"Really recommend Clean Digital, they've been a fantastic agency to work with and we've always been really impressed with the team and the results they produce."
Google Shopping and Performance Max can only work with the product data they receive. We improve the feed, Merchant Center diagnostics and product signals that decide eligibility, traffic quality and budget allocation.
Once the feed is ready, we can also review whether Gander, Clean Digital's Comparison Shopping Service, is suitable for the account.
Titles, attributes, categories, stock and landing pages shape the auctions your products enter. Feed work is campaign work.
Feed optimisation starts with the source of the data. A Merchant Center rule can correct an output, but it can also hide a recurring catalogue problem. We document the full path before deciding where a change belongs.
Product IDs, variants, prices, availability, images and destination URLs begin in the store or product system.
An app, scheduled file, API connection or feed platform sends the catalogue to Merchant Center.
Google validates product identity, policy, price, stock, shipping and landing-page consistency.
Approved products enter Shopping or Performance Max with product groups that can be measured and controlled.
The work depends on the catalogue and product category. These are the controls that most often affect product identity, eligibility, search matching and the ability to manage spend by commercial priority.
| Feed area | What we check and change | Why it matters |
|---|---|---|
| Product identity | Keep item IDs stable and supply valid brand, GTIN or MPN data where those identifiers exist. | Preserves performance history and helps Google identify the exact product being sold. |
| Titles and descriptions | Put the product type and useful differentiators in a readable order based on real search language. | Improves the information Google can use when matching a product to a search. |
| Classification | Use accurate Google product categories, product types and required category-specific attributes. | Reduces ambiguity and supports cleaner campaign reporting by product group. |
| Price and availability | Synchronise price, sale price, currency, stock and condition with the landing page. | Reduces avoidable mismatches and prevents spend from being directed to unavailable products. |
| Images and landing pages | Check image eligibility, variant links, mobile pages, redirects and the product information shown after the click. | Protects approval and gives the shopper a consistent route from ad to product. |
| Custom labels | Add margin, stock, season, price band, bestseller or business-priority labels from reliable source data. | Allows campaigns and reports to separate products that need different budgets or targets. |
Merchant Center warnings are the start of the diagnosis. The commercial effect depends on which products are affected, whether they receive spend and whether the issue returns after the next catalogue update.
Each change needs an owner, a source and a validation step. This keeps the feed maintainable after the immediate Merchant Center issue has been cleared.
We identify which system owns every important field and how changes reach Merchant Center. This prevents feed rules from hiding an upstream data problem.
Diagnostics are grouped by affected products, revenue potential and campaign spend. High-value catalogue gaps are handled before cosmetic warnings.
Changes are made at the source where possible. Merchant Center approval, landing pages and item counts are checked after the next successful update.
Title changes, labels and campaign groupings are evaluated against an appropriate comparison so the team can see whether the feed work changed useful traffic and sales.
A lower warning count is useful, but it is not the complete result. We connect feed health to item-level traffic, campaign spend and sales so the business can decide which changes are worth keeping.
See our paid media measurement serviceA technically healthy feed cannot correct weak pricing, low stock, an unsuitable landing page or inaccurate purchase tracking. It also cannot repair a campaign that pools products with very different economics under one target.
We separate feed fixes from campaign, analytics and commercial issues in the initial review. The proposed scope then covers only the work needed to change the result.
Dobbies required paid media to respond to seasonal retail demand across online sales and more than 70 stores. The case study shows how paid search, paid social and analytics were coordinated around commercial results.
Read the Dobbies case studyFeed work can be delivered as part of Shopping management or alongside a wider ecommerce PPC programme. The right scope depends on whether product data, campaign control or measurement is the main constraint.
We will review the feed source, Merchant Center diagnostics and product-level campaign data, then explain which fixes are likely to change eligibility, traffic quality or budget control.
