How WP Rocket works with Product Feed Pro

Running WP Rocket on a WooCommerce store is a smart performance move, but it’s natural to wonder whether a caching plugin can interfere with your product feeds. The good news is that Product Feed Pro and WP Rocket work well together — feed generation is entirely server-side and caching never touches your feed files. There’s one specific scenario to check: if you use the Facebook Pixel Add to Cart tracking feature, and you have WP Rocket’s Delay JavaScript execution enabled, you’ll need to add one exclusion. This article walks you through it.

How feed generation works with WP Rocket active

Product Feed Pro generates your feeds as static XML, CSV, or text files and stores them in your site’s uploads folder (at wp-content/uploads/woo-product-feed-pro/). When a channel like Google Shopping or Facebook Catalog fetches your feed, your web server delivers the file directly — no WordPress page request is involved, so WP Rocket’s page cache plays no part.

Feed schedules run through Action Scheduler on the server. They run independently of whether the page is served from cache. So automatic feed refreshes continue to work as normal.

All admin actions in Product Feed — including creating feeds, manually refreshing them, and adjusting settings — use WordPress’s admin AJAX endpoint. WP Rocket does not apply its optimisations to the WordPress admin area, so the admin panel works normally.

When WP Rocket is active, Product Feed Pro automatically registers your feed URLs as preload exclusions on WP Rocket’s side — no manual configuration needed. This prevents WP Rocket from preloading the (potentially large) feed files.

Check Delay JavaScript execution if you use Facebook Pixel

The only area where WP Rocket can affect Product Feed Pro is the Facebook Pixel feature. When you enable Add Facebook Pixel in Product Feed → Settings, the plugin loads a small script (woosea_add_cart.js) on your storefront. This script fires the Add to Cart event so Facebook can track shoppers as they add items to their cart.

WP Rocket’s Delay JavaScript execution feature holds all JavaScript until a shopper interacts with the page. If this is active and woosea_add_cart.js isn’t excluded, the Add to Cart event fires only after the first user interaction — meaning some events may not be tracked at all.

How to exclude the script

1. Go to Settings → WP Rocket in your WordPress admin.
2. Open the File Optimization tab.
3. Scroll to the Delay JavaScript execution section.
4. Find the Excluded JavaScript Files field and add woosea_add_cart.js on a new line.
5. Click Save Changes.

You only need this step if you have the Add Facebook Pixel checkbox enabled in Product Feed → Settings. If you don’t use the Facebook Pixel feature, no WP Rocket configuration changes are needed.
