How To Calculate Keyword Density Properly

I stumbled upon a strange problem but I am sure others have experienced the same.

Lets say I have a "Keyword Phrase" (two words). My copy consists of 366 words and the "Keyword Phrase" is mentioned six times throughout the text. When using a certain keyword density tool it says I have 6.55% (it thinks I have repeated my phrase 12 times)

When using my logics (which is not the best thing to do) I think that my keyword density for the "Keyword Phrase" is 3.27%

I would be very grateful if you share your methods of keyword density calculation. Thanks!

i'm guessing it a calculates the occurrence of one or the other keyword rather than both as a phrase, since 3.27 is approximately half of 6.55.

try an experiment wher one keyword in the phrase doesn't show at all in the text and see if you get a result of3.27 instead of 6.55.

There are so many methods of calculating keyword density, unless the author of the tool explicitly tells you his/her method, you'll likely not know for sure.

Some will throw out all of the non-indexed words like 'of', 'the', 'and', etc. before calculating the keyword density. Different tools may throw out different words before making the calculation. Others may not throw out any words at all before calculating it.

Keyword density is overrated IMO. There is no magic #. I've seen pages rank on page 1 of the SERPs w/ 25% keyword density, others with 0.25% keyword density.

Write good relevent content... that flows as it would in natural conversation and you will likely rank just fine.
