Key Compliance & Technical Observations
1. Lack of Consent Approach
We see that 2 brands have no approach to consent tracking, completely omitting a consent banner or modern verification framework. This signals the highest privacy risk vector to their digital operations under UK law.
2. The "Next Page" Firing Lag
There is plenty of evidence of bad CMP configuration, where marketing tags fail to execute immediately when a user engages the main cookie banner "Accept" selection. Instead, this requires the user to navigate a brand new page route or subsequent refresh fires to trigger. This creates a big hole in both analytics & advertising tracking, especially if the user bounces.
3. Pre-Consent Firing
Exactly 50.0% of the brands evaluated continue to deploy some form of non-essential marketing pixels prior to any form of user interface interaction with the CMP banner. Under explicit PECR guidance, dropping tracking mechanisms before a clean opt-in is a big red flag.
4. Post-Decline Tracking Leaks
For 43.3% of audited sites, clicking "Reject All" fails to stop tag deployment. Again this points to badly configured CMP + Tag Manager setups, where you'd expect the action of rejecting cookies to actually work.
5. Martech Usage
Quite a lot of brands are using OneTrust as their primary CMP vs a more custom approach, alongside GTM for tag management vs enterprise Tealium. Only a couple actively have an mature approach to ad tracking that involves 1st party domains & server side tracking, leaving a lot on the table.
