Lets say the keyword im trying to rank for is "restaurant boston". When doing a analyze on my site with SEO books keyword density analyze tool (or do you recommend some other tool?) it looks like this:
boston 17 words, density: 3.91%
restaurant 13 words, density: 2,99%
but under 2 word phrases it says:
restaurant boston 0,92%
So what is my real keyword density according to Google?
