Google Shopping & Performance Max Management

For an online merchant with products and fulfilment in place

Your catalogue may be ready to advertise, already running with unresolved product issues, or producing reported revenue that does not answer a profitability question. Review inventory, product detail pages, delivery terms and purchase measurement before selecting a campaign type.

We can scope Merchant Center diagnostics and feed improvements, a defined campaign setup, or continuing optimisation. Existing business accounts and platform integrations should be inspected before recommending a new feed system or custom connection.

Product data and campaign management belong together

• Catalogue review: establish stable product and variant identity, accurate attributes and a supported update path. Inspect eligibility and prioritise issues affecting commercially important products.
• Landing-page consistency: check the selected variant, price, availability and delivery information a shopper sees after clicking.
• Campaign choice: compare Standard Shopping and Performance Max against the intended inventory, available assets, measurement and control requirements.
• Commercial grouping: identify product groups the owner can manage using stock, economics and merchandising priorities, rather than multiplying campaigns without a useful decision.
• Purchase signals: check order value, currency, duplicate purchase handling and the reporting boundary before optimising around attributed revenue.

Google's product-data guidance describes accurate, current data and consistency with landing pages. Read our feed prioritisation guide for a practical review sequence.

Start with an inventory and measurement baseline

1. Identify the first product range, target market, fulfilment constraints and commercial owner.
2. Review the feed source, Merchant Center status, update timing and product destination.
3. Check purchase measurement against permitted test orders and owner records.
4. Propose the campaign, asset and product-data changes with approval and recovery steps.
5. Review product-level outcomes and unresolved limitations before expanding coverage or budget.

Performance Max can use multiple Google advertising surfaces. It should not be treated as a guaranteed improvement over an existing Shopping campaign. For a comparison, consider a supported campaign experiment with comparable settings. Our campaign-type decision guide explains the evaluation boundary.

Measure commercial usefulness, not only product clicks

A hypothetical high-revenue product can still be a poor acquisition target when fulfilment costs, returns or unavailable variants undermine its contribution. Start with the owner's agreed economics. Keep attributed revenue, net sales and profit as separate measures, and explain what product costs are excluded from any dashboard.

Media spend, feed tooling, implementation and management fees are separate. Merchant eligibility and policy decisions remain with the platform. We do not promise approvals, sales or a target ROAS. If products receive relevant visits but buyers cannot complete a purchase, the next intervention may be e-commerce CRO rather than a campaign rebuild.

Buyer questions

Do Shopping and Performance Max need separate service engagements?

They can share one retail advertising scope because product data, purchase measurement and merchandising overlap. The campaign choice and specific deliverables are still agreed separately.

Can you guarantee Merchant Center approval?

No. We can investigate product-data and destination issues and implement agreed corrections. Approval and policy enforcement remain with Google.

Will Performance Max always outperform Standard Shopping?

No. Compare the inventory, objectives, assets, controls and actual commercial results. Use an appropriate experiment when feasible rather than assuming that a campaign-type change causes growth.
