> Quick answer: Facebook's default attribution window is 7-day click plus 1-day view. Short-cycle products do better with 1-day click. Long-cycle products benefit from the full 7-day window. Match your window to your customer's decision timeline and track results consistently.
How Attribution Windows Control What Facebook Credits to Your Ads
An attribution window is a timeframe. It tells Facebook how long after an ad interaction to credit a conversion to that ad.
Definition and core concept
Per the Meta Business Help Center, an attribution window defines when Meta attributes a conversion event to an ad impression or click. A user sees or clicks your ad. If they convert within the window, Meta counts it as a conversion for that ad. No window, no credit.
Click vs. view attribution
Click attribution counts conversions from users who clicked your ad. View attribution counts conversions from users who only saw your ad without clicking. Both measure real behavior. But they measure very different kinds of intent.
Why attribution windows matter for advertisers
Your attribution window directly shapes your reported ROAS. A wider window captures more conversions. A narrower window shows only fast movers. Choose wrong and your campaign data will mislead your budget decisions.
The Four Attribution Windows Facebook Offers (and When to Use Each)
Meta offers a defined set of windows. Each suits a different scenario.
7-day click attribution (7d_click)
This window credits conversions that happen within 7 days of a click. It captures users who needed time to decide. Good for higher-consideration purchases where buyers research before acting.
1-day click attribution (1d_click)
This window credits conversions within 24 hours of a click. It shows fast, intent-driven behavior. Good for impulse buys or flash sales. Per Meta's developer documentation, the Inline Link Clicks metric itself uses a fixed 1-day click-through attribution window (1d_click).
1-day view attribution (1d_view)
This credits conversions within 24 hours of an ad impression. No click required. It measures brand influence on people who saw the ad but did not engage directly.
Default setting: 7d_click + 1d_view
Meta's default attribution window combines both. It counts conversions within 7 days of a click and within 1 day of a view. This default captures the broadest set of conversions Meta can reasonably attribute to your ad.
How to Choose the Right Attribution Window for Your Business
Match your window to how your customers actually buy. There is no universal right answer.
Short consideration products (impulse purchases)
Fast-moving products like low-cost accessories or flash deals convert quickly. Use 1d_click. It gives you the truest signal for fast-converting traffic and keeps your reported numbers honest.
Long consideration products (considered decisions)
Software, furniture, travel, or B2B services take time. A 7d_click window gives those buyers room to come back. You will capture conversions from people who researched before deciding.
Multi-touch customer journeys
Some customers see multiple ads before converting. The 7d_click plus 1d_view combined window helps you see the fuller picture. View-through attribution adds context for awareness-stage campaigns that warm up cold audiences.
Testing and optimization
Run campaigns with the same window across your test periods. Changing the window mid-test distorts your comparison data. Keep it consistent, then review results once the campaign period ends.
How to Change Your Attribution Window in Ads Manager
Facebook Ads Manager lets you view and configure attribution at the account and reporting level.
Locating attribution settings
Open Ads Manager. Go to the campaign, ad set, or ad you want to review. Click the "Columns" dropdown. Select "Customize Columns." Attribution window options appear in the conversion column settings.
Selecting a custom window
Choose from the available windows: 1d_click, 7d_click, 1d_view, or the combined default. Apply it to your reporting view. Meta recalculates the conversion data for that window immediately.
Applying changes across campaigns
Attribution window changes affect reporting, not ad delivery. The delivery algorithm already uses the window set at campaign creation. Reporting changes let you analyze performance under different assumptions without touching live delivery.
Reporting with your chosen window
Once you select a window, your conversion columns update. Review cost per result and ROAS through that lens. This gives you an apples-to-apples view across campaigns using the same window.
Best Practices for Attribution Window Configuration
A consistent, intentional approach keeps your data clean and your decisions sound.
Match window to customer journey length
Short-cycle purchase? Use 1d_click. Long-cycle purchase? Use 7d_click or the combined default. The window should reflect realistic buyer behavior, not just the widest possible credit.
Monitor conversion trends across windows
Pull the same campaign data under different attribution windows. Compare the numbers. A big gap between 1d_click and 7d_click often signals delayed decision-making in your audience. That gap tells you something important about how your customers buy.
Communicate attribution choices to stakeholders
If you are reporting ROAS to a client or manager, state which window you used. A 7d_click ROAS and a 1d_click ROAS for the same campaign look very different. Transparency avoids confusion and builds trust in your reporting.
Track performance consistently
Do not switch windows between reporting periods without a clear reason. Inconsistency creates noise in your data. Pick a standard and stick with it until you have a deliberate reason to change. Brand Profile stores your funnel context so every AI-generated creative and copy variant stays aligned with the offer you are measuring.
Optimize Performance with Better Reporting
Accurate attribution is the foundation of smart optimization. If your conversion data reflects the wrong window, your budget decisions follow flawed signals. You will scale what looks good on paper, not what actually drives revenue.
Meta's iOS privacy changes under Apple's ATT framework have made this even more critical. Some conversions go untracked due to user opt-outs. A well-configured attribution window captures as much signal as possible within those constraints, per Meta's own guidance on the impact of privacy updates on measurement.
The Coinis Advertise page surfaces live performance data, including cost per result, ROAS, and conversion volume, filtered by your chosen attribution window. Act on clean signals without exporting CSVs. A mismatched window can make a 1.8x ROAS campaign appear to perform at 3.2x, or the reverse, depending on your purchase cycle length.

Frequently Asked Questions
What is the default Facebook attribution window?
Facebook's default attribution window is 7-day click plus 1-day view (7d_click + 1d_view). This means Meta credits a conversion to your ad if the user clicks your ad and converts within 7 days, or sees your ad and converts within 1 day.
What is the difference between click and view attribution on Facebook?
Click attribution counts conversions from users who clicked your ad before converting. View attribution (also called view-through attribution) counts conversions from users who saw your ad but did not click. Both are included in the default window setting.
Can I change my attribution window in Facebook Ads Manager?
Yes. In Ads Manager, use the Columns dropdown and select Customize Columns to change the attribution window for your reporting view. You can choose 1d_click, 7d_click, 1d_view, or the combined default. Note that changing the reporting window does not change how the algorithm delivers your ads.
How have iOS privacy changes affected Facebook attribution?
Apple's App Tracking Transparency (ATT) framework allows users to opt out of cross-app tracking. This means some conversions from iOS users may go untracked in Meta's system. Configuring your attribution window carefully and using the Meta Pixel correctly helps capture as much conversion signal as possible within these constraints.
