This is my first post on here as I am mainly on Stackoverflow and Serverfault. I have been programming for at least 10 years now, have made hundreds of websites but I have just recently started getting into Design and the SEO side of sites, sad that I have been overlooking these for so many years.

I have pretty good knowledge from all my years of SEO but I have never really looked into it until now.

My question, I would like to build a site that targets many different key words for the search engines, for an example. Let's say I built a site about Outdoor activities called outdoorreview.com and I planned on having many sections
hunting fishing Hiking camping cycling climbing etc...

For best Search Engine results, how could I get the most search engine traffic to all these ares?

Also how should I structure the way to get to them, outdoorreview.com/Hiking/ or hiking.outdoorreview.com ?
