If you've already established significant relevance for a term (because your page is about that term, right), the kinds of tweaking you're talking about are going to have some very minor impact on your relevance score, when it's entirely possible that you will be unable to move up in the SERPS with any amount of improvement to your relevance, without improvement in your offsite factors.

On a website, if making on-page changes cannot help a lot in the rankings if the relevance of a page has already been established, can adding pages to a website that are related to the theme help in the rankings?
