The short answer
Install a supported embed in the theme and verify it does not affect checkout or mobile performance.
- Add the widget through a Custom Liquid or HTML section in your theme.
- Store reviews are different from Google reviews about your business.
- Check speed and mobile layout after adding it.
01Google business reviews versus product reviews
Google Business Profile reviews typically describe the business or customer experience. Shopify product reviews relate to specific products. Do not treat the two as interchangeable or imply a store-level Google rating applies to every product.

Business-level Google reviews are most useful on the homepage, About page or a trust section. On a product page, use product-specific feedback if available, with accurate attribution. Avoid putting a large Google carousel above product information.
03Add a supported embed
If your theme or provider offers a compatible app block, use that. Otherwise, where your theme and permissions allow, add a custom Liquid or HTML section containing the public embed snippet. Work on a duplicate theme first and test before publishing. Never paste private Google OAuth tokens into theme files.
04Theme editor and code limitations
Some Shopify editors sanitise code or restrict where scripts run. A third-party widget may require a theme app extension or a supported iframe. Confirm the actual integration method rather than assuming every theme accepts arbitrary JavaScript.
05Performance and mobile
Check storefront performance and layout on mobile, particularly around sticky add-to-cart controls. Load the widget asynchronously and avoid placing several carousels on the same page. Test review links, touch gestures and keyboard focus.
06Compliance and consumer trust
Show the genuine review source and required reviewer attribution. Do not combine Google Business Profile review counts with product review counts or calculate a misleading blended star score.
07What to do if you have no Google Business Profile
You can still build trust using verified product reviews or appropriately sourced customer testimonials. Do not fabricate a Google badge or claim a rating your business does not have.
08Where reviews earn their place on a Shopify store
Business reviews and product reviews answer different questions. A product review tells a shopper whether a candle smells as described. A Google review tells them whether the shop behind it delivers on time, packs carefully and sorts out problems. Both matter, but they belong in different places.
| Page | What the shopper is wondering | What to show |
|---|---|---|
| Home page | Is this a real, trustworthy shop? | Google rating badge or short carousel below the hero |
| Product page | Is this product any good? | Product reviews; a small Google badge near delivery info |
| Cart | Will my order actually arrive? | One or two reviews mentioning delivery or service |
| About page | Who runs this? | A wall or grid of Google reviews beside your story |
| Contact / FAQ | What happens if something goes wrong? | Reviews that mention returns or customer service |
Keep the checkout clean
Shopify's checkout is deliberately locked down. Put reassurance on the cart page instead, where you can still add a theme section or app block.
09A worked example: a Galway gift shop
Imagine a gift shop in Galway with a physical store and a Shopify site. Its Google profile has 140 reviews from in-store customers, while its newer product reviews app has only a handful. The owner's plan, purely illustrative, might look like this:
- 1
Home page carousel
A carousel of recent Google reviews sits under the hero, so first-time visitors see that real people shop there.
- 2
Delivery reassurance
On product pages, a compact badge with the overall Google rating sits beside the delivery and returns note rather than competing with the product photos.
- 3
About page grid
The full grid lives on the About page alongside a photo of the shop front, connecting the online store to the physical one.
- 4
Ask after delivery, not after payment
Review requests are sent a few days after the parcel arrives, when the customer has actually experienced the service.
10Asking online customers for a Google review
If you have a Google Business Profile, online customers can review it too. Time the request for after delivery, keep it short and make it clear any honest feedback is welcome.
Hi Aoife, your order from Harbour Gifts should have arrived by now. If you have a minute, we'd really value your honest feedback on Google — it helps other people find us: [review link]. If anything wasn't right, just reply to this email and we'll sort it. Thanks, Niamh
No discount codes for reviews
Offering a discount in exchange for a review breaks Google's policies and consumer protection rules in Ireland and the UK. A thank-you for the order is fine; a reward for the review is not.
11Pre-launch checklist for Shopify themes
- Preview the widget in the theme editor on both desktop and mobile views.
- Check it on the live store in a private window, not only in the editor.
- Make sure it doesn't push the add-to-cart button below the fold on mobile.
- Confirm each review links back to Google or clearly shows its Google source.
- Test page speed before and after adding the widget.
- If you change theme, re-add the embed — custom sections don't always carry over.

Frequently asked questions
Can I add Google reviews without coding?+
Usually yes. Many website builders provide a custom HTML or embed element, although permissions and script restrictions vary by plan.
Will a Google Reviews Widget improve my SEO?+
Not automatically. It can support user trust and useful content, but rankings depend on many factors and Google restricts self-serving review snippets.
Can I display only five-star reviews?+
Some products allow selection, but displaying only positive feedback can mislead visitors. Keep any overall rating truthful and clearly distinguish curated highlights from the full review set.
Is a Google Reviews Widget free?+
Some providers offer free plans. Check the limits, branding, data source and whether it is a permanent free tier.
Do I need access to my Google Business Profile?+
It depends on the provider and its permitted data source. Some approaches require an authorised Google connection; others use limited public listing data.
Can I show Google reviews on Shopify product pages?+
Yes, but think about relevance. Google reviews describe your business, not a specific product, so a small rating badge near delivery or returns information usually works better on product pages than a large carousel. Keep detailed product feedback for a product reviews app and use Google reviews for overall trust.
Will a Google reviews widget slow down my Shopify store?+
A well-built widget loads after the main page content and should have little effect. Test with PageSpeed Insights before and after installing it, place it below the main content where possible, and avoid stacking several review apps on the same page, which is the more common cause of slow stores.
Do I need a Shopify app to show Google reviews?+
Not necessarily. Many themes let you add a Custom Liquid or custom HTML section where you can paste an embed code. An app can be easier if your theme doesn't support custom code, but check what it requests access to and whether it shows genuine, attributed Google reviews.
Can online-only shops collect Google reviews?+
Google Business Profiles are designed for businesses that serve customers in person, at their location or in a service area. Some online-only shops won't qualify. If you can't have a profile, focus on product reviews and an independent review platform instead of trying to create a listing that breaks Google's guidelines.
