In 1948, the Chicago Tribune infamously printed "Dewey Defeats Truman" headlines before the final votes were counted in the U.S. presidential election.
They were confident in their prediction, relying on polls that showed Dewey consistently in the lead.
However, when the votes were tallied, Truman emerged the victor.
The pollsters and newspapers had egg on their faces.
They thought they had enough data.
But they failed to account for ALL the data.
They didn’t account for the preferences of working-class and rural voters, who largely supported Truman.
Today, Facebook marketers are facing their own "Dewey Defeats Truman" moment.
They pour their heart and soul into crafting the perfect campaign, and tirelessly refine ad after ad in hopes of boosting sales
Despite their best efforts all of this is not enough to overcome the lack of data being fed back to Meta post iOS.
Facebook’s tracking, similar to polls in the past, used to be accurate, but changes in privacy laws, technology, and consumer behavior have hindered its ability to track site visitors effectively.
Incomplete data presents a significant obstacle to the optimization of ad accounts.
Incomplete data leads to incomplete optimizations.
Incomplete optimizations leads to missed opportunities, and wasted ad spend.
Post iOS 14.5, Meta has increasingly relied on modeling in order to manufacture targeting for your campaigns, making first-party data collection, storage, and reactivation pivotal for campaign success.
Implementing robust first-party data delivery systems is no longer optional if you want to produce:
✅ Retargeting campaigns that work
✅ Campaigns that scale
✅ Lower CPAs while increasing ROAS
Don’t be the Facebook marketer left with egg on your face because you procrastinated on implementing first-party data systems.
