I have a website and have installed WordPress - www.gamerzville.com to promote products. I went in all guns blazing when buying the domain and didn't do proper keyword research for the products I'd like to sell, 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 (Trying to sell the products I am promoting). Are there any other options here or am I completley screwed and ruined it for myself? Any advice would be appreciated.
I think if your categories are action, adventure, shooter, simulation then they are too broad, but if you add action games, or action video games then it would be more closely related to your site theme.
Exactly. Try longer tail KW's, but only after proper keyword research. don't just make them up. See what your competitors are using, maybe even use a keyword research tool
Take a look at what keywords your competitors are ranking for, do a study of their backlink profile and, if not too competitive, replicate (as far as possible). Studying competing sites will give you a better idea of what phrases bring traffic than using tools like Adwords, etc.
