Here ya go:
Signup for Squidoo, Blogger, Youtube, Wordpress, any other similar social site(s) where you can add your own links.
Next, modify each account, with a link to your main site, and the key is to link to all other social directories/websites you have accounts with...
Main Site: YourSite.com
So, for each of these profiles, add a link to each other profile, and your main site. Basically, you need to create cross links between each profile, and thus create a "web" of links/crosslinks that all link together, but ultimately link back to your main/authority website.
Next, once you have this "web of links" setup, now ping each individual site(s), that link to all your other sites/profiles using a service like:
Blog and Ping Tool - Use Pingler.com to Drive Traffic your Blogs and Websites
Submit all of your "profile" sites that point to your main domain, as well as submit your main domain to be "pinged"
Final step, once you have some authority/link juice going, then submit to the social bookmarking directories, like Digg.com etc...
Now you have instant backlinks, as well as a "web" of links that can grow to give you more authority status/link love.
(Make sure to use Anchor text links that are relevant to your keywords)
Let me know of your own "tricks" to add to these techniques...
