I wasn't aware that purchasing traffic was a violation of Google's policies but even if it wasn't, it's always better to try and draw in traffic from free methods (advertising on forums, writing articles and submitting them, etc.). Just remember that when it comes to earning revenue with Adsense, there is never a guarantee that visitors will click on ads, paid or otherwise.
Tsaadmin said that not be from Asia, Pakistan, India etc. Tsaadmin is right, I am from Asia, most of our people can not speak english, so you do not buy traffic from us. I bought the traffic from PTC, although they have low quality traffic but it is good to make backlink or reduce alexa rank from 12.000 untill 1000. I know that it is no good for google adsense. Tos Google can not allow to buy PTC traffic.so I can not put adsense code to mywebsite So you are carefull to buy traffic for adsense, I think there are many PTC sell this traffic.
That's all there is to say about it. Usually, you'll find it hard to buy decent traffic, unless you pay for it too much. You're better off building your own traffic of quality and value.
your most likely gonna get banned if you buy too much traffic. if you do it keep it low an at a good amount
