How to compare two Shopify stores side by side

A repeatable way to put two stores next to each other — theme, apps, fonts and colours — and turn the differences into decisions.

Most competitor research falls apart at the comparison stage. You scan one store, learn something, scan another, and by the time you're looking at the second you've half-forgotten the first. You end up with two sets of notes and no clear read on how they actually differ. Putting two stores literally side by side fixes that — you see the contrast in one view instead of holding it in your head. This guide walks through how to do it well, with a worked example at the end you can copy.

What "comparing" two stores actually means

A useful store comparison isn't about which one looks nicer. It's about four concrete layers, each of which tells you something different:

Look at all four together and a store stops being a black box. You start to see the decisions behind it.

Paste two URLs and see the full breakdown in one view.

Running the comparison

The mechanics are simple. Open the comparison tool, paste one store into the Store A field and another into Store B (a full URL or just the domain both work), and hit Compare. Both stores are scanned at the same time, so it takes about the same 5–15 seconds as scanning one. You'll get back a single view with theme, apps, fonts and colours laid out in two columns, and the differences highlighted — apps unique to each store are called out, shared apps are grouped together, and mismatched themes are flagged.

When you find something worth keeping, use the "Copy share link" button. It produces a URL that re-runs the same comparison whenever anyone opens it — so you can drop it into a client email or a team channel and they'll see exactly what you saw.

How to read what comes back

Same theme, different results. If two competing stores both run Dawn but one clearly converts better, the theme isn't the difference — the apps, copy and offer are. That's a useful thing to rule out early.

An app on one side but not the other. This is the most actionable signal. If a competitor runs a subscription app and you don't, that's a revenue model you're leaving on the table. If they run a page builder and you rely on your theme's defaults, their landing pages are probably out-converting yours.

Apps they both run. Shared tools are the category standards. If every serious store in your niche uses the same email platform, that's the safe default — you don't need to agonise over the choice.

The theme is the canvas. The apps are the mechanics. If you only study one column, study the apps.

A worked example

Say you sell fitness apparel and you compare your store against a bigger competitor. Here's the kind of read you'd get, and what you'd do with it:

In five minutes you've gone from "they're doing better and I don't know why" to a ranked list of three things to test. That's the entire point of comparing rather than just browsing.

What a comparison can't tell you

Two honest limits. First, it shows what a store runs, not whether it's working — a store can install a reviews app and have it configured badly. Second, custom-coded functionality doesn't appear as an app, so a store that built its own system will look leaner than it is. Treat the comparison as a map of the stack, then use judgement about what the map means.
