PPC for Lawyers: What Google Ads Cost per Signed Case

PPC for lawyers (pay-per-click ads such as Google Ads) earns its keep when the cases it signs bring in more than the clicks and the management fee cost. Your practice area sets the difficulty: Google Ads Keyword Planner estimates put the average US estate planning click at a few dollars and a truck accident click in the hundreds. Before spending, work out how many signed cases a month the budget has to bring, then count them in your case management system rather than the ad report.

Quick answer

1. Look up your practice area in the click-price table below.
2. Add any agency fee to the month's ad spend and divide by the average fee one signed case brings in. The result is how many signed cases a month you need to break even.
3. Ask whoever runs the ads about the location option, the negative keywords, the ad schedule and which calls are counted as conversions.
4. Find out whether Google is recording calls from your ads. Recording is now the default.
5. Tag every new contact in your case management system with a source, and judge the ads by signed cases once three months have finished.

What do clicks cost in your practice area?

CPC, cost per click, is what you pay each time someone clicks. The averages below are US-wide estimates from Google Ads Keyword Planner, October 2026, so your firm's own click prices will be different.

I worked out the last column myself as $3,000 ÷ average CPC, rounded. What it can't tell you is how many clicks your firm needs to sign one case. What a signed personal injury case costs takes the top rows further.

How many signed cases does the budget need?

• Break-even signed cases = (ad spend + agency fee) ÷ average fee per signed case
• Break-even click price (before any agency fee) = average fee per signed case × contact rate × sign rate

Contact rate means new contacts ÷ clicks; sign rate means signed engagement agreements ÷ contacts. For the average fee, use your flat fee, the hours you expect to bill, or on contingency work your own estimate of what a typical case pays.

Illustrative: the firm below is imaginary, a two-lawyer estate planning practice, and I invented every figure in its month; no client's numbers are in it.

An agency report would show cost per conversion, $3,000 ÷ 38 = $78.95. The firm cares about cost per signed case, ($3,000 + $750) ÷ 4 = $937.50. Break-even is $3,750 ÷ $2,400 = 1.56 signed cases, so two would have covered the month, and the four it signed brought in $9,600 in fees.

Its break-even click price works out to $2,400 × (30 ÷ 400) × (4 ÷ 30) = $24.00, and it paid $7.50 a click ($3,000 ÷ 400). Clicks per signed case, here 400 ÷ 4 = 100, is the figure to compare across practice areas. If truck accident searches also needed 100 clicks per signed case, the planner's average would put one case at $509.15 × 100 = $50,915 in clicks.

File each contact under the month it first reached you and revisit row 8 a month on, since some people sign weeks later. Google Ads does the same, reporting a conversion on the day of the click behind it (Google, checked 2026-10-04).

Which settings decide who sees your ads?

Any search containing a negative keyword won't show your ad. Blocking "free" also blocks "free consultation", so only add it if you don't offer one. Presence or interest can fit a child out of state handling a parent's estate in yours, but it should be a deliberate choice. If nobody picks up at night, the call asset (the phone number shown with the ad) can be set to appear only while the firm answers (Google, checked 2026-10-04).

Which calls count, and is Google recording them?

Whatever the account counts as a result is a conversion, and automated bidding goes looking for more of the same. With call reporting on, the ad displays a Google forwarding number that passes calls straight to your own phone, and Google notes when each one started, how long it lasted and whether it got through (Google, checked 2026-10-04). When a call isn't recorded, "Calls from ads" counts it if it runs past a set length, which is 60 seconds unless someone changed it (Google, checked 2026-10-04). A current client phoning about their file can pass 60 seconds too, so time a few genuine intake calls and ask which length the account uses. How forwarding numbers count calls has the setup.

Google says its recording setting "is now enabled by default to allow for AI-powered lead qualification". The exceptions are accounts where someone switched it off earlier and businesses Google identified as healthcare or financial services. People calling get a short spoken notice, and the feature covers US and Canadian numbers only (Google, checked 2026-10-04). Once it's on, Google's AI assesses every recorded call for signals, a caller booking a consultation for instance, and counts only the calls it judges qualified; the set length then matters only for calls it can't record (Google, checked 2026-10-04). You'll find the switch under Admin, Account settings, Call ads, Call recording.

ABA Model Rule 1.18 treats a person who consults a lawyer about possibly hiring them as a prospective client. Even when no engagement follows, the lawyer may not use or reveal what that person said, beyond the limited uses the rules allow for a former client's information (ABA, checked 2026-10-04). Whether recordings Google keeps and analyzes square with that duty, and with your state's law on recording calls, is for your state bar's rules and ethics guidance to settle. I'm not a lawyer, and none of this is legal advice; someone at the firm should make this decision, not the default.

Why does intake decide the result?

The ads have done their job once the phone rings. After that it's intake: picking up, the conflict check, qualifying, booking the consultation, the engagement agreement. In the invented month, twice the sign rate would have turned the same 400 clicks into eight signed cases with no extra ad spend.

So the counting happens in the case management system, by source: new contacts, qualified, consultations held, signed, fees. The source comes from a phone number reserved for the ads, a landing page no other channel uses, and intake asking every caller how they heard about the firm. Law firm intake, step by step shows how to count each stage by source, and why Google's lead count runs higher than yours.

What do the bar's advertising rules say about the ads?

Your state bar writes the rules that bind you; I cite the ABA's national model. Rule 7.1 says "A lawyer shall not make a false or misleading communication about the lawyer or the lawyer's services" (ABA, checked 2026-10-04). Paying the reasonable costs of advertisements is allowed by Rule 7.2, which also forbids stating or implying that a lawyer is certified as a specialist unless the certifying organization was approved by a state authority or accredited by the ABA and the ad names it. And every ad must name at least one lawyer or firm that is responsible for its content, with contact details for them (ABA, checked 2026-10-04).

The ABA's comment on that rule generally lets a lawyer use "specialist" on the strength of experience, provided the claim holds up under Rule 7.1 (ABA, checked 2026-10-04). So any search ad headline with "certified" or "specialist" in it needs checking against your state's version. Ask, too, who at the firm approves ad text and landing pages. Read your own state's rules; this is not legal advice.

What should the first 90 days show?

• Month one: a test call placed from the ad shows up in call details, a test form arrives, you know whether calls are counted by length or by Google's AI, the settings above have been decided, and each new contact carries a source.
• Month two: someone can explain why conversions and contacts differ, and contacts from the ads are booking consultations.
• Month three: the signed cases from the first two months are measured against their break-even.

When the numbers fall short, the funnel tells you where to look. Few contacts per click points to the ads, the settings or the landing page; contacts who don't qualify, to search terms and location; qualified people who never sign, to intake. Once signed cases are being counted, they can be sent back into Google so bidding chases signed cases rather than calls; offline conversion tracking from your CRM covers that step.

The monthly report from whoever runs the account should give you:

• Spend, clicks and average CPC for each campaign
• The top search terms, and which negatives were added
• Each action in the Conversions column, and whether calls are counted by length or by Google's AI
• The current location option, ad schedule and call recording setting, plus any change
• Cost per signed case from your case management count, side by side with cost per conversion
