How Much Does a Lead Cost for a Law Firm? $7.50 to $11

How much does a lead cost for a law firm? In our campaign an inquiry from a prospective client cost from about $7.50 at the start to $11.35 at full scale, at about 99 valuable inquiries a month. It is the most expensive industry in our benchmark of 20 campaigns across 11 industries, but also the one where a single new client can pay back a whole month of ad spend. The numbers come from a real campaign in Europe, converted to US dollars, described in our law firm case study.

How much did a lead cost in our law firm campaign?

The campaign ran for a law firm serving mainly one large metro area, with a starting budget of $750 a month. A lead was an inquiry through a callback widget (a “call me back” button), a contact form or a click on the phone number; we tracked all three events in Google Analytics 4.

At the start, the cost per inquiry was about $7.50. As we raised spend in Google and on Facebook in cycles, the cost settled at $11.35, and the firm was receiving about 99 valuable inquiries a month. The front desk screened every inquiry before passing it to the owner, so we are talking about inquiries after a first round of vetting, not raw clicks.

Why does a lead for a lawyer cost more than in other industries?

Two reasons show up directly in the data. First, competitors bid on the same keywords: someone searching “divorce attorney near me” is worth a lot to every firm in the city, so clicks in Google Search are among the most expensive on the market. Second, the value of a case is high, so firms can afford an expensive inquiry and push bids up.

For comparison, in our benchmark a dental lead cost about $2, a beauty salon lead $2 to $3.50, and a medical aesthetics lead $5 to $7. Legal services close out the list, but the math has to be done on client value: with cases worth thousands of dollars, an $11 inquiry is still a cheap sales channel. In the US market, where legal keywords are among the most expensive in Google Ads, expect the absolute numbers to be higher; the ratios between industries are what carries over.

How do you split a law firm’s ad budget across channels?

In the campaign described here the split was: 70% Google Search Ads, 25% Facebook and Instagram Ads, 5% Google Display. The ratio follows intent: most valuable inquiries come from people actively searching for legal help, so Search gets most of the money. Social media works mainly on retargeting and recognition, and Display closes the funnel with a cheap reminder.

Before the campaign launches, the site has to be ready for it: a clickable phone number, working GA4 tracking, and pages for specific practice areas. At the start, Google had indexed only 4 pages of this client’s site, which had to be fixed before scaling. Campaigns like this are run by our Google Ads agency team, and we write more about when to bet on search and when on social media in our comparison Google Ads vs Facebook Ads.

When is a rising cost per lead fine?

When it rises together with volume and the business can handle it. In this campaign the cost per inquiry rose from about $7.50 to $11.35, but the number of valuable inquiries reached a level where the firm could barely keep up and started looking for a salesperson and writing sales procedures. That is a good problem: advertising stopped being the bottleneck, and the firm’s capacity became one.

The warning sign would be a rising cost without a rise in the number or quality of inquiries. That is why, alongside CPL, it is worth tracking how many inquiries pass front desk screening and how many end in a signed engagement.
