Though it is really a good approach of using synonym keywords instead of keyword stuffing but it appears a bit confusing about how to calculate actual keyword density of keywords used in the body. It is said that keyword density is important in terms of setting the relevancy of the page with the search terms then the question arise is how can we calculate the weight of the page in terms of keyword density when using synonym as keywords. For example – If I am using keyword “Yoga for pregnancy†5 times per 100 words then it stands as 5% but what if I am using the synonyms “Yoga for pregnancy†3 times and “Prenatal yoga†2 times. Does it makes a complete keyword density of 5% for prenatal yoga and yoga for pregnancy as well or it individually stands as 3% and 2% for their respective density?
I'd be interested in this answer too, although I suspect that you'd loose the 5% density for "pregnancy" and "prenatal" ... but how about "Yoga"?
If you use a keyword phrase 5 times in 100 words, chances are the article will read like crap. If you worry about keyword density, your article will probably read like crap) Putting the keyword in the title, opening paragraph toward the end and in your resource box is normally all you need. Then write good content and the rest will take care of itself. You will find a difference of opinion with regards to keyword density for articles. When I first started I found that a lot of my articles that had roughly 5% or a little more were often rejected. The 3% range articles were almost always published the first time I submitted them. And I will have to admit the 3% articles read much better than the 5%. Just my experience. With regards to synonyms (LSI), nobody really knows how google treats it. We do know that it is probably one way the Google detects keyword stuffing. And it is probably part of the algorithm used to determine page relevancy. The bottom line is that there is no need to be concerned about keyword density unless you overdo it.) If your content is "on topic" and reads well, then you will have pleased the Google gods and readers. Just my 2 cents..
as great at zeeks advice is, the sad thing is there will be always be a point that google will value one site over another because it has better keyword density etc, so imo it's something unfortunately worth worrying about, else you'll be leaving a huge gap for your competition to easily beat you. the quesiton asked is a very valid one that i'm often concerend about whether i go for keywords or not, as now i know about it i'm always concerend i'll go over. i would imagine google class each phrase seperatly but will wait for someone experience to answer this.
