Reddit Ads Attribution: Understanding Your Data

Reddit ads attribution determines how conversions get credited to your advertising. Understanding attribution is essential for accurate ROI measurement and informed budget decisions. Misconfigure attribution, and you'll either undercount your results or overclaim performance.

This guide explains how Reddit's attribution works and how to configure it for your business.

What Is Attribution?

Attribution connects conversions (purchases, sign-ups, leads) back to the ad interactions that influenced them. When someone converts on your website, attribution answers: which ad deserves credit?

Reddit tracks two types of interactions:

• Clicks: User clicked on your ad
• Views: User saw your ad but didn't click

Attribution windows define how long after these interactions a conversion can be credited.

Reddit's Attribution Model

Reddit uses last-touch attribution with configurable windows:

Last-Touch Attribution

The last Reddit ad interaction before conversion receives credit. If a user clicked Ad A, then clicked Ad B, then converted—Ad B gets the conversion.

This model is:

• Simple to understand: One ad = one conversion
• Action-biased: Rewards ads that drive clicks
• Limited in scope: Doesn't credit earlier touchpoints

Attribution Windows

Reddit offers configurable windows for both click and view attribution:

Click-Through Windows:

• 1 day
• 7 days (default)
• 14 days
• 28 days

View-Through Windows:

• 1 day (default)
• 7 days
• Off (no view-through attribution)

A 7-day click / 1-day view window means: credit conversions that happen within 7 days of a click or 1 day of a view.

Configuring Attribution Windows

Access Attribution Settings

1. Navigate to Events Manager in Reddit Ads Manager
2. Select your Conversion Action
3. Click Edit to modify attribution settings
4. Set click-through and view-through windows
5. Save changes

Choosing Click Windows

Short windows (1-7 days):

• Best for impulse purchases, low-consideration products
• More conservative measurement
• May undercount B2B and high-value conversions

Long windows (14-28 days):

• Best for B2B, enterprise sales, considered purchases
• Captures extended decision cycles
• May include less directly-influenced conversions

Guideline: Match your window to your typical sales cycle. If customers research for weeks before buying, use longer windows.

Choosing View Windows

1-day view:

• Conservative approach
• Credits conversions very close to ad exposure
• Industry standard for most advertisers

7-day view:

• More inclusive
• Captures delayed impact of awareness
• May inflate numbers for some advertisers

No view-through:

• Most conservative
• Only credits clicked conversions
• Useful when view data seems unreliable

Guideline: Start with 1-day view. Only extend if you have evidence that view-through conversions represent genuine ad impact.

Attribution Challenges

Cross-Device Gaps

Users may see ads on mobile but convert on desktop. Reddit can't always connect these journeys, leading to uncounted conversions.

Mitigation:

• Encourage logged-in user journeys
• Use longer attribution windows
• Supplement with server-side tracking

Multi-Touch Reality

Real customer journeys involve multiple touchpoints across channels. A user might see a Reddit ad, click a Google ad, and convert through an email link. Last-touch only credits email.

Mitigation:

• Use multi-touch attribution tools (separate from Reddit)
• Conduct incrementality tests to measure true lift
• Don't over-optimize based on last-touch alone

View-Through Controversy

Did a user convert because they saw your ad, or did they see your ad and happen to convert anyway? View-through attribution doesn't distinguish causation from correlation.

Mitigation:

• Use short view windows (1 day)
• Compare view-through conversions against baseline
• Run holdout tests to validate view impact

Attribution Delays

Conversion data may lag 24-48 hours in Reddit's reporting. Making optimization decisions on same-day data leads to errors.

Mitigation:

• Wait 48+ hours before evaluating conversion performance
• Use 3-day rolling averages for trend analysis
• Don't pause campaigns based on single-day conversion dips

Attribution Best Practices

Match Windows to Sales Cycles

E-commerce (low consideration):

• 7-day click, 1-day view
• Matches typical impulse and considered purchase behavior

E-commerce (high consideration):

• 14-day click, 1-day view
• Captures research periods for expensive items

B2B/SaaS:

• 28-day click, 7-day view
• Essential for capturing enterprise decision cycles

Lead generation:

• 14-28 day click, 1-day view
• Accounts for research before form submission

Stay Consistent

Use consistent attribution windows across all conversion actions. Mixing 7-day and 28-day windows makes campaign comparison meaningless.

Document Your Settings

Record your attribution configuration. When comparing to previous periods or external benchmarks, window differences explain apparent performance changes.

Validate with Backend Data

Compare Reddit-attributed conversions to your actual backend records:

• Do conversion counts roughly align?
• Is revenue per conversion accurate?
• Are transaction IDs matching?

Significant mismatches indicate tracking issues, not attribution problems.

Beyond Last-Touch Attribution

Incrementality Testing

The gold standard for measuring true ad impact. Run controlled experiments where some audiences see ads and matched audiences don't. Compare conversion rates to isolate ad-driven lift.

Reddit supports incrementality testing for larger advertisers through their measurement partners.

Multi-Touch Attribution Platforms

Third-party platforms like Northbeam, Triple Whale, or Rockerbox provide cross-channel, multi-touch attribution. They credit multiple touchpoints in the customer journey rather than just the last.

These platforms reveal Reddit's role in the full funnel—even when Google or email gets last-touch credit.

Marketing Mix Modeling (MMM)

Statistical analysis of how marketing channels drive business outcomes over time. MMM captures effects that pixel-based attribution misses, including brand impact and offline influence.

Particularly valuable for brands spending significantly across multiple channels.

FAQs

What attribution window should I use for B2B?

Use 28-day click and 7-day view for B2B advertising. B2B purchase decisions typically involve multiple stakeholders and extended evaluation periods. Shorter windows undercount conversions that Reddit influenced early in the decision process. Some B2B advertisers report 30-60 day windows would be more accurate for enterprise sales.

How do I know if view-through conversions are real?

Run holdout tests where matched audiences don't see ads. Compare their conversion rates to exposed audiences. The difference represents true view-through impact. Without testing, view-through conversions may reflect coincidental timing rather than ad influence.

Can I change attribution windows after campaigns run?

Changes apply to new conversions only. Historical data retains its original attribution. If you change from 7-day to 28-day windows, past conversions won't be recalculated. For consistent reporting, maintain the same windows throughout campaigns.
