I need targeted traffic to be adsense safe and cheap?

[b]

Finding top targeted traffic on the web is definitely a great challenge. I have spent many nights researching information on the same thing. It has been somewhat safer with social networks especially with people you have had a chance to develop a rapport or have known in the past. Sometimes they can give great referrals. However, depending on what kind of traffic you are seeking, it may be helpful to get into forums, blog and meet people who have your same interest.
