My question is specific to writing articles UNRELATED to the site you are trying to backlink. If you write articles unrelated to the site your are trying to backlink, does this deduct from the power of the backlinks themselves? If you write an article that isn't related to the site you're trying to get back links for, should you fill the "about author box" with a lot of text relating to the back link to give it some context, or is it enough to just have the link with the keyword phrase as the anchor text? I guess what i'm saying is does the surrounding context of article back links give the back links any strength beyond the link text itself?
For example, is it enough to have: "Find examples at example.com" orr is it better to write a small paragraph about "examples" to give the back link some context? Does it add to the power of the back link at all to do this?
So far all my "author boxes" for my articles have just been "blah blah blah at example.com" very short
