Project 1: Roofing Services Dallas, TX

Stopping the Bleed on High CPCs

The Challenge

The client was bleeding budget on broad match terms like "how to fix a roof," paying $45+ per click with a Cost Per Acquisition (CPA) soaring above $350.

The Strategy

We instituted a massive negative keyword list (1,200+ terms), shifted to Exact/Phrase match for high-intent keywords like "emergency roof repair dallas," and implemented landing page CRO.

★★★★★
Verified Client Feedback

"They cut our wasted spend to absolutely zero within the first 30 days. The return on our ad spend is now completely measurable and highly profitable."

After: CPA (70% Decrease) $95.00
Conversion Rate 18.5%
ROAS Achieved 650%
Project 2: E-Commerce Los Angeles, CA

Scaling with Performance Max

The Challenge

Standard Google Shopping campaigns hit a plateau. ROAS was stuck at 200%, making it difficult to scale ad spend without losing profitability.

The Strategy

We optimized their Merchant Center feed with custom attributes, migrated top-performers to a segmented Performance Max (PMax) structure, and fed Google high-value audience signals.

★★★★★
Verified Client Feedback

"Transitioning to PMax with their custom feed optimizations changed everything for our brand. We scaled inventory without destroying our margins."

Project 3: HVAC Phoenix, AZ

Dominating the Heatwave

The Challenge

During peak Phoenix summers, ad costs skyrocket. The client couldn't maintain visibility during crucial afternoon hours when AC units fail most often.

The Strategy

We deployed Local Services Ads (LSAs) for top-of-page trust, combined with aggressive Search Ad bid modifiers based on live weather data and time-of-day parting.

★★★★★
Verified Client Feedback

"Our dispatchers couldn't keep up with the call volume. Adjusting bids based on the afternoon weather spikes was pure genius."

TB

Tom B.

Operations Manager

Campaign Performance

Before: Lead Volume/mo 45 Calls
After: Lead Volume/mo 210 Calls
CPA $38.50
Booked Jobs +360%
Project 4: Legal Services Miami, FL

Beating $150 CPCs

The Challenge

Personal Injury in Miami is ultra-competitive. The firm was paying $100-$150 per click for "car accident lawyer," resulting in an unsustainable $1,200 CPA.

The Strategy

We pivoted to long-tail, hyper-specific intent keywords, launched Spanish-language ad variations, and built high-converting, trust-focused landing pages.

★★★★★
Verified Client Feedback

"Getting our cost per case down to $340 in Miami seemed impossible against firms spending millions. Our retained cases have more than doubled."

Managing Partner

Campaign Performance

Before: Cost Per Case $1,200
After: Cost Per Case $340
Conversion Rate 22%
Retained Cases +140%
Project 5: B2B SaaS Austin, TX

Filtering Out the Junk Leads

The Challenge

Generating lots of form fills, but 80% were unqualified small businesses or students. The sales team was wasting valuable time.

The Strategy

Integrated offline conversion tracking via HubSpot to optimize Google Ads bidding strictly for MQLs/SQLs. Added firmographic exclusions.

★★★★★
Verified Client Feedback

"The quality of leads changed overnight. Our sales team is finally talking to actual decision-makers instead of students doing research."

Campaign Performance

Before: MQLs/mo 12
After: MQLs/mo 85
Lead Quality 92%

Project 6: Dental Surgery Chicago, IL

High-Ticket Consultations

The Challenge

Dental implants are high-value procedures. The clinic was getting standard teeth cleaning queries from broad ads instead of surgical consultations.

The Strategy

Age and income demographic layering. Created an "All-on-4" specific funnel with video testimonials and a clear financing CTA on the landing page.

★★★★★
Verified Client Feedback

"The shift from cheap cleanings to high-ticket implant consults transformed our practice economics. We've added an extra surgical day."

DS

Lead Surgeon

Campaign Performance

Before: Consults/mo 4
After: Consults/mo 38
CPA $185
ROAS 1200%
Project 7: Real Estate Denver, CO

Targeting High Net Worth Buyers

The Challenge

Broad real estate terms brought in apartment hunters and first-time buyers with budgets far below the agency's $1.5M+ listing average.

The Strategy

Targeted "Top 10%" income brackets, focused on specific luxury neighborhood keywords, and utilized Custom Intent audiences based on competitor luxury listings.

★★★★★
Verified Client Feedback

"We stopped wasting time on unqualified showings. The leads generated now are exclusively highly-qualified buyers ready to move on luxury properties."

Campaign Performance

Before: Cost/Lead $450
After: Cost/Lead $115
Showings +85%
Closed Deals 5/mo
Project 8: Automotive Atlanta, GA

Driving Actual Foot Traffic

The Challenge

Clicks were high, but showroom visits were stagnant. It was hard to attribute online ad spend directly to cars being sold on the lot.

The Strategy

Enabled Google Store Visits tracking. Ran localized Dynamic Search Ads showing live inventory counts. Bid heavier on mobile users within a 15-mile radius.

★★★★★
Verified Client Feedback

"Finally, we can actually measure how our digital spend translates to people walking onto the lot. Foot traffic has surged."

Campaign Performance

Before: Store Visits 120/mo
After: Store Visits 410/mo
Cost/Visit $22
Sales Vol +45%
Project 9: Home Services Seattle, WA

Maximizing Emergency Calls

The Challenge

Users dealing with a pest issue don't want to fill out forms; they want to talk to someone immediately. Landing page drop-off was huge.

The Strategy

Switched 80% of budget to Call-Only Ads on mobile devices. Setup dynamic routing to ensure ads only ran when dispatchers were available to answer.

★★★★★
Verified Client Feedback

"Shifting to call-only ads bypassed our leaky landing page entirely. Our phone rings off the hook during peak pest seasons now."

MT

Mike T.

Owner, NW Pest Control

Campaign Performance

Before: Calls/mo 50
After: Calls/mo 260
Call Rate 32%
CPA $18
Project 10: Cosmetic Surgery New York, NY

Overcoming Ad Compliance Issues

The Challenge

Google's strict healthcare policies were continually disapproving ads. CTR was abysmal, and the clinic was losing crucial market share in NYC.

The Strategy

Rewrote ad copy to be 100% policy-compliant while focusing on "board-certified" trust factors. Built a high-end funnel with before/after galleries directly on the landing page.

★★★★★
Verified Client Feedback

"We were locked out of Google Ads due to policy errors. They not only got us compliant, but built an ad funnel that completely revolutionized our lead generation."

AS

Clinic Director

Campaign Performance

Before: Revenue/mo $85,000
After: Revenue/mo $350,000
CTR 8.5%
