Here is another good way to make WOW gold, pick right professions as your secondary professions.

While your two primary professions should be gathering, make sure you take up Cooking, Fishing and First Aid. You can have all three of these secondary professions in addition to your two primary ones. Take your time on these professions in World of Warcraft, leveling them. You don't have to invest too much time and money into it, but when they get to a high level, they will make profit of WOW Money for you, especially with cooking and fishing.

Wow gold making process can be very easy. Go to the auction house, and buy raw Golden Darter or Furious Crawdad. Cook it up and list for a profit. Remember patch 2.3 introduces new Cooking Daily Quests, so if you don't have cooking leveled, you can't benefit from the easy World of Warcraft money of these dailies.
