The Psychology Behind Product Comparisons
Great UX and UI isn’t just about looking good, it’s about aligning with how people actually make decisions. Product comparisons tap into several well-documented psychological principles:
-
Hick’s Law: The more choices you present, the longer it takes to decide. Comparisons reduce “analysis paralysis” by making information clearer.
-
Anchoring Effect: When two similar products are shown side by side, customers tend to anchor on the first and judge the others against it. Smart merchants highlight the mid-tier product as the “best value.”
-
Choice Overload: Too many options without clear differences create confusion. Comparisons clarify distinctions (e.g. size, features, warranty).
-
Loss Aversion: When customers see what they’re missing by not upgrading, they’re more likely to choose the higher-value option. Boosting your average order value.
This is why comparison tables, “best seller” badges, and feature highlights work so well in Shopify stores.
It’s important not to think of comparison UX purely as traditional tables. Even on a collection page, customers are constantly comparing products side by side before deciding which one to click or add to cart.
There are many creative ways to achieve this through bespoke UX design. This is something I help clients explore in the design phase of their Shopify projects. Learn more about my Shopify website design process.
Real-World Shopify Examples
While not every store uses side-by-side tables, many leading Shopify brands use comparison UX patterns:
Even when you don’t see a formal table, the principle remains the same: reduce decision friction, make comparisons easy, and help customers choose faster.
Casper
Their dedicated “Compare Mattresses” section allows users to see key features side by side in a clean, scannable format, a textbook case of comparison UX in action.
Allowing just two products at a time makes this design manageable on mobile.
Stovefitter's Warehouse
Since many shoppers compare stoves across different sites and brands, we wanted them to do this within the Stovefitters Shopify store. I designed a “sticky compare” feature that lets users add products themselves and view them side by side.
Drink Finder
This design allowed users to expand product cards to show more options directly on the collection page. This way, customers could make informed decisions without needing to click through to multiple product pages.
Not Every Store Uses Tables
Many Shopify stores avoid formal side-by-side tables but still use subtle comparison tools like badges, filters, and product highlights. For example, lifestyle brands often use “Best Seller” tags or colour-coded filters to guide customers without overwhelming them.
The Business Case: Why Comparisons Increase Conversions
According to Baymard Institute, comparison features directly improve product page usability and decision confidence. For Shopify stores, the benefits include:
-
Reduced Returns: Customers make more informed choices, so they’re less likely to buy the “wrong” item.
-
Higher Average Order Value: Highlighting upgrades nudges buyers toward premium options.
-
Increased Trust: Transparent comparisons show you’re not hiding information.
-
Faster Purchase Decisions: Less confusion means fewer abandoned carts.

How to Implement Product Comparisons in Shopify
1. Comparison Tables
Ideal for electronics, supplements, software, or any product with features that can be lined up side by side.
-
Apps: Product Compare by Omega or Yotpo.
-
Top tip: Highlight the “recommended” product with a badge or subtle colour shift.
2. Guided Quizzes
For lifestyle brands, quizzes simplify choices while gathering customer data.
-
Example: Which mattress is right for you? or What Coffee would you like?
- App: Recharge.
I have worked on a lot of quizzes which show a curated selection of products at the end. Utilising apps like Recharge can easily badge on subscriptions into this flow, which is great for ongoing sales.

3. Badging & Highlighting
Not every store needs a table. Sometimes a simple “Best Seller” or “Most Popular” badge does the job.
Amazon’s approach is a gold standard, highlighting products with the best value or products with the biggest saving.
4. Filtering & Faceted Navigation
Let customers self-compare by filtering by attributes (size, colour, price, rating).
-
Shopify supports this natively, but UX tweaks can make it far more usable.
My Microinteractions in Shopify Design article is a helpful guide on how you can make filters, badges, and highlights a better user experience.
Design Best Practices for Comparisons
-
Keep it simple: No more than 3–4 products side by side.
-
Use icons: Visuals are processed faster than text.
-
Highlight differences: Don’t just list features — call out what’s unique.
-
Mobile first: Ensure tables stack properly and remain scannable.
-
CTA placement: Always keep “Add to Cart” or “Shop Now” buttons visible.
Step-by-Step: Adding a Comparison Table to Shopify
-
Identify comparable products (don’t compare completely unrelated items).
-
Choose your attributes (size, weight, features, guarantee).
-
Select a format (table, quiz, badge).
-
Test it — check usability on mobile, ensure no performance issues.
-
A/B test with and without comparison to see the uplift in conversions.
These are not cookie-cutter approaches, each of these would need to be bespoke to your store and more importantly your users needs. For example a user looking for a new Coffee to try is a completely different user case to someone looking to purchase a new Sofa. All of their needs are different, and they would have different questions that need answering.
