Google Consent Mode v2 · diagnostics

Your ads can be running while your data quietly disappears.

When a site's tracking tags fire without a proper consent signal, Google drops or models the conversion data for EU and UK visitors instead of measuring it. The site looks fine. The dashboard looks fine. The numbers are wrong — and you can't get the lost data back.

The finding

We scanned 100 newly-launched AI-built sites. Not one had it set up correctly.

Of the 100, only 34 were running a Google tag at all. Among those 34 — the ones actually investing in tracking and ads — here's what we found, read directly from each site's network requests and confirmed by hand.

Sample: 100 sites, 34 running Google tags. Indicative, not a market-wide figure. Verified by hand, not by tool alone.

Why it's invisible

A consent banner can look perfect and still fail silently.

01

The banner is cosmetic

Plenty of sites show a tidy "Accept" banner that was never wired to the tags. You click Accept, and the consent signal still goes out uninitialised.

02

Nothing breaks visibly

The page loads, the ads run, customers still buy. Only the measurement degrades — so the failure hides in your Google Ads dashboard as "fewer conversions," not an error.

03

The loss is permanent

Conversions that weren't measured with valid consent aren't recovered later. Every day it runs broken is data you don't get back — and remarketing audiences that never fill up.
