What makes an ad compelling to drive enough sales?
Short answer — You.
I’m sure you’ve probably heard this so many times that it has now become boring to you; but it’s actually true that people buy from those they know, like, and trust.
Depending on the context, this know-like-trust factor can be achieved in 1 hour, 1 week, or 1 year. But irrespective of how long it takes to build, having that credibility is very important to the success of your business.
