FAQ
General Questions
Section titled “General Questions”What is Heureka conversion tracking?
Conversion tracking allows you to monitor how many customers from Heureka actually made a purchase in your e-shop. This data helps you:
- Analyze advertising effectiveness on Heureka
- Optimize campaigns
- Measure ROI (return on investment)
Which key should I use?
Use the public key from the Heureka administration. This key is safe to use in JavaScript because it only serves to identify your e-shop.
Never use the private key in public code.
Does the module support Slovak Heureka?
Yes. Select “SK” in the settings and use the key from heureka.sk.
Where can I find conversion statistics?
You can find statistics in the Heureka administration:
- Log in to sluzby.heureka.cz
- Select your e-shop
- Go to the “Conversion Tracking” or “Statistics” section
Technical Questions
Section titled “Technical Questions”Where is the tracking code displayed?
The tracking code is displayed in two places:
- Thank you page - after order completion
- Product page - for tracking product views
What data is transmitted?
On the thank you page, the following is sent:
- Order ID
- Products (ID, name, price including VAT, quantity)
- Shipping and fees
- Total price including VAT
- Currency
On the product page, only the tracking script is loaded without additional data.
Does the module work with cache plugins?
Warning: Full-page cache may cause problems on the thank you page. The thank you page should be excluded from caching.
Most cache plugins automatically exclude WooCommerce pages, but verify this in your cache plugin settings.
Can I modify the tracking script URL?
Yes. Use the wpify_woo_heureka_mereni_konverzi_url filter:
add_filter( 'wpify_woo_heureka_mereni_konverzi_url', function( $url ) { // Custom logic return $url;} );Why are conversions not showing on mobile?
The module works the same on all devices. If conversions are not showing:
- Check if the thank you page loads correctly
- Verify that the mobile browser is not blocking JavaScript
- Check if you have an active adBlocker
How do I test if tracking is working?
- Complete a test order
- On the thank you page, open the browser console (F12)
- Check:
- No JavaScript errors
- The Network tab should show a call to heureka.cz
- The source code should contain the tracking script
Does the module affect e-shop speed?
The module has minimal performance impact:
- The tracking script loads asynchronously
- One API call is made on the thank you page
- The Heureka script is hosted on their CDN
