Social marketing is all the Web2.0 stuff that has an element of word of mouth marketing to it and can be a great viral way to get free traffic.
Join social networks that cater to single men. Use StumbleUpon, Myspace and others and make friends in your niche to drive traffic to your site. Start a blog and add it to mybloglog and blogcatalog, then join related communities that may have an interest in your niche.
Start a Squidoo lens and or a Hubpage to get your site started as your articles should get higher search engine rankings on those sites. Build some content there that links to your new sites or even just do a keyword rich overview of some of your articles and link to your site to read the rest.
Search the forum for any of the words I've mentioned if you aren't sure what they are or how to use them. We have a new
Web 2.0 Marketing - Social Networking Forum that covers some of this.
