What value, if any, does the back link keyword, for instance, lingerie have for another back link keyword sexy lingerie or vice versa? If I use the keyword lingerie on a blog post does it in any way help boost the keyword sexy lingerie since they share the same word lingerie? In other words if the anchor text keyword is "lingerie" am I doing any good for the similar but not the same keyword "sexy lingerie"?
lingerie has 78 million competing in results, sexy lingerie has 8 million, personally I'd opt for sexy lingerie and rotate it with sexy lace lingerie, sexy red lingerie, etc, that way you should rank well for it.
