Wow gold: Technique makes more wow gold.

Typically players farm for wow gold using a couple of different techniques. What you need to understand is that both techniques require time and patience as you go through the game slaughtering various humanoid creatures. Although it may seem a bit monotonous, humanoid creeps drop gold and cloth that you can collect. The benefit of collecting the cloth is that it can be a valuable commodity to sell at the Auction House for a hefty price.

The other technique is to slaughter or follow non humanoid creeps as they can be skinned for leather. This is also a profitable item that you can sell at the Auction House. Regardless of the method you pursue, just know that it will take time to build up your wow gold these ways.
Another option to build up your wow gold is to find what items are selling hot. You can then purchase these items and turn around and sell them for far the future. This can be risky as you do not know if the items will continue to be popular, but it can be a quick way to attain wow gold.
The last method to build up wow gold, and by far the riskiest, is to purchase them over the internet. Amazingly, there are players and web sites that will sell gold in exchange for actual money. While this is the fastest way to get gold, it can lead to your account being suspended for some time if you get caught. It can even lead to complete termination of your account depending on the circumstances. Ultimately, you need to decide what you are willing to do to build up your wow gold collection.
