When a diner searches for your restaurant on Google, they don’t just see your overall star rating. Beneath that headline number, Google displays a second layer of granular feedback: subratings for Food, Service, Atmosphere, and sometimes Value. For dental practices, the categories shift to focus on clinical quality, staff, cleanliness, and wait times. Understanding how Google subratings work—and what they reveal—can help you diagnose exactly where your reputation needs attention.
Most owner-operators glance at their overall Google rating and call it a day. But the subratings tell a much sharper story. A 4.2-star restaurant might excel at food (4.7) while struggling with service (3.6). A dental practice with a solid 4.5 overall might be bleeding stars on wait time (3.9) even though clinical care scores high. These breakdowns surface patterns that a single average obscures, and customers notice them.
What Are Google Subratings?
Google subratings are category-specific scores derived from customer reviews. When someone leaves a Google review, they can assign individual ratings—one to five stars—for specific aspects of their experience. Google aggregates these individual category ratings and displays them publicly on your Business Profile.
For restaurants, the most common subratings are:
- Food – quality, taste, presentation
- Service – speed, attentiveness, professionalism
- Atmosphere – ambiance, noise level, decor
- Value – price relative to portion and quality (less commonly displayed)
For dental and medical practices, Google surfaces different subratings:
- Quality of care – clinical skill, treatment outcomes
- Staff friendliness – front desk, hygienists, assistants
- Cleanliness – office environment, sterilization perception
- Wait time – punctuality, time to appointment
Not every business profile displays all subratings. Google requires a minimum threshold of category-specific ratings before it will publish a subrating publicly. The exact number isn’t disclosed, but in practice you need at least a dozen ratings in a given category before it appears reliably.
How Google Collects Subrating Data
When a reviewer writes a Google review on mobile or desktop, Google prompts them to rate individual categories after they select their overall star rating. The prompts are tailored to your business type—restaurants see Food and Service; dentists see Quality of Care and Wait Time.
Critically, not every reviewer fills out the subratings. Many customers skip the extra questions and submit only an overall star rating and written comment. That means your subrating sample size is always smaller than your total review count. A restaurant with 300 reviews might have only 180 Food ratings and 150 Service ratings.
Google does not allow business owners to choose which subratings to display or to opt out. The categories are determined by your Google Business Category (e.g., “Restaurant,” “Dentist,” “Italian Restaurant”). If you operate in multiple categories, Google may blend the prompts, though the primary category usually dictates which subratings appear.
Why Subratings Matter More Than You Think
Subratings serve two purposes: they help potential customers make faster decisions, and they give you a diagnostic tool to pinpoint operational weak spots.
Customer Decision-Making
When someone is comparing three restaurants at 4.3, 4.4, and 4.2 stars, the overall ratings look nearly identical. Subratings break the tie. A diner prioritizing ambiance will choose the 4.2 restaurant if its Atmosphere score is 4.8. A budget-conscious family will pick the place with the highest Value rating, even if Food is half a star lower.
In our experience working with restaurant and dental clients, subratings influence the type of customer you attract. High Service and Atmosphere scores draw date-night diners willing to pay more. High Value scores bring families and repeat locals. For dental practices, a stellar Wait Time score can be the deciding factor for busy professionals, while Quality of Care reassures patients shopping for complex procedures.
Operational Diagnosis
Subratings reveal which part of your operation is costing you stars. If your overall rating is stagnant at 4.1 and you can’t figure out why, check the subratings. Commonly, we see one category dragging down the average:
- A restaurant with 4.6 Food but 3.7 Service has a front-of-house training problem, not a kitchen problem.
- A dental office with 4.8 Quality of Care but 3.9 Wait Time needs to rethink scheduling, not clinical protocols.
- A bistro with 4.5 Food and Service but 3.8 Atmosphere might need better lighting, music, or a refresh of worn furniture.
This level of specificity is hard to extract from written reviews alone. The monthly Get Kandid Report surfaces these patterns automatically, tagging mentions of “slow service,” “long wait,” or “loud” and correlating them with subrating trends. You get a clear picture of where to invest time and money.
How to Improve Each Subrating
Once you know which subrating is underperforming, the fix is usually tactical.
Food (Restaurants)
Low Food scores point to inconsistency, underseasoning, portion size complaints, or a mismatch between menu description and what arrives. Read the text of reviews that mention specific dishes—often a single menu item drags down the whole category. Pull that dish, retrain on it, or adjust the description to set accurate expectations. For more on how dish-level feedback drives profit, see our guide on menu engineering reviews.
Service (Restaurants and Dental)
Service subratings drop when staff are inattentive, slow, or rude. Check your staffing levels during peak hours—understaffing is the most common culprit. Our data on peak hour complaints and staffing shows a clear correlation between thin coverage and service mentions in negative reviews. Cross-train front-of-house staff so no single person becomes a bottleneck. For dental practices, front desk tone and efficiency dominate this score.
Atmosphere (Restaurants)
Atmosphere encompasses noise, lighting, cleanliness, and overall vibe. If your Atmosphere score lags, read reviews for words like “loud,” “cramped,” “dirty,” or “uncomfortable.” Small fixes—better table spacing, acoustic panels, consistent cleaning schedules—can move the needle quickly. This is rarely about a full remodel; it’s about consistency and attention to detail.
Wait Time (Dental)
Wait Time is the Achilles’ heel for many dental practices. Patients tolerate clinical delays less than they tolerate restaurant waits. Block scheduling more conservatively, build in buffer time for complex cases, and communicate proactively when the doctor is running behind. Even a five-minute heads-up from the front desk can prevent a one-star review.
Value (Restaurants)
Value is the ratio of price to quality and portion size. If your Value score is low but Food and Service are high, you may be charging premium prices without communicating why. Highlight sourcing, scratch cooking, or unique ingredients on the menu and in review responses. Alternatively, consider portion sizes—Value complaints often mention “small plates” or “overpriced.” For deeper patterns on pricing and reviews, see our analysis of restaurant pricing complaints.
How Subratings Affect Your Overall Google Rating
Google’s overall star rating is not a simple average of your subratings. It’s the mean of all individual overall ratings that reviewers assign. The subratings are displayed separately and do not mathematically roll up into the headline number.
That said, there’s a strong correlation. Reviewers who give low marks in one subrating category often give a low overall rating too. If someone rates your Service at two stars, they’re unlikely to award you five stars overall—even if your Food was excellent.
This means improving a lagging subrating will, over time, lift your overall score. Fix your Wait Time problem, and future reviews will likely come in higher across the board. The inverse is also true: ignore a weak subrating, and it will continue to anchor your overall rating below where it could be.
Subratings and Review Response Strategy
When you respond to a review that mentions a specific category—”food was great but service was slow”—acknowledge both the praise and the gap. This signals to future readers that you monitor feedback at a granular level and that you’re working on the issue.
Example: “Thank you for the kind words about the food. We’re sorry our service didn’t match that standard during your visit. We’ve added staff for Friday evenings and are retraining on timing. We’d love to earn back your confidence.”
This kind of specificity reassures prospective customers that the problem is being addressed. It also trains your team to think in categories—Food, Service, Atmosphere—rather than treating every complaint as a vague “bad experience.” For benchmarks on how quickly top-rated businesses respond, see our data on review response time.
Common Subrating Mistakes
We see a few recurring errors when businesses try to interpret or improve their subratings:
- Ignoring small sample sizes. If you have only eight Service ratings, one angry review can tank that score by half a star. Don’t overreact to subratings until you have at least 20–30 data points in that category.
- Conflating subrating with written feedback. A customer might rate Service at three stars but write only about Food. The text and the category rating don’t always align. Look at both.
- Assuming subratings are static. They update in real time as new reviews come in. A single stellar month can shift a subrating noticeably if your total volume is modest.
- Neglecting categories that don’t display. Just because Value or Cleanliness isn’t visible on your profile doesn’t mean Google isn’t collecting that data. It may surface later as your review count grows.
Tracking Subratings Over Time
Google does not provide a historical view of subratings in the Business Profile dashboard. You see only the current aggregate. To track trends, you need to log subratings manually each month or use a tool that monitors them automatically.
The monthly Get Kandid Report includes subrating tracking as part of the standard deliverable. Each month you get a snapshot of how Food, Service, Atmosphere, and other categories have moved, along with a breakdown of which new reviews mentioned those themes in their text. This makes it easy to correlate a training initiative or menu change with a measurable shift in a specific subrating.
FAQ
Can I choose which subratings appear on my Google Business Profile?
No. Google automatically selects subrating categories based on your primary business category. You cannot add, remove, or customize them. If a subrating doesn’t appear, it’s because you haven’t yet received enough category-specific ratings from reviewers for Google to display it publicly.
Do subratings affect local SEO ranking?
Google has not confirmed that subratings directly influence local search ranking. However, higher subratings often correlate with more positive reviews, higher overall ratings, and better engagement—all of which do affect ranking. Improving subratings indirectly supports your visibility in local search by lifting overall review quality and volume.
What if my subratings are higher than my overall rating?
This happens when some reviewers leave a low overall rating without filling out subratings, or when early reviews (before subratings were introduced) dragged down your average. It’s not uncommon. Focus on generating new reviews that capture both overall and category-specific feedback. Over time, the gap will narrow as older reviews age out of the visible set.
How many reviews do I need before subratings appear?
Google doesn’t publish an exact threshold, but in practice, expect to need at least 10–15 category-specific ratings before a subrating displays publicly. For some categories like Value, the bar may be higher. Keep encouraging detailed reviews, and the subratings will surface as your volume grows.
Putting Subratings to Work
Google subratings are one of the most underused diagnostic tools available to restaurant and dental practice owners. They cost nothing, update in real time, and tell you exactly where your customer experience is breaking down. Instead of guessing why your rating isn’t climbing, you can see whether the problem is Food, Service, Wait Time, or Atmosphere—and fix it.
The challenge is that most owners don’t have time to monitor subratings manually, cross-reference them with written feedback, and track changes month over month. That’s where a structured review process helps. If you want to see how your subratings compare to your competitors and which themes are driving them up or down, you can start by getting the free sample report—no card required, no sales call. You’ll get a clear breakdown of your current subratings, the review patterns behind them, and a roadmap for where to focus next.
