I'm starting to get calls that start like this:
"Hey Dean, have you ever heard of these guys? They say they can get me lots of visitors to my website..."
I've talked with several sellers of traffic lately, and I am currently testing a campaign with one of them myself.
So...if you get solicited by anybody telling you they can get you lots of visitors, or a high search engine ranking...or you've got an opportunity to "own" certain keywords...send them to me first.
I'll talk to them, and if they can convince me that what they're offering has merit, I'll test a campaign with them for our StopYourDivorce.com site first, and let you know how it works out before you waste any money on something that doesn't work.
Hope this helps...
