I was checking the uniqueness of my wordpress.com blog http://hostgatorcouponcodes2012.wordpress.com/ on copyscape.com and it has found 6 results and it is strange, because I don't have the keywords like "MMA Girls" or "e l e c t r i c - a v e n u e . c o m" on my blog. I have also checked the source code of the Google cached version of my blog and I don't see such keywords there. Anyone knows what could be the problem? You can check my blog and also check it on copyscape: http://copyscape.com/?q=http://hostgatorcouponcodes2012.wordpress.com/
actually it also happen with me. Don't worry, the fact is some common keywords will match which is not from an article. Like your widget heading, if its like "Share this article" it will be matched with some other site. I found from my website also. and i think its not a big deal, main fact is article
