Thanks for sharing the information. I have a doubt related to acklinkwatcher. Can i use backlinkwatcher to view the ranking of a site.
For competitor analysis you can check manually the first 5 sites. If their description has nothing to do with the keywords you have chosen, this niche is SEO free. You also can check MajesticSEO for the top 10 backlinks your competition has( 10 links is free). Once you saw the where the backlinks fo your competition are coming from, you can use these backlinks for your own site
