Two Amazon Ads Deep-Dive reports compared — SKU & campaign movement, ACOS/TACOS/ROAS trend.

Step 1 — The two reports to compare

These are reports this portal already generated — not files downloaded from the marketplace.

FILE 01

Two Amazon Ads Deep-Dive reports (.xlsx) (multiple: select both together)

IMPORTANT: this tool compares two reports THIS portal already generated with "Amazon Ads Deep-Dive" — it does NOT take raw files from Amazon Seller Central. Upload the LAST TWO MONTHS' generated reports (e.g. amazon-ads-deep-dive_Apr_2026.xlsx + amazon-ads-deep-dive_May_2026.xlsx) for the SAME account. Upload order does not matter — the tool detects which month is prior vs current and fixes the order automatically. Don't have them yet? Run Amazon Ads Deep-Dive for each month first, then come back here.
