Bit like coming on here and asking advice on finding a wife!!! What works for you doesn't mean it will work for me!!.

There's only one way and that is to learn what ajustments do what.

Most important piece of kit you will need is pen and paper so you can note ajustments down and if you don't like it go back to where you started and it's easy to get lost if you haven't made notes.

Under normal circumstances you'll be looking at around 30mm of sag on the shock,rather than me explain just google it.

But I have a bike that doesn't have any at all and I know other guys who don't on theirs either.

Where it will get even more complex your shock has a combined compression and rebound the ajuster at the bottom of the shock,you may not like the speed of which the shock compress's but chase that setting too much and it will effect the rebound hence why you pay top dollar to have a shock that has separate ajustments.

Bottom line make big ajustments,don't go 1 or 2 clicks make it 5 or 6 so you can feel the difference and what the shock is doing and the same when you ajust the preload ajuster on the shock and as you get closer to what you like go into smaller ajustments.

It's only complicated if you think it is!!! It's just a learning process that so few bother with and yet they should because it makes for a much better bike.
