Ever see a page that just looks spammy? Perhaps something like:

“Bob’s cheap Seattle plumber is the best cheap Seattle plumber for all your plumbing needs. Contact a cheap Seattle plumber before it’s too late.”

Not surprisingly, a persistent myth in SEO revolves around the concept that keyword density—the number of words on a page divided by the number of instances of a given keyword—is used by the search engines for relevancy and ranking calculations.

Despite being disproved time and again, this myth has legs. Many SEO tools still feed on the concept that keyword density is an important metric. It’s not. Ignore it and use keywords intelligently and with usability in mind. The value from an extra 10 instances of your keyword on the page is far less than earning one good editorial link from a source that doesn’t think you’re a search spammer.
