Amazon’s Holiday 2026 post: fulfillment surcharge 15 Oct 2026–14 Jan 2027. Storage is a separate Oct–Dec window. Recalculate break-even ACOS before you raise Q4 bids.
Read the ブリーフ →About Amazon: Prime Big Deal Days 6–7 Oct 2026. Holiday inbound for that badge was posted as 2 / 9 / 16 September (AWD / minimal / optimized). Ads follow inventory, not the press page.
Read the ブリーフ →Rufus was folded into Alexa for Shopping on the US app and site. The assistant reads titles, bullets, A+, Q&A, and reviews. Incomplete listings get skipped in the answer, not just buried in the grid.
Read the ブリーフ →Children’s products, cosmetics, ingestibles, and lithium-battery goods need $1 million commercial liability regardless of GMV. Mainland China sellers must use Amazon Insurance Accelerator for new policies.
Read the ブリーフ →The 2026 US FBA change was not a surprise September table. Fulfillment rose ~$0.08/unit on 15 Jan, a 3.5% fuel/logistics surcharge hit 17 Apr, and peak fulfillment runs 15 Oct 2026–14 Jan 2027. Recalculate contribution before you raise Q4 bids.
Read the ブリーフ →Cancellation, late shipment, ODR, and on-time delivery failures now deactivate the offer — not the whole account. Better for Account Health. Worse for the ASINs you are advertising.
Read the ブリーフ →Measurement and Reporting → Reporting is the new console. Amazon is sunsetting the old Sponsored Ads reports and DSP reports by 31 Dec 2026. Recreate scheduled exports before they die.
Read the ブリーフ →Prime Day 2026 moved to a four-day June window (23–26 Jun, 12:01 a.m. PDT). AWD/minimal-split inbound 27 May; Amazon-optimized splits 5 Jun. Ads into stock that missed check-in is a write-off.
Read the ブリーフ →A 3.5% surcharge on US (and Canada) FBA fulfillment fees from 17 April 2026. It sits on top of the 15 January rate card. January PDFs are stale.
Read the ブリーフ →The Business Solutions Agreement grew formal requirements for AI agents and automated systems. Your bid robot is still your problem. Unsupervised “max ROAS” on a blend is still a leak.
Read the ブリーフ →Amazon-optimized inbound splits can zero placement fees. Minimal split is convenience you pay per unit. Placement is a bid input — it changes contribution before a click happens.
Read the ブリーフ →Low-inventory level fees expanded to FNSKU-level and bulky in the January 2026 US fee window. A parent with one empty size still pays on that child. Restock or stop ranking ads into the surcharge.
Read the ブリーフ →Amazon’s 2026 US FBA notice: average fulfillment +$0.08 per unit from 15 January, more price bands, low-inventory at FNSKU, no new fee types. 2025 had no US Referral/FBA increase.
Read the ブリーフ →Amazon retired the blind 14-day in-store view-through window on 1 Jan 2026 for eligible DSP, SB, and SD placements. Click attribution unchanged. DSP ROAS looking “worse” is often the model, not the funnel.
Read the ブリーフ →Amazon Marketing Cloud became available inside the Ads Console for Sponsored Products / Brands / Display without a DSP relationship. Overlap and NTB stopped being a partner-only hobby.
