Has anyone used socialmarker.com for backlinks from social media. Its suppose to be free. Not sure if its cool or not?
I have used it.. it works to some degree. But I would concentrate on providing good quality content for your sites.. google likes unique content
I have not used this tool before but it seems me interesting a and widely popular as its PR 5 and Alexa rank is also good.
Most of the social sites are free. They are also good source and all the social sites work same way. I have not try that yet. But if you think, that is useful, no problem to use another new one.
