“Only necessary” on Didomi, and six ad tags still fired
Ads tracking started before the banner was answered, carried on after “Only necessary”, and carried on again after we accepted and then withdrew.

What we saw
- Before any choiceGoogle Ads, Google Ads / DoubleClick, Google Ads conversion and 3 more were active 1.9 seconds after the page loaded.
- After “Only necessary”Meta Pixel, Google Ads, DoubleClick, Pinterest Tag and 2 more still sent requests.
- After withdrawingWe accepted, withdrew through “Update cookie settings” and “Disagree to all”, reloaded: the same six still sent requests.
Why it happened
The usual cause: ad tags that fire on every page view without checking the consent state, so all three choices end the same way.
How to fix it
- Gate the Meta, Pinterest and Google Ads tags on the marketing purpose in the consent tool.
- Set Google Consent Mode defaults to “denied” before any Google tag loads.
- Re-test all three paths: first visit, Reject, and withdraw after Accept.
Test Reject and withdrawal too. A banner can pass the first visit and fail both.
