Update (27 June 2016): Entrecard shut down at around 2012. After a long time blogging and using these blogging networks, I found out that they simply don’t work.
Probably now there are other perhaps more sophisticated blogging networks or widgets but I think that they will work the same, people click your link just to get points and the leave immediately, even before the site loads completely
I don’t recommend this kind of traffic, but I would like to hear from you if you use such networks and if they work for you.
In this post I’ll try to answer to that question because there is a lot of buzz around Entrecard and I don’t know if it’s worth the time. I explain how the hole system works, and how you can use it to drive traffic to your site or blog.
