To get rich in World of Warcraft you are going to have to be prepared to do some work. There's no way around it, gold isn't going to simply appear out of thin air.
Once you decide that you want to earn gold, the first thing you need to do is consciously set aside some time to farm. This will mean sacrificing some play time.
Secret Number 1 - Mining
Mining is perhaps the largest gold producer in WoW. It also offers beginners a great chance to start earning gold from as low as level 5. Once your character hits level 5, start mining every single node you can find.
You can get a bar of gold for a stack of copper on most servers. While that might not be much for a high level player, a newbie will get great use from that. Mining produce is in hot demand by Blacksmiths, Engineers, and Jewelmakers. You'll find high demand for mined metals on every server.
Secret Number 2 - Fishing
Even though it's traditionally not seen as a lucrative profession, gold can be earned rather well through fishing. If you take the time required to get your skill level up to 375, you'll soon realise this.
A lot of the more elaborate and high end cooking recipes require rare types of fish. Many players in the cooking profession are either unable or too lazy to get the fish they need. By providing these rare fish you can make some very good profits.
Secret Number 3 - Herbalism
Herbalism can be a good little money earner on any server as the demand for herbs is consistently high. Collect a few herbs and you'll be able to sell them to Alchemists for a healthy return.
Herbalism, Fishing and Mining are 3 professions that can be quite lucrative when used wisely. Mining and Herbalism are great for low level players as from level 5 onwards you'll be able to easily earn gold in fairly short time frames.
