Making real money from playing World of Warcraft may seem like a pipe dream, but its very possible. Most of the ways to make money playing World of Warcraft involve breaking the ToS (Terms of Service) agreement that you agree to when you log in to play. Now this is not illegal, but can get your account suspended or even permanently banned if caught. If your account is invaluable to you then I suggest not following these tips, or creating a new account to use them on.
There are many ways to make money playing WoW, the first of which is selling gold. In order to sell gold you will need to either be able to grind a lot of gold yourself in a short amount of time for it to be profitable, or to download a bot to do it for you. Bots are great because you can go away from your computer and it will still be running, making money for you 24/7. Another great thing about bots is that if you have multiple accounts to use it can play them all at once, no longer will you only have to focus on one of your characters at a time. Now all of your characters can be used to their full money making potential.
Once you have amassed quite a large amount of gold you are going to need to sell it off. The easiest way to do this is to go to a popular gold selling site such as Mogs.com and go to their selling section. The only problem with this is that you will not get very much money for all the gold you have acquired, it is simply the fastest way to unload it. Currently gold prices are about $3/1000g if you sell it to a major website. If you feel like trying to make more money with your gold you can make a trial account and offer your gold for sale to players in WoW, you can usually get close to market price this way because players rather by from someone trustworthy than a Chinese gold farming site and risk getting banned.
The second way to make money in World of Warcraft is to sell your account. Again you could hand level accounts and then sell them once they hit level cap, or you could bot multiple accounts at once to greatly increase your profit. Once you hit level 80 you can either sell it off right away, or try and obtain better gear for the character to increase the accounts value. When you are ready to sell your account you can go directly to a site like Toonstorm.com and send in your characters profile for review, they will then send you an email quote with how much they will by your account for. But just like selling gold these sites will often give you much less than market value because they to are try to turn a profit. The best thing you can do is sell it on a forum site like Mmobay.net where you can post it up yourself and receive offers on it from other members, similar to craigslist.
Making money through World of Warcraft can take a small initial monetary and time investment, but once you get it going you can make good money if you stay dedicated to it.
