I think that the reason that the free trial retargeting works is because there's no friction. But for a service-based business, it ends up becoming come get a demo. And so I would try and think about how to limit the friction as much as possible. There's a fine line here between offering a free ad analysis and making it a free discovery for your to sell. Those are some of the ideas that are floating at the top of my mind.
