Show a product's rating once it can withstand a bad review, not before
You'll know which reviews can earn stars next to your link, the ones about a product you sell, not the ones about your own business, how many you should have written on your page before showing the rating, and the test for knowing if it can already withstand a bad one.

The stars next to your link require different proof than the price does before you can show them. Your Google listing has 4.8 stars and 40 reviews. Your page, the one you control, doesn't have a single published review yet. And still you're wondering if you can already show the rating next to your link, the stars that show up before anyone even clicks through to your site.
You can't just copy the number from your Google Business Profile: the star card is built from what's written on your own page, not from what Google has gathered about you somewhere else. And it has to be the rating for a specific product you sell on that page. Google doesn't show reviews about your business overall next to your link when you post them on your own site, whether they're written into the code or added with a widget, even your profile's review widget. And reviews for a service you provide, like a haircut or a consultation, don't count either. If you run a service business, your Google stars are the ones on your profile, and everything below applies to reviews you show inside your own page. If you sell products, the question left is more specific, and it's the one you decide today: how many real reviews do you need posted on your page before you show them?
What needs to be written, not just told
For Google to show stars next to a product link, the reviews that count have to be visible on the page, with who wrote them and what rating they gave, and the page has to make clear where they came from or how to leave a new one; the date and the text are what make them credible. A standalone number like "rated 4.8 out of 5" doesn't count if there aren't real reviews underneath backing it up. A real review on your page looks like this: Maria G., March 14, five stars: "This hair mask lasted me three months and my hair feels noticeably less dry."
A name, a date, a rating, and the reviewer's own words: that's what makes a review the markup can describe truthfully. That shifts the question from "how many reviews do I have" to "how many reviews do I have written, with a name and a date, on the page I want showing up on Google." The ones on your Google listing, the ones in a group chat, or the ones people told you in person don't count here: if they're not written on your page, they don't exist for the markup.
The number that actually matters: how much the average can take
- One weak review swings the whole rating in one shot
- It tempts you to only ask happy customers, or to dress it up
- The page looks brand new even if the business isn't
- One bad review costs a few tenths of a point, not a whole point
- There's enough variety for the markup to have real content to describe
- You can ask for reviews at the business's normal pace, with no rush to fill up the page
Which one do I pick: These numbers are just a guide: Google doesn't require a minimum. Wait for eight to ten if it's a product you sell often; if it's one with few sales, five reviews of that product are already enough. The test that works for any case: mentally remove the best and worst review and recalculate the average. If it barely moves, it's ready to show.
If your competitor already shows it with fewer reviews than you
You'll find stores selling the same thing you do with a rating next to their link and only three or four reviews on the page. That's not a sign that three is enough: it's a risk they're already taking. One bad review is all it takes for their rating to drop suddenly for everyone to see, and if the rating doesn't match what's published, they risk having Google pull it.
Copying their rush doesn't get you anywhere, it just puts you at the same risk. What actually gets you ahead is having your page ready with enough reviews to withstand a bad day, so you can put it up once and never have to take it down.
With that math clear, today's decision isn't "how many stars do I want to show" but "how many real reviews do I already have written on my page, and can the rating hold up with them." If the answer is yes, post it, and let Google decide whether to show it next to your link. If not, keep asking for reviews at your normal business pace until it can.
And once it's up, the rating doesn't stay still: every new review you publish on the page changes the average, and the number Google reads has to change along with it.
With the price and the rating settled, there's still the piece of data that expires on its own even if you never touch it: availability.
- You know the stars next to your link come from product reviews written on your own page, not from your Google Business Profile, and that Google doesn't show reviews about your business overall there
- You have the test to decide when to show it: if you drop the best and worst review and the rating barely moves, it's ready
- You know what has to show in every review: who wrote it and what rating they gave, plus the date and text that make it credible
- You know what it could cost you to fake it: losing the rich result, and not always just on that page
