To give you some perspective I leveled both a LF Ret Paladin and BE Rogue (so one started from level 20 and the other from level 1). I focused on getting the achievements I was missing for the Loremaster, so not the most efficient route by any means. I was using full enchanted heirlooms (minus the ring) and the WoW-Pro addon though, as well as having War Mode turned on all the way.
World of Warcraft: Battle for Azeroth is an expansion set on the high seas full of trolls, pirates, and troll pirates. At the heart of this expansion is a renewed focus on the conflict that started everything: the monstrous Horde duking it out with the noble Alliance. The expansion will offer two new continents and a level cap of 120, several new races to unlock, 10 new dungeons, and exciting new activities like the real-time strategy inspired Warfronts, where 20 players will siege fortresses in a Warcraft 3-style campaign complete with base building, researching, and more. At the center of Battle for Azeroth is the raging conflict between the two factions at the heart of World of Warcraft. With the Legion defeated and the external threat to Azeroth now gone, the Horde and Alliance are turning on one another and seeking new allies to bolster their ranks. Capital cities have been razed in the opening blows, and players are setting out on the high seas to the new continents of Kul Tiras and Zandalar in hopes of securing a foothold against the other.
This farm almost did not make the list, since every YouTuber and farmer alike has beaten it to death since it first appeared sometime in 2012.  There are so many videos on this spot, that it's hard to to stumble across one, even while searching for something completely mundane, like chicken wings or golf clubs.  Anyway, you want to pull the entire instance without aggroing any of the bosses, and if your a skinner you an make slightly more gold by skinning the hides.  Generally this farm is being phased out by the lvl 58 twilight outpost farm, and with good reason.  It's better and does not require you to enter the instance.  So more drops for you!  Not sure, why anyone would pick this spot over the latter unless you were really interested in increasing you skinning level.
Blizzard has taken steps in recent years to smooth out out the leveling experience — Legion allows players to immediately boost one character to level 100, for instance — but if you want to roll multiple characters without spending money on multiple level boosters, you’ll need to spend time leveling. Thankfully, with the right maneuvers, it’s possible to level a character to 110 in a relatively short time. Here are some pointers for leveling in World of Warcraft, so you can rush through old zones and explore the new.
YouTuber Oldbess recently uploaded a video about this cool method.  Generally completing the scenario "Deaths of Chromie" will allow you to pick up the item "Time-Lost Wallet" in excess.  You can get it from just killing the mobs or actually completing the scenario in full.  By then end you will have dozens of time lost wallets.  Each wallet awards 50g AND a rare chance at getting the ]bronze proto-whelp[/U] pet.  In the video, this spot was VERY hard for to pull off as it requires a high item level.  With an 809 item level I struggled all throughout the scenario and could not make this spot profitable for the time invested.  The good news is, if you can get it done, the gold you make will be entirely liquidated – the rewards are 50g raw for each wallet turn in.  I suggest you watch it on Oldbess's channel for full details.
Note that these general principles do not apply to blue or purple items. If you are a first-time player, there is absolutely no reason to purchase these items. None. Sub-80 rare and epic items are only for the alts or twinks of established players that have money to waste (because that's what it is) by showing off their Staff of Jordan (or whatever). Blues and purples are completely cost-ineffective for first-time characters. Within a few levels, you will find green gear that is roughly comparable, or you'll get better blues from instance runs at the same level. So, do not buy these items, under any circumstances, if you are a first-time character (no matter how cool they look). And even if you're reasonably well-off financially, think twice. This is especially true as your character gets closer to levels 58 and 68. Even the most basic quest-reward gear in Outland will have substantially better stats than anything you can buy off the AH for a level 56 character. The same is true of Northrend gear at level 68 vis-a-vis the stuff you'll get in Outland at level 68. As such, smart players stop making AH gear purchases by about level 54 or so, and then just gut it out until level 58. The same is true at levels 64-68. Within the first several quests in Hellfire and/or Northrend you'll have replaced half of your gear in any case, guaranteed.

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.
Heirlooms can certainly be used with our guides! You may find yourself getting ahead of the guide. If you start doing gray quests, just skip ahead to a later zone. The guide is just that - a *GUIDE* not a rule, as many people seem to think. Feel free to skip parts! Watch out for quest chains, though, especially in the last part of the 50-60 section. Hopefully we'll have some awesome features in our new addon that will make it easier to skip around!

Improper leveling of your production profession skills can cost a small fortune. Heck, even proper leveling of some production skills can cost a small fortune. And keep in mind that equipment you produce using your profession will typically be slightly worse than equipment otherwise obtainable at your level via the Auction House and/or instances. It is therefore strongly recommended not to take on a production trade skill until you hit at least level 30, or better yet, level 70+. However, if you are determined to take on such a profession (particularly under level 30), read a suitable leveling guide in order to gain whatever skill level you desire for the least amount of money.
For reference, my previous best time abusing Method-0 in 7.3.5 was 32.4 hours(as show in the old thread). A difference of just over 8 hours; which isn't all that bad, all things considered. And I believe I made several errors along the way, which could be cleaned up in future runs. I believe that that gap could be significantly closed by using a monk's bonus, but I hate playing monk...so...yeah. YMMV

The most simple thing is TradeSkillMaster. This AddOn shows you quite an amount of information in the items tooltip. In my opinion, DBRegionMarketAvg the best source. It tells me the price, an item was posted on all EU realms in the last 14 days. Why not DBMarket? DBMarket only shows you the items value from your server in the last 14 days. This value often gets manipulated. Some people start to post an item with a 500g value for 500.000 Gold on the auction house for several weaks. As a consequence, DBMarket is rising towards 500.000 Gold.  If you use DBMarket with 100% and post your item for 500.000 Gold, nobody will buy it.
