Wait so all this does is boost your graph in the stats page... does it have any impact on actual SEO? Does it work on youtube videos too?
Google owns Google Analytics. I asked if the buyers got any SERPs change previously because I highly doubt Google will take fake data into account (they are Google themselves - they know if the searches are valid or not).
This cant have any effect on SEO. Google knows which IPs participate in auto-surf. Those are not accounted for in ranking.
As well as knowing the traffic doesn't really come from the search engine, which should be a red flag. Also, most sites use Google Analytics (including those) so, as you say... they'll know those searches are not valid.
