Keyword Density Help

If you are talking about longer tailed keywords then they would naturally appear lesser number of times in the body. That's the whole purpose of them being long tailed.

I don't know about others, but I would simply go natural about it, have it appear only a few number of times (could be once in around 100 words for "shorter" long tails and once in 200 words in "longer" long tails, as a random example) and do my off page stuff. Plus, I would want such pages to rank for multiple long tails - I would target multiple related long tails, and put each long tail at the above frequency.

For mainstream keywords, the keyword should appear much more frequently.

The concepts of Term Frequency and Inverted Document Frequency are the first step building blocks for any search engine (and they would use these concepts in their own way) since hypertext based information mining is founded on those concepts. So I believe the above looks natural enough while remaining within the radars.

The theory that I always use is to write for the reader and not the search engines. I do not follow a density that every article must have. You want to make sure that you are getting your keywords in the article, but at the same time do not want to sound spammy.

General rule of thumb that I use is if you feel that you need to force your keywords into your article, then you are overdoing it (particularly for long tail keywords)

Is that true that you have many keywords, this will be easier for your website to be in top?

Hi, you can create sub points and insert your keywords over there, 2-3% keyword density is good for articles.

Anyone know of a good keyword denisty tool? I always just calculate it in my head.
Thanks!

See, there is no hard and fast rule of keyword density. Though, a few search engines are very strict about it.

What I believe is keyword occurrence should be organic. If your content demands more keyword placement, insert them.

There is a thin line between inserting and stuffing. Unnecessary placement is stuffing and it is black hat and may lead to penalty.
