With iOS 14.5, every app must explicitly ask permission to track users. Many people will say no. For advertisers on Facebook and Instagram, that has big consequences.
What you will notice
Conversions from iPhone users are measured less well and reported later. Audiences based on website visits shrink. And the numbers in Ads Manager lag behind what you actually sell.
What you can already do
Verify your domain in Business Manager and choose your eight most important conversions. Set up the Conversions API, so data also comes in via your server and not only via the browser.
Look beyond one channel
Compare Facebook’s numbers with your own revenue and analytics. The gap is growing, and anyone looking only at the ad platform steers on an increasingly incomplete picture.
