I am using cheap pay per click search engine to drive traffic to my site. I use some common keyword like "free stuff". But I noticed 50% of visitors are from skeleton domains with porn links/search results. I noticed those porn visitors do visit my site and browse and click on some adsense links. I read adsense TOS couple of times, and do not believe this situation violate the TOS. I do not have any adult material on my site, it's just that visitors may come from an adult referral link. What do you guys think? I should be alright?
As long as the vistors come to your site from a CLICK it should not matter where that click comes from. Many porn sites link to legit nonporn websites. However if these porn sites are auto forwarding or poping up your website. While these are not technically a violation on Google side. I've noticed some pcc search engines allow their affiliates to do this. Just don't uses those ppc engines - Not only are you getting ripped off by not getting targeted text clicks but your traffic is coming in non targeted and quite BAD so your CTR will be in the toilet paying 5 cents for an adwords click mayb be worth more than buying 20 1 cents clicks on some of the lesser than engines.
