Unfortunately, we don't allow site specific talk in this section of the forums. Hence, we won't be able to give you the exact URLs of the services.

However, I would not recommend that you buy traffic. PPC traffic always converts better.

Most of that bulk traffic aren't real visitors, anyways. Instead, they're computer driven bots or such. It almost never converts as these fake visitors don't visit more than the landing page.

You can test this out by creating a page on your site and don't put anything on it except for a single enticing link. Then, buy a small package of these bulk visitors for a few bucks and send them off to your test page. You'll notice that just about 100% don't click on the link.

(As you can imagine, one of the reasons we don't allow site specific talk is you can see how easily a thread could turn into deflamatory talk about a company and end in bashing wars.)

Adword is good way to get targeted traffic almost you can instantly use it to start making sales as well as to test your site and make sure you're converting.

I can provide low cost quality traffic that are real visitors and much lower cost than PPC

Whats the point of such visitors, I have experimented with a few sites which claim to sell traffic but there has been no increased sales or increased registerations to suggest that the return on investment was good, I honestly would never recomend a traffic reseller because in my opinion it just doesnt work.

I am using now Adwords. I will be able to tell more about it in few days, since I have just started.

I just did what Dani said, and paid $10 for 1,000 visitors.

Results -
572 "unique" visitors showed up.
0 clicked links, of any kind.
Mostly Asian and South American visitors.

So now aren't you glad you didn't say "oh, wow, cheap visitors! let me buy a whole load of 'em!" You get what you pay for I guess.

I did not spend a boat load of money, because eventhough I read many people saying it was great service, and read just as many terrible notes - I could not decide what was true. At $10, I bought myself "truth".
