[Plugin: WordPress Seo-Rank] No Backlinks

Hi,

I am having this problem in a lot of places, but thought I would post here as I am more likely to get a response.

I recently installed this plugin, mainly to check how many back links my site has. I have also tried several online tools for checking backlinks. I know I have at least 100 backlinks to my site, and no tool I am using shows me them.
With this plugin it is also not pulling in Facebook likes or Youtube subscribers. Has given me both page ranks and twitter followers no problem.
this is probably something very simple that I am missing, thanks in advance for the help.
