Attribution windows we support
How to choose the right window, and when to use multiple.
3 min read•Updated March 20, 2026
Attribution windows define "how long after a click/view does a conversion still count." Different windows produce different ROAS numbers for the same underlying data.
Supported windows
- 1-day click: aggressive, cuts out most assists.
- 7-day click, 1-day view: the Meta default; industry standard.
- 28-day click, 7-day view: catches long consideration cycles.
- 60-day click: useful for high-AOV, considered purchases.
- 90-day click: B2B SaaS, luxury goods.
Choosing
Match the window to your product's consideration cycle. Impulse consumer goods: 1-7 days. Considered consumer: 28 days. B2B, luxury, or subscription: 60-90 days.
Using multiple
Scale-plan customers can run the same campaign under two windows simultaneously (e.g., 7-day-click for operational decisions, 28-day for executive reporting). Omesta shows both numbers without forcing you to pick.
