SM tends to be a site where teasing in free chat leads to fewer folks tipping or going private. If they're already getting a show for free, they're much less likely to pay.
There are also an infuriating number of members who think that if you're doing ANYTHING, you're "too busy" for a show.... Even though that's the whole reason you're broadcasting.
On the other hand, I've seen people get shows fast teasing, making out, even sucking dick *just* out of frame, so that can work as well.
Different approaches work for different people. Don't get discouraged, just experiment with different approaches until you find the one that works.
Another thing to play around with is time slot. I can get on at a certain time, and have nothing but freeloaders for my first hour, log off, get back on two hours later, and be busy then. So try out a couple different times of day, too, if you can.
