Oh yay! An affiliate link to use for a so called SEO tool that is not recommended by any one with meaningful insight into the industry.... I have always been brought up on in-house built tools for many things but you want to be looking at the likes of MajesticSEO.com or LinkResearchTools.com to do your analysis of the niche with as these are the power behind backlink reporting. Oh and SEOMoz is a good one too.
