tip 1. dont make snares and cymbals too loud
tip 2. roll off the bass freq around 30hz
tip 3. roll off the highs around 16khz
tip 4. use the best outboard eq's and compressors for mastering you can afford, you have to have a very trained ear for mastering. if you've only been into making music for a short time, pay someone else to do it
if you cant afford outboard mastering gear, you can use iZotope Ozone, T-racks or piece together your fav plugins.
hope to help
