The first way for WOW Classic Gold farming is to gather and sell as your level. From 1-60, you can only choose gathering professions. Usually, this will be herbing and skinning, or herbing and mining, but enchanting is also important. Don’t collect the items for yourself but sell them to others in traditional crafts.

Professions

Perhaps the best way to make gold in WoW is professions. Many are very profitable and will most likely take the same amount of grinding to fully level them up. There are gathering professions (Herbalism, Mining) and crafting professions

Play the Auction House

The Auction House is one of those hidden gems that can help you earn lots of gold in WoW. The basic premise is buying low and selling high. The other thing to do is to corner the market. Buy up all of an item (usually a trade skill item—herbs, metal, etc.) and resell them at a much higher price. It requires constant commitment, though.

To get the flow of gold going, you will have to let your items expire and then re-list them immediately. You have to find new items to buy depending on what is the demand at the time, so ensure you keep up with the trends of what item is needed at any given time. A new patch can throw the market into chaos, which is the best time to pick up a lot of gold or a lot of items cheaply.

The Auction House has gone through a lot of changes to prevent scams, so while it may not be the gold mine it once was, it can still be profitable.

Keep in mind you will lose money sometimes and you won't always be able to sell every item. There are times you need to cut your losses and move on!

Farm Dungeons

With some company, visit the dungeons – or return to low-level dungeons after reaching level 50 at least, to collect a variety of useful loot left behind in solo mass killing. Hunters, sorcerers, and mages have this advantage over others – their location comes with plenty of goods. Endgame materials such as Stratholme, Scholomance, Dark Runes, Righteous Baubles, and essences of Undeath, are especially worthwhile. Low-level dungeons are easier and have lots of trash mobs, therefore, should be used for resource-gathering, since the collected items promise a secure income.

Bank Alts

If you are serious about making gold, a bank alt is essential. This is to save time as you level or farm with your main, you can just mail all the stuff that you want to sell on the Auction House to your alt.

Get your bank alt to level 5 and get the Enchanting Profession, so that you can disenchant gear. Some gear will make a lot more gold if you disenchant it.

Fishing

Most people are aggravated by constant ‘blinker staring’, but we’re here to tell you that fishing is worth the while. In higher fishing levels, you can find rare fishes that will fetch a handsome amount at the auction house. Alchemist, for example, need these rare types to make basic materials: Stonescale Eel, Stonescale Oil, Nightfin Soup, and Nightfin Snapper. Chefs also love cooking fish, and besides, you could also east the fish since they are easy to prepare and save the cost of buying food. You can, therefore, fish as a side hustle and find some bales of herbs and materials in the process.

World Quests

Not a lot of people are aware that World Quests are a great tool for making gold in WoW. Here we’re talking specifically about the World Quests that give gold as a reward for completing them. On a good day, there are 15+ such quests throughout the map, and each of them gives somewhere between 100-250 gold. However, if you play with a War Mode on, you can go up to 30% in bonus. So, we’re looking at about 3000 gold in total.

But the real power of this method is that you can repeat this on all characters! The World Quests are amazingly easy to complete and won’t take too much of your time. And if you complete them on at least 3 characters, then you’re looking at some easy 9000 gold per day.

It's important to understand that Gold is a lot harder to make in the Classic version of World of Warcraft, you can buy WOW Classic Gold in some stores when your inventory is in short supply, as you can't do all the quests on your own. Here is a good store to trade gold, https://www.igvault.com/WOW-Classic-Gold  , becoming the nice assistant while playing.You are worried about the price and security, with this in mind, it can be guaranteed on the site, which is cheaper than other stores and protected by a security system.
