In my opinion, may be would be great result with one way link not just exchange link. And how can build one way link, we can learn and practise here ... example: make dummy blog, directory submited, blog commenting, etc with free or paid
I am not sure of your question but i am trying to explain it . link exchange is what you request other to put your link in their site and your put their link in turn.
I also know this meaning for link exchange. But how can i do ? For example, i give my website here, and i want to make exchange, and there's someone also want to change, what i should do?
