How to get good traffic for a new Website

I have a Website with Premiere Websites, templates and Domains for sale at www.webauctionsdaily.com. How do I make sure that Search engines index my Website: www.webauctionsdaily.com so I can attract serious buyers. The Website is an Ebay partner network website with discounted selection of new and used websites at low prices just like SitePoint Marketplace. How do I make sure that I get good traffic like SitePoint Marketplace, etc. for a new Website?
