Keywords are just phrases that you want or perhaps just happen to rank high in the search engines. Back in 1999 adding keywords and a description for your meta tags or just making articles on your desired keywords.

A lot of people took advantage of keywords by adding them in artificially into there pages improving there SEO (search engine optimization) but I'm sure you have heard already search engines are becoming increasingly cleverer. And they are killing SEO and it is no longer effective.
