At ABConvert, we help Shopify merchants run A/B tests by tracking key user events like Add to Cart, Checkout, and Page Views. These events are typically collected through client-side Shopify Web Pixels.
What happens when users decline cookies?
However, due to Shopify’s privacy policies and global data protection laws (such as GDPR, CCPA), if a visitor denies cookie consent in the store’s privacy banner, Shopify will automatically block tracking pixels. Which means:
Add to Cart events
Checkout events
Page View events
These events will not be tracked if the a visitor denies cookie consent.
How to handle this in your A/B test analysis?
If some users decline cookies, their actions (like adding to cart or checkout) will not be counted in the test results. However, order count remains 100% accurate because it is tracked directly from Shopify’s server-side webhook, which is not affected by cookie consent settings.
What should you focus on?
If you’re concerned about missing event data due to privacy settings, we recommend focusing on:
✔ Order count – Tracked through Shopify’s server-side webhook
✔ Revenue metrics – Compare AOV (average order value) and total revenue
These numbers are not impacted by Shopify’s tracking restrictions.
