Smart subscription site professionals know that a good business Model includes diversified revenue streams. One of the most profitable revenue streams for paid content sites can be live events.However, event programming and marketing is time-intensive. Some sites may not have the staff, while other may need to make sure their audience is going to buy.In this week’s Case Study on Subscription Site Insider, Contact Any Celebrity Founder Jordan McAuley gave us a great tip for testing audience reception to offline events: affiliate marketing.Contact Any Celebrity routinely sends email blasts to subscribers for offline events hosted by other sites and companies. Because subscribers would want to know about these events anyway, the emails are seen as more informative than intrusive. And the site is able to receive an affiliate commission for any subscribers that signs up for an event.This is a smart way for a subscription or membership site to get paid for doing its own market research. The next step, of course, is to start hosting virtual meetings (e.g., Webinars, teleconferences) and offline events of your own!
