MASSIVE Discrepancy Between Page Views and Product Detail Views

Data collection and tags

Hello,

I’ve got site that combines information from two sites, www.crimsoncup.com (wordpress) and shop.crimsoncup.com (Shopify). Until two weeks ago, the Piwik Pro snippet was served the same way on both sites. Two weeks ago, I switched the Shopify site to place the PP snippet into a customer event pixel (Shopify: install a tracking code | Piwik PRO help center).

Since doing that, the product detail views number has remained consistent but the page views number for shop.crimsoncup.com has dropped significantly. Here are the numbers for one product:

four weeks ago (Feb 3 - Feb 9):
page views - 87
product detail views - 89

three weeks ago (Feb 10 - Feb 16):
TRACKING CHANGE MADE on Feb 11
page views - 67
product detail views - 69

two weeks ago (Feb 17 - Feb 23):
page views - 36
product detail views - 83

last week (Feb 24 - Mar 2):
page views - 16
product detail views - 90

Hi David,

We’ve performed a quick investigation into this issue, and here’s the conclusions:

  1. The solution from the help center should work correctly. I created a shop via Shopify and connected a custom pixel to it according to the help center instructions. Everything looks fine and performs as expected.
  2. I checked the customer’s shop webpage, and it seems that product pages always trigger both page view and product view events, which is expected.

Could you confirm whether the issue is still present? If so, more information is needed:

  1. Are there any broken events caused by requests from the shop webpage?
  2. Is the custom pixel configured correctly?
  3. How are the custom pixel privacy settings configured?

We are also working on a Piwik PRO Analytics application for Shopify. It is an early version, not yet published in the Shopify App Store, but it is available for installation via this link: Piwik PRO Analytics - A flexible analytics suite for marketers and analysts. | Shopify App Store.

Best,
Oliwer

The huge difference continued BUT I have discovered the problem. I had been tracking pageviews for specific pages doing an exact match. On the day that I moved GA4 to the Google/YouTube pixel, GA4 started decorating all sessions across the two subdomains with “_gl=XXXXXXXXXXXXX”

Once I changed my report filtering, I see that all page views are there.

Still, this very strange behavior from GA4 that could be tripping up other Piwik Pro users too, depending how strict their filtering is for certain pages!
