For those of you that are not sure what keyword density is, here is the Wikipedia definition.
“Keyword density is the percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page.”
Back in the dark ages when SEO was in its infancy you could actually get high rankings in search engines like AltaVista simply by adding your keyword a hundred times at the bottom of the page. Google classes this action as spam so don’t even try it.
Depending on who you ask you may be recommended to use a keyword density of anything between 1% and 7%
To be honest you shouldn’t really worry about keyword density, if your content is well written and contains your keyword a few times this is fine. Your keyword should also be in the title tag, meta description tag and H1 tag if possible.
Kenword density is only a very small part of on page SEO so this is something you should not waste too much time on.
Lets look at our example of “ladies designer shoes” again.
The site with the number one position does not have the phrase “ladies designer shoes” anywhere on the page!! The Title tag is “Women’s Designer Shoes” I believe that Google uses LSI so it recognises that “ladies” and “women’s” are very similar.
The phrase “designer shoes” has a keyword density of 1.06% The word “shoes” has a keyword density of 2.65%
Look at the site at position 5 (and this is what I would call a spammy site. I am surprised Google is ranking it so high, this is the type of site the Pandas and the Penguins are supposed to de-rank) This site has a keyword rich domain name and the keyword density for “ladies designer shoes” is 10.64%. It is repeated 36 times on the page of 1015 words.
There are 2 sites that rank on page one with a keyword density of outside the 1%-7% recommendations. In fact the only website on page one for “ladies designer shoes” that has a keyword density of in-between 1%-7% is the site at position 8, with a keyword density of 4.88%. 8 sites on page one have a keyword density of less than 1% and one has a keyword density of over 10%
So draw your own conclusions, How Important is Keyword Density?
There are many other factors you need to consider for top rankings so don’t waste your time analysing keyword density. Just write interesting quality content that humans will want to read.
