Google Merchant Center guide
Last updated:
A Google Merchant Center Excellence report can reveal valuable opportunities across your product catalogue. The key is turning Google’s account-wide recommendations into a commercially prioritised plan.
The MEX workflow
There is little value in improving click-through rate on products that are disapproved, or enriching products that are not targeted by campaigns. Work through the funnel in sequence, then prioritise the products that matter commercially.
Make eligible products available across Shopping ads, free listings and Local Inventory Ads.
2Find and fix disapprovals affecting commercially important, high-demand products first.
3Submit broadly to Merchant Center, then control paid investment with campaigns and labels.
4Assess visibility by category, then fix the product data limiting relevant reach.
5Combine visibility, offer strength and relevance to earn more profitable clicks.
6Use product feeds selectively to remarket, create demand and grow priority ranges.
Before you start
Google’s job is to identify more opportunities to show your products, unlock demand and encourage more advertising investment. Your job is to sell more products at a margin that works for your business.
Understanding the score
The report may begin with a score and an offer funnel covering approved, in-stock and targeted products, plus products receiving impressions and clicks. It is a useful summary of the measures in the report, but it is not an official Google Ads or Merchant Center performance score.
Useful summary, not an official Google Ads or Merchant Center score.
Recommendations and status
The report may highlight Local Inventory Ads, price and availability mismatches, local offer eligibility, approvals, impressions or click-through rate. Treat these as areas to investigate rather than instructions to follow blindly.
Start with the products involved, then decide whether the opportunity is meaningful enough to pursue.
What the status column means
Red does not necessarily mean there is a serious business problem, and green does not mean there is no opportunity.
How to use the Action Items tab
Review Google’s high-priority items.
Identify the affected products.
Check whether those products matter commercially.
Group them by category, product type, brand, campaign or custom label.
Fix the highest-value opportunities first.
Recheck results after the changes have flowed through.
Stage 1
Make more of your products available across Google’s shopping surfaces. In Merchant Center, an “offer” is an individual product listing supplied through your Google Shopping feed that Google can review, match and potentially show to shoppers. Maximising total offers means ensuring that as much of your relevant catalogue as possible is eligible to appear wherever customers search and discover products.

Availability before advertising
The objective is not simply to submit more products. It is to make the right products available in the right places, with accurate pricing, availability, imagery and optimised product information.
A larger catalogue does not automatically create better results. Products still need to be approved, in stock, relevant to your customers and commercially worthwhile to promote.
Stage 2
Disapproved products and Merchant Center errors can prevent impressions or clicks, so approval is one of the foundations of product-feed performance. But not every disapproved product deserves the same level of effort.
Identify which products are disapproved and why.
Check demand, margin, stock, campaigns and strategic importance.
Restore high-value opportunities before broad catalogue cleanup.
Common approval issues
Price or availability mismatches
Invalid GTINs, missing attributes or poor imagery
Landing-page access, structured data or shipping
Missing or inconsistent store availability data
The most common approval issues
Price and availability mismatches often occur when the website updates before the feed, inventory systems are not synchronised or sale prices change without the product data being refreshed.
Automatic item updates can correct occasional differences, but they are a safety net—not a substitute for reliable, frequent feed updates.
Invalid GTINs should be corrected where possible. If an identifier is unavailable or uncertain, it is safer to omit it than submit an incorrect one.
Generic images, promotional overlays and placeholder images can also lead to disapprovals or reduced visibility. Replace them with genuine, accurate product imagery, prioritising high-value products first.
Shipping information, structured data and local inventory must also match what customers see on the website and in stores.
Stage 3
A product can be approved, in stock and eligible to appear on Google, but still be excluded from active advertising campaigns. That does not mean it should be removed from Merchant Center.
Eligible products can remain available across Google Shopping free listings, Search, Images, Lens and other unpaid surfaces.
Use campaigns, product groups and custom labels to direct investment towards the right products.
A product does not need paid campaign coverage to benefit from being discoverable through free or organic listings.
Control advertising with custom labels
Labels can include or exclude products from Google Shopping campaigns without removing them from Merchant Center—and can update dynamically as the business changes.
The commercial question
“Are these products deliberately excluded, or have they simply been missed?”
There may be good reasons not to advertise every product. Low margin, unreliable stock, poor conversion, high return rates or unsuitable delivery costs may not justify paid investment.
But important products that are approved, in stock and receiving no advertising activity may represent a missed opportunity.
Stage 4
Impressions are a useful north-star metric because they show whether Google is finding opportunities to display your products. But impressions alone are not enough: the goal is relevant visibility for the products and categories that matter.
How often products can appear
Whether listings earn attention
How visibility is distributed
Reach that can create value
A catalogue can have high total impressions while visibility is concentrated in very few products. A product can also earn impressions but few clicks, signalling that its title, image, price or relevance needs attention.
Find the limiting lever
The FeedOps audit helps connect visibility patterns to practical actions.
Run the free auditCategory-aware assessments and fixes
The MEX report may identify gaps across brand, GTIN, descriptions, titles, product highlights, colour, age group, gender, size and imagery. FeedOps applies category-aware logic so an account-wide percentage does not create irrelevant work.
Size · colour · material · gender · age group
Colour · material · dimensions · style · room
Brand · model · compatibility · specifications
Capacity · dimensions · energy rating · functions
Size · skill level · activity · material · features
Shade · skin or hair type · formulation · ingredients
Titles and descriptions
Put the most important information early, stay accurate and avoid applying one title formula indiscriminately across shoes, televisions, sofas and car parts.
A strong Google Shopping product title helps Google understand the product and helps the shopper decide whether it is relevant. Descriptions should add useful detail rather than repeat generic marketing language.
Product data for AI and agentic commerce
Large language models, AI Overviews and agentic shopping experiences rely on the same clear product information that supports the Google Shopping Graph.
Stage 5
Click-through rate shows whether shoppers choose your product after seeing it. But a higher CTR is only valuable when it creates profitable traffic and sales.
Make the listing noticeable.
Give shoppers a compelling reason.
Match what the shopper actually wants.
Traffic with a realistic chance of converting.
Visibility and attention
Local Inventory Ads, Merchant Promotions, sale-price and price-drop annotations, shipping signals, ratings and strong imagery can all draw the eye.
The strength of the offer
Competitive pricing matters, but value can also come from delivery speed, service, availability, returns, ratings and a complete proposition.
Price · sale price · promotions · shipping · availability · delivery certainty · returns · ratings · local availability
A promotion that raises CTR but destroys margin is not a successful result. Free shipping can help conversion while creating unacceptable fulfilment costs.
Use promotions to clear stock, grow a priority category, support peak trading, increase order value, move shoppers to a higher-margin product or compete for an important search. Ensure product data accurately reflects every promise.
If ratings are missing, investigate technical eligibility, review-feed integration, product matching, volume, market eligibility and seller-rating requirements. The issue may be technical, operational or simply insufficient review volume.
Relevance
A listing can have strong ratings and a promotion, but shoppers will not click if it is not the product they want. Relevance is where business control is greatest.
Fashion needs size, colour, material and pattern. A camera lens needs mount, focal length and compatibility. A car part needs make, model, year and fitment. Furniture needs dimensions, material, colour and room type.
Stage 6
Demand Gen can introduce products across YouTube, Discover and Gmail before shoppers actively search. With a Merchant Center feed, it becomes a browsable, visual storefront—but the objective is still to sell selected products, not pursue awareness without a commercial purpose.
Product advertising, prospecting and dynamic remarketing across Google inventory.
Shopping placements without the same built-in dynamic remarketing setup.
Personalised product ads based on items previous visitors viewed.
Visual feed formats that help selected products earn attention before direct search.
Create demand deliberately
Performance Max delivery is shaped by bidding, budget and target ROAS. A high target can restrict exploratory activity for products with limited conversion history or a longer consideration cycle.
Choose products selectively
Match product selection to the audience, creative and commercial objective. Manage the selection through product groups, feed labels, product types and custom labels.
A business decision
There is no universal investment level. Demand Gen can support valuable future sales, but may need more patience than campaigns aimed at shoppers already searching.
Keep product data and creative aligned
Demand Gen relies on imagery, titles, prices, sale prices and landing-page information. Incomplete data or unclear creative limits what the campaign can do.
Your action plan
Do not treat every recommendation as equally urgent. Separate immediate operational problems from commercial opportunities and low-value distractions.
Frequently asked questions
The short answers to the questions retailers most often ask when deciding what to do with the report.
The report summarises opportunities across product eligibility, approvals, targeting, impressions, clicks and feed-based campaign activity. Treat it as a diagnostic starting point—not an official Google Ads performance score.
No. A higher score is only useful when the improvements involve commercially important products and contribute to relevant visibility, profitable traffic, conversion or customer acquisition.
Prioritise problems affecting products with strong demand, healthy margins, reliable stock, active campaigns or strategic importance. High-value disapprovals, price and availability mismatches and missing inventory data should generally come before low-impact catalogue cleanup.
No. Accurate eligible products can remain available in Merchant Center for free and organic discovery while campaigns, product groups and custom labels control which products receive paid media investment.
Use Demand Gen selectively for products that match the audience, creative and commercial objective, such as new products, seasonal ranges, high-margin products or visually strong products that need more consideration before purchase.
An offer is an individual product listing that Google can review, match and potentially show to shoppers across eligible paid, free and local shopping surfaces.
Approval confirms that a product can participate, but visibility also depends on targeting, availability, relevance, competition, campaign coverage and the quality and completeness of the product data. Use the Google Shopping ads troubleshooting guide to work through those causes.
Relevant titles, descriptions, product types, imagery and category-specific attributes can help Google understand the product and match it to more suitable searches. Approval, availability and campaign coverage must also be considered.
Prioritise attributes that influence search and comparison in the product category. Apparel may need size, colour and material, while electronics may depend more on brand, model, compatibility and technical specifications.
Review it regularly and after significant catalogue, website, inventory or campaign changes. Allow enough time for feed updates and Google processing before judging the effect of completed fixes.
Clear, accurate and structured product data helps AI-led systems understand what a product is, who it suits, its compatibility, specifications, price, availability and delivery options. It supports product understanding but does not guarantee recommendation or visibility.
FeedOps can audit the catalogue at product and category level, identify the issues limiting eligibility and visibility, improve relevant product data, create dynamic product segments and manage ongoing feed quality.
