When optimizing for a keyword, what would be a good ratio for keyword diversity?

[ChrysalisSEO]

We all have primary keywords that we are optimizing for. For instance one of mine is "Video Conferencing Systems." I've read that you should have about 5-10 different keywords you should optimize for, however, would you want to create more links with your primary keyword than your other keywords or spread them out evenly and optimize for the primary keyword on in the actual content of the page?

The majority of KW Diversity/KW Ratio/Anchor Text type on-page seo tactics are not that relevant anymore.

It is important to have keywords on your landing pages, but do it as naturally as possible.

19. Diversify Your Anchor Text - Naturally

If Google’s Penguin update taught us anything, it’s that over-thinking anchor text is bound to get us in trouble.

When you link naturally and editorially to other places on the web, you naturally diversify your anchor text. The same should hold true when you link internally.

Don’t choose your anchor text to fit your keywords; choose your anchor text to fit the content around it.

Practically speaking, this means linking internally with a mix of partial match keyword and related phrases. Don’t be scared to link occasionally without good keywords in the anchor – the link can still pass relevancy signals. When it comes to linking, it’s safer to under-do it than over-do it.

Your response is interesting because I've notice anchor text on longer phrases lately rather than the keyword itself. Thank you for the response. It was very helpful.
