Here is my situation: I got a keyword with 5,000 monthly searches. I am currently ranking on #3 to #5 and trying to reach the top, though for some reason this is quite hard. The Wikipedia article is on #1, but it is a stub (my site is a huuuge article with 3k words and 20 related pictures). I got a well established wikipedia account and could insert my link into that article, but I would also need to flesh things out a bit to warrant that link. would u do it? or am I hurting myself by pushing the relevancy of the wikipedia article.
