62% Lower CPA and 3.2x Signed Cases Through Google Ads Optimization
How restructuring a $85K/month Google Ads account, building conversion-optimized landing pages, and implementing call tracking transformed paid search into a predictable case pipeline.
The Challenge: $850 Per Lead in the Most Expensive PPC Vertical
Legal PPC is the most expensive Google Ads vertical in existence, with personal injury keywords reaching $150-$400+ per click. Our client — a mid-sized personal injury firm — was spending $85K/month but generating only about 100 leads at an $850 CPA. Worse, only 18% of those leads converted to signed cases, meaning each signed case cost over $4,700 in ad spend alone.
The account had classic mismanagement symptoms: broad match keywords bleeding budget to irrelevant queries, a single landing page for all campaign types, no call tracking, and no bid strategy beyond "maximize clicks" — the worst possible strategy in a $200+ CPC environment.
The Strategy: Precision + Conversion + Tracking
Account Restructure
Rebuilt the account from scratch: single keyword ad groups (SKAGs) for top-converting terms, phrase/exact match only (eliminated all broad match), and aggressive negative keyword lists built from 18 months of search query data.
Landing Page Per Practice Area
Created 8 dedicated landing pages — one for each practice area (car accident, truck accident, slip & fall, etc.) — with social proof, case results, and click-to-call CTAs above the fold. Average conversion rate jumped from 4.8% to 14.2%.
Call Tracking & Attribution
Implemented dynamic number insertion and call recording across all landing pages and GBP. Integrated CallRail with Google Ads for automated conversion tracking — finally giving the algorithm real conversion data to optimize against.
Bid Strategy Overhaul
Migrated from Maximize Clicks to Target CPA with offline conversion import (signed cases fed back to Google Ads). The algorithm learned to bid higher for queries that produce signed cases, not just clicks or form fills.
