The NPC scan and NPC alert method is an awesome way to build a stock of rare BOE items simply because you don't really have to try.  By installing NPC scan and NPC alerts, you can literally just fly over anywhere and be alerted when you pass a rare spawn.  As we all know, rare spawn loot tends to have higher item vales, as not everyone is able to consistently farm them.  Some NPC's, especially those in outlands have those higher item values when compared to the rest of the world.  As a goldmaking method I just everyone should be doing this.  It only requires you download two addons and you can get access to important NPC,s that you would otherwise never knew existed.  The opportunities are endless, I would generally never play without these cool addons.  Realy cool.
Make WoW gold in BfA by making the most of the valuable components in Battle for Azeroth. In BfA, gathering has become more valuable than ever with Herbalism and Mining specifically being lucrative sources of WoW gold. This BfA Gold Guide focuses more on Herbalism than Mining but it you prefer to not take Enchanting or a crafting profession, then mining is a strong choice that lets you increase the amount of gold you can farm while out grinding Herbs for gold. This video was created in World of Warcraft, BfA patch 8.0.
The leveling guides on my site are essentially speed leveling guides.  My leveling guides are the same guides I use myself to speedrun to 60 on new servers.  I list many occasions where I tell the player to "die on purpose" to go faster.  I tell the player to skip certain quests, because some quests are just not worth the time/XP.  I list tricks and shortcuts to go faster so you can reach level 60 much quicker.  I am still constantly going through them over and over again perfecting the guides to make them faster and easier to follow.  For the most part, the guide can be followed without the need from other player's help, as the whole guide was made from a solo run anyways.  Although I do list quests that can optionally be done if you have a group.  My leveling guides also work great for duo leveling.
Using this book and the 'thottbot' website will save you a LOT of time. First, read the manual that comes with the game. Then read the sections in this book on how to get started if you are not a veteran player of games of this type. Then play. Use 'thottbot' (and the maps in the book) for reference of every detail like where to find a 'green whelp scale.' (I just did this.)
 ":"  -  Any time a step ends in a ":" instead of a "." means that the next step is part of the current step you are on.  This generally means the next step should be done while working on the current step.  This means every "start working on" or "continue working on" will end in a ":".  But this is used with other occasions as well, so keep this in mind.
You’re after all the items to make the Super Cooling Module from Shadowmoon Valley, Nagrand or Talador, and the Cyclical Power Module from Frostfire Ridge, Gorgrond or Spires of Arak. Some are worth only a few hundred but I’ve sold a few for over 20k. They drop from any mob in the zone. I haven’t found an optimal spot, but all these zones have plenty of areas with densely packed mobs.
This is a once size fits all pet farm that can generally leave you with a small sum of gold if your server is low on this specific pet. (You can always check on the undermine journal).  It takes place in the Ihgaluk crag and is generally performed by sweeping the oozes in the small muddy pools surrounding the area.  An easy spot to hit, that really isn't farmed all to often.  I was able to get one in the video after a small 24 minutes.
This tutorial will ensure that the beginning of your journey will be a smooth one. It provides information that will help you find your way when you get lost, as well as tips that will offer guidance and advice as you march on towards greatness. It is not an exhaustive guide, however; it neither can nor wants to unveil every secret of Azeroth to you. That glorious task is left up to you as you explore the world yourself. Think of this guide as a touchstone for your early adventures: enough to get started, but too little to spoil any of the awesome surprises that await you in Azeroth.

Okay, this farm really picked up steam here in late legion.  Generally what we're looking for is volatile air, and other volatiles when combined with the potion of treasure finding.  This farm is as easy as pulling the entire instance all the way to the first boss – and AOE'ing down ebery mob that follows.  In the video you can see me getting volatile airs in stacks of 11 for each pull I make.   Wit the trending price of each volatile being worth at least 100g, I was making 1100g per pull.  It's by far the most effcient volatile spot, but it has hits limits as you can only reset an instance 10 times before you have to wait a while to do it again.  If you only going to be on for an hour or so, this is the spot you want to hit.  It's great, fast, and awards a high liquid value of items.  Awesome Stuff.
Cool the whlelping spot that has caused so much controversy int he gold farming community.  I still think spot is mentionable because it's really the only reliable spot to pull out a crimson whelping.  Most of you are probablly thinking this farm is old and beat to death, and you are right.  BUT that does not take away the fact that the whelping does drop highest from this farm.  If you can get it from the slavemasters your looking at anywhere from 25,000g and above.  A cool nifty old spot, that has survived the test of time.
The last farm on this list, actually I was surprised this farm eluded me for so long.  Generally speaking gnomergan is a huge confusing instance that takes some getting used to but if your a high value transmog farmer this does not scare you.  You can pull the entire instance and get access to a plethora of high value loot such a recipes, world drops, greens and even engineer supplies.  Overall this farm is shadowed by the Diremaul farm and Zulfarrak farm, but is an equal change of scenery with a wild card if you get the hot shot pilots gloves OR the mechbuilders overalls worth 400,000g and 60,000g respectively.  A pretty cool neat farm that noone really mentioned until now.
This is an infinte farming spot that takes place just east of maraudon.   It requires you to stand in a specific spot which will allow you to kill all the slitherblade naga that surround the river.  This spot is generally a GREAT spot since the mobs respawn instantly after death.  You will get an obscene amount of silk, wool, greens, and low level patterns.  It's one of the only remaining infinite respawn farms left in the game.
Heirlooms: Heirlooms are the best source of bonus XP for leveling. All slots can be gotten pretty easily now, except the rings. The time you need to spend to get the rings if you haven’t gotten a level 3 shipyard in WoW is way too long, so getting the rings is generally not worth it. Having all your heirloom gear will boost XP by 55%. Generally, you want heirloom gear with crit on for leveling as you want to kill mobs in a few hits as possible
War Mode: War Mode can be turned on at level 30 through your talent window, and will give you 10% bonus XP. You will, however, be attackable by players of the opposing faction, but changes have been made so that all players have a fair shot in a fight and even low-level players can kill much higher level players, and at least not get ganked and one shotted. Note: As of patch 8.1, you can get an additional call to arms bonus with war mode on if your faction is underepresented.
