Getting a good Auction House addon at a World of Warcraft mod or addon site is one thing you can do. You must pay more attention to all the median prices on various items. You can buy some of the cheapest and then resell them all at the median price. Other sellers like to think that they're doing well by undercutting, but all they're doing is enabling others to buy and profit from their items.
In order to keep an eye on the average prices, you should check back every single day. People often try to mess the system up by setting their prices way too high. If someone tries to sell a stack of linen cloth for 10 gold, that's obviously going to mess the median price up. As a result, you need to carefully check back to look for trends or changes every day.
Remember that general items and weapons are always in demand in wow gold . Unless you need them for your professions, you can sell all the gear, weapons, cloth and herbs you come across. This is because general items are needed by every player. You can get away with selling at an average or an above average price on items, weapons, and gear that are in high demand.
You should make certain that you learn how to profit from your profession. In earlier levels, you should stick with gathering professions. That way, you can earn tons of gold quickly. Wait until you're at a high level before switching to a more advanced profession. You really won't need epic armor and weapons until you're at a higher level anyway.
And also you need to get yourself a good wow gold guide, providing gold-making assistance. For example, Dugi's Ultimate Wow Guide and Nyhm's Warcraft Guide offer great tips and secrets on making gold. You will receive a package that includes everything you'll ever need to know about the Auction House and how to profit from it, your professions and questing.
