Google Shopping Ads built on a feed that works
The short answer
Google Shopping performance is decided in the Merchant Center feed, not in the campaign. You cannot bid on keywords — Google matches queries to your product data. So your titles, attributes and images are your keyword strategy.
PMG rebuilds feeds for search relevance, segments products by margin so bidding reflects profitability, and keeps disapprovals and availability errors from silently removing your best sellers.
Feed optimisation, where the gains are
- Titles front-loaded with brand, product type and the attributes people actually search
- Product type and Google category mapped precisely, since they influence matching
- GTIN, MPN and brand populated, which improves eligibility and match quality
- Images clean and compliant — no watermarks, no promotional overlays
- Custom labels for margin tier, seasonality, bestseller and clearance status
- Availability and price synced frequently to avoid disapprovals and mismatch penalties
Campaign structure
- Segment by margin using custom labels, so high-margin products get aggressive bids and thin-margin ones don't.
- Separate bestsellers into their own campaign with their own budget — they'll otherwise be starved by the long tail.
- Use priority settings deliberately when running multiple Shopping campaigns alongside PMax.
- Apply negatives at campaign level; Shopping still matches queries you don't want.
- Monitor disapprovals weekly. A silently disapproved bestseller is expensive.
- Review impression share by product to find where budget is capping revenue.
Feed optimisation priorities
| Attribute | Why it matters | Best practice |
|---|---|---|
| Title | Main relevance signal | Brand + product type + key attributes (size, colour, material, pack) |
| Image | Drives click-through | Clean, high-resolution, product clearly visible |
| Price and availability | Must match landing page | Frequent feed updates |
| GTIN / MPN | Product matching and eligibility | Include wherever available |
| Product type and Google category | Structure and relevance | Accurate, specific categories |
| Custom labels | Campaign structure | Margin tier, bestseller, season, stock level |
How to structure Shopping campaigns
- By margin — high-margin products can afford higher bids.
- By performance — proven bestsellers separated from long-tail products.
- By category — distinct budgets for categories with different economics.
- By brand vs non-brand queries — where query-level control is available.
Common Merchant Center issues
- Price or availability on the site doesn't match the feed
- Missing or invalid GTINs
- Images with watermarks, text overlays or placeholder images
- Shipping and returns information missing
- Policy disapprovals for restricted products or claims
- Feed not updating after price changes during sales
Shopping by catalogue type
| Catalogue | Strategy | Key metric |
|---|---|---|
| Small (under 100 products) | Product-level structure, strong titles | ROAS by product |
| Large (thousands of products) | Segment by margin and performance | Profit by segment |
| Seasonal | Feed updates and promotion timing | Sell-through |
| High-ticket items | Strong images and reviews | Conversion rate |
A worked example
An electronics retailer's Shopping ads spent most of their budget on low-margin products. We added margin labels to the feed, split campaigns by margin band, improved titles with key specifications, and fixed Merchant Center disapprovals. Profit from Shopping rose even as revenue stayed similar.

Frequently asked questions
Why are our products disapproved?
Most commonly: price mismatches between the feed and landing page, missing GTINs, image policy violations, or missing required fields. Merchant Center diagnostics lists each reason.
Shopping campaigns or Performance Max?
Many accounts use both — PMax for breadth, standard Shopping for control over specific product groups. Understand the priority interaction before running them simultaneously.
How often should the feed refresh?
Daily at minimum. Use the Content API or a feed tool for near-real-time price and stock updates if your inventory moves fast.
What are free product listings?
Unpaid listings in Google's Shopping tab and other surfaces, powered by the same Merchant Center feed. They add visibility at no media cost.
How often should the product feed update?
At least daily, and more often during sales or when prices and stock change frequently.
Do Shopping ads work for high-value products?
Yes, for products people compare online — electronics, appliances, furniture, jewellery — with strong images and clear pricing.
Why are my products disapproved in Merchant Center?
Common causes include price or availability mismatches, missing identifiers, policy issues and image problems — the diagnostics page lists them.
Should we use Shopping or Performance Max?
Performance Max now drives most Shopping inventory; standard Shopping is still useful for control and testing.
Do free product listings help?
Yes — free listings can bring extra traffic once your Merchant Center feed is set up.
What identifiers do products need?
GTINs where they exist, plus brand and MPN where relevant.
Can services use Shopping ads?
No — Shopping ads are for physical products with feeds.
How long does Google Shopping Ads take to show results?
Tracking fixes and search campaigns often show improvement within two to four weeks; prospecting on Meta or YouTube usually needs three to six weeks of creative testing; SEO compounds over three to nine months. We agree leading indicators up front so progress is visible early.
Is there a long contract?
No. Minimum terms are short, because we would rather keep clients with results than with contracts.
Will we own the ad accounts and data?
Yes. Everything runs in your own accounts with partner access for PMG, and you can see it all at any time.
What do you need from us to start?
Access to ad accounts and analytics, your margins and order values (or deal values), brand assets, and a decision-maker available for a weekly 30-minute call.
