Affiliate Marketing Resources

Affiliate Directories

Here are two sites providing lists of the affiliate directories. Some of the directories are listed on both sites, so be sure you don't submit your program to the same ones twice :)

Affiliatemarketing.co.uk
AffiliateManager.net

Affiliate Announce will submit your program for you. I have used Neil's services and recommend him highly. The time saved was well worth the nominal cost of the service.

Helpful Software
