How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

A practical guide for merchants sitting one band below the Top Quality Store badge. Written for the marketing, content and development teams who have to do the work – with the sequencing that gets there fastest.

1. What Happened? How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

You open the Store Quality page in Merchant Center and see a green dot next to Great — Well above average. One band to the right sits Exceptional, and next to it the Top Quality Store badge you do not have.

This is the most frustrating position in the whole programme. You are demonstrably doing well. Nothing is broken. There is no error to fix, no disapproval to appeal, and no obvious next action — because Google’s summary tends to offer a couple of generic suggestions and leave you to work out the rest.

Here is what is actually happening underneath. Your overall quality score is an impression-weighted average of individual metric scores, grouped into categories, and benchmarked against other merchants in your vertical and your country — health and beauty shops in the United Kingdom, for instance, rather than all retailers everywhere. Each metric is rated Low, Fair, Good, Great or Exceptional. Those roll up into your overall score. Reach Exceptional overall and the badge is awarded automatically.

Two facts change how you should approach this, and most merchants know neither:

• You do not need Exceptional in every category.

Google states this explicitly. You need enough weight in the right places to pull the overall average across the line. That means the game is not “improve everything” – it is “identify the cheapest metrics to push to Exceptional and do those.”

• Missing data is worse than mediocre data.

If you have not supplied return cost, or you are providing offer-level shipping without both cost and transit time, that metric does not get scored – and an unscored metric is dead weight against your overall average. There is no penalty for scoring badly, but there is a real cost to not being scored at all.

Put those together and the fastest route from Great to Exceptional usually starts with a form, not a photoshoot.

2. Why Does It Matter? How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

• The badge is a ranking and trust signal you cannot buy.

Unlike third-party trust seals, this one is algorithmic and earned, which is precisely why shoppers respond to it. It appears alongside your Shopping listings and free product listings, and Google positions badged stores more prominently in Shopping surfaces and the Stores filter. In a category where five merchants show the same product at the same price with the same manufacturer image, a badge is the only visible differentiator.

• It is a rewards programme, not a penalty regime.

You lose nothing by scoring Fair. But you also gain nothing, and your competitors who have done the work are collecting the difference. In crowded verticals — health and beauty being a good example — the badge is increasingly table stakes rather than a bonus.

• The work is genuinely cheap relative to the return.

Widening a return window is a policy decision that takes an afternoon to implement. Supplying return cost data is a form. Re-exporting product images at a higher resolution is a batch job. Compare that to the cost of moving one position in organic rankings.

• Thresholds move, so this is maintenance, not a project.

Google is explicit that standards and criteria are updated regularly, and that stores can gain or lose the badge independent of any change in their own signals. Whatever you build needs an owner and a monitoring cadence, or you will earn the badge and quietly lose it.

• Everything is impression-weighted.

This is the single most useful mechanic in the programme, and it is what makes the work tractable for a small team. Your highest-impression products carry the most weight. You do not need to fix a 5,000-SKU catalogue. You need to fix the few hundred products that generate most of your Shopping impressions.

3. Who Is Affected? How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

• Merchants already sitting at Great.

This guide is written for you. You are close enough that a focused four-to-six week programme is realistic.

Merchants at Good or below will find the same sequence applies, but should expect a longer run and should prioritise the missing-data audit even more aggressively, since blanks are usually the reason for a middling score.

Health, beauty and supplement retailers face a specific problem: your peer benchmark is unusually strong. In UK health and beauty, seller ratings cluster at 4.9 and above, which means a 4.8 — objectively excellent — scores only as market average. Know your benchmark before you set expectations with a client or a board.

Merchants relying on manufacturer imagery — common in health, electronics and homeware — will find the browsing experience metrics are their weakest area, because supplier assets are typically one image at whatever resolution the supplier felt like providing.

By team:

• Operations and finance own the return window and return cost decisions. These are commercial policy calls, not marketing ones, and they are usually the fastest wins.
• Development and feed management own the data completeness, the image pipeline and the feed attributes.
• Content and creative own image production for the priority SKUs.
• Customer service owns the review volume that moves the seller rating.

4. What Should Businesses Do? How to Move Your Google Merchant Center Quality Score From “Great” to “Exceptional”

Work in this order. It is sequenced by cost-to-impact ratio, not by category.

Step 1 — Audit for missing data (half a day)

Before improving anything, find what is not being scored. In Store Quality, any metric showing no rating is either missing data or has insufficient impressions in the lookback period. Check specifically:

• Return cost — the most commonly missing field, and the one Google flags most often.
• Return window — often set once at launch and never revisited.
• Shipping cost and transit time — and critically, if you supply these at offer level, you must supply both for each offer. Supplying one without the other leaves the offer unscored.
• Business information and returns policy on the website — Google validates against your published policy pages. If your Merchant Center settings say 30 days and your website says 14, expect problems.

This step costs nothing and frequently produces the largest single movement.

Step 2 — Make the policy decisions (one week, mostly waiting for sign-off)

• Return window.

Google’s guidance to merchants sitting below Good is typically to widen to at least 7 days. Treat that as the floor, not the target — 30 days is common among Exceptional merchants and is the standard UK shoppers expect. This is a commercial conversation about return rates versus visibility, and it deserves a real answer rather than a default.

• Return cost.

Free returns score best. If free returns are not viable, supplying an accurate cost still beats supplying nothing.

• Delivery time.

This is measured on handling plus transit. If you are at five days, the levers are handling time (usually the compressible part), carrier service level, and whether you are using carrier-calculated rates with an accurate shipping origin — which lets Google show faster times to nearby customers rather than a flat worst-case estimate.

• Delivery cost.

Benchmarked against your vertical rather than scored absolutely, so a free-shipping threshold that undercuts your category norm is what moves this.

Step 3 — Fix image resolution (one to two weeks, mostly automated)

This is the underrated one. Google’s high-resolution threshold is greater than 1048 pixels. Many merchants sit in single-digit percentages here — not because the source assets are poor, but because the CMS or CDN is serving downscaled derivatives, or images were exported once at 800px and never revisited.

For the development team:

• Audit the actual pixel dimensions of the image served at image_link for every product. Do not audit the source file — audit what Google receives.
• Check whether your CDN or image proxy is resizing on the fly. This is the most common cause of a low score with good source assets.
• Re-export from source at a minimum of 1200px on the longest edge. Aim for 1600px where source quality allows.
• Confirm no promotional text, watermarks, borders or logos are burned into images. That is a separate policy risk as well as a quality one.

A merchant sitting at 8% high-resolution images can usually reach 80%+ in a single sprint, without commissioning a single new photograph.

Step 4 — Increase images per offer (two to four weeks, impression-weighted)

Now the lever most people reach for first. The metric measures the average number of images per product. Merchants scoring well typically sit at four or more; the top of the range runs to eight.

• Do not do this alphabetically.

Because scoring is impression-weighted, export your Shopping impressions by product, sort descending, and work down. The top 20% of products by impressions will move your score far more than the remaining 80%.

Target four to six images per priority product, following a consistent pattern:

1. Main image — product on plain background, front-facing
2. Packaging or box contents
3. Reverse or ingredients/specification panel
4. Product in use or in context
5. Scale reference
6. Detail or texture shot

• Implement at feed level, not through the UI.

The Merchant Center interface allows adding images product by product, which is fine for a handful of items and unworkable for a catalogue. At scale, use the additional_image_link attribute in your product feed — it supports up to 10 additional images alongside your main image_link. Populate it from your CMS gallery, and if your platform cannot expose that easily, use a supplemental feed keyed on id to add the URLs without touching the primary feed.

For merchants dependent on supplier imagery: request full asset packs from suppliers as a condition of listing, and use lifestyle and packaging photography you shoot yourself to fill the gaps. Product Studio can generate additional angles and backgrounds, which is a reasonable stopgap — but original photography of your actual product will always be the stronger asset.

Step 5 — Move the seller rating (ongoing, slowest lever)

If you are at 4.8 and your benchmark clusters at 4.9, you need volume more than you need perfection. A handful of poor reviews weighs heavily on a small sample; the fix is more reviews, not fewer complaints.

• Enrol in Google Customer Reviews if you have not, so post-purchase surveys fire automatically.
• Trigger the request after delivery is confirmed, not after dispatch. Asking while the customer is still waiting is how you generate the three-star reviews you are trying to dilute.
• Route dissatisfied customers to support before they reach the review form.
• Be patient. This metric moves over months, not weeks, which is exactly why you should not start here.

Step 6 — Purchase experience housekeeping (one day)

Two easily overlooked metrics sit in this category: promotions disapproval rate and eWallet support. Clear any disapproved promotions, and confirm you support the digital wallet options common in your market. Both are quick checks that occasionally account for a surprising amount of drag.

Prioritisation at a glance

Add images to top-impression products	Medium–high	Medium	Content / creative
Reduce handling and delivery time	Medium	Medium	Operations
Improve seller rating	High	Slow	Customer service

What to expect, and when

Scores are calculated on a rolling 30-day window and do not update instantly. Plan for changes to appear over several weeks rather than days, and do not re-plan after a week of no movement. Set a realistic expectation with stakeholders at the outset: a merchant sitting at Great, executing steps 1 to 4 properly, should be assessing progress at six to eight weeks — not at day ten.

Once you reach Exceptional, the badge is awarded automatically with no application. You can then embed the badge widget on your own site, which is worth doing — the trust benefit off-platform is arguably larger than the on-platform one.

5. What We’re Watching Next

• Browsing experience is still in beta, and it will expand.

The two current metrics — resolution and image count — are the most basic measures of page quality imaginable. It would be surprising if this category did not grow to include richer signals: description quality, structured data completeness, page performance, mobile experience. Merchants who build an image and content pipeline now will be positioned for whatever is added; those who batch-fix two metrics will be doing this again.

• Benchmarks ratchet upward.

Every metric here is relative to your vertical in your country. As competitors improve, the bar for Exceptional rises. This is not a score you earn once. It is a position you hold, which makes the monitoring cadence more important than the initial push.

• Product imagery is becoming an AI retrieval asset, not just a merchandising one.

As shopping surfaces become increasingly multimodal, the number and quality of images attached to a product start to matter for how well that product can be understood and surfaced — not only for how well it converts. The work in step 3 and step 4 is likely to pay off twice.

• Badge criteria will keep changing.

Google states plainly that standards are updated regularly and that merchants can gain or lose the badge independent of their own signal quality. Build the review into a monthly operational rhythm rather than treating it as a campaign.

Szymaniak Digital is an enterprise AI SEO consultancy working with e-commerce brands on visibility across classical search, Shopping surfaces and AI-mediated discovery.

Most merchants stuck at Great are not stuck for lack of effort. They are stuck because they started with the most expensive lever – usually photography – instead of the missing form field that was costing them a whole metric. The sequence matters more than the intensity.

If you want an audit that identifies which three metrics will actually move your overall score, and a build plan your development team can execute, that is work we do.
