Adding aggregateRating with Review markup to our Product schema consistently earned star rich results in Google. We implemented JSON-LD Product schema using real, first-party reviews pulled dynamically from the database, making sure the rating value and review count matched what was visible on the page. Reviews were nested directly under the Product entity to stay fully compliant with Google's guidelines. The biggest impact was on CTR, which increased by roughly 20 percent, while impressions stayed mostly flat. The star ratings made the listings stand out in competitive SERPs and drove more qualified clicks without needing ranking gains.
To me, having correct product schema is crucial to improve the Click-through-rate. Rich snippets showing price, offer, delivery time or average rating and number of product reviews are critical to beat your competitors. and should be leveraged, especially if your offer is better or you have great reviews. On top of that, with ChatGPT and Gemini now allowing agentic shopping, having complete product schema will be key to get visibility in LLMs and generate revenue from this stream in the next coming weeks/months.
