I compared my site home page against my competitor homepage with Open Site Explorer and I found that according Open Site Explorer I have only 3 backlinks where in MajesticSEO I have more than 100 backlinks in 'Historic' data and more 90 in '30 days fresh data'.
Why there is no even close correlation between MajesticSEO data and Open Site Explorer?
How SEOMoz count backlinks?
