Just started a new backlink campaign and my google ranking went from 110 to 70 to 55 to 80 to 345 to gone and my blood pressure with it lol. Anyway I am ranking top 30 in bing and yahoo for a key word that has 100k monthly search results in bing. What is the most effective strategy to dominate bing? I read that anchor text concentration matters most in bing, but my key word density is already in the high 20%'s for my primary term. I am currently diversifying my anchor text for google. I need a strategy that will dominate bing and yahoo but not get me slapped by google.
