Intero Digital releases guide for measuring real Amazon growth

Intero Digital has published a new guide for Amazon sellers on how to tell whether marketing is driving incremental sales or just getting credit for demand that already existed. The framework combines Amazon Attribution, conversion path reporting and Amazon Marketing Cloud to help brands separate real growth from attribution theater.

Why it matters: - Amazon sellers can meet return-on-ad-spend targets and still misread what is actually driving sales. - Better measurement helps brands shift budget toward channels that create incremental demand, not just last-click credit. - The guide is aimed at brands that want clearer decisions across off-Amazon and on-Amazon media.

What happened: - Intero Digital released a new guide titled "How to Use Amazon Attribution to Measure What’s Really Driving Sales." - The guide lays out a three-tool framework for Amazon measurement. - Intero Digital positioned the framework as a way to identify which channels are truly contributing to sales.

The details: - Amazon Attribution tracks off-Amazon marketing such as paid social, email and influencer campaigns by attaching tags to shared links and crediting purchases to the originating channel. - Conversion path reporting shows the sequence of on-Amazon ad touchpoints that precede a sale within a 30-day window. - Amazon Marketing Cloud, or AMC, combines Amazon advertising signals with first-party data to test incrementality and measure the full customer path to purchase. - The guide says Amazon Attribution uses a standard 14-day last-touch model. - Under that model, higher-consideration purchases can fall outside the attribution window and go unattributed. - The model gives full credit only to the most recent tagged click. - Earlier touchpoints can lose credit even when they helped create awareness. - Amazon Attribution tracks clicks only and does not include view-through attribution for impressions. - The tool also lacks cross-device tracking, so a mobile click and a desktop purchase may not connect. - Intero Digital cautions against using Amazon Attribution as the sole source of truth for off-Amazon channel decisions. - Conversion path reporting expanded to 29 countries as of November 2025. - The reporting shows how Amazon ad formats work together, rather than crediting only the format that closes the sale. - The main limitation is granularity. - The paths appear at the ad-type level, not at the keyword or campaign level. - AMC extends the attribution lookback window to 28 days. - After a CES 2025 update, AMC can query up to five years of Amazon purchase signals. - That longer history can help brands with longer sales cycles and seasonal products. - AMC requires SQL and either in-house technical resources or an experienced agency partner. - Intero Digital recommends starting with Amazon Attribution tagging across every off-Amazon channel. - The guide then advises collecting several months of clean data before using conversion path reporting and AMC to test incremental growth. - The guide is available on the Intero Digital website now.

Between the lines: - The framework reflects a shift away from optimization based on flattering attribution reports. - Intero Digital is pushing brands to evaluate whether spend creates new demand or simply captures demand that was already there. - The emphasis on multiple tools suggests no single Amazon measurement product fully answers the incrementality question.

What's next: - Brands using Amazon ads can apply the guide by tagging every off-Amazon channel first. - After enough data builds, teams can compare results across attribution, path reporting and AMC to find the channels that actually drive growth. - The full guide is available on the Intero Digital website.

The bottom line: - Intero Digital’s message is simple: strong Amazon ROAS is not the same thing as real growth.
