A Paris oral surgeon lost her biggest keyword and moved offices. Traffic went up 88% anyway.
Dr Solene Vo Quang runs a single-practitioner stomatology practice in Paris. In four months her estimated organic traffic went from 4,203 to 7,921 monthly visits, through an office move that reset her map rankings and the loss of a 40,500-searches-a-month keyword. This is what an acquisition system that does not depend on one keyword looks like.
A respected surgeon, fully dependent on one keyword and one map pin
Dr Vo Quang is a chirurgienne-stomatologue with a strong reputation: conference speaker, medical press, 20,000 LinkedIn followers. Her online acquisition told a different story. Nearly one fifth of all site traffic hung on a single keyword, and her local visibility hung on a single Google Business Profile.
Then the hardest possible test arrived on the calendar: a full office move across Paris on July 1, the one event known to reset local rankings.
Survive the move, then stop depending on luck
An address transfer wipes the local map history that took years to build. On July 16, two weeks after the move, the practice averaged position 80+ on its own core term across a 25-point map grid, with 19 of 25 measurement points showing no presence at all.
A practice in that position is one algorithm update, or one competitor, away from an empty schedule. The job was not just recovery. It was making sure no single point of failure could ever do this again.
What the practice looked like in May 2026
Four moves, each removing a single point of failure
Build the long tail before it was needed
One page per condition and procedure, written to answer one real patient question each. The keyword base grew from 835 tracked terms in July to 1,231 in August, so no single term could sink the site.
Manage the office move as a project, not an accident
Address data, Google Business Profile, reviews and citations migrated in a controlled sequence, then tracked weekly on a 25-point map grid until the local pack came back.
Make the content citable by AI assistants
Pages written as self-contained statements with a condition, a place and an outcome. The practice now appears in Gemini and Perplexity answers for its procedures, screenshots below.
Drive ads on cost per identified contact, not clicks
Campaigns optimized against contacts with a name, a phone number and a stated reason for the call. That cost fell from 75 EUR at launch to 39.78 in July to 23.87 in August, at an 8.47% conversion rate.
Four months, measured

| Metric | May | June | July | August | Change |
|---|---|---|---|---|---|
| Estimated organic traffic (visits/month) | 4,203 | 4,514 | 7,557 | 7,921 | +88% |
| Keywords in position #1 | 97 | 144 | 189 | 243 | 2.5x |
| Keywords in top 3 | 153 | 228 | 310 | 365 | 2.4x |
| Keywords in top 10 | 291 | 412 | 604 | 693 | 2.4x |
| Authority Score (Semrush) | 10 | 11 | 11 | 12 | +2 |
| Cost per identified Ads contact | 75 EUR at launch | - | 39.78 EUR | 23.87 EUR | divided by 3 |
The stress test: losing 1,417 visits in a month, and growing anyway
In August the practice's biggest keyword, "stomatologue" at 40,500 searches a month, dropped out of the tracked rankings as the last ripple of the address move. It had carried 1,417 visits, almost a fifth of all traffic. Total traffic still rose, from 7,557 to 7,921, absorbed by 396 newly ranked keywords. Three months earlier, the same event would have collapsed the practice's visibility. This is the difference between ranking for a keyword and owning an acquisition system.

Cited by AI assistants, not just ranked by Google
Patients increasingly ask an assistant instead of searching. Pages built as self-contained, citable statements got the practice named in generative answers, a channel that did not exist for it before.

About this case
How fast did local SEO recover after the office move?
The address transfer on July 1, 2026 reset the map rankings. On July 16 the practice averaged beyond position 80 on its core term. On August 11, one month later and one month ahead of the announced recovery date, the average was 12.6 with no dead points on the 25-point grid.
How did traffic grow 88% while the biggest keyword was lost?
Between May and August the site went from 291 to 693 keywords in the top 10. When "stomatologue" and its 1,417 monthly visits dropped out, 396 newly ranked keywords absorbed the loss and total traffic still rose from 7,557 to 7,921 estimated visits.
What does patient acquisition cost with ads in this specialty?
For this Paris oral-surgery practice, the cost per identified contact, meaning a name, a phone number and a stated reason, fell from about 75 EUR at launch to 39.78 in July to 23.87 in August 2026, at an 8.47% conversion rate.
Is this repeatable for another single-practitioner clinic?
The mechanism is: a broad keyword base instead of one hero term, a managed Google Business Profile, ads optimized on identified contacts, and content assistants can cite. The mechanism transfers. The exact figures depend on the market and the starting point.
