For wow you can check out some world of warcraft gold making guides to make your gold making easier.
First the easiest way to make gold in World of Warcraft is to have two gathering professions. Such as mining and skinning. You can use your mini map to find rocks to mine. Skinning can be done on most any animal you will come in contact with, allowing you to quest at the same time. This is a profession where you go along in your journey and collect things.
Questing. Start collecting quests like they are candy. Once you have a good handful of them, go and complete them. You generally will end up killing a bunch of monsters and get coin and item drops as well as the quest reward at the end. Serious money can be made here.
Grinding is one thing, but questing is another. When you complete quests, you get gold. The higher your level, the more gold you get. While you quest, you will also get the occasional rare drop item and be able to loot your enemy for items and gold. These rare drops and regular items can be sold for a quick buck if you don't need them.
During the lower level times, collect everything and resell it. This will quickly add up your money.
Check out what is selling at the auction house for good money. Find some items that are selling hot and try to get them yourself to sell.
Sometimes it is necessary to spend money to make money. If you max out your skill in your crafting profession, you can craft items for good money on the AH. You will spend less time gathering, more time making, and make more money than you ever had before. If you are part of a guild that frequents raids or can at least get some high end recipes crafting will make you more gold per item then gathering ever could.
