Repeating Keywords

Another common mistake that people make is to endlessly repeat their target keywords in the body of their pages and in their Meta Keywords tags. Because so many people have used this tactic in the past (and continue to use it), the search engines keep a sharp lookout for this, and may penalize a site which repeats keywords in this fashion. Sure, you do need to repeat the keywords a number of times. But, the way you place the keywords in your pages needs to make grammatical sense. Simply repeating the keywords endlessly no longer works. Furthermore, a particular keyword should ideally not be present more than thrice in your Meta Keywords tag.
