Linking on a Dime

Patrick Gavin:
I think a good part of his presentation came from his link building guide.

link value is based upon:

• direct traffic

• boost in rankings
• brand lift

Getting links from pages that link out to shady sites can mess up your link profile.

He also went through many ideas about evaluating the value of a link (much of which is covered in his free online guide).

Todd Malicoat:
He placed his presentation online here. Emphasized creating natural link patterns and using creativity in link building.

Martinibuster:
Building and leverging your social currency is a huge way to build links when you are first starting out.

Emphasized mixing variety of link building mechanisms, not relying to heavily on any one type of link (reciprocal, directory, paid ads, etc).

Buying old sites is a great way to build cheap link popularity and authority. Searching for things like "temporarily down for maintenance" can help you locate underperforming sites. I also have seen some good ones by searching DMOZ and the like, of course if you do that you will want to try to get them before they expire.

MartiniBuster also tries to keep his link profile away from heavy SEO clusters, like high PageRank low quality link farms that pose as directories.
