Craigslist misses a huge area where I live. I was considering starting a free local classified ads site and monetizing it with Ad placement here and there. Two questions:

- What is the best way to get people from the local area to come and post? Facebook?
- How can you optimize a local classifieds site for good SEO rankings? For example, what keywords would be best when it encompasses 6 or 7 local cities?

Thanks for the advice.
