Safe traffic means "not to display ur site (Or ads) to many visitors for a very short amount of time" E.G. "Get traffic per visit" websites (Rotating service)
thanks for the message So is it safe to buy an ad on a site which will send lets say 200 users per day to your site? I dont see any reason why google shud hav a problem if one buys ads which bring in lot of users. what do you say guys?
again to clarify I mean to buy ads or visitors (genuine visitors not fake bots or clicks) to visit a site which has adsense installed on it.
Safe traffic is from search engines ! ...safe traffic is from other sites !! frombanner exchanges ect
