We just launched our site 6-8 weeks ago. We use the freemium model to offer two services: gigs & jobs. One service is free with a premium upgrade available while the other service is always a pay model with a premium upgrade available as well. We are trying to boost our pay side and are considering running the month of January free to build some trials and hopefully long-term users.
What does everyone think about this approach? Our thinking is that as long as customers know up front this is a pay service that is being offered free for a limited time that, if happy with their results, they won't mind paying going forward.
In the meantime we are running a PR campaign and have started our "inbound marketing" campaign.
