from 1-5% very important to keep it in that range .... keywords are the only way people could reach your site destination....
the time spent optimizing on page density would be better spend building links, in case you havn't noticed, this game is all about link juice, no one knows optimum density except for google and it constantly changes, better to invest in link building IMO
I'm not that bothered for my sites to be honest. Just write naturally, keyword stuffing just won't occur and you'll touch all LSI bases at the same time. Andy
I think 2% to 4% is perfect keyword density . I Know About this Percentage Because Ezinearticles is Also allow just 1% to 4 % keyword density in each article. So I Think 1% To 4 % Keyword Density is perfect in SEO
I usually keep my keyword density between 2-6% .Too low or too high is not conducive to the article included.
Keyword density can be seen in the percentage of times a keyword appears on a page when compared to the total number of words in the main points page.One choose keywords to find the keywords that are a good number of searches each month, but there is not much competition for them.
kw density if you have the keyword 4-5 times in the page it should be plenty - backlinks are more important anyway.
As others have stated some where between 3-5% is good enough. Too low and you might have trouble ranking for that keyword, too high and you may get a visit from a big bad panda one day or another.
according to me keyword density according to keywords 3 words keyword density - 2 to 3% 2 words keyword density - 3 to 5% 1 words keyword density - 5 to 8% Now you reply me right or wrong keyword density please
