Here are two resources for online marketing.

The Linknet Power Marketing Forum has many useful marketing, promotional and advertising services as well as free downloads every week. This is a membership only site. Linknet Self Serve Blogging is included. This allows you to post to any of about 25 different blogs (the number is growing.) Also article writing and distribution resources, press release resources, email marketing resources, and much more.

Squidoo is a free service that allows you to post any number of “lenses” - pages about yourself, your website, your products, whatever. You can join groups where other members can see your lenses. Build inbound links to your websites. Here’s my Self Serve Blogging lense.
