Meet the Client
A UK-based tutoring crew on a mission
This UK-based tutoring crew is on a mission to make learning feel less like a chore and more like an adventure. But it’s not just about cramming — they also teach languages in a way that sticks, mixing lessons with culture, conversation, and even the occasional school trip.
Whether it’s boosting grades or learning to speak like a local, they keep things smart, personal, and never boring. And when their Google Ads data suddenly fell off a cliff, they needed answers — fast.
The Alert
Google Ads fired a conversion tracking warning
When the alert came through, we jumped in immediately. Our first priority was to determine whether this was a tracking malfunction or something deeper. The answer turned out to be both — and neither what the client expected.
UK campaign clicks dropped from 1,200 to 132 — an 89% collapse in a single period
Impressions fell from 43,000 to 2,700 — a 93.7% drop with no obvious campaign change
GA4 UK pageviews fell from 1,481 to 260 — a 93% drop mirroring the Ads data
No tracking errors were reported — making the root cause far less obvious than expected
Our Approach
Audit first. Conclusions second.
We ran a full technical audit across GA4 and Google Ads before drawing any conclusions. The goal was to eliminate tracking as the cause — and then look elsewhere for the real answer.
✅ Full Technical Audit — Result: All Clear
- All events tracked correctly across GA4 and Google Ads
- No duplication or misfires detected anywhere in the setup
- Complete and clean data flow confirmed end-to-end
Conclusion: Tracking systems are functioning properly. There is no technical malfunction.
Performance comparison: two equal 13-day periods
With tracking ruled out, we compared two back-to-back 13-day periods — before and after the performance drop — across both Google Ads and GA4.

What We Found
Root cause of the drop
With tracking clean and the data telling a clear story, the investigation pointed to two compounding causes — one being a definitive compliance failure, the other a likely campaign-side shift requiring internal review.
🔒 Missing Cookie Consent (GDPR)
- UK users fall under GDPR regulations
- The site did not show a cookie consent banner to UK visitors
- Without consent, Google Ads and GA4 tracking was blocked entirely
- This directly caused both the data disappearance and the ad delivery collapse
📢 Potential Ad Delivery Disruptions
- Campaigns may have experienced reduced reach or impressions
- Budget reallocations or pauses post May 9 were possible
- Narrowed geo or audience targeting could explain the scale of the drop
- Recommended reviewing all campaign settings for UK post May 9
Our Recommendations
Immediate, actionable next steps
Armed with a clear diagnosis, we delivered two concrete recommendations — one urgent technical fix and one internal process review — so the client could act confidently and recover UK performance.
Implement Cookie Consent Immediately
- Deploy a GDPR-compliant cookie banner specifically for UK users
- Without this, Google will continue limiting tracking and remarketing
- Directly impacts both performance and reporting accuracy
- This is the single highest-priority fix to restore UK data flow
Align with the Marketing Team
- Review campaign delivery status around the May 9 drop date
- Check for any geo-targeting or audience changes made at that time
- Audit budget or bidding strategy adjustments for UK campaigns
- Rules out campaign-side causes and confirms the full picture
The Takeaway
Not a tracking failure — a privacy compliance gap
This was not a tracking failure — it was a privacy compliance issue and potentially an ad delivery shift. By running a structured audit and comparing the data, we delivered exactly what the client needed: clarity, confidence, and a clear path forward.
Tracking Validated
Clear confirmation that all tracking was functioning correctly — no technical malfunction
Root Cause Found
Missing GDPR cookie consent banner identified as the primary cause of the UK data collapse
Actionable Steps Delivered
Immediate, prioritised recommendations so the team could recover UK performance with confidence
Now that the problem is identified, the team can confidently take action to recover performance in the UK market. This was not about broken tracking — it was about a missing consent banner silently shutting down visibility for an entire country.
