I'm looking for some good explanations/guides/tutorials for paid advertising. I wanna do a lot of research and stuff before I begin. I've read a few, but I am not sure which ones are the best that are must-read with good explanations. Don't get me wrong, I'm not new to IM, I have a lot of knowledge of many things, but I am new to paid advertising and campaigns, so I'd like to do a good research before I make my first campaign! Even some journeys of people explaining how they've done it is great. Anything that's worth a read related to paid advertising, please share Thanks in advance.
