PPC for Law Firms

A managing partner sees 40 calls last month and assumes the campaign is working. But 15 were people looking for free legal aid. Eight were the wrong practice area. Five were out of jurisdiction. The agency reports "40 leads generated" and bills accordingly. Nobody asks how many of those calls became retained clients.

This happens because most PPC management for law firms optimizes for the wrong metric. Cost per click. Cost per call. Cost per form fill. None of those tell you whether the campaign is producing revenue. A $50 click that becomes a probate case worth $8,000 is a fundamentally different outcome than a $50 click from someone Googling "how to write a will myself." Most agencies can't distinguish between the two, and they don't try.

The other common failure: running every practice area through one campaign with one landing page. Probate, family law, personal injury, and criminal defense have different CPCs, different case values, and different client intent. Treating them as one campaign means the algorithm optimizes for whatever generates the cheapest clicks — not the most valuable cases.

How We Run PPC for Law Firms

We structure law firm PPC the way a firm structures its practice — by practice area, with each area treated as its own unit with its own economics.

‍Practice area segmentation. Each practice area gets its own campaign, budget, keyword set, and landing page. A $50 click for a probate case is a different bet than a $300 click for personal injury. The campaign structure reflects that so you can allocate budget toward the areas where case value justifies acquisition cost.

‍Negative keyword discipline. Legal search is full of queries that look relevant but aren't — "free legal advice," "how to represent myself," "legal aid near me," "pro bono lawyer." Without systematic negative keyword management, these eat budget fast. We build comprehensive lists from day one and expand them continuously from actual search term data.

‍Dedicated landing pages per practice area. Not the firm homepage. Not a generic services page. Someone searching for a probate attorney lands on a page about probate — with relevant credentials, case types handled, and a clear path to schedule a consultation.

‍Call tracking and lead quality scoring. Every phone call from a PPC campaign is recorded, attributed to a specific keyword, and scored on whether it was a qualified intake. Monitoring call duration and disposition closes the loop between ad spend and cases the firm actually takes. This is where most agencies stop short — and it's where the real optimization happens.

‍Budget allocation by practice area ROI. Once we have qualified intake data by practice area, we shift spend toward the campaigns with the best ratio of case value to acquisition cost. This is how pay per click for law firms scales profitably — by concentrating budget where the unit economics work, not spending more across the board.

As a B2B Google Ads agency, we apply this same pipeline-focused approach across every vertical we manage. For law firms, the difference is that "pipeline" means retained cases — and every decision we make ladders up to that number.

Cost Per Qualified Lead: $300 → $82

We took over a probate law firm's Google Ads account that appeared to be generating 8 conversions per month on roughly $600 in ad spend. The numbers looked fine on the surface. The reality: nearly every lead was spam.

The account had Search Partners and Display Network enabled — which, for legal lead gen, almost always drives junk traffic. Sixty-nine of 79 enabled keywords had never produced a single conversion. Legacy ad formats were still running. No call tracking, so the firm had zero visibility into whether phone calls from ads were actual prospective clients or noise.

We stripped it down and rebuilt. Excluded Search Partners and Display. Paused the 69 non-converting keywords and shifted to exact match on the highest-intent terms. Built a negative keyword list of 113 terms covering free legal services, informational queries, and out-of-jurisdiction searches. Rebuilt ads as Responsive Search Ads with messaging aligned to the landing page. Implemented call tracking through CallTrackingMetrics so we could verify which calls were genuine inquiries versus junk.

The initial honest number was ugly: cost per qualified lead spiked to $300. That's because we were now only counting real leads — qualified intakes from people who actually needed a probate attorney. The spam was gone, and the true cost was exposed.

Through persistent optimization — refining keywords, tightening targeting, testing ad copy with headline pinning — cost per qualified lead dropped to $82. Over 90% of leads were cases the firm actually wanted to take. The firm scaled monthly spend from $600 to $1,500 with confidence that every dollar was producing real business.

We didn't just make leads cheaper. We made sure the leads coming in were cases worth taking. That's what PPC for lawyers should look like — cheaper and better at the same time.
