I've only been doing it for a couple months. Still need some time before people hopefully convert from the free tier. Good traffic but ROI is not great yet. But with SaaS, a few good conversions can pay for everything pretty quickly so I'm going to stick it out for a bit.
There's a saying in advertising that someone has to see a thing 8 times from different sources before they buy it. I don't know how scientifically accurate it is, but it reflects my behavior.
