Alright, so I'm starting a directory site for a city, I want to cover ALL businesses within the city. I think it's a really good idea, currently, but I'm having problems with how I should handle some of the SEO. Firstly, I have about 10 tags for say, "restaurants", and about 200 restaurant listings. If I use one of the ten for each listing, will I be penalized for keyword stuffing? Also, unfortunately these posts are quite sparse, mostly just name, address, phone number, tags. I plan to do individual SEO(linkpushes, etc) for each sect (restaurants, apartments, etc), SO my question is, should I direct the backlinking to the Category page, which is quite lacking in onpage SEO, but the most obvious to have rank, or should I create a highly optimized page for the category, link and reference the actual category page multiple times, and build backlinks to that? Also, I've heard many people say to noindex your category pages. Why is this? I can PM my link to someone if they can give me some advice. Some insight would be much appreciated, thanks guys.
