Retargeting Pixels
Coming soon — Pro and Business plans.
Retargeting pixels let you automatically add QR code scanners to your Meta (Facebook/Instagram) and Google Ads retargeting audiences — without any changes to your destination website.
How it works
Normally, retargeting pixels are placed on the destination website. With Stirling-QR's pixel feature, the pixel fires on an intermediate page during the redirect — before the user arrives at your site. This means you can retarget QR code scanners even if you have no access to the destination site's code.
Setting up a Meta Pixel
When creating or editing a QR code, expand 'Tracking Pixels'. Enter your Meta Pixel ID (found in Meta Events Manager). Every time someone scans the code, a PageView event fires for your pixel. You can then create retargeting audiences in Meta Ads Manager using this event.
Setting up Google Ads conversion tracking
Enter your Google Ads Conversion ID (format: AW-XXXXXXXXX) and Conversion Label. Scans will be recorded as conversion events in your Google Ads account, enabling Smart Bidding optimisation and retargeting audiences.
Privacy considerations
Before enabling retargeting pixels, ensure your QR code's use case complies with GDPR, CCPA, and the destination platform's terms. Pixels should only be used where users have consented to tracking. Consider adding a privacy notice to your destination landing page.
💡 Pro Tips
- Use Meta Pixel with QR codes on physical packaging to retarget shoppers who scanned in-store but didn't purchase online.
- Combine retargeting pixels with UTM parameters (Google Analytics integration) for a complete picture of your QR scan attribution.
