There are so many words on the page to begin with and the phrase is a bit long. and honestly working that phrase into the text is not that natural in anything close to what we normally would think of as decent kw density.
Just to get to 1% I have to put it in the page 16 times, and that to me is unnatural. At present its .5% kw density and even that I feel its a bit awkward in the flow of the page.
is .5% to 1% kw density acceptable. ?
I do notice that my SEO tool I am using, (clickbump SEO) Does not seem to like .4 or .5% it doesnt light up green , says kw density is "low"
