Google Reviews – Bigger Stars, Better Results?
Customer reviews have long played an important role in eCommerce, helping shoppers assess products and businesses before committing to a purchase. Now, Google is testing a new mobile Search ad layout that gives product review stars significantly more prominence within sponsored results, highlighting just how valuable trust signals can be when businesses compete for attention.
Search Engine Roundtable reported in August 2026 that Google was testing a new layout for review stars within mobile sponsored results. The experiment gives the review star considerably more visual space, making the rating much more noticeable within the advertisement.
It appears to be a test rather than a confirmed permanent change, and no specific location was confirmed for this test — some Australian mobile users may have seen it, but it wasn’t a dedicated Australia-only rollout as Google typically rolls out small-scale UI experiments like this to a tiny percentage of global traffic or specific test groups.
While the design itself may or may not roll out more broadly, the experiment points to search results are becoming increasingly visual and information-rich, and Google continues to surface signals that can help consumers evaluate businesses before clicking through to a website.
Reviews are particularly valuable because they reduce uncertainty – when customers cannot physically inspect a product, speak with staff or experience a business before purchasing online. Instead, they rely on information such as ratings, reviews, pricing, delivery expectations and returns policies to determine if a retailer can be trusted.
Google already uses store ratings across several shopping experiences. According to Google Ads Help, store ratings can appear in text ads, unpaid rich results and free product listings. They can include a rating out of five stars, the number of ratings received, information about aspects of the shopping experience and a link to recent reviews.
Google also reports that store ratings on text ads drive an average 2% improvement in click-through rate on the search network. While results will vary between businesses and campaigns, this demonstrates the potential commercial value of making customer trust visible before someone reaches a retailer’s website.
Eligibility is important. Google states that store ratings for text ads generally require a composite rating of at least 3.5 stars. Google also needs enough eligible reviews to confidently calculate a store rating, with most merchants able to receive one after collecting 100 or more eligible reviews within a country over the previous 24 months. Ratings can come from Google Customer Reviews, supported third-party review partners and Google’s own evaluations.
For retailers, this makes review generation more than a reputation management exercise. Reviews can become part of the acquisition journey itself. A strong rating appearing beside an advertisement can provide immediate reassurance and help a retailer differentiate itself before a prospective customer has even clicked.
The prominence of reviews can be particularly significant in competitive search environments. A visible rating introduces another decision-making signal, allowing shoppers to quickly assess the perceived credibility and customer experience of each business.
The strongest review strategy therefore starts with delivering an experience customers genuinely want to recommend – Google’s systems draw on customer feedback relating to the overall shopping experience, making fulfilment, delivery, service and post-purchase support important parts of the equation.
This also reinforces the importance of the post-purchase customer journey. Automated review requests, clear communications and simple feedback processes can help businesses generate a consistent stream of authentic customer reviews. At the same time, monitoring feedback can reveal recurring problems that need to be addressed across fulfilment, customer service or the website experience.
