How can I optimise my key pages for new (related) key phrases as they arise, without compromising the original optimised keywords?

[nicolewretham]

I have an important product page that I've fully optimised for a couple of specific key phrases. There are some other really good (related/similar) key phrases it's starting to rank on the first page for which I'd like to increase ranking on further. How can I optimise/improve ranking for these without compromising ranking for other keywords?

Expand the content with new sections thematically bound to the new keywords. If you dilute your page by making it about too many things, your original ranking could suffer. Be careful how you proceed! As long as the new keywords are highly related to the old one it shouldn't cause too many problems. Another concern would be, expanding the content to the point where the page's performance (loading speed) suffers. If you embed too much non-optimised rich media, that could be a problem. Check your before and after URLs using Google Page-Speed Insights, and learn how to properly optimise images /videos (and other media) before you upload them into your content. Don't 100% rely on CMS plugins to do this for you
