How to Run Google Ads for Lawyers (Full Guide)

Somewhere right now, someone who was just in a car accident is lying in a hospital bed, phone in hand, searching for a personal injury lawyer before they've even been discharged. Somewhere else, someone who's been putting off a divorce for a year finally searched "divorce attorney near me" at midnight because tonight was the night they decided they were done waiting. Both of those searches are worth real money to a law firm, but not the same amount of money, not even close, and that difference is the entire strategy this guide is built around.

(Legal ads have a reputation for being expensive. They are. What most guides skip is that "expensive" only matters relative to what a won case is actually worth, and that's a number most firms never actually calculate before setting a budget.)

This guide walks through the whole process in order: setting a real budget, researching keywords, building ad groups around case type and urgency, writing what the ad says, building landing pages, nurturing the lead, reporting on real case value instead of raw lead count, and the routine maintenance that keeps an account from quietly rotting. Most guides on this topic compare cost-per-click across practice areas and stop there. This one covers what a lead is actually worth once it becomes a client, because for a law firm, that's the number that should be driving every other decision.

Step 1: Set Your Budget Around Your Highest-Value Case Type

Before you touch a keyword, decide what you're actually advertising first.

Law firms usually handle a mix of case types, and they are never worth the same amount. A single serious personal injury case or a contested divorce can be worth more to a firm than a hundred simple consultations combined. Pick the practice area with the best return per case first, and budget around that, not around whichever keyword happens to be cheapest. A $200 click that turns into a $40,000 case is a better use of budget than a $20 click that turns into a $500 retainer, even though the second one looks cheaper on a spreadsheet that only tracks cost per click.

Plan for a minimum of $1,000 a month to start, but go in expecting to spend more for competitive practice areas. Cost per click for legal keywords commonly runs $50 to $200 or more for terms like "personal injury lawyer" or "criminal defense attorney" in a competitive metro. At $1,000 a month and a $75 average click, that's roughly 13 clicks to start, which sounds small, but for a case type worth tens of thousands of dollars, even a low click count can be worth every dollar spent. That range shifts enormously by practice area and market... you get the point. Less than $1,000 a month and you won't collect enough data to know what's actually working.

Step 2: Do Real Keyword Research

Guessing at keywords is how legal budgets disappear fastest, since the clicks are the most expensive in almost any industry. Use Google's Keyword Planner inside your Ads account to see real search volume and cost estimates for legal terms in your practice area and location, or use a paid tool like Semrush's Keyword Magic Tool or Ahrefs' Keywords Explorer if you want more data layered on top.

Look for practice-area-plus-location terms that show real hiring intent: "car accident lawyer [city]," "divorce attorney free consultation [city]," "DUI defense lawyer near me." Skip broad terms like "lawyer" or "attorney" on their own. They pull in job seekers and people researching law school as easily as people who actually need to hire someone, and legal clicks are too expensive to waste on either.

Inside Keyword Planner, click the checkbox next to every keyword with decent volume that shows real hiring intent, tagging each one mentally by practice area and urgency as you go, since that split matters in the next step. Once you've got a solid list, at least 30 keywords is a good minimum, click "Download keyword ideas" in the top right and export it as a spreadsheet. Sort that list by practice area. That sorted list becomes the skeleton for the ad groups in the next step.

Step 3: Build Ad Groups Around Practice Area and Case Urgency

This is where most legal accounts quietly lose money, and given the cost per click, "quietly" doesn't stay quiet for long. One campaign covering every practice area shows someone searching right after a car accident and someone researching a will they'll get to eventually the exact same ad.

Split your ad groups by practice area first, then by urgency within each:

High-urgency, high-value intent — "car accident lawyer," "DUI defense attorney." The searcher often needs to act within days, and the case value is usually significant.
Considered, high-value intent — "divorce attorney," "business litigation lawyer." The searcher is comparing firms over a longer timeline, but the case is still worth real money.
Lower-value, transactional intent — "will and estate planning," "simple LLC formation." The searcher wants a straightforward service at a predictable price, useful for volume but not where your biggest budget should go.

We took over a Cincinnati landscaping account with the exact same underlying problem, one campaign trying to cover every kind of search with one generic ad. After splitting ad groups to tightly match search intent instead of running one ad for everything, the primary ad group's click-through rate reached 15 percent, three to five times the industry average. Legal accounts see the same lift for the same reason, and at $100-plus a click, a higher click-through rate on the right ad group matters even more than it does in almost any other industry.

Step 4: Write Ads That Match the Search, Word for Word

Marketers call this "ad copy." It just means the actual words on your ad, the headline and the description underneath it. Write those words to mirror the exact terms in that ad group's keywords, not a generic pitch that could belong to any firm.

Someone searching "car accident lawyer free consultation" wants to see "Car Accident Lawyer — Free Consultation" in your headline, not "Experienced Attorneys You Can Trust." Specific beats broad every time on a search results page, because specific tells the searcher you handle their exact situation.

A real detail does real work here too. "No Fee Unless We Win" answers the single biggest hesitation someone has before they even click, whether hiring a lawyer is something they can afford right now. If that's how your firm actually works, say it in the ad itself, not just on the landing page three clicks later.

Step 5: Build a Landing Page for That Exact Ad Group

Every ad group needs its own landing page, built around the exact practice area that group is advertising, with content that builds trust with someone who's about to hand a stranger one of the most stressful situations in their life.

The words on the page should match the words in the ad as closely as the ad matched the keyword. Every paid click has to land on a dedicated page for that exact practice area, never the firm's generic homepage. A homepage that lists every practice area the firm handles is genuinely useful to nobody who clicked an ad for one specific kind of case. A dedicated, focused landing page converts at 15% to 20% or higher. A generic homepage, even a good one, converts visitors at roughly 2% to 3%. Sending a $150 personal injury click to a homepage listing twelve unrelated practice areas is one of the most common, and most expensive, mistakes we see when we audit an account someone else built.

For legal specifically, the trust content matters as much as the practice description: real case results (where your bar allows disclosing them), a clear statement of fees or contingency terms, and a simple, low-friction way to request a free consultation without a long intake form standing in the way.

Step 6: Set Up Lead Nurture So a Real Case Doesn't Slip Through

This step is optional, but it's the one that decides whether the rest of this guide actually pays off, especially given how much each click costs.

Every lead needs to be tracked back to where it came from, when your office contacted them, and what happened next. Without that, you're flying blind on which practice areas and keywords are actually producing signed clients, not just cheap inquiries. On top of tracking, set up automated follow-up for the moments your intake team is unavailable, because someone calling three law firms after an accident is going to hire whichever one calls them back first.

We audited a contractor's account with the same underlying problem, real traffic and real clicks, but losing money anyway. The issue wasn't the ads, it was follow-up: leads were falling through the cracks because nobody responded fast enough, and by the time someone did, the prospect had already hired the next name on their list. Once automated missed-call text-backs and simple pipeline tracking went in, every dollar of ad spend could finally be traced to a real signed case instead of disappearing into a black hole between the click and the callback. A lead followed up with in the first five minutes is 400% more likely to convert. For a $150 click on a case worth tens of thousands of dollars, that response-time gap is the most expensive five minutes in the whole campaign.

That's what our lead management systems are built to catch.

Step 7: Track Reporting Back to Real Case Value

Impressions and clicks don't cover a paralegal's payroll. The only numbers that actually matter are cost per signed case and closed revenue, weighted by what each case type is actually worth, not a flat cost-per-lead number that treats a $500 consultation and a $50,000 case as identical.

Track both levels every month:

Total Ad Spend ÷ Signed Cases From Ads = Cost Per Signed Case
(Value of Cases Signed From Ads) − Total Ad Spend = Total Profit From Those Cases

Run the first line to sanity-check your cost per click and cost per lead within a practice area. Run the second line off the actual value of the cases that came in, not an average across every practice area you handle, since averaging a $500 case with a $50,000 case tells you almost nothing useful. A campaign that looks expensive off cost-per-lead alone can be deeply profitable once the real case value runs through the math, which is exactly why judging a legal campaign off lead count instead of case value undersells it, sometimes by an enormous margin.

Step 8: Reupload Your Best Clients Into Google Ads

Once a campaign has produced some real signed cases, take the list of clients from your highest-value practice area, the case type that actually pays your firm's bills, and upload it back into Google Ads as a Customer Match audience. That tells Google's system, in plain terms: find me more people like these ones.

This matters more for a law firm than for almost any other business, because "more people like this" means more high-value cases, not just more inquiries. Uploading every lead who ever filled out a form, including the ones who never became clients or only ever needed a low-value service, muddies the signal. Keep the list built around who actually became a real, valuable case.

Step 9: Do Routine Maintenance Every Week

A Google Ads account left alone drifts, and at legal cost-per-click rates, drift gets expensive fast. Keywords that never converted keep burning budget, and searches you never wanted to show up for start triggering your ads anyway.

Set a recurring reminder on your phone or block time on your calendar, and split the routine across a few specific days instead of trying to do it all in one sitting:

Monday — Review which keywords spent money last week without producing a real inquiry.
Wednesday — Add negative keywords for irrelevant searches, like "law school," "paralegal jobs," or "free legal advice" if you don't offer it.
Friday — Adjust bids on keywords that are converting well but could use more visibility, especially within your highest-value practice area.
Any day something is obviously dead weight — Pause it. Don't wait for the scheduled day to pull the plug on a keyword that isn't working.

This single habit, cleaning up wasted keywords and adding negative keywords, typically eliminates 20% to 40% of wasted ad spend in the first month alone. At $50 to $200 a click, that percentage translates into real dollars fast. Skip it and the waste doesn't show up all at once, it adds up quietly until a real chunk of an expensive budget is gone with nothing to show for it.

Step 10: Check What Your Competitors Are Running (Later, Not First)

This isn't a priority when you're just getting started, but it's worth knowing once your own account is stable. Google's own Ads Transparency Center lets you search any competing firm's name and see every ad they're currently running, for free.

It's a useful gut check every few months on whether your own ads still stand out in a crowded, expensive market. We've written a full walkthrough on exactly how to use it, including what it can and can't tell you, in our guide to checking a competitor's Google search ads.

A Basic DIY Setup Guide

If you want to try setting this up yourself before deciding whether to hand it off, here's the short version:

Create a Google Ads account at ads.google.com using your firm's business email.
Click Tools in the left-hand menu, then Keyword Planner under the Planning section, and pull search volume for the practice area you picked in Step 1.
Click Campaigns in the left-hand menu, then the blue + button and choose "New campaign." Pick "Leads" as your goal, and build the campaign around that one practice area, with location targeting set to where you actually take cases.
Inside that campaign, click Ad groups, then add a new one for a single search intent from Step 3. Add your keywords to it, then click into the ad itself and write the headline and description to match those keywords directly.
Before you turn the campaign on, go to Goals, then Conversions, in the left-hand menu and set up basic conversion tracking for calls and form submissions. This step matters more here than almost anywhere else, since untracked clicks at legal CPCs are simply money you can't account for.
Check performance after the first week, and again every week after that.

That's enough to get a real campaign live and collecting data. It is not the same as running one at scale, especially once you're managing separate campaigns across multiple practice areas with very different case values.

When This Gets Too Big to Run Yourself

Setting up one campaign for one practice area is something a lot of firm owners can do on a weekend. Running several campaigns well, each with its own ad groups, landing pages, lead nurture, and weekly maintenance, at $50 to $200 a click, is close to a full-time job where mistakes are expensive. There's nothing in this guide that requires an agency if you've got the time to learn it.

Where it usually breaks down is bandwidth, not knowledge. Somewhere between handling cases and running a firm, "check the ads account" quietly stops happening every week, and at legal CPCs, that's exactly when real money starts leaking out. If that's where you're at, an audit is the fastest way to find out whether an existing account is actually working, and our Google Ads management service picks up everything from Step 1 through Step 9 above, plus the growth side: knowing when to add a new practice area, expand your service area, or push more budget into your highest-value case type. Anyone can turn a campaign on. Scaling one without burning an expensive budget is the part that takes an actual growth partner.

Turn This Into Signed Cases, Not Just Clicks

Every step in this guide points at the same outcome: a click that turns into a call, a call that turns into a real inquiry, and an inquiry that gets tracked well enough to show what it was actually worth once it became a case, not just what it cost to get the click.

Start with the budget and the keyword research if you're doing this yourself this week. If you'd rather have someone build the whole system, including the landing pages, lead nurture, and case-value reporting, schedule a strategy call and we'll walk through what your account could look like with all nine steps actually in place.
