For a long time, a like and a link click looked the same in Meta's attribution model. Both counted as conversions. Both padded your numbers. And when clients compared what Meta reported to what GA4 showed, the gap was impossible to explain without a long, uncomfortable conversation about how platforms define things differently.
That gap wasn't an accident. It was a measurement choice that happened to make Meta's numbers look better. Now they're walking it back.
Starting this month, only actual link clicks count toward click-through attribution for website and in-store campaigns. Likes, shares, saves - none of it qualifies anymore. Those interactions move into a separate category called "engage-through attribution," which is a rebranded version of what Meta used to call engaged-view attribution. The social actions still get tracked. They just stop inflating the number that your clients think represents real purchase intent.
The video window is tightening too. Engaged-view attribution drops from 10 seconds to 5 seconds. Meta's justification is that nearly half of Reels purchase conversions happen within the first two seconds of someone watching. Whether you find that convincing or not, the practical outcome is the same: fewer view-based conversions get counted than before.
Neither of these changes affect billing. Worth saying twice because clients won't hear it the first time.
What does change is the number on the screen. And a number that drops without explanation will always look like a problem, even when it isn't. Agencies that get ahead of this will have a straightforward story to tell. Agencies that don't will spend the next reporting cycle defending performance that didn't actually change.
its definition of a conversion click so the numbers align
Pull your current baselines before the rollout hits your accounts. Document what the numbers look like today. Then reach out to clients before they come to you. The message doesn't need to be complicated: Meta tightened its definition of a conversion click so the numbers align better with tools like GA4. Fewer things count now, but the things that count actually mean something.
