Before advertising such site, determine what kind of relevance your site offers over your competition.
IMO marketing your website start with your content. Providing useful and relevant content in your niche is very crucial. Here are my top 5 picks:
1.
Great content - be it information, service, products... providing relevance and usefulness gives you higher chances of making a visitor into a customer
2.
Forum and blog posting on relevant niche - you participate constructively and learn new things while promoting your site via signature.
3.
Pay-Per-Click - done properly, best at getting target traffic faster on a direct marketing approach to your potential clients.
4.
Targeted Link backs - another premium way of getting the right traffic.
5.
Article marketing - useful and relevant articles to your niche is a nice way of link baiting.
Hope that helps
