CookieChest watches CMP, GTM, Consent Mode and GA4 across every site in your portfolio. The moment one breaks, you get an email — not a panicked Monday call from your client.
Billed annually · 30-day money-back guarantee · Reassign slots any time
Tracking failures don't announce themselves. They sit quietly in your client's GTM container until they become your problem.
Friday afternoon a developer pushes a release. By Monday your client emails: “leads have dropped — what’s happening?” You scramble to check tracking. Three days of conversion data are already gone.
Consent Mode misfires after a CMP update. Google Ads can’t see conversions. Smart Bidding starves the campaign — and even after you fix it, performance takes a fortnight to recover.
A dev pushes an untested update. GTM stops firing. We catch it inside 6 hours — not the next retainer review. One incident like that pays the slot for years.
We scan UK sites across multiple sectors and consent platforms — all running paid advertising. The majority had GA4 failing to fire when the visitor accepted cookies. Most of the agency reporting they pay for, quietly broken on the day we found it.
A £10k/week campaign running blind for four days = £5,700 in untracked spend, two weeks of Smart Bidding recovery, and a client conversation you didn't need to have. At £71/slot/month, one prevented incident pays for the slot for six and a half years.
The alert finds you — no dashboard babysitting required. A specific email, with the receipts to show your client.
One slot, one site. Client leaves mid-year? Reassign the slot to the new client — no extra cost, no leftover commitment.
