So I got carried away and set IBP off on my site looking for rankings on co uk google, all seemed well and after about 40 minutes it came back with some interesting observations. However, not long after that I kept getting the we're sorry message from google - it must have detected the IBP scan and flagged me as breaking the terms of service. So what is the limit - none or some or maybe limit to 10 or 20 keywords? Is there anything in lengthening the human emulation times? I guess if I was a google programmer I would spot the exact time gaps and know it was an automated query and then throttle. Does this go against the IP address - I'm behind BT so how do they control it - has my IP been flagged and then everyone on that IP also gets the warning? How does that work?
