Seems everyone is asking "where is the place for gold?" or "I'm broke and need gold fast, please tell me where?" This article should help you out. Here I will list just some of the methods because there are too many to write but farming or getting world of warcraft gold is EASY! Think outside of the box...
You can farm normal rock elementals in the south, middle edge of The Badlands zone (nestled in a small valley). They drop a lot of grey loot that vendors for 50silver to 1.5 World Of Warcraft Gold and drop it every other kill. They also drop ELEMENTAL EARTH which sells on the ah for 1-3 World Of Warcraft Gold A PIECE. Average drop of the earths is 1 out of 17.
You can farm elemental slaves on the west side of Alterac mountains (horde only) for the chance to get elemental earths (1 out of 15 kills). Goes for 1-3 World Of Warcraft Gold a piece on Auction House.
Can farm elemental exiles on the southwest area of Arathi Highlands for elemental earths. Same 1-3 World Of Warcraft Gold per earth on AH.
Can farm Dabryie's farm in Arathi Highlands (horde only) for 30 npcs of 2-6 silver each on 3-5 minute spawn timers. Often times not camped. Easily can generate 1-5 World Of Warcraft Gold an hour, more if you are an AOE class.
Can farm Go'Shek farm in Arathi Highlands (alliance only) for 30-40 npcs of 2-6 silver each on 3-5 minute spawn timers. Often times not camped. Easily can generate 1-5 World Of Warcraft Gold an hour, more if you are an AOE class.
You can area of effect the scarlet monastery graveyard (in Tristfall glades northeast corner of map) for a good 2silver - 6 silver per kill. An aoe class can easily farm and reset the instance for a good 30-60 World Of Warcraft Gold an hour.
You can farm warpwoods and deadwoods (funny, walking tree treant guys) for 2-10 silver, rare herb drops that sell for 1-5 World Of Warcraft Gold EACH, major healing potions (sells for 1-1.5 World Of Warcraft Gold each on my server), and Living Essences (sells for 8-14 World Of Warcraft Gold EACH on AH!). The warpwoods are located on the north side of Felwood zone near the alliance flight path person. The deadwoods are located just southwest of where the warpwoods are. I made an easy 40-80 World Of Warcraft Gold an hour depending on AH prices with my 60 PALADIN. If you have any other faster dps class, you can EASILY get DOUBLE the World Of Warcraft Gold per hour I got (I should've rolled a different class.... *cries*).
You can farm twilight hammer elites in Searing Gorge. They are located JUST WEST of the alliance/horde flightpoints. You can easily get 3-5 mageweave cloth per drop and about 2silver-16 silver per kill, with 9/10 silver being the most common drop of coin. Easily can make 10 World Of Warcraft Gold per hour off coin drops and 5-20 World Of Warcraft Gold per hour off the green and mageweave drops.
And there are many more spots if you take the time to look. This short list should help you.
