The Facebook attribution window is the period during which conversions are credited to your ads after a user interacts with them. This includes both click-through and view-through conversions.
Facebook’s default attribution setting is 7-day click and 1-day view, meaning if someone clicks your ad and converts within 7 days, or views your ad and converts within 1 day, that conversion is attributed to your ad.
Why the Attribution Window Matters

The attribution window directly influences how your Facebook ad performance data appears in Ads Manager. Choosing a shorter or longer window can significantly alter your reported metrics such as click-through rate (CTR), conversion rate, and return on ad spend (ROAS).
For example:
-
A longer attribution window may report more conversions, but it might include customers who interacted with other marketing channels before purchasing.
-
A shorter attribution window provides a more immediate view of performance but may underreport late conversions.
Statistic: According to Facebook data, 53% of conversions from paid ads occur within the first 48 hours after the initial click.
Choosing the Right Attribution Window
Most Facebook-attributed conversions (via 7-day click window) occur within the first day, with diminishing volume over days 2–7 and 8–28
Your choice of attribution window depends on your business model, sales cycle, and campaign objectives.
-
Short sales cycles: For fast purchase decisions, a 1-day click or 7-day click window might work best.
-
High-ticket products or B2B leads: Longer consideration periods may benefit from a 7-day or even 28-day click window.
-
Brand awareness campaigns: A view-through attribution can help measure the impact of impressions on conversions.
How It Impacts Optimization
The attribution window affects how Facebook's algorithm learns and optimizes your ads. A misaligned setting could lead to:
-
Underreporting of conversions and poor optimization signals.
-
Misinterpretation of cost per result, leading to ineffective budget allocation.
-
Skewed ROAS data.
Statistic: Campaigns optimized using an appropriate attribution window can see up to a 20% improvement in cost per acquisition (CPA) according to Meta's internal studies.
Best Practices
-
Test different windows to see how they impact reported performance.
-
Align attribution with sales cycle length for more accurate reporting.
-
Evaluate across channels to understand the full customer journey.
