Question

After running Facebook retargeting ads through Shopify, we noticed returning users are seeing product pages without pricing or 'Buy Now' buttons. Could Shopify theme customizations be affecting ad traffic rendering?

Answer 1

Yes, Shopify theme customizations can absolutely affect how product pages render for users, especially those coming from Facebook retargeting ads.

Here’s what’s likely happening and how to fix it:

1. Theme-Based Conditional Rendering

   • Some Shopify themes or customizations use JavaScript to conditionally display price or buttons based on visitor type, geolocation, or referrer.

   • Users coming from Facebook may have UTM parameters or cookies that interfere with how the theme loads elements.

2. Deferred Content Loading

   • Themes that lazy-load pricing or buttons (especially with custom scripts) may break if:

     • The page loads too fast or slow

     • Third-party tracking scripts (like Meta Pixel) interrupt execution

3. App Conflicts or Script Errors

   • Retargeting users might trigger different app behaviors (popups, timers, dynamic offers) that conflict with button or price rendering.

4. Ad Blockers or Browser Behavior

   • Some browsers, particularly on iOS or with Facebook in-app browsers, block JavaScript or cookies, which may prevent the full product page from rendering properly.

How to Fix It

• Test with UTM parameters: Manually load a product page with Facebook UTM codes to replicate the issue.

• Check browser console for JavaScript errors.

• Review theme.liquid and product.liquid for any conditional logic affecting button or price display.

• Disable third-party popups or discount scripts temporarily and test again.

If needed, isolate the theme issue using a fresh, uncustomized theme copy for testing.
