Law Firm PPC Management, Measured in Cost per Case

01

What Does a Law Firm PPC Agency Actually Do?

A law firm PPC agency builds, runs and measures your paid search campaigns so that ad spend turns into consultations and signed cases. Clicks are only the raw material. The work that moves results happens in places a monthly report rarely shows: the search terms report, the tracking setup, and what happens after the phone rings.

This is how CFS Marketing runs a law firm Google Ads account:

1. Tracking first. On an existing account, we define what counts as a conversion, test every form and call path, and compare Google Ads conversions with the leads in your CRM or intake log. Optimization waits until the two agree. On a new account, we build that tracking before the first ad runs.
2. Structure by practice area and intent. Each practice area gets its own campaigns, and urgent searches ("bankruptcy lawyer near me") are kept apart from research searches ("how does chapter 7 work"), so budgets follow case value.
3. Search terms and negative keywords, reviewed weekly during cleanup, then on a fixed schedule.
4. Ads and landing pages that match the search. We write them, and your firm approves every ad before it runs. Law firm ads are attorney advertising: the American Bar Association's Model Rule 7.1 bars false or misleading communications about a lawyer's services, and each state adopts its own version. Your firm decides what complies. We do not give legal or ethics advice.
5. Bidding to a target cost per case once tracking can be trusted, never to cheap clicks.
6. Reporting in your numbers. Leads, consultations, signed cases and cost per case.

What Results Has CFS Marketing Produced for a Law Firm?

CFS Marketing managed Google Ads for a bankruptcy law firm for four years, 2022 through 2025. The account delivered 1,511 total conversions, and its yearly cost per conversion fell every year. The firm came to us from another agency, so its 2021 numbers under that agency are the baseline.

Source: the firm's Google Ads account, full-year figures for 2021 to 2025, as reported in our case study. 2024 conversions were also verified against the firm's CRM.

What the table shows:

• CPA fell four years in a row. 2025 closed at $51.12, which is 16.8% below the 2021 baseline.
• Conversion rate peaked in the takeover year, then settled as volume grew. It hit 22.80% in 2022, then eased into the high teens. It never fell back to 13.43%. We read that as the normal cost of scaling: extra searches are a little less ready to hire.
• 2024 was the biggest year: 475 conversions, verified against the firm's CRM, not just Google's count.

A large part of the work was subtraction. Aggressive negative keyword management eliminated 40% of the low-intent traffic the account had been paying for.

These are one firm's results in one market. Your practice area, city and intake will produce different numbers, and we do not promise the same outcome. Client names are withheld on this site. The full bankruptcy engagement, including the intake side, is covered on our bankruptcy attorney marketing page.

How Much Should a Law Firm Pay per Case?

A law firm should pay no more per signed case than the case is worth after fees, costs and the margin the firm needs to keep. Cost per click is the wrong place to start. Whether law firm PPC works depends on your maximum cost per case, and you can work it out in three lines:

Worked example (hypothetical numbers, not a benchmark). A firm with a $3,000 average net fee that will spend 20% of it on acquisition can pay up to $600 per signed case. If one in four qualified leads signs, the ceiling is $150 per lead. A campaign running at $90 per lead has room to grow. One running at $220 per lead needs fixing, either in the account or at intake.

That math depends on two numbers that never appear in a Google Ads report: your average fee and your lead-to-case close rate. Bring both to the first call, or we set up tracking for them first.

04

How Does Law Firm PPC Differ by Practice Area?

Law firm PPC differs by practice area because case value, urgency and the kind of junk search each area attracts all differ. One playbook run across personal injury and estate planning wastes money in both.

Each row changes the budget split, the ad schedule and the negative keyword lists. We build criminal defense ad schedules around late-night calls, which means someone has to answer at 11 p.m. Estate planning schedules rarely need that.

05

Should a Law Firm Run Local Services Ads or Google Search Ads?

Most law firms with a real budget should run Google Search Ads as the core and test Local Services Ads alongside them, because the two buy different things. Local Services Ads charge per lead, not per click, and you can dispute leads you believe are invalid. Search Ads charge per click but give you control over keywords, ad copy, landing pages and negative keywords.

We log LSA leads in the same intake sheet as Search leads, so you can compare cost per signed case between the two channels directly.

06

Why Do Law Firm PPC Campaigns Attract Bad Leads?

Law firm PPC campaigns attract bad leads when loose keyword matching, wide location settings and missing negative keywords let Google spend your budget on searches that were never going to hire a lawyer. The fix lives in the search terms report, not in the ad copy.

What we check first:

• The search terms report: the searches that actually triggered your ads, read line by line.
• Negative keywords. Typical blocks include "jobs", "salary", "paralegal", "law school", "forms" and "DIY", plus a list for each practice area. "Free" needs care: "free consultation" searches can be good leads for a firm that offers one. On the bankruptcy account above, this work removed 40% of the low-intent traffic.
• Location setting. Google Ads defaults to "Presence or interest", which can show your ads to people outside your area who are only interested in it. A firm licensed in one state usually wants "Presence" instead.
• Call conversion length. Google Ads counts a call as a conversion once it passes a minimum call length you set. If that setting is too short, wrong numbers and sales calls get counted as leads.
• Match types. Broad match only after conversion data is trustworthy and a target cost per case is set.

07

Why Do Call Tracking and Intake Decide Law Firm PPC Results?

Call tracking and intake decide law firm PPC results because Google Ads can only optimize toward the conversions you report to it, and a law firm's real conversion, the signed case, happens on the phone and in intake, outside Google's view. If a campaign is tuned to form fills and 30-second calls, you get more form fills and 30-second calls.

What closes that gap:

1. Call tracking numbers on the site and in the ads, so each call ties back to its campaign and keyword.
2. Call outcomes logged by intake: qualified, not qualified, consultation booked, signed.
3. Offline conversion import, which sends signed cases back into Google Ads so bidding learns which searches become clients. Google only accepts imports within 90 days of the click, so the upload has to be routine.
4. A missed-call review of after-hours and weekend calls. An unanswered call wastes the click.

Bad tracking hides well. In a tracking audit for an education client (not a law firm), we cross-referenced 1,462 reported conversions against the client's form database and found zero matches. Any bidding decision based on those numbers was based on leads that did not exist. Our GA4 conversion tracking service fixes this before a dollar of optimization is spent.

08

How Do You Audit Your Current Law Firm PPC Agency?

You audit a law firm PPC agency by checking two things: whether its numbers tie back to signed cases, and whether your firm controls the account and the data. Ask these ten questions:

1. Is the Google Ads account in your firm's name, with someone at the firm as an admin?
2. Can the agency show cost per signed case, not just cost per conversion?
3. What exactly counts as a conversion? Page views, phone-number clicks and very short calls inflate the count.
4. Do the conversions in Google Ads roughly match the leads in your intake log for the same month?
5. When was the search terms report last reviewed, and which negatives were added?
6. Does each practice area have its own campaigns and budget?
7. Is location targeting set to "Presence" or to "Presence or interest"?
8. Is call tracking in place, and do signed cases get imported back into Google Ads?
9. Does your firm approve ad copy before it runs?
10. Did last month's report lead to a change, or did it only describe last month?

Three or more answers of "no" or "I don't know" mean the account deserves a second look. For audits outside legal, see our Google Ads consultant service.

What Does Law Firm PPC Management Cost with CFS Marketing?

CFS Marketing's law firm PPC management runs on a monthly retainer, scoped by how many practice areas, campaigns and tracking fixes the account needs. Cesar quotes after reviewing your accounts. Ad spend is separate from the retainer. We are the right fit for firms spending $3,000 or more a month on Google Ads, or ready to, whether we're rebuilding an existing account or setting up a new one.

We don't guarantee leads, cases or rankings: Google runs the auction, and your intake team decides the close. We commit to a clean account, tracking you can trust, and reports in cost per case.
