Where do you purchase traffic?

Maybe their is a good bulk traffic provider out there (doubtful,) but I sure haven't found them. I'd say you're better off with something like Adwords. You get far fewer visitors for the same price, but there is hope that some of those ones will convert!

 

Unless it's targeted traffic you'll have a high bounce rate and it'll be worthless.

 

I think you should go for Adsense if you want quality traffic...people who are really interested in your products..it may be expensive but it gives returns..
