Previous Agency Stagnation
Parthenon Dental is an established San Mateo practice that came to Spartan SEM from a previous agency focused on dentists that kept the website online but let the practice’s online growth stall. The foundation was there; the momentum wasn’t.
Three problems were holding them back:
- Stagnant growth. The prior agency maintained the site, but rankings and traffic had flatlined. No upward trajectory to speak of.
- Untapped local demand. In a competitive San Mateo market, Parthenon wasn’t capturing the patients actively searching for a dentist.
- No immediate lead flow. With everything riding on slow-moving organic, there was no paid channel bringing in patients in the meantime.
The Work: SEO That Compounds, Paid That Delivers Now
We built a three-channel program designed to fix both problems at once: restart durable organic growth while adding paid channels that bring patients in immediately.
SEO for durable, compounding growth.
We rebuilt the content and technical foundation around the San Mateo dental terms that bring in patients, moving the practice off its plateau and onto a steady upward climb in rankings and organic traffic.
Google Ads for immediate reach.
Paid search put Parthenon in front of high-intent searchers from day one, delivering booked patients while organic gained ground.
Local Service Ads for pre-qualified local leads.
Google’s Local Service Ads – the “Google Guaranteed” units above the map pack – added a stream of pre-qualified local leads on a pay-per-lead basis, giving the practice another immediate, high-intent source of new patients.
The Data: Solid, Consistent Growth
Comparing the last three months to the prior three, growth shows up across every channel. Organic building steadily while paid delivers from the start:
| Metric | Before | After | Growth |
|---|---|---|---|
| Keywords ranking* | 0 | 169 | New |
| Keywords in top 3* | 0 | 10 | New |
| Organic sessions | 264 | 873 | +231% |
| Google search clicks | 308 | 601 | +95% |
| Google search impressions | 34,200 | 82,000 | +140% |
| Total conversions (calls & forms) | 42 | 212 | +405% |
| Organic conversions | 24 | 87 | +263% |
| Paid Search conversions | 0 | 39 | New |
* Keyword counts are from SEMrush, reflecting growth since the campaign launched Feb 1, 2026. Sessions, clicks, impressions, and conversions compare the last 3 months to the prior 3 months via GA4 and Search Console.
The shape of this growth matters as much as the size. Organic sessions up 231% and traffic roughly tripling reflect a continual, compounding climb. 169 keywords are now ranking, with 10 in the top 3, and 38 more in positions 4–10 poised to follow, rather than a one-time spike. On top of that steady growth, the newly added paid channels lifted total conversions 405% (42 → 212), delivering patients immediately while SEO does the long-term work.
How the Strategy Works
This is what a healthy, sustainable campaign looks like for a practice starting from an established but stalled base. SEO compounds – every month of rankings and content builds on the last, so the organic curve keeps bending upward. Paid search and Local Service Ads sit alongside it, delivering patients now and smoothing the ramp so growth never has to wait on organic alone.
The result is steady, above-average momentum: a practice that was flat is now growing across every channel, with the organic engine set up to carry more of the load over time.
