Placing a lot of focus on Audience Overlap in your Facebook campaigns is distracting you from the real problem...
Many people put a lot of weight on audience overlap and for good reason.
If your audience overlap is high, you'll not only be showing your ads to the same people over and over again, you'll also be competing against yourself in the auction (<--not good).
But believe it or not, audience overlap isn't THAT big of a deal.
The real enemy is AUCTION overlap. It's a little known metric that most people don't know about and have no idea where to find it.
In this video, I break down why advertisers should focus more on auction overlap and where to find it within Ads Manager.
