Make sure that your calling area allows you to see the critters yet gives you some cover. Walk into the wind to the stand setup, then turn and sit with the wind blowing into your back. The critters will circle around and approach from down wind. I sit an open bottle of skunk essence a couple of feet down wind. DON'T kick the bottle over!! Been there, done that!! I seldom stay at a stand more than 12-15 minutes unless there are bobcats in the area, then 30-40 minutes. If a critter is shot quickly, keep calling as more than one is likely to come in. Howling in an area about 1 1/2 hours before daybreak will reveal where the yotes are working, then return and set up where you got a response and call where your sure to have a yote in hearing of the call.
