The Omnichannel Reality of Linear TV

For consumer brands selling on both direct-to-consumer (DTC) websites and Amazon, 30% to 50% of TV-stimulated consumer interest navigates directly to Amazon rather than visiting the brand's URL.

Attribution models that only measure Google Analytics 4 suffer from severe blind spots:

1. Understated Campaign ROI: Offline broadcast media gets under-credited because marketplace sales are unaccounted for.
2. Penalized Daytime & Weekend Flights: Daytime and weekend airings often drive mobile Amazon app searches rather than immediate desktop web sessions.
3. PPC Budget Drain: TV-stimulated shoppers searching for the brand on Amazon are often intercepted by internal Sponsored Brands campaigns, inflating paid search costs.

Dual-Stage Amazon Response Dynamics

Unlike web sessions that spike within 120 seconds of broadcast, Amazon response exhibits a dual-stage temporal curve:

Web Visits (GA4):    [Spike: 1-6 min] ──────────► Back to baseline
Amazon Search:       [Impulse: 0-2 hours] ──────► Search halo
Amazon Purchases:    [Lagged peak: 4-36 hours] ─► Multi-day retail halo

• Stage 1 — Immediate Intent (0 to 2 hours): Branded search query volume and Product Detail Page (PDP) glance views surge on Amazon.
• Stage 2 — Delayed Conversion (4 to 36 hours): Purchases and ordered units peak several hours later as consumers compare variants, add items to cart, and checkout upon returning home.

What SpotLift Pro Unlocks for Amazon

Upgrading to SpotLift Pro provides complete, turnkey Amazon measurement without needing to write custom clean-room pipelines:

1. Curated AMC Clean Room SQL Suite

SpotLift Pro includes tested, production-grade Amazon Marketing Cloud (AMC) queries designed to extract:

• Hourly ordered units and gross merchandise value (GMV).
• New-to-Brand (NTB) purchase share stimulated by broadcast flights.
• Brand search impressions and detail page view surges.

2. 36-Hour Distributed Lag Convolution

Applies econometric distributed lag models across hourly Amazon conversion streams, estimating the exact total sales multiplier generated per television rating point (GRP).

3. Sponsored Brands PPC Cannibalization Audit

Automatically measures the Cannibalization Index:

• Identifies hours where TV-stimulated organic shoppers clicked on expensive internal Sponsored Brands or Sponsored Products ads.
• Recommends exact daypart bidding reductions to prevent wasting PPC budget on consumers who were already planning to purchase.

Running Omnichannel Attribution in SpotLift Pro

With SpotLift Pro, you pass both GA4 web telemetry and Amazon AMC telemetry into a unified attribution pipeline:

import spotlift

airings = spotlift.load_airings("tv_schedule.csv")
web_telemetry = spotlift.load_telemetry("ga4_sessions.csv")
amz_telemetry = spotlift.load_telemetry("amc_hourly_units.csv")

# Run omnichannel attribution in SpotLift Pro
report = spotlift.analyze_omnichannel_pro(
    airings=airings,
    web_telemetry=web_telemetry,
    amazon_telemetry=amz_telemetry,
    window_minutes=6,
    export_excel="omnichannel_audit_q4.xlsx"
)

# Access omnichannel summaries
print("Total Web Lift:", report["web_lift"])
print("Amazon Units Halo:", report["amazon_halo_summary"]["incremental_units"])
print("PPC Cannibalization Share:", report["cannibalization_summary"]["cannibalized_cost"])
