thanks for your answer. Hope that more people will use it... I personally just have started today, but I am fully aware it needs a lot of time and it is just another factor in our SEO activity BTW I found a bug I think. The bot stops working when there are no results in Google for some search phrase. I noticed it twice today: there are some campaigns in the system for search phrases which do not return any results in Google's SERPs. And then nothing happens, I have to close and then run PSB manually in order to start working again.
