Start with the commercial outcome
Ecommerce PPC agencies manage both media and commercial data. Product feeds, conversion tracking, pricing, stock and margin can affect performance as much as bids or ad copy.
A high return on ad spend can still hide weak profit if margins differ sharply across products. Give the agency enough commercial context to understand which sales are genuinely valuable.

| Compare | Ask before signing |
|---|---|
| Feed | Who owns product titles, attributes and feed quality? |
| Campaign mix | How are Shopping, Performance Max and Search used together? |
| Tracking | Are purchase value and transaction data reliable? |
| Margin | Can the agency distinguish high-revenue from profitable products? |
| Stock | How are unavailable products handled? |
| Budget | What evidence justifies scaling spend? |
Make implementation responsibility explicit
Ask how feed improvements, campaign structure and landing-page issues are divided between the agency and your ecommerce team. Missing ownership can leave obvious problems unresolved.
List any work that depends on your developer, ecommerce team, sales team or another supplier. A good proposal should make those boundaries obvious before launch.
Agree the measurement model
Track cost, revenue and conversion rate, but also review product-level economics and new versus returning customer behaviour where available. Platform attribution should be checked against store data.
Decide which metrics are diagnostic and which ones determine whether the investment is commercially useful.
Protect account ownership and data
Keep appropriate business access to advertising, analytics, store and CRM accounts. Confirm what happens to campaigns, audiences, feeds, data and creative if the supplier changes.
Ask for proof that matches the service
Ask for a product-level reporting example and a clear process for feed, stock and conversion-tracking QA.
Where client data is confidential, the provider can still show redacted structures, workflow examples or implementation evidence without inventing results.

Frequently asked questions
How should I compare ecommerce paid search providers?
Compare scope, implementation, ownership, reporting, exclusions and the commercial outcome each proposal is expected to improve.
Should I choose the lowest fee?
Not automatically. Compare media, software, production, implementation and support costs that may sit outside the headline fee.
What should be agreed before launch?
Agree goals, responsibilities, access, tracking, approvals, budget boundaries and the conditions for scaling or changing direction.
What is a warning sign?
The agency reports only blended ROAS and cannot explain which products, campaigns or customer types are driving the result.
What proof should I request?
Ask for a product-level reporting example and a clear process for feed, stock and conversion-tracking QA.
