Commerce starts with Add to Cart
Atchoo A/B tests your Shopify product page templates so you can see which layout pushes shoppers to take that first step. Track it live, decide with data, ship the winner.
Live in five minutes
Atchoo uses Shopify's own template system, so your variants live inside your existing theme.
Create a variant template
Duplicate your product template in the theme editor and change what you want to test: layout, images, copy, the Add to Cart button. No code.
Start the test
Pick the products, pick the templates, hit start. Atchoo splits traffic 50/50 and every visitor consistently sees the same version.
Ship the winner
Watch Add to Cart rates side by side with Bayesian analysis that tells you how confident you can be, then roll out the template that wins.
Everything points at one number
Add to Cart rate is the cleanest signal a product page controls. Atchoo is built around it.
Watch Add to Cart happen, live
Every product view and Add to Cart flows into Atchoo in real time, split by template and traffic source. You see which layout earns the click, not a guess about it.
A winner you can trust
Bayesian analysis turns raw counts into a plain answer: the probability your challenger genuinely beats the control. No p-value gymnastics, no calling it early on a lucky afternoon.
Run template tests without a developer
Build a variant of your product template in the Shopify editor, pick your products, and start. Atchoo handles the traffic split and the measurement. Nothing is duplicated, nothing drifts.
Testing that respects your storefront
Most tools tax your store to run a test. Atchoo was designed not to.
No theme duplication
Theme-split tools copy your whole theme, so every later edit risks the copies drifting apart. Atchoo tests templates inside your one live theme.
No storewide flicker
Anti-flicker is scoped to product pages with an active test only, reveals the moment the variant is decided, and has a hard failsafe. The rest of your store is untouched.
First-party tracking
Events run through Shopify's app proxy on your own domain. No third-party cookies, no external tag managers slowing pages down.
A metric you can act on
Add to Cart rate in real time, segmented by traffic source, so you always know what a change actually did.
Consistent by visitor
Each visitor is bucketed by a stable first-party ID and always sees the same variant, so the experience never flips between page views and your data stays clean.
Results you can read
Bayesian analysis reports the probability that your variant genuinely beats the control, which is far easier to act on than a raw p-value.
