1.first your gonna wanna make a bank alt.A bank alt is a lvl 1 character that stays in a main city (ex:Stormwind,Undercity,etc..)and when your playing on your main or any other toons when you pick up any green,blue,epic purple,cloths,ores,or herbs your gonna wanna send it straight to your bank alt. This will save you loads of time instead if wasting time running to a major city and listing all of these auctions.
2. Get 2 gathering professions (ex:mining,herbalism,skinning) when you get to lvl 5. Theseprofessions you can make lots and lots of gold with. First you gather the herbs the leather and the ores and smelt the ores if you have mining then send them to your bank alt to list the on the AH(auction house).The simple copper bars sell for 15 gold a stack on my server!! Thats just easy gold.
3.Go to http://www.curse.com/ and download the addon auctioneer. This is the best tool to make gold on wow.This addon scans the AH and list the prices of how much items go for. A more detailed video about this addon can be found by a wow video maker named Ryutarou http://www.youtube.com/watch?v=KrhLjWpOszw&feature=related
4. Just lvl and have fun. when your lvling just follow these steps and im sure you will make gold in no time.
well tell me in the comments how much this has helped you make gold on world of warcraft.
