Then get out of the categories and look at the web sites. You will get the same result. Just try and get as high as you can on each. First, do not repeat keywords. That used to work, but not anymore.
Most search engines disregard that now.
Secondly, list your keywords in order of importance. That is the number one thing that search engines look at when ranking your site. So if your site is about comic book collecting, then name your site 'Matt's Comic Collecting Site' or something. Obviously if your name is Tom then you don't want to use Matt, etc. For example, if you have one page dedicated to the comic Poison Elves and another with Spider-Man, then set up keyword tags on each page specific to each comic book.
