The right profession makes all the difference. Choosing the right farm locations and using your skills is important too. For example, if you're a skinner, you will want to play in areas where you can skin the monsters that you kill. If you're a tailor, you'll want to play in areas where cloth is dropped off by humanoids so you can make clothing.

Visit the local vendors. Look carefully through their items. On the last page of items for sale, they will often list a rare or unique item in limited quantities. You'll see bags, recipes, clothing patterns or potion items. Buy these rare items and sell them in the WoW auction house. The earning potential here is very great.

Get off the main roads. Focus on destroying the creatures you find off in the wild. They will leave different amounts of WoW cash and loot that you can sell in the WoW auction house. If you focus on this rather than adventures and quests you will see a definite growth in your gold.
