Keyword Density

Another important concept is keyword density. When a user searches for a keyword phrase, the search engine looks at all the pages that contain the phrase and checks the density — the ratio of the search phrase to the total number of words in the page.

For instance, suppose that you search for rodent racing and the search engine finds a page that contains 400 words, with the phrase rodent racing appearing 10 times — that’s a total of 20 words. Because 20 is 5 percent of 400, the keyword density is 5 percent.

Keyword density is important, but you can overdo it. If the search engine finds that the search phrase makes up 50 percent of the words in the page, it may decide that the page was created purely to grab the search engine’s attention for that phrase and then ignore it. On the other hand, if the density is too low, you risk having the search engines regard other pages as more relevant for the search.

You can get hung up on keyword density, and some people use special tools to check the density on every page. This can be very time consuming, especially for large sites. You’re probably better off eyeballing the density in most cases. If the phrase for which you’re optimizing appears an awful lot, you’ve overdone it. If the text sounds clumsy because of the repetition, you’ve overdone it.
