Seems people are beginning to learn enough about RSS advertising to share lessons learned and set forth best practices.
- Lessons from the Cutting Edge: RSS Advertising — Interview with Feedburner’s Dick Costolo
- Best Practices for RSS Advertising :: Pheedo.
- Google: Best Practices for AdSense for Feeds
- Yahoo! Publisher Guide to RSS (perhaps ad best practices are forthcoming?) [via SEW blog]
If anyone else knows of any such documents, please feel free to pass ’em along and I’ll aggregate here. Thanks in advance!
