Amazon’s ad ecosystem keeps growing. The two campaigns most sellers run from day one are Sponsored Products and Sponsored Brands. They look similar in the ad console, target similar audiences, and report through similar APIs. The data behind them is not the same, and confusing the two is the easiest way to misread your ad performance.

This guide explains the differences and how to use each properly.

TL;DR: Sponsored Products promote single ASINs in search results and product pages — attribution is direct, ACoS is the natural metric. Sponsored Brands promote your brand and a set of products through banner ads above search — attribution is broader and ROAS depends on multiple SKUs converting. They report through Amazon Ads API but have different metric definitions, click-attribution windows and creative structures. Reading them like-for-like is the first mistake.

What Sponsored Products do

Sponsored Products are pay-per-click ads that promote individual ASINs. They appear in search results, on competitor product pages and across Amazon’s rest-of-search inventory.

What the data looks like

• Direct attribution — click leads to that specific ASIN’s product page.
• Conversion windows are typically 7 days for SP campaigns.
• Performance metrics: impressions, clicks, CPC, attributed sales, ACoS, ROAS.
• Available at keyword, ad-group and campaign level.

Best for

• New product launches — driving discovery.
• Long-tail keyword expansion.
• Top-of-funnel discovery in your category.
• Brand-defense bidding on your own brand terms.

What Sponsored Brands do

Sponsored Brands are banner-style ads that promote your brand alongside a curated set of products. They appear above search results, in middle-of-search positions and at the bottom of search.

What the data looks like

• Attribution is broader — a customer can click on the banner and end up on a brand store, a product detail page, or a custom landing page.
• Conversions can attribute to multiple ASINs in the campaign.
• New-to-brand metrics distinguish first-time customers from repeat buyers.
• Available at campaign, ad-group and creative level.

Best for

• Brand awareness and brand search defense.
• Driving traffic to a Brand Store.
• Cross-selling across multiple ASINs in a portfolio.
• New-to-brand customer acquisition.

Where the data differs

Attribution

SP attributes one click to one ASIN. SB can attribute to multiple ASINs from one click.

Conversion windows

SP typically uses 7-day windows. SB has both 14-day and 7-day for different metrics. New-to-brand has its own attribution logic.

Cost structure

SP is straightforward CPC. SB also charges CPC but with more variability based on placement and creative.

Reporting cadence

SP reports refresh more frequently than SB. SB reports may have additional lag for new-to-brand metrics.

How to compare them properly

Comparing SP vs SB on raw ACoS is misleading because they target different parts of the funnel. The fair comparison requires:

• Holding category and audience constant where possible.
• Looking at TACoS rather than just ACoS — SB drives organic halo more visibly than SP.
• Including new-to-brand attribution for SB campaigns.
• Comparing time-windowed performance, not all-time.

Common mistakes

• Killing SB based on ACoS alone. SB is meant to drive brand reach. ACoS will be higher than SP — that is by design.
• Ignoring new-to-brand metrics. SB is the only campaign type that surfaces new-to-brand cleanly. Skipping it means missing the strongest signal of brand growth.
• Using one keyword strategy across both. SP rewards long-tail expansion. SB rewards branded and category-defining terms.

The bottom line

Sponsored Products and Sponsored Brands are different campaigns serving different goals. Reading them through the same metric lens loses information. Real ads optimization tracks both as separate streams against the same business outcomes.
