What do you think about following traffic programs?
1. PPC advertising
2. Article submission services
3. 3 way links submission services
4. 1 way link submission services
5. Buy a directory submission software
6. Buy an article submission software
I know the ROI is not only base on the traffic source, I just want to know what you guys think about these programs, which is more or less cost effective.
I think 2,3,4,5,6 are kind of similar, don't you think? They all able to get one way back links, and some direct traffic.
If I have to chose one or two programs among them, which is better?
