The Client

We Love Eyes is a clinician-founded eye-care DTC brand selling oil-free cleansers and lid-care products through both their own site and Amazon. The brand had real product-market fit but was running paid media on each channel in a silo.

Challenge

What was broken.

The Amazon-plus-DTC combo is a common attribution trap. Google Ads gets credit for clicks that ultimately converted on Amazon, but Amazon converts because the buyer remembered the Google ad, so cutting Google would tank Amazon. Conversely, scaling Amazon Ads can pull customers off the brand site, which wrecks DTC margin.

We Love Eyes was running both channels but couldn't tell where Amazon was eating Google credit, where Google was actually driving Amazon orders, and where the two channels were just bidding against each other on the same query.

What we did

The plays we ran.

Built a cross-channel attribution model that tracked Google → Amazon assist conversions, not just last-click

Rebalanced spend to true incrementality, pulled budget from queries where Amazon was already winning organically

Segmented Amazon Sponsored Products by stage: defense on brand terms, offense on category terms

Aligned Google Shopping feed to match Amazon top-sellers so we weren't pushing buyers to OOS or low-margin SKUs

Coordinated Meta retargeting to push high-LTV repeat buyers to DTC, low-intent first-time buyers to Amazon

Set up shared reporting so Amazon and Google budgets moved together, not in isolation

Results

The numbers.

Blended ROAS hit 10x across the combined channel mix. Amazon orders grew 340% as the assist-conversion picture clarified what was actually driving them. Blended customer-acquisition cost dropped 28% because we stopped paying twice for the same buyer.

The core insight: Amazon and Google weren't two channels, they were one funnel that needed to be managed as a single P&L.
