You installed a recommendations app. Maybe you even paid for one. The widgets are live, products are showing up, and technically everything is "working."
But your click-through rate is sitting under 2%. Revenue attributed to recommendations is a rounding error. And you're starting to wonder if product recommendations are one of those ecommerce tactics that sounds good in blog posts but doesn't actually move the needle.
They do. Recommendation engines drive 10-30% of revenue for stores that implement them correctly. The gap between that and what you're seeing isn't a concept problem. It's an execution problem.
Here are the six most common reasons Shopify product recommendations underperform, and what to do about each one.
1. Your recommendations are buried below the fold
This is the most common and most fixable mistake. Merchants install recommendation widgets on the product page, scroll down to confirm they're showing up, and move on. The problem: those widgets are sitting below three paragraphs of product description, a size chart, a shipping FAQ accordion, and two sections of customer reviews.
Most visitors never scroll that far. They look at the product, decide yes or no, and either add to cart or bounce. If your "You may also like" section requires 4-5 scrolls to reach, it's invisible to 70-80% of your visitors.
Where recommendations should live instead:
Place them directly below the product image and add-to-cart button, before the extended description and review sections. On mobile especially, that first screenful is where buying decisions happen, and most recommendation widgets get pushed to the bottom of a very long page.
The homepage is another missed spot. Your homepage gets more traffic than any other page, but most stores use it as a static billboard. A "Trending now" or "Picked for you" section above the fold on your homepage creates immediate engagement and gives visitors a reason to click deeper into your catalog.
Test this for yourself: open your store on your phone. Count how many thumb-scrolls it takes to see your first recommendation widget. If it's more than two, you have a placement problem.
2. You're showing "popular products" instead of personalized ones
The default recommendation logic for most Shopify apps is some version of "show your bestsellers everywhere." It's the easiest algorithm to build, and it looks reasonable at first glance because the products it surfaces are, by definition, things people buy.
