Novice optimizers often make the mistake of not taking advantage of keyword variations, synonyms, and family keywords in optimization practice. Though may achieve high keyword density by repeating the same keyword throughout your article, it is also worthwhile to replace a few of the original keywords with variations. It is a good idea to do keyword research to find out which keywords are popular in search engines, but remember that not all internet users think alike. Check out a website with keyword variations for keyword derivatives or keyword deviation for more terms that may be used by internet searchers. Varying your keywords will seem more natural; your website will appeal to both readers and search engines.
