You people have tried so many Link Building techniques to get a good traffic, but often you would have been failed to get the desired quality and quantity on your site. You have got so many inbound links, as well, with a thought to raise the traffic, but again, it would not have been the result you have expected. What I tell you to do is, try to buy relevant traffic with a PPC (Pay Per Click) campaign. Relevant traffic will get your site more visitors and brand exposure. When people come to your site, regardless of the channel in which they found it, there is a possibility that they will link to you.
Suggestions and thoughts are readily welcome.
