Custom Integration with Klaviyo Not Showing Data: Need Help with 'Viewed Product' Tracking

Hey @it magic,

Thanks for providing an update in the Community!

Just to provide some clarity on what the issue may have been for other Community members. In my experience, this is common if after adding the code, the browser you’re testing on has not been cookied. 

It’s also important to note that the event will only track cookied users who visit the product page. Additionally, it would only track users since they’ve been cookied and does not retroactively record product pages viewed prior. 

When testing, we suggest taking the steps below as mentioned in our Troubleshooting viewed product tracking Help Center article:

Test Viewed Product tracking

To test that your Viewed Product tracking is set up properly, follow these steps:

1. Navigate to your website
2. On your homepage, add the following to the end of the URL, replacing testing.email@gmail.com with your email address:
   ?utm_email=testing.email@gmail.com
   
3. Reload the page
4. Navigate to a product page on your site
5. Search in Klaviyo for your email address
   

You should see that a Klaviyo profile has been created for you (if one didn't exist already) and that this product view has been tracked on your activity feed.

To see a feed of all Viewed Product metrics over time:

1. Click the Analytics dropdown in Klaviyo and select Metrics
2. Filter by Viewed Product to view tracked data in an activity feed, activity map, charts, best people, and cohort reports
   

Once you’ve reviewed the troubleshooting scenarios below and made changes, you should test your tracking again to make sure it’s working correctly. 

Thanks for being a part of the Klaviyo Community!
