I have a website and have installed WordPress to help promote products. I went in all guns blazing when buying the domain and didn't do proper keyword research, so my only option is to have a gaming review website. Here is where I'm struggling and trying to process the whole keyword thing. I've created Categories such as Action, Adventure, Shooter, Simulation etc. People are telling me to create keyword rich categories, but how can I do that if I am promoting more that 1 product that belong to the same category? How would I get my website ranked in google, seeing as it's a review website. Any advice would be appreciated.
