What is The Perfect Keyword Density? –
The short answer to this is – no.
There is no one-size-fits-all keyword density, no optimal percentage guaranteed to rank any page at number 1. However, I do know you can keyword stuff a page and trip a spam filter.
Most web optimisation professionals agree there is no ideal percent of keywords in text to get a page to number 1 in Google. Search engines are not that easy to fool, although the key to success in many fields doing simple things well (or, at least, better than the competition).
I write natural page copy where possible always focused on the key terms – I never calculate density to identify the best % – there are way too many other things to work on. I have looked into this. If it looks natural, it’s ok with me.
I aim to include related terms, long-tail variants and synonyms in Primary Content – at least ONCE, as that is all some pages need.
Optimal keyword density is a myth, although there are many who would argue otherwise.
