Spine Center of Louisiana

A multi-location spine surgery practice with 5 locations across Louisiana, specializing in minimally invasive spinal fusion surgery. They needed a Google Ads campaign to generate qualified patient leads in the Baton Rouge market immediately, even while their website was mid-rebuild.

What we inherited

The campaign launched with structural problems that choked performance from day one. Here's what we found on intake.

Bid Cap Choking Auctions

$12 Max CPC bid cap was losing 27.65% of impression share to rank. The campaign was showing "Eligible (Limited)" status.

🔍

Narrow Keyword Set

Only 12 keywords, all variations of "minimally invasive." Three exact match keywords were dead on arrival with zero local volume.

📊

Zero Ad Extensions

No sitelinks, no callouts, no call extension, no structured snippets. The ads were running bare with no supporting assets.

🚨

Broken Conversion Tracking

Form submission tracking was broken at launch. No GHL call import. The only signal was a GA4 phone click event.

🏗

Website Mid-Rebuild

All traffic pointed to a single existing page on a site that was 2 months from launching its new design. No custom landing page.

Severe Underspend

$67/day budget was only spending $9.11/day average. The campaign was crawling when it should have been sprinting.

5 weeks. One ad group. Total transformation.

Every metric moved in the right direction. Here's what the numbers looked like at peak performance versus the baseline we inherited.

The optimization timeline

Every change was surgical. One ad group, one RSA, one landing page. Here's exactly what we did and when.

March 6 — Campaign Intake
Diagnosed the bottleneck: rank, not budget
The $12 Max CPC bid cap was strangling the campaign. Only spending $9.11/day on a $67/day budget. Three keywords were dead. Zero ad extensions running. Expected CTR was scoring "Below average."
March 20 — Keyword Expansion + Bid Fix
Added 12 broader keywords, raised bid cap to $20
Expanded beyond "minimally invasive" into "spine surgery," "back surgery," "spinal fusion," and surgeon-intent terms. Built comprehensive negative keyword blocks across two waves. Pinned headline #1 and added three keyword-relevant headlines to the RSA.
March 27 — Ad Extension Buildout
Deployed 4 sitelinks, 4 callouts, call extension
Added "Our Spine Surgeons" (12.44% CTR), "Patient Reviews" (13.13% CTR), "5 Louisiana Locations" (11.58% CTR), and "Request an Appointment" sitelinks. Call extension alone generated 36 clicks at 13.19% CTR.
April 3-9 — Peak Performance Week
71 conversions. 190 calls. Zero missed.
11.59% CTR. $6.66 CPA. 79.8% conversion rate. Zero visible competitors in auction insights. The campaign hit full stride with every optimization compounding on the last.

One keyword we added changed everything

Top Performing Keyword
"back surgeon"
This keyword wasn't in the original campaign. It was added during the March 20 expansion as a phrase match term. By Week 5, it was responsible for 79% of all conversions, pulling in 72 clicks from 518 impressions at a 13.90% CTR.

Cost per lead: 95% below industry average

Spine surgery Google Ads campaigns typically run $150 to $300+ per lead. This campaign produced qualified spine surgery leads at $6.66 each. That's a 95%+ reduction from what practices normally pay, achieved on a $67/day budget with a single landing page that was part of a website mid-rebuild. The campaign was never given a budget increase, meaning it never ran at full capacity.
