Keyword density is the percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page. In the context of search engine optimization, keyword density can be used to determine whether a web page is relevant to a specified keyword or keyword phrase.

Despite what many SEO Tools would indicate, the short answer to this is, in my experience, there is no IDEAL %, and the video above, published many years later after I first collected the opinions in this article, would go to confirm many of the opinions on this page.

How to Calculate Keyword Density?

There is, of course, a FORMULA to work out the local keyword density of any page. Actually – there are some different variations out there on the web:

• Density = ( Nkr / ( Tkn -( Nkr x ( Nwp-1 ) ) ) ) x 100
• Density = your keyword density
• Nkr = how many times you repeated a specific key-phrase
• Nwp = number of words in your key-phrase
• Tkn = total words in the analysed text

The keyword density score for a page is essentially calculated looking at how many times a specific key-phrase is repeated in a document, the number of words in that key-phrase and the total number of words in the analysed text.

Its natural to think its then important to try and identify that ’SWEET SPOT’ to achieve high rankings in Google. The question is – what is the optimal keyword density? is it 3% or 0.3% or 33% ??
