Huh, we know that WoW Gold is always a concern for every World of Warcraft player whether it's for a flying mount or for an epic piece of gear, gold is without a doubt the most crucial component in WoW since it first released. Here now, Maybe someone would recall the topic WoW Power Leveling, ok, but today we are talking about gold.  
While there are hundreds of time tested methods of making gold in WoW perhaps the funnest method is grinding. I know, grinding doesn't sound fun at first, but when you start to see your bank account grow at a ridiculous rate the fun really starts to build up if you would grind some rather than buy Cheap WoW Gold from the online stores.
So if you really like to do it yourselves and wanna to experience a different feeling, I would like to tell you something about how to grind more gold in WoW. Well, the key to grinding out WoW Gold in Northrend, as well as any other zone, is to find an area with the following:
1. Mobs that carry gold. Generally humanoids are the best
2. Mobs that drop a variety of items. From grey items to blue items everything in Northrend is worth something. Even a lowly grey broken sword will get you 2-3 gold and if you can get 5 of those in less than 30 minutes that's an easy 15 gold on top of everything else you'll get.
3. Mobs that can be killed quickly. This usually is more of a level issue, a good rule of thumb is to go at stuff that is three or four levels below you. The reason you do this is because it's easier to kill large groups without taking on to much damage and downtime.
4. Groups of quickly regenerating mobs. The faster they respawn the quicker you can kill them and take their Cheap WoW Gold.
Keeping these four things in mind perhaps the best grinding spot for quick gold in Northrend can be found just south of Venomspire in Dragonblight. The area is chalk full of humanoid mobs and they are of a relatively low level.  
Grinding for gold in WOTLK doesn't have to be a horrible experience especially if the rate of return is very high. This is just one grinding spot and one method of getting gold in WOTLK, there are many more out there some of them returning a much better rate of gold per hour. Happy hunting.
