I'm not too technical or into all this SEO, but I do run a highly successful niche blog that has consistently shown up on google as the 1st - 3rd result for my most important search strings. I have never engaged in any blackhat tactics. A couple of weeks ago, the blog's income has plummeted - I'm suddenly down to the bottom of the first page. I can't imagine why. I decided to check google webmaster tools, and I notice that I have in excess of 8000 links coming to my site from random websites ranging from dental care tips or bbq reviews. I checked dozens of these sites, they have nothing to do with my blog and as far as I can tell exist only to generate backlinks. The last time I checked webmaster tools would have been maybe a couple of months ago, when my links were sitting around the 600 mark. There's really only a handful of serious competitors that I have to contend with, and through process of elimination I have determined which one is responsible for doing this. What options do I have for a) retaliation b) fixing my site Many thanks for any input!
