't include the search term because lately most are encrypted. So I got all these hits from terms that Im ranking #1-3 and on many inner pages that I don't get much action on. So im like OK cool. I dive a little deeper and most of the "unique visits" came from big G headquarters in CA, all from different IPs, different browsers, search terms, resolution, operating systems etc. I have no idea what keywords cause they're all encryted. I don't use GA. But whatever terms they are using im ranking top 3 and many inner pages too. I checked my webmaster tools and there is no message there. Something seems fishy. Anyone got any idea whats going on, what G might be up to, and what I should expect?
