Does it matter? is it worth doing?
A few years ago I would have said yes but now im not sure. I got a site to top of Google about a year ago now and it is full of keywords which tried to space 1:20 and 1:30. A few result lower another one of my sites is there but i have to admit I have not put as much effort in to it and nowhere near as many keywords.
So why? Personally I believe that word frequency doesn’t matter, as long as you target your keywords to each page, the frequency of the word does not matter.
Or am I wrong?
