I’m trying to find spider spawners to gain experience on an SMP server. I’ve seen other players that have found 4 spawners near each other. Is there a trick to finding one or more?
I’m assuming you mean cave spider spawners. The best way to find them is to search abandoned mine shafts. The abandoned mine shafts are generally tunnels 3 blocks high and 3 blocks wide and have wood blocks and fences creating frames around tunnel. They have minecart tracks, cobwebs and random chests placed in them.

Most notably is that you will find areas filled with cobwebs. This area has cave spider spawners. Sometimes you’ll find spawners close together but finding 4 in the same area is pretty rare.
