WoW Gold Guide

I wanted to see if there was a legitimate WoW gold guide somewhere on the internet. I was browsing around and saw ones such as Hayden’s guide and the like, however I can’t tell whether these are scams or not. Can someone let me know of a guide that isn’t a scam? Personal experiences using these guides would be best.

Note* I am not looking for a website to buy gold, but rather a guide that gives advice/tips for making money legally in the World of Warcraft.
