What Is 7-Day Click Attribution on Meta? DTC Explainer

7-day click attribution on Meta Ads means any purchase that occurs within seven days of a user clicking your ad is attributed to that ad, forming the basis of Meta's standard performance reporting for DTC ecommerce campaigns.

What the 7-Day Click Window Means

When a user clicks one of your Meta ads, a 7-day timer begins. If that user purchases from your store at any point in the next 7 days, Meta credits that conversion to your ad, even if:

This is Meta's default attribution model and the basis of most platform ROAS reporting for DTC brands.

Why 7 Days?

Meta chose 7 days as the standard window because research showed the typical DTC purchase decision cycle for most product categories is 1-7 days. Users who see a product and are interested often do not convert immediately; they consider the purchase, do research, and return later.

A 7-day window captures this consideration cycle. Shorter windows (1-day click) miss purchases from users who genuinely needed more time. Longer windows (30-day) attribute too many conversions that have lost meaningful connection to the original ad impression.

For most DTC categories (beauty, fashion, supplements, home goods), 7 days is a reasonable approximation of the genuine influence period for a single ad click.

7-Day Click vs 1-Day Click

WindowWhat It CapturesBest For
1-day clickImmediate intent purchasesHigh-impulse products, direct-response campaigns
7-day clickFull consideration cycleMost DTC categories
1-day click ROAS is typically 30-50% lower than 7-day click ROAS for the same campaign. This does not mean the 7-day click is wrong; it reflects that genuine consideration purchases happen over multiple days.

Using 1-day click as your primary metric will cause you to undervalue Meta's contribution to your funnel and may lead to budget cuts on campaigns that are actually working well.

7-Day Click + 1-Day View (Default)

Meta's default attribution window combines:

The combined default therefore attributes to Meta all purchases within 7 days of clicking OR within 1 day of seeing your ad.

For a high-spend DTC brand with millions of daily impressions, the 1-day view component can represent 20-40% of total reported conversions. This view-through component inflates ROAS relative to click-only attribution.

When comparing your Meta performance to 7-day click benchmarks, check whether the numbers include or exclude view-through.

How to Check Your Attribution Window

In Meta Ads Manager:

    • Click the "Columns" dropdown
    • Select "Customize Columns"
    • Scroll down to "Attribution Window" section
    • You will see the current window (default: 7-day click, 1-day view)
    • You can select different windows to see how performance changes
To change the attribution window for a specific campaign:
    • Go to ad set settings
    • Under "Optimization and Delivery," click "Show more options"
    • Find "Attribution Setting"
    • Select your preferred window
Note: Changing this does not affect how Meta actually attributes conversions in the auction, only how it reports them to you.

Impact on ROAS Reporting

Understanding attribution window impact is essential for accurate performance evaluation.

Example from a DTC supplement brand:

The "true" ROAS is somewhere in this range depending on your view of each window's legitimacy. The 7-day click only figure ($3.6x) is typically the most reliable benchmark for comparing performance against industry averages or other campaigns.

When setting CPA and ROAS targets for your campaigns, be explicit about which attribution window you are using. Comparing a 7-day click ROAS target against a 1-day click reported ROAS creates false underperformance; comparing against default (7-day click + 1-day view) creates false overperformance.

Choosing the Right Attribution Window

For campaign optimisation: Use the default 7-day click + 1-day view. The algorithm uses this window to optimise your campaign bids and targeting. Using the same window for evaluation ensures consistency. For business decisions: Compare 7-day click (without view-through) to understand how much Meta's click-driven influence contributes. This reduces view-through inflation. For cross-channel comparison: When comparing Meta to Google, understand that Google typically uses last-click attribution and does not include view-through by default. Meta's view-through makes its ROAS look better than Google's by default. MHI Media's approach: Report using all three windows monthly. Flag large discrepancies between 7-day click+view vs 7-day click only as a signal to investigate view-through attribution impact.

FAQ

Should I use 7-day click or 1-day click as my primary Meta attribution?

Use 7-day click as your primary reporting window. It best captures the genuine consideration cycle for most DTC purchases. Use 1-day click as a check to understand immediate purchase intent performance, but do not set CPA/ROAS targets based on 1-day click as this will systematically undervalue Meta's contribution.

Does Meta's attribution window affect how my campaign is optimised?

Yes. Meta's algorithm uses the attribution window you set when deciding which users to target and how much to bid. If you change from 7-day to 1-day click attribution, the algorithm optimises toward users most likely to purchase within 1 day, which may restrict reach to high-intent immediate buyers and miss the broader consideration audience.

How does 7-day click attribution affect my CPA calculation?

Your CPA using 7-day click includes all purchases from users who clicked an ad in the preceding 7 days. This is broader than same-session conversions. For a brand with a typical 3-day consideration period, 7-day click attribution captures most genuine click-influenced purchases. Your true CPA may be slightly higher if some 7-day click conversions would have happened organically anyway.
