It’s one of the biggest headaches you face as a marketer.
Not only do you have to worry about the price you’re paying per click (CPC).
Most seasoned marketers know what it’s like to dish out cold hard cash for an ad only to have it not perform.
Even worse is when you spend money changing the copy and design with no real improvement.
It can make you feel like you’re wasting your time and money.
In the worst cases it can force you to scrap entire projects because you never build a big enough list.
