Ad attribution is the method that decides which ad, channel or click gets credit for a sale or other result. In Meta ads, a purchase is credited to an ad if it happens within a set time after someone clicked or viewed it, and the rules you choose for that time are called the attribution setting.
TL;DR
- Attribution answers "which ad earned this sale?"
- Meta credits an ad when the result falls inside the attribution window after a click or a view.
- Meta's default setting is 7-day click and 1-day view.
- Different tools use different rules, so their totals rarely match.
- Pick one setting for reporting and keep it the same every time.
- Attribution depends on Meta receiving the conversion, so tracking quality matters.
How does attribution work in Ads Manager?
When someone sees or clicks an ad, Meta records it. If that person later completes a conversion, such as a purchase, Meta checks whether the conversion fits inside your attribution setting. If it does, the ad gets the credit and the result appears in Ads Manager.
Meta can give credit for clicks, views and engagements. The default setting counts a purchase within 7 days of a click or within 1 day of a view without a click. A shorter, click-only setting counts fewer purchases and is stricter about what an ad earned. Our glossary entry on the attribution window explains the term itself.

Here is a made-up example. A shopper takes this route:
| Day | What happens | Who may claim it |
|---|---|---|
| Monday | Sees a Meta ad, does not click | Meta, with a view |
| Wednesday | Clicks an email link and browses | |
| Friday | Searches the brand and buys a $60 item | Search, and Meta if the view counts |
The store records one $60 order. The email tool, the search tool and Meta may each credit it, because each tracks its own touchpoints with its own rules. Add them up and you get more than $60, which is how channels together can report more revenue than the store made.
Neither number is false. They answer different questions. Meta's number says how many sales it can tie to its ads under its rules, while the store says how many orders happened.
What are the common attribution models?
A model is the rule for splitting credit when several touches lead to one sale.
- Last click. The final click gets all the credit. It is simple and favors channels near the purchase, such as search.
- First click. The first touch gets all the credit. It favors discovery channels.
- Linear. Every touch gets an equal share.
- Time decay. Touches closer to the sale get more.
- Platform attribution. Each platform credits itself based on its own data. This is what Ads Manager does.
Meta reports on its own platform rules. A cross-channel view needs a separate tool and a clear label.
How is attribution different from tracking?
Tracking records that something happened: a click, a page view, a purchase. Attribution decides who gets credit for it. If tracking misses a purchase, attribution cannot credit it, because the event never reached Meta. That is why fixing tracking comes first. Our page on Meta pixel and GA4 differences shows how two tools can track the same site and still disagree.
How do I choose an attribution setting?
- Match it to your buying cycle. A fast, low-cost product fits a shorter window. A considered purchase may need a longer one.
- Start with the default if you are unsure, because it is what most reports use.
- Report click-only results beside the default if someone doubts view-through credit.
- Do not switch mid-test. Changing the setting changes the numbers and makes periods incomparable.
- Write it on the report. Every number needs its setting beside it.
When does attribution matter most?
When you decide where to put the next dollar. If one channel looks twice as good as another because of its attribution rule, you can shift budget for the wrong reason. It also matters when a client or finance team compares platform numbers with revenue, and when you test a change. Our answer on why Ads Manager results differ from revenue covers the gap in depth.

FAQ
What is the default attribution setting in Meta ads?
The default is 7-day click and 1-day view. A purchase counts if it follows a click within 7 days or a view within 1 day.
What is a view-through conversion?
A view-through conversion is a purchase made after someone saw an ad but did not click it. Meta counts it if it falls inside the view window.
Is last-click attribution better?
It is simpler, not better. It ignores the earlier touches that led someone to the final click.
Why do two tools give different attribution?
Each tool uses its own rules and its own data. They count different touches and different windows.
Does attribution change how Meta optimizes?
Meta optimizes toward the conversions it can see and credit. More accurate tracking gives its system better signals.
