Anyone familiar with On Page SEO?

You might try creating more keyword dedicated inner pages instead of messing with a successful home page, write a post, optimizing the meta title, header, tags, and content with a primary keyword in mind, you can write for your audience without getting too spammy in your keyword use and still rank well with less chance of being penalized. There are few online tools that will analyses your on page optimization, though I would not rely on old keyword density guidelines, tougher standard and the increased use of human reviewers makes artificial looking content more risky.

An advantage of SEO for inner pages, if you get an "unnatural link pattern" warning due to your backlinking strageties, it's easier to shedthe backlinks going to an inner page, by just changing it's resuls, while you are stuck with links to your home page, where it's best to only get quality backlinks,
