You’ve seen them — those little gold stars sitting under some Google ads, right below the web address. “4.6 ★ (1,243 reviews).” They make you trust that business a bit more before you’ve even clicked, don’t they? That’s exactly the point. And this month Google started testing a more prominent version of those stars in Search ads, which is a good reason to finally understand how they work — because a lot of small businesses are leaving them on the table without realizing it.
What those stars actually are
The stars under a Google ad are called Google Seller Ratings (Google officially renamed them “Store Ratings” a while back, but almost everyone still says Seller Ratings). They show your business’s average rating and total review count right in your ad, and they show up automatically once you qualify — you don’t build them or turn them on in Google Ads. Google just starts showing them when you meet the bar.
Why care? Because they’re one of the cheapest performance boosts in all of Google Ads. Google’s own data says ads with seller ratings can get up to 10% higher click-through rates. And here’s the part that really matters: a higher click-through rate improves your Quality Score, and a better Quality Score means you pay less per click. So the stars don’t just get you more clicks — they can quietly lower your cost per click at the same time. More trust, more clicks, lower costs. That’s a rare trifecta.
The confusion that trips up almost everyone
This is the single most important thing in this post, so read it twice. Your Google Business Profile reviews do not count toward these ad stars.
I can’t tell you how many business owners have said to me, “But I’ve got 200 five-star Google reviews — why don’t my ads have stars?” It feels like it should just work. It doesn’t, and here’s why: Google runs several separate review systems that people constantly mix up.
Google Business Profile reviews — the ones on your Maps listing. These power the stars you see in the local map pack and on Maps. They’re huge for local businesses, but they do not feed your Search ad seller ratings.
Google Seller Ratings — the ad stars we’re talking about. These come from a completely different, approved set of sources (more on that below).
Product ratings — stars on individual products in Shopping ads, based on reviews of that specific product.
Three different systems, three different jobs. The reviews that make your Maps listing shine are not the reviews that put stars on your search ads. Once you understand that, everything else makes sense.
What it takes to earn the stars on your ads
For stars to appear on your text Search ads, Google generally wants to see:
At least 100 verified reviews from your country in the past year.
An average rating of 3.5 stars or higher.
Reviews from a Google-approved source — either Google’s own free Google Customer Reviews program, or one of roughly 30 approved review partners (Trustpilot, Feefo, Reviews.io and the like). Reviews from Google Business Profile, Yelp, or Facebook don’t qualify.
A matching domain — the reviews have to be tied to the same website your ad points to.
Hit those, and the stars usually start showing up within two to four weeks — automatically, no setup inside your account required. Quick tip while you wait: don’t sit there searching your own ads over and over to check. Google notices that and will actually stop showing your extensions to you. Ask a friend on a different connection, or just be patient.
The honest part: this is easier for some businesses than others
I’m not going to pretend the 100-review-from-an-approved-source bar is trivial. For an established e-commerce store, it’s very doable — you’re already emailing customers after purchase, so wiring up Google Customer Reviews to collect ratings automatically is mostly a setup job.
For a smaller local service business, it takes more intention. You may have tons of Google Maps reviews and still need to build up reviews through an approved channel to get the ad stars. That’s not a reason to skip it — it’s a reason to start collecting the right way now, especially with Google making these stars more prominent. The businesses that set this up will increasingly stand out against the ones that didn’t.
The bigger picture: reviews are becoming everything
Step back and look at where all of this is heading. Reviews now decide whether your Local Services Ads rank at the top. They heavily influence whether AI search recommends you or a competitor. And now they’re getting more visual real estate on your regular Search ads too. Everywhere you look in Google, the same signal keeps getting more powerful: what other people say about you matters more than what you say about yourself.
Which means a steady, boring, consistent habit of asking happy customers for reviews — through the right channels — might be the highest-return marketing activity a small business can do in 2026. It’s not flashy. It just works, across everything.
Frequently asked questions
Why don’t my Google reviews show on my ads?
Because Google Business Profile reviews don’t count toward ad stars. Seller Ratings on Search ads come from Google Customer Reviews or an approved third-party partner, and you need at least 100 of them from the past year with a 3.5+ average. Your Maps reviews power your local listing stars, which is a separate system.
Do seller ratings cost anything?
The Google Customer Reviews program is free. Third-party review partners charge, but many small businesses can qualify through the free route. Either way, the stars themselves cost nothing to display and can actually lower your cost per click by improving your Quality Score.
How long until the stars appear?
Usually two to four weeks after you meet the requirements. They appear automatically — there’s nothing to switch on inside Google Ads. If they drop off later, it usually means your review volume or average rating fell below the threshold.
I’m a local service business. Is this worth it for me?
It can be, though it takes more effort than for e-commerce since you’ll need reviews through an approved source rather than just your Google Business Profile. Given reviews also drive your Local Services Ads ranking and your visibility in AI search, building a proper review-collection habit pays off in several places at once.
