There are tried and true best practices for subscription business models, but every once in a while, a company turns the model on its head.That’s the case with IndiaProperty.com, a Web portal that sells listings for real estate properties in India. While most real estate listing sites turn a nice profit by selling listing space to sellers and construction companies, IndiaProperty has turned “advertisers” into “subscribers” by selling subscription packages for bulk listings.This is a subtle difference, but one that helps condition a lucrative audience to the idea of buying advertising space on a subscription basis, therefore affording some predictability to ad sales. It’s even more revolutionary if traditional ad sales departments adopted it. Imagine if news organizations and consumer magazines could rely on predictable advertising revenue?And more surprisingly, IndiaProperty has even been able to put some of their advertising subscribers on auto-renew. That’s because India is currently experiencing a real estate boom, and sellers and construction companies are often selling out apartment units before buildings are even completed.Subscription sites in less growth-oriented industries might want to hold off on the auto-renew. But with CEO Ganesh Vasudevan — a veteran of the online dating world — at the helm, IndiaProperty is full of good ideas for monetizing audiences, including a cross-sell product for ex-pat Indians on the consumer side.For the in-depth report, join Subscription Site Insider and read the Members-Only Case Study on IndiaProperty today!
