Proper method of chain adjusting

Pretty simple question but what are the tricks to getting the chain tension just right? Too loose chain rubs on chain slide, too tight and chain makes some funky noises. Who has the easiest method?

Squash down your suspension flat by using a ratchet strap across the seat until the swingarm is paralell to the ground then adjust the chain just shy of tight, that sould do it! Viola you're done! Remember to check the sitting on the stand tension right after you're done removing the strap. This is your chain tension, unique to you bike. Good day.
