What Are Amazon Attribution Windows, and Why Are They Important?
Amazon attribution windows define how long a click or view can be linked to a purchase. Sponsored Products have a 7‑day click window, Sponsored Brands a 14‑day click window and a 1‑day view window, while Amazon DSP offers a 30‑day click window. Early same‑day data in Seller Central is provisional until these windows close.
Overview
Amazon’s attribution windows set the period during which a shopper’s click or impression can be linked to a later purchase, and the length of that period varies by ad format. For Sponsored Products the window can stretch up to seven days for clicks, while Sponsored Brands allow up to fourteen days; display campaigns managed through Amazon DSP enjoy a full thirty‑day click window. Sellers who ignore these timeframes risk making optimization decisions on incomplete data, which can erode ad efficiency and profitability.
Key Points
- Click‑attribution span for Sponsored Products — A purchase made within seven days after a shopper clicks a Sponsored Product ad is counted toward that click, giving sellers a week‑long window to capture conversion credit.
- Click‑attribution span for Sponsored Brands — Sponsored Brands extend the click credit period to fourteen days, so any sale occurring within two weeks of the click is attributed to the brand‑level ad.
- View‑attribution limitation — Both Sponsored Products and Sponsored Brands only assign a sale to an ad view if the purchase happens on the day following the impression, making view‑based credit a one‑day metric.
- Amazon DSP click window — Display ads served through Amazon DSP use a thirty‑day click window, allowing advertisers to track longer‑term influence from banner and video placements.
- Same‑day reporting caveat — While Seller Central shows same‑day performance numbers, those figures remain provisional until the relevant attribution window closes, meaning early data can under‑represent true sales.
- Premature optimization risk — Adjusting bids, budgets, or keywords before a window finishes may lead to decisions based on partial conversion data, potentially harming campaign momentum and ROI.
How Attribution Windows Work
- Click capture initiates — When a buyer clicks a Sponsored Product ad on March 3, Amazon opens a seven‑day click window, so any order of that SKU placed between March 3 and March 9 will be linked to the click.
- — If a shopper merely sees a Sponsored Brands banner on March 3 without clicking, a one‑day view window starts, and only a purchase completed on March 4 can be credited to that impression.
Analysis & Recommendations
Why This Matters
If sellers adjust bids or budgets before the attribution window ends, they may act on incomplete conversion data, leading to reduced ROAS. Waiting for the full 7‑day (SP), 14‑day (SB) or 30‑day (DSP) window ensures accurate performance metrics and smarter optimization.
Key Takeaways
- Sponsored Products attribute click sales for up to 7 days after the click.
- Sponsored Brands extend click attribution to 14 days, but view attribution only counts sales on the following day.
- Amazon DSP click window lasts 30 days, allowing long‑term influence tracking.
- Same‑day numbers in Seller Central are provisional; final figures appear only after the respective window closes.
Recommended Actions
- →In Seller Central > Advertising > Campaign Manager, wait the full click window (e.g., 7 days for SP) before changing bids; review the final sales c...
- →Schedule DSP performance reviews on the day the 30‑day window ends (e.g., May 31 for a May 1 launch) via the DSP console's reporting dashboard.
- →Combine view‑attributed sales (found under 'View‑attributed sales' in the performance report) with click data before making budget adjustments.
