You only need to understand one simple fact if you want to know how to make wow gold and that is which items you should farm or gather to sell at the Auction House. There are a few criteria that items should meet if you are gong to make fast gold:

1. Other players want and need that item. There are a many items in WoW that have their name in white text (indicates that the item is useful to players in some way) but will not sell well because players do not really need them or because they are not needed to make crafted items that are popular. Ingredients for popular equipment, gems, glyphs and enchants will always sell for a good price and so will some blue and purple items.

2. Players should want to buy lots of the item at once. Now we discussed blue and purple gear above. If you just come across one of these as you quest or do instances, thats great; go ahead and sell it. But do not bother trying to farm these deliberately. The stuff that will really make gold in WoW for your items that other players will buy in stacks. Examples are items that people can use to level their professions or to improve their faction. These are great for building up your WoW wealth.

3. It should be quick and simple for you to get hold of. Items that you get from professions such as mining and skinning are the simplest ones to get. Gathering is easier than farming mobs (but there are lots of the type of mob that drops it, this can be an effective way to make fast gold too. Gathering professions are a great way to make wow gold, more than ones where you craft items. such as blacksmithing or engineering.
