Chapter 5 ended with a short, clean list: the hiring searches a firm can name, sorted by case type, with the rival names and free-help searches stripped out. That list is the firm's best guess at how its clients search.
Clients don't read the list. A woman whose rideshare driver ran a red light doesn't type "car accident lawyer." She types "uber accident lawyer," or "lawyer for passenger injured in lyft," or something stranger, half a sentence long, at two in the morning with a sore neck. A man bitten by his neighbor's dog doesn't type "personal injury attorney." He types "dog bite lawyer near me."
A good Google Ads account covers both: the searches a firm can name in advance, and the ones it never would. This chapter shows how, in the order that keeps the budget safe.
A Firm Can Write Down "Truck Accident Lawyer." It Can't Write Down What a Crash Victim Types at 2 a.m.
We build accounts inside out. The center is the searches a firm knows convert. The outer ring is everything else people type when they need that kind of lawyer, which is wider and harder to predict.
The middle of that picture belongs to Isolation, our label for an exact match campaign whose bids a human sets one ad group at a time. Google describes exact match as reaching searches that carry the same meaning as the keyword, and when someone types the keyword word for word, that exact keyword gets first claim on the search. It's precise. It's also narrow by design. An Isolation campaign built on "truck accident lawyer" won't wander off to "trucking company lawsuit settlement time."
The outer ring belongs to what we call an Exploration campaign: broad match with a target cost per qualified consultation, so Google's bidding decides how much each search is worth. In Google's telling, broad match reaches searches merely related to the keyword, including some that never use its words or its literal meaning. That's how it finds searches nobody would list. Google also calls Smart Bidding "critical" with broad match, because each of those odd searches deserves its own price, and no firm can set thousands of bids by hand.
What about phrase match, the setting between the two? We leave it out of this structure. Exact match gives a new account control while it gathers data, and broad match with Smart Bidding gives reach once that data exists. Phrase match offers a little of each and not enough of either, and running it alongside the other two muddies the question each campaign is supposed to answer: what did the searches we know produce, and what did the searches we didn't know produce?
"Car Accident Lawyer" Has Cousins. Uber, Hit-and-Run and Crosswalk Searches Each Draw Thousands.
Start with the cousins you can see. Keyword Planner shows these US monthly searches for injury cases that a list built around "car accident lawyer" would miss:
- "Dog bite lawyer": 14,800
- "Pedestrian accident lawyer": 12,100
- "Hit and run lawyer": 9,900
- "Bicycle accident lawyer near me": 8,100
- "Uber accident lawyer": 6,600
- "Rideshare accident lawyer": 5,400
- "Construction accident lawyer": 4,400
- "Bus accident lawyer": 4,400
- "Lyft accident attorney": 3,600
Each one is a different case. A rideshare crash involves the rideshare company's insurance. A hit-and-run often turns on the client's own uninsured motorist coverage. A pedestrian case has its own facts and its own value. If your firm takes these cases, the big cousins deserve their own exact match ad groups and their own pages, built the way Chapter 4 described. Add them as you find them.
A rideshare ad group, for example, might hold "uber accident lawyer," "lyft accident attorney," "rideshare accident lawyer" and "uber accident lawyer near me," with headlines that say "Rideshare Crash Lawyer" and a page that explains how the rideshare company's coverage works. The person who typed "uber" sees "uber" or "rideshare" back, which is the ad relevance Chapter 4 is built on.
Every practice area has cousins like these. A DUI firm's main searches have relatives for underage charges, commercial drivers and second offenses. A family firm's "divorce lawyer" has relatives for custody, grandparents' rights and support changes. Look for them in Keyword Planner first, then in the search terms once broad match is running.
Then there's the part you can't see. Below the searches Keyword Planner lists sits a tail of phrasings too rare for it to report: the half-sentence searches, the specific intersections, the questions typed in a panic. Google even leaves the rarest of them out of the search terms report to protect privacy. A firm can't build exact match keywords for searches it will never see in a list.
We'll be honest about the numbers. In Keyword Planner's own export for these injury searches, most of the volume sits in the big searches, not the small ones. That export can only show what Planner counts. The case for broad match isn't that the tail is bigger on paper. It's that the tail exists, that no one can list it, and that only broad match with Smart Bidding can reach it at a sensible price.
Exploration Waits for About 30 Quality Leads a Month. Busy Firms Get There Sooner.
Broad match is powerful and expensive in the wrong hands. Turn it on too early and Google spends the budget learning on searches it can't yet judge, because the account hasn't shown it what a good lead looks like.
So Exploration waits for a signal: about 30 quality conversions a month, the qualified consultations Chapter 1 set up as the bidding goal. For most firms that's the usual pace of two to three months after launch. An injury firm spending heavily might cross it within weeks. A solo estate practice may take longer. The calendar is only an example. The volume is the gate.
When the gate opens, Exploration launches like this:
- A copy of the Isolation campaign, same structure, same pages.
- Seeded with a few proven winners, three to five keywords with qualified consultations behind them, never the full list.
- Broad match only.
- Maximize conversions with a target cost per acquisition, which Google relabeled "Target CPA" in June 2026. Set it from what Isolation actually paid for each qualified consultation; a wished-for number trains the algorithm on fantasy. Google suggests judging a target over at least 30 conversions, the same number as the gate.
- The negative list from Chapter 5, loaded before day one.
Then give it one to two months. Smart Bidding needs that long to learn which searches turn into consultations for your firm.
Two details keep it from going wrong. First, only a handful of seed keywords, because broad match already stretches each one far beyond its words; twenty seeds would send the campaign in twenty directions before it learns any of them. Second, Exploration gets its own budget. If it shares a budget with Isolation, a busy week of broad match can quietly starve the exact match searches that were already producing cases.
The First 30 Days of Exploration Are a Morning Habit, Not a Setting.
For the first month, the search terms report gets read every day. It's the list of what people actually typed before your ad appeared, and in the first weeks of broad match it's full of surprises.
Most of the surprises fall into a few piles:
- Rival firms and individual lawyers by name. Block them, plus their misspellings, since negatives don't stretch to close variants.
- Directories, free clinics and job hunters, the same groups Chapter 5 blocked, arriving through new doors.
- Practice areas you don't handle. An injury campaign on broad match will meet workers' compensation, Social Security disability and medical malpractice searches. Some firms want them. Many don't. Decide case by case and block the rest.
- Winners. A search that keeps producing qualified consultations gets promoted into the Isolation campaign as an exact match keyword, where it gets its own bid and, if it's big enough, its own ad group.
Here's what that looks like in practice. "Lyft driver hit me while I was walking" is a pedestrian case with rideshare insurance behind it: keep it, and watch whether it converts. "How to become a personal injury lawyer" is a law student: block it. "Uber accident settlement amounts" is someone still researching: leave it running for now, and block it if it keeps spending without producing a consultation. The decision is always the same question: could this person become a client of this firm this month?
Google also offers search terms insights, which group searches into themes and account for some low-volume searches the report leaves out. It's a useful second look. It isn't a substitute for reading the actual terms.
After the first month, the daily read becomes weekly. It never stops. The searches change with the news, the season and the next rideshare headline.
Once Broad Match Signs Cases, the Exact Match Campaign Becomes the Backup, Not the Engine.
Isolation and Exploration aren't permanent roles. They're a balancing act.
Early on, Isolation carries the account: it's the only campaign with enough data to trust. Once Exploration is signing cases at a cost per acquisition the firm likes, it often carries more of the volume, and the Isolation campaign can be paused. Watch two numbers before making that call: the cost per qualified consultation in each campaign, and the share of signed cases each one produces. When Exploration wins both for a couple of months running, Isolation has done its job. It isn't deleted. If a rival later grabs the top spot on "truck accident lawyer," the exact match campaign gets switched back on so a hand-set bid can win it back.
The order of the rollout doesn't change. Performance Max waits months longer, and AI Max comes last of all, as Chapters 10 and 13 explain.
A Broad Match Campaign Needs a Bid Plan Before It Needs a Budget.
Exploration's target comes from what the Isolation campaign actually paid for a qualified consultation, and that number depends on how the bids were set in the first place. Chapter 7 covers manual bids by practice area, the impression share columns that show whether you're winning the top of the page, and when to hand the bidding to Google.
