I was wondering how often I should mention a keyword on a simple product page or in a blog article to push up the search engine rankings for that particular keyword.
Is a key word density of 10% acceptable for this page?
What if each single page has a 10% keyword density?
I dont understand how people can rank for keywords with a density of 1% only on one page and 0% on all other pages of their website *confused*
10% is way too high and would make your article look ridiculous to any readers and spammy as hell to google. Keyword stuffing used to work several years ago and people would even use white text on a white background to hide them from their readers while the spiders still recognized them for use as a ranking factor. Those days are long gone though.
1%-3% seems to be the going trend but there really seems to be no magic number. LSI keywords sprinkled throughout your content seems to be a discerning factor in ranking a page for your targeted keyword. Google LSI keywords... latent symatic indexing... and read up to get a better understanding.
As for the 1% density on one page and 0% density on the other pages... Well LSI keywords are likely a factor there as well. Basically its just related keywords that should be mentioned and covered on a site that is providing good, informative content on a particular subject.
Just a vague example would be if your keyword was "Dog".... Well you mention "Dog" 1%-3% in your article but you also mention "German Shepard", "Pit Bull", "Chihuahua", and "Collie" in that article... Well those are all different types of dogs, hence a related or LSI keyword. Google detects your article is about dogs.
Then you write an article strictly focusing on "Collie"... dont even mention the word dog in the article but interlink it back to your main "DOG" article. Then do the same with the other breeds. Even though those articles dont mention "dog" Google knows they are related and will give a little juice to your main article.
So read up on LSI keywords and site interlinking to get a better understanding... I would also suggest you read about silo sites as this will give you a better understanding on using internal link juice flow on your site to increase rankings.
Hope it helps and I just rushed this post cause I got shit to do... maybe someone else could chime in with some tips.
Good Luck!
