Keyword Research
If you want your intended audience to find you on the world wide web, you must use the right keywords. Finding the right keywords is what Keyword research is all about. Professionals and amateurs alike work at figuring out which keywords and keyword phrases will help them get noticed. And then they do even more work including these keywords in natural, conversational ways so people will actually read their web pages and search engines won't penalize them for keyword stuffing or other banned practices.
Keyword research involves making lists of all the keywords people use that might take them to their site… from the common keywords to the less common keyword phrases (which, some argue, actually account for the highest sales and conversion rates since these people are more likely to be seriously looking for what you offer). Lists of keywords can be generated from brainstorming sessions or with keyword suggestion tools online.
