The Challenge

Auto repair is one of the most competitive local search verticals in Houston. When a car owner searches “mechanic near me,” dozens of shops bid for the same click. Duggy’s needed to compete for general repair traffic while also capturing the niche 4x4 enthusiast market. Before INFINI, the account had structural issues:
Conversion tracking broken — 6 competing actions including duplicates, wrong categories, and Local Action signals poisoning Smart Bidding.
No first-time vs. repeat caller distinction — the bidder couldn’t tell new prospects from existing customers.
Budget capping impression share at 48% — 1 in 3 eligible searches skipped every day.
ShopGenie booking integration not verified across all landing pages.
No negative keyword program — spend leaking to DIY queries, parts searches, career terms.
The performance wasn’t bad — the foundation was leaking. Fix the tracking, clean the signal, and the same budget produces dramatically better results.

What INFINI Built

Conversion Tracking Remediation

INFINI audited every conversion action and made one decisive change: First Time Phone Call became the sole primary biddable signal. Duplicate call actions were removed, Local Action conversions were demoted, and ShopGenie bookings and form submissions were kept as secondary signals. For the first time, Smart Bidding could learn from clean data.

The Core Transformation
From signal chaos → one true conversion + supporting context

Google Ads — Search Campaigns

Search campaigns target auto repair, oil change, brake repair, transmission, engine diagnostics, and off-road/lift kit services. Separate ad groups for general repair vs. off-road specialty ensure each audience sees relevant copy. Bidding: Maximize Conversions with Target CPA guardrails.

CallRail Integration + Negative Keyword Program

CallRail tracks every inbound call with source attribution and quality tags (“Schedule Requested” / “Schedule Booked”). A monthly negative keyword scrub catches wasted spend — $123/month eliminated in the first pass on terms like “spoiler installation” and “car place near me.”

Potential upside

Double budget ≈ double calls
Duggy’s is showing up for only half the eligible searches. The 34% lost to budget is not a quality problem — the ads win their auctions. Google stops serving them because the daily budget runs out. At $33.80 CPA (55% below benchmark), doubling the budget from $1,285 to $2,500/month would roughly double paid call volume while maintaining cost efficiency.
