You get an email from Google, Facebook, Instagram or Twitter that says you have $50 or $100 to spend on paid advertising and you think, “What the heck – it’s not my money. It’s theirs. Let’s try this.”
Seems easy enough. You follow the link and create an account. You log in to the dashboard and think “Damn, this looks easy” so you create your first ad and push the submit button.
The next day, you check your Google Analytics (you did remember to set that up didn’t you?) and you notice that there was no additional traffic to your website. Not only that, all of your “free” money is gone and your account says you owe an additional 50 bucks.
