A/B test: show stars and review count below the product title
If you show the stars and the number of reviews right below the product name, then you will get more add-to-carts, because shoppers see the social proof without having to dig for it at the bottom of the page.

Why it might work
Many stores have good reviews buried at the end of the product page, after the description, related products and the shipping info. On mobile that is six screens away from the button. Someone who is unsure never gets that far.
"4.7 ★ (128 reviews)" under the title gets read along with the name and the price. And if it links down to the reviews, anyone who wants details is one tap away.
How to set it up
In Bixlow you describe the change to the agent, it builds it on your site and launches it as an A/B test once you approve it.
- Check that your products have enough reviews. "5 ★ (1 review)" convinces nobody.
- In the variant, add the stars, the score and the review count below the title, linking to the reviews section.
- Write the score in text too ("4.7 out of 5"), not only as star icons.
- Run it only on products with a minimum number of reviews, ten for example, and leave the rest as they are.
