Business model: Marketplace Crossover
Google Ads for Marketplace Crossover Ecommerce Brands
Selling direct AND on marketplaces creates problems most agencies don't see. Your own brand competes with itself across channels. Amazon's algorithm bids on your brand terms. Buyers research on DTC and convert on Amazon. The blended Google Ads report attributes everything to direct, and your true DTC POAS quietly collapses.
JudeLuxe runs profit-led Google Ads for UK marketplace-crossover brands spending £15k+/month - across Amazon, eBay, TikTok Shop, Etsy, and Shopify direct. The methodology accounts for cross-channel cannibalisation, attribution leakage, and channel-pricing conflict. We don't pretend the marketplaces aren't there.
What makes marketplace-crossover different for ecommerce PPC.
Brand search is contested by your own marketplace listings
Amazon and eBay bid aggressively on branded terms - sometimes paying more for your brand than you do. If your DTC PPC isn't explicitly defending branded search, marketplace listings will win it, and you'll pay the marketplace commission on what should have been a direct sale.
Attribution leakage hides the real DTC contribution
Buyers research on DTC, abandon, and convert on Amazon. Google Ads attributes the click to DTC; the revenue lives on marketplace. POAS calculated only on direct revenue understates DTC's true contribution, which leads to underinvestment. Cross-channel attribution modelling is required, not optional.
Pricing parity rules constrain promotional bidding
Amazon's pricing parity policy means your DTC store can't price below your Amazon listing without retaliation. PPC promotional bidding (cashback, first-order discounts, free shipping thresholds) needs to stay inside parity rules - or live in audience-gated promotions that aren't visible to the marketplace.
Marketplace fulfilment changes basket economics
Amazon FBA fees, marketplace commissions, and split fulfilment (some SKUs DTC, others marketplace-only) reshape contribution margin per channel. POAS measured on blended channel revenue obscures the truth - you need POAS measured separately on each channel, with budget flowing to the higher-margin channel per SKU.
How JudeLuxe runs Google Ads for marketplace-crossover brands.
BOI® job assignment runs across both channels for crossover accounts. Scale SKUs are typically split - high-margin SKUs scale on DTC where margin is best protected, low-margin volume drivers scale on marketplace where Amazon's CPC is lower. Profit jobs almost always run DTC-only (full margin retention). Protect runs DTC for brand defence. Recovery often runs marketplace-only (clear inventory through Amazon FBA). Gateway typically runs through DTC, with the marketplace handling re-purchase.
The Five Rounds rhythm adds a Wednesday cross-channel reconciliation: blended POAS per SKU, channel-specific POAS per SKU, and channel reallocation decisions logged for the week ahead.
FAQs
Should I bid on my own brand terms if I'm also on Amazon and eBay?
Yes - defensively. Marketplace listings bid aggressively on branded search, and if you don't defend the term, you'll pay marketplace commission on what should have been direct sales. JudeLuxe runs branded suppression on marketplace-listed SKUs and aggressive defensive bidding on DTC-only SKUs, calibrated to the marketplace commission you're avoiding.
How do you handle attribution between Google Ads and Amazon Marketplace conversions?
Google Ads attribution captures the click, but the conversion often happens on Amazon. JudeLuxe runs cross-channel attribution modelling that includes marketplace orders in the DTC POAS calculation, with conversion values adjusted for marketplace commission. The honest number sits 20–40% above the platform-reported DTC POAS for most crossover brands.
Can I price below Amazon on my DTC store using Google Ads promotions?
Not openly. Amazon's pricing parity policy will retaliate. JudeLuxe runs promotional bidding through audience-gated channels (returning-customer offers, email subscribers, cart abandoners) that aren't visible to Amazon's price-monitoring systems.
What's the minimum spend for retained marketplace-crossover PPC management?
£15k+/month on Google Ads. Crossover brands at this tier typically run £20k–£200k/month with separate budget envelopes for DTC and marketplace-defence. Below £15k/month, the free audit is the better starting point.
