What has been your most surprisingly lucrative marketing channel or activity?

Our best channel is organice traffic and the second is PPC. But two suprising channels that continuous to send qualified leads is Quora and Pinterest. Pinterest is probably not for everybody, but I'm sure most buisness can benefit from Quora.

For our company, FlippedNormals, our YouTube channel has been one of the most incredible marketing channels. It's allowed us to engage directly with our audience and potential customers. It's definitely not a viable marketing strategy for everyone. But we're in the creative sphere and it helps us create a lot of free content for our audience. And as our reach grows there, so does the potential for more customers. We've been at it consistently for a few years and now we output 1 video every week. It used to be 2 a week, but we don't have the time anymore.
