How We Cut CPA by 60% While Doubling Conversions — On Half the Budget

Dumpster Rental Dogs came to us burning through ad spend with rising costs and stagnant conversion rates. In six months, we restructured their entire Google Ads account, slashed wasted spend, and nearly doubled their conversion rate — all while cutting their budget in half.

A Business Bleeding Ad Spend with No Direction

Dumpster Rental Dogs had the right product, competitive pricing, and genuine demand in their local markets — but their Google Ads account was hemorrhaging budget with nothing to show for it.

⚠️

The Challenges

  • Broad match keywords triggering irrelevant searches, wasting 40%+ of budget on non-converting traffic
  • No negative keyword strategy — ads showing for competitor brand terms and completely unrelated queries
  • Single landing page with no segmentation by market, dumpster size, or use-case (residential vs. commercial)
  • Cost per conversion had climbed to $185+ and was rising month over month with no optimization in place
  • Geographic targeting was unfocused — running nationally with no local intent signals or market prioritization
  • Zero conversion tracking for phone calls, which represented 65% of actual bookings
✓

Our Strategic Approach

  • Complete account restructure using Single Keyword Ad Groups (SKAGs) and tight exact/phrase match targeting
  • Built an exhaustive negative keyword list of 400+ terms, eliminating all irrelevant traffic immediately
  • Launched dedicated landing pages for each market and dumpster size category, dramatically improving Quality Score
  • Implemented call tracking with Google forwarding numbers and integrated offline conversions into Smart Bidding
  • Geo-targeted expansion strategy: dominated top markets first, then scaled to adjacent cities with proven cost models
  • A/B tested ad copy relentlessly — 3 rounds of testing over 6 months with statistically significant results

The 6-Month Transformation Roadmap

We didn't just tweak their campaigns — we rebuilt everything from the ground up, phase by phase, with clear milestones and measurable checkpoints.

M1
Month 1 — Audit & Foundation

Deep Account Audit + Immediate Waste Elimination

Conducted a full forensic audit of the existing Google Ads account. Identified $2,400/month in wasted spend from 3 sources: irrelevant keyword triggers, duplicate ad groups, and campaigns running in zero-demand markets. Paused all underperformers immediately and froze overspending.

AuditNegative KeywordsBudget Reallocation
M2
Month 2 — Rebuild & Restructure

Full Campaign Rebuild with Segmented Ad Groups

Rebuilt the entire account architecture using a tiered structure: Top cities → dumpster sizes → intent types (rent, pricing, near me). Created 18 tightly themed ad groups replacing the original 4 sprawling campaigns. Launched new keyword sets with exact and phrase match only — no broad match allowed.

SKAG StructureKeyword ResearchAd Copy
M3
Month 3 — CRO & Landing Pages

Market-Specific Landing Pages + Conversion Tracking

Launched 6 geo-specific landing pages, each tailored to the local market with city names, local reviews, and pricing context. Implemented call tracking via Google forwarding numbers and integrated phone conversions into the bidding algorithm. Quality Score jumped from an average of 4.2 to 7.8 across all ad groups.

M4
Month 4 — Bidding Strategy Shift

Smart Bidding Activation with Full Conversion Data

With 3 months of clean conversion data (including calls), we transitioned from manual CPC to Target CPA bidding. Set an aggressive initial target of $95 CPA (vs. the $185 baseline). Google's algorithm now had quality signals to optimize against — and costs began dropping week over week.

Target CPASmart BiddingtROAS
M5
Month 5 — Geo Expansion

Scaling Into New Markets with Proven Cost Models

With CPA under $90 in the core 3 markets, we used those markets as benchmarks to expand. Applied the same landing page formula, keyword structure, and bidding approach to 4 new metro areas. Initial CPA in new markets entered at $110 — and normalized to under $80 within 6 weeks.

M6
Month 6 — Optimization & Lock-In

Seasonal Adjustments + Long-Term Automation Setup

Built out dayparting schedules based on 6 months of hourly data — pausing ads during low-conversion overnight hours and increasing bids during peak booking windows (Tues–Fri, 8am–5pm). Finalized automated budget pacing rules and established monthly reporting dashboards for full transparency.

"We were spending nearly $7,000 a month and getting 18 bookings. Media Spearhead came in, rebuilt everything, and within 6 months we were getting 70 bookings on half the budget. I didn't think that was possible until I saw it happen."
