To get an article indexed at the top search results of major search engines, the importance of the number of times a specific keyword is used is often just as important as the quality and popularity of the keyword itself. The density often varies from article to article, but it should be present to a certain degree to make it seem to be important.
Surrounding an article around a good keyword is what makes the presence of the keyword felt. A keyword should principally be used at the topic heading. Repeating the keyword in the body should be just optimum which is around fifteen to twenty percent of the entire article to the maximum. Wavering from this percentage on both directions can possibly have unwanted effects. The keyword should be cleverly used so that the indexing faces no problems, yet the reader does not get bored.
A very high density of keywords causes the effect of the article on the reader to suffer and turn him off. Therefore, he just ignores it completely. You certainly do not want that to happen. So do your research for the keyword diligently and check the number of times it appears in the article before publishing it online.
