I just finished reading the Beginners Guide to SEO at SEOMoz and joined as a Pro Member.  I have created a campaign for my new SEO project and feel like I have a good understanding now of on-page optimization.  I am going to start fixing title tags and on page content for our top 50 pages and start a new campaign to go after some keywords.  Our website is 360dwellings. I am struggling to determine what the best keywords are for us to target.  Right now our primary markets are Denver and San Diego, we also display listings for all of Colorado as well. We had originally gone after competitive keywords like "Denver Homes for Sale".  What I am learning is that even ranking bottom of page one for that term doesn't bring a ton of traffic. Meanwhile, we rank well for a lot of niche content like "5280 best neighborhoods" "Denver Lofts for Sale" and "Denver Neighborhood Map". My questions is do we completely abandon going after big keywords like 'Denver CO Homes for Sale", and 'Denver Real Estate" and go as far as removing them from title tags?  We have pages for every Denver neighborhood like Park Hill and the Highlands, but there is no search data for these searches in Google Keywords.  My gut says that if each of those pages ranked for terms like "Denver Highlands Neighborhood Homes for Sale" that it would bring good targeted traffic.  Does anyone know of search terms for Real Estate that are low competition but have some search volume? Thanks!
