The Catalog Trap: Does More Choice Actually Hurt Your Ecommerce Sales?

You added the products because it felt like progress. New lines, more variants, another six colorways, a “shop all” page that finally looks like a real store instead of a starter kit. Traffic held. The catalog doubled. And the conversion rate did nothing — or quietly slid.

So the question every operator eventually asks: does more choice hurt ecommerce sales? The honest answer is the one most CRO advice skips. Sometimes it does. Sometimes it helps. And the difference isn’t luck — it’s diagnosable.

The study everyone quotes — and what it actually found

In a California gourmet market, Sheena Iyengar and Mark Lepper set up a tasting booth. Some hours it displayed 24 jams; other hours, 6. The big display pulled a bigger crowd — 60% of passersby stopped, versus 40% for the small one.

Then the till told a different story. Of the shoppers who stopped at the 6-jam table, about 30% bought a jar. Of the shoppers who stopped at the 24-jam table, only 3% did. Same product, same store, same price. The authors called it choice overload: past a point, more options stop feeling like freedom and start feeling like work, and a shopper who feels the work often just leaves.

The uncomfortable follow-up: choice overload isn’t a law

A decade later, Benjamin Scheibehenne, Rainer Greifeneder, and Peter Todd ran a meta-analysis of roughly 50 experiments on choice overload. Their finding: the average effect of adding options was close to zero. Some replications found the jam effect. Some found the opposite. Many found nothing.

That means “cut your SKUs” is not a fix. It’s a coin flip dressed up as a best practice. The conversion rate is a symptom. Your assortment is a variable, not a verdict.

When more choice hurts — and when it helps

More choice tends to hurt when:

• The options are hard to compare. Complexity, not count, is the load.
• The shopper arrives without a preference. Cold traffic dropped onto a 200-item grid has been handed a decision it isn’t equipped to make.
• There’s no obvious default or “best” pick. When nothing is flagged as the popular or safe choice, every option carries equal weight.
• The decision happens under scarcity of time or attention. Mobile, in a spare two minutes — that’s most of your traffic.

More choice tends to help when the buyer knows what they want, the options are easy to sort and filter, and range is itself the reason to trust you. What decides it isn’t the number of products. It’s the fit between your assortment and your shopper’s readiness to choose.

A five-question audit before you touch a single SKU

1. Where does conversion actually break? If cold traffic tanks on category pages while returning or search-led traffic converts fine, you have a guidance problem, not a catalog problem.
2. Is anything doing the deciding for the shopper? A “most popular,” a bestseller sort, a starter set.
3. Can two similar products be told apart in five seconds? Undifferentiated near-duplicates are pure load.
4. How heavy is the decision on a phone, at a glance? Count the choices visible at 390px wide before the first clear next step.
5. Would narrowing the path work better than narrowing the catalog? Filters, a guided “help me choose,” a curated edit on top of the deep range.

Most stores that “have too many products” don’t. They have too little curation sitting on top of an honest amount of product. The fix is rarely deletion. It’s a default, a sort order, a guided path, and a reason for the unready shopper to trust one choice over the paralysis of all of them.
