We've got some healthy competition around the terms we're trying to rank for, so I'm concerned one of our competitors is doing something to impact our rankings. Before I put my tinfoil hat on...I 'd like a sanity check please! A few days ago we shot up to number 3 on google.com for "hr software". Previously we were hovering around 30th for that term. At the same time traffic to our site tripled. I did 2 + 2 and got 4, thinking that we'd been awarded with higher serps by our google overlords, and this explained the traffic. The next day our ranking for that keyword went back to normal but the traffic kept flowing in... Fast forward four days to today, our rankings for all keywords have dropped across the board but the traffic is still rolling in. On further investigation 82.5% of this traffic is from IE 7.0 and of that traffic 99.73% bounced! It feels to me like we've got some kind of bot (all the visits are from different IP addresses) hitting our site, and leaving immediately, as this would explain the fact that all visits register as IE 7.0 and have almost 100% bounce rate. Has anybody seen this before? Happy to share any other stats and Google Analytics info if it helps solve this mystery!
