Google Ads Case Study

PhysiotherapyAI vs Agency

What actually happened when a physiotherapy clinic's Google Ads account changed hands from a traditional agency to AI-led management. Same account, same offer, same market.

Industry
Physiotherapy
Market
Kingston upon Thames
Period
May–Aug 2026
01 · The setup

One campaign, two managers

No rebuild, no reset, no new account. The exact same Search campaign, targeting the exact same offer, only the manager changed.

11 May

Campaign built and launched by the clinic's agency. Within weeks it becomes the account's best-performing campaign.

24 Jun
Flagged in writing

A routine review flags the campaign is under-budgeted for its own results, and lists specific keyword gaps letting budget leak to the wrong searches.

24 Jun–12 Jul

Three weeks pass. The agency retains full access. None of the flagged gaps are closed. (More: page 4.)

13 Jul
Handover

Management moves to AI. Same campaign ID, same budget, same offer, the only variable that changes is who's watching it.

02 · The result

Cost per lead held steady through the handover

Fifteen straight weeks, including August, the seasonally slowest month for physiotherapy (school holidays). No cliff, no spike, at the point the manager changed.

03 · What actually changed

Flagged in writing. Fixed the day it changed hands.

The performance held steady, but the account underneath it got healthier. This is what "AI-managed" meant, on the exact campaign in the chart above.

Physiotherapy SearchThe campaign above
1

24 Jun: Flagged in writing, under-budgeted, with named competitor and NHS/hospital search terms leaking spend.

2

24 Jun–12 Jul: Three weeks, full access. None of it actioned.

3

13 Jul: Handover day. 87 protective keywords added, closing every gap flagged three weeks earlier.

04 · What the agency was also running

Real spend. Zero bookings.

Alongside the Search campaigns, the agency ran two additional campaigns on a different ad format. Both are now retired.

05 · The actual ROI

Same ad performance. No monthly fee.

If the ad results are comparable, the real difference isn't in the ad account, it's in what stops leaving your bank account every month.

From £2,500
One-time. No retainer, no lock-in, the account is yours
  • Pays for itself in under 6 months, then every month after is money you're not paying an agency.
  • You own the setup, not the relationship. Once it's built, there's nothing further to pay to keep it running.
Curious what this looks like for your clinic

Is your account leaving something on the table?

Most clinics have never seen exactly what their agency is (or isn't) doing with their budget. A short call is usually enough to find out.
