How Reddit attribution windows work
Default credit spans 28 days after clicks and 1 day after views. This guide explains the windows and when to lengthen them.
Reddit documented default web attribution is 28-day click-through plus 1-day view-through. Available window settings exist beyond the default, though exact Help Center publication metadata for the page is unverified, so confirm current options inside Ads Manager.
The defaults#
Twenty-eight days after a click, one day after a view: the standard credit span for web conversions. The defaults suit considered purchases with multi-day journeys and over-credit impulse buys judged daily. Know which business you are before changing them. Reference: web attribution help.
Research journeys run long#
Reddit own research finds view-attributed conversions plateauing around 10 days versus 3 for clicks, and partner analysis puts over 65 per cent of attributed conversions after the first week. Short windows systematically undercount Reddit-driven demand. Research: Reddit researchers study.
Test longer windows#
Compare default against extended windows on stable campaigns and watch credited volume plus CPA move. Longer windows suit research categories (software, finance, hardware, education); shorter windows suit impulse and event-driven offers. Never change windows mid-test: it rewrites history for every comparison running. View credit: view versus click.
Date assignment quirks#
Reddit attributes conversions to the ad view or click date while third parties typically use the conversion date, so raw totals never reconcile across systems without aligned rules. Align windows, align date logic, then compare; anything else compares weather across calendars. Mismatch guide: GA4 mismatch.
Windows are strategy#
Window choice declares a belief about the buying journey. Research-heavy B2B with 60-day cycles needs longer credit than the defaults comfortably give; pair extended windows with lift testing for the honest answer. Incrementality: conversion lift.
Putting window testing into practice#
Run the window comparison on one stable campaign this month: default versus extended, identical spans, CPA and volume deltas logged. Adopt the window that matches the buying journey, then freeze it across reporting so history stays comparable. Windows are infrastructure, not opinions.
Re-test windows when the mix shifts materially toward research categories or impulse offers. Stability with scheduled challenges. Method: view versus click and conversion lift.
