The first thing in WoW you should do to make gold is get a profession as it does have gold making benefits.
The best professions in my opinion are mining and skinning as you kill higher level creatures in World of Warcraft you can skin them and sell there coats for big money! The more you do this the higher the level of that profession goes so you will be able to skin bigger and better animals and thus make more gold.
The mining profession is another profession mentioned in Wow Gold Secrets and can make you huge amounts of gold if you know what you are doing! You will often run into caves on quests and missions which have ores in them that are very profitable! Some of these rare ores you can put in an auction house and make huge sums of money!
Another aspect of the game that is mentioned in WoW Gold secrets a lot is how you can make a fortune by just doing quests! You should try to grab a quest in the game every chance you get as it not only boosts your XP but also can make you a lot of money just by grinding mobs!
Another much overlooked way that is mentioned in WoW Gold secrets is how to make gold with gears! Gears in Wow can get very expensive but if you are selling them can make you a huge amount of gold. A lot of guides tell you not to bother with gears in WoW until you are level 40 but WoW Gold secrets shows you ways to make good gold before then!
Also the last thing you should look for that will make you good gold is not how many creatures you kill but which specific creatures you kill will matter a lot in how much gold you make in WoW. Humanoids tend to be the best in having loads of cash so attack every one you see!
