Q: Do you know where I can find information on the size of the industry and general information, or a positive article on the state of affiliate marketing?
A: There are a number of resources where you can find information and statistics on affiliate marketing. MarketingSherpa and Internet Retailer routinely publish coverage of the industry.
Also, you can read case studies, editorials and articles on affiliate marketing at ReveNews.
Additionally, I collect and publish statistics on affiliate marketing once a year. The report is called AffStat.
