just ward where wards need to be the most so you dont get surprised
There's a lot that goes into proper ward usages but we can start with some basics that you should keep in mind.
1.) What champion is the enemy jungler (aggressive/passive/power farmer)
2.) How aggressive is your champion (early jungler/late game/level 6 ganker?)
3.) What route is the enemy junger doing vs your route?
4.) Do you have a weaker laner that needs protection/lacks escapes that will most likely get ganked?
5.) Can you contest scuttle?
6.) Are your laners buying pink wards?
Just answering a couple of those will help you determine where to best place them. Whether that's to defend your camps, your laners, the entrances to your jungle, the river or even in the enemy jungle.
In my experience Wards are rarely used to create ambushes ... although its nice when you pull it off. The main thoughts when placing a ward are well summarized above by Kaioko and you generally want to use them for informational / warning purposes. Another thing worth considering ... not just where to ward but when. If you're bot lane and you just saw the enemy jungler on the topside of the map - you might consider holding on to your ward a little longer (as long as you can see their mid in lane). If you drop in the river now it will run out before the enemy jungle paths down to bot anyway.
