Has anyone tried to buy traffic from traffic sellers such as visitorboost and used it on an adsense site? If so what were the returns? Were there any returns?
Instead of thinking on return I would recommend you thinking if it could lead you account to be banned. Please be aware that many banned Adsense accounts are because of buying traffics. Most kind of traffics will be defined as "low quality" from Google perspective.
http://logitraffic.com has the best returns for Adsense. Just don't boost your CTR too high. I keep mine around 5% and make quite a profit
It's against google adsense TOS. Try to get organic traffic rather than buying traffic for your site for adsense purposes.
Google may not really like seeing some floods of traffic generated for the sites taking part in its AdSense program. Instead of using some short term solutions, attempt to work on your site's SEO tasks for sustainable results.
Yep! Don't risk it. What you can do is go for slow growth through updating regularly. I just read a blog at noteworthytips or something like that. The owner changed her site from HTML to wordpress blog and got almost overnight boost to page one of Google. I'm sure there are other variables I'm missing here, but the point is to update your site, and if it is not a blog, you should probably consider changing it to a blog.
