There's no getting around it. Keyword research is a vitally important aspect of your search engine optimization campaign. If your site is targeting the wrong keywords, the search engines and your customers may never find you, resulting in lost dollars and meaningless rankings. By targeting the wrong keywords, you not only put valuable advertising dollars at risk, you are also throwing away all the time and energy you put into getting your site to rank for those terms to begin with. If you want to stay competitive, you can't afford to do that.
The keyword research process can be broken down into the following phases:
Phase 0 - Demolishing Misconceptions
Phase 1 – Creating the list and checking it twice
Phase 2 – Befriending the keyword research tool
Phase 3 – Finalizing your list
Phase 4 – Plan your Attack
Phase 5 - Rinse, Wash Repeat
