Key takeaway
Meta and Google Analytics usually disagree because they credit conversions differently. The right question is not which dashboard looks prettier. It is which comparison changes the decision you need to make.
Why the numbers differ
Meta can credit click-through and view-through conversions based on its attribution settings. Google Analytics usually follows a different click-based model and has less direct visibility into impression influence. That alone creates disagreement, especially when tracking post-click conversion quality.
Attribution settings change the story
If Meta is using 7-day click and 1-day view, it will usually report more conversions than a stricter analytics read. If you tighten the attribution window, Meta can suddenly look worse even when the business did not materially change—avoid misinterpreting sudden drops from attribution changes.
Other reasons the numbers drift apart
- iOS privacy loss and browser tracking limits.
- Delayed conversions that happen after the first visit.
- People returning directly later instead of through the ad click.
- Different rules around view-through credit.
- Different date windows and comparison methods.
Common mistake
Do not compare campaigns using different attribution settings and call the difference performance. Keep the attribution standard stable while you judge whether the account is actually better or worse.
How to compare safely
- Keep the attribution setting consistent while evaluating performance.
- Read the last 7 days instead of reacting to one day of mismatch.
- Compare Meta against analytics, CRM, and actual revenue together.
- Ask whether the disagreement changes the business decision, or only the story you tell about it.
What to trust most
If every source says performance is down, it is probably down. If only Meta says performance is strong, require confirmation. If Meta looks weak but revenue is holding, attribution loss may be the better explanation than campaign failure.
The working rule
Attribution disagreement is normal. Do not let two dashboards arguing with each other push you into cutting a campaign that the business still needs.
