I think traffic buying is going to a site like facebook, google adwords and buy ad space. I don't really understand your question. You want to buy traffic?
I Mean to say ,Heard the word " Traffic Buying " from my opponents .They are not going to do any paid campaigns ,simply targeting on Buy the Traffic ..
To buy traffic is to pay to have visitors sent to your site. It can be banners, adwords, pop-unders, and many others
You can get into other methods for your traffic, such as link, banner, or traffic exchanges and even Pay per Click. You can also purchase traffic directly. While I have stated before that you should be willing to give up some cash, to ask that you give up hundreds of dollars on a relatively new blog won’t accomplish anything. Pay per Click is a potentially dangerous game and requires some serious planning for it to be done correctly, so you should read up on that before trying it.
The most appropriate option to get the full knowledge about the "Traffic buying" is searching on Google . That would also brought instant results with guidelines from professionals. Here to get the full knowledge, you need a long time. If I say frankly, posting such a thread is not seems really comprehensive & beneficial. People (like me) can guess that you might posted this thread just to increase your post count on DPF.
