Keyword match types
Which keyword match types should a law firm use in Google Ads?
Exact, phrase and broad match as Google defines them today, why we launch law firm accounts on exact match, and when broad match earns a test.

The short answer
If you read one part of this page, read this.
Start a law firm's Google Ads account on exact match only, with one exact keyword for every way people really type the case type in your area. Move to phrase or broad match later, and only as a test, once the campaign has real lead history and someone reads the search terms every week.
Exact match is not as narrow as it sounds. Google matches it to searches with the same meaning, including plurals, misspellings and reordered words, so you still reach the person who types "lawyers for dui". What it keeps out is the guesswork: phrase and broad match let Google decide a search is close enough, and in legal searches that often means paying $50 or more a click for another firm's name.
Broad match is Google's default and its recommendation, paired with Smart Bidding. That pairing needs conversion data a new legal account doesn't have yet. We work with law firms across the US and Canada, and also in Australia and the UK.
The three match types
Exact matches the meaning, phrase includes it, broad goes wherever Google thinks is related.
Each match type tells Google how close a search must be to your keyword before your ad can enter the auction. The difference between them decides how much of your budget goes to searches you never chose.
| Match type | How you write it | What Google says it matches | Could show for |
|---|---|---|---|
| Exact | [dui lawyer] | Searches with the same meaning or same intent as the keyword | "dui lawyers", "lawyer for dui", "dui lawyr" |
| Phrase | "dui lawyer" | Searches that include the meaning of the keyword | "dui lawyer cost tampa", "best dui lawyer reviews", "dui lawyer jobs" |
| Broad | dui lawyer | Searches related to the keyword, including ones without its direct meaning | "reckless driving charge", "license suspended what now", another firm's name |
Broad match is the default. Google says every keyword you add is broad unless you set another type, "because it is the most comprehensive." So an account somebody built in an afternoon is usually a broad match account, whether they meant it or not.
Google also notes that broader types capture everything the narrower ones do: a broad keyword matches all the searches its phrase and exact twins would, plus more. That's the pitch for broad. For a law firm it's the warning, because the "plus more" is where the money goes.
Close variants
Exact match still covers plurals, misspellings and same-meaning searches.
Google matches every match type to close variants, and there is no way to opt out. For exact match that means the same search said slightly differently, not a different search.
Google's close variants page lists what exact match can include: misspellings, singular and plural forms, stemmings, abbreviations and accents, reordered words with the same meaning, added or removed function words like "for" or "in", and implied words. It also gives a same-meaning example: an exact keyword for "bathing suits" can show for "swimming suits".
In practice, [custody lawyer] can show for "custody lawyers" or "lawyer for custody". In the search terms report those rows are labeled as close variants of your exact keyword, so you can see exactly what Google treated as the same search.
Why we start on exact
Legal clicks are too expensive to let Google guess which searches are close enough.
When a click costs as much as a lunch meeting, every loose match is a real line item. Exact match keeps the budget on the searches you chose while the account has no history to learn from.
In our October 11, 2026 Keyword Planner pull for Texas, the going range to show above the regular results for "personal injury lawyer" was $96.88 to $445.03 a click. Even "divorce lawyer" sat at $7.52 to $45.51. Our budget by practice area guide has the full table.
We learned the phrase match lesson on a live injury account. Of the five paid searches Google showed us with spend, three were other lawyers' names, and all three came through phrase keywords. The phrase keyword contained "car accident lawyer"; the searches contained a competitor's name next to it. Google counted that as including the meaning.
So every keyword we launch is exact, for every client, unless the firm decides otherwise for a specific reason. The same rule sits in our Google Ads build checklist, and a separate check reads every keyword before anything is switched on.
How we build the exact list
Fewer keywords, more data on each, and every one names the case type.
An exact match account only works if the list covers the real ways people search. Here is the order we follow when we set up a new case type.
Pull the searches for the case type in the firm's own area
We use Keyword Planner for the counties or cities the campaign will target, not the whole country. Google says its search volume counts exact matches only, and it folds close wordings together, so "dui lawyer" and "dui attorney" often show the same number. That number is one pool of searches, not two.
Collapse the variants into a few main searches
Dozens of planner rows are usually three or four real searches said different ways. We pick those heads first, then decide which variants deserve their own exact keyword.
Add every same-intent variant as its own exact keyword
Near me forms, plurals, "law firm" and "attorney" versions, the state, and the firm's own cities and counties. One DUI campaign reached our pre-launch check without "dui lawyer near me", which had more searches in its area than any keyword on the list. Wording like crash, wreck and collision goes in when people in that area actually use it.
Make sure each keyword names the case type
"accident lawyer near me" sounds close to "car accident lawyer near me", but it matches any accident at all. We pause vague keywords like that, even as exact.
Keep sub-types for their own ad group
Truck, rideshare or motorcycle searches inside an injury campaign get their own ad group and page once the main group runs, so the ad and page can speak to that case.
Hold adjacent searches to watch, not to block
Searches with "settlement", "insurance claim", "cost" or "how much" in them are often people about to hire. We leave them out of the launch, watch for them in the search terms report, and never block them by default.
Don't add the same keyword in all three match types "to cover everything". Google says near-identical keywords compete with each other, and only the one with the higher Ad Rank is used, so you get one bid and the data split three ways.
Checking the matches
The search terms report shows what you actually paid for.
Your keyword is what you chose; the search term is what the person typed. The report shows the second, with a match type column that tells you how Google connected the two.
Google omits some low-volume searches from the report for privacy, so it never shows every search. It still shows enough to spot a pattern, and the patterns are what matter: other firms' names, the wrong case type, the wrong side of the case, places outside your area, and students or job seekers.
- Weekly for the first two months
We read it every week while a campaign is new, and add negatives for anything that should never have matched. Our negative keywords guide has the lists and the routine.
- Judge the keyword, not one bad search
A single odd search is noise. The same kind of search repeating under one keyword means that keyword, or its match type, is the problem.
- Wait for enough clicks
We don't judge a keyword's lead rate on fewer than about 40 clicks. At legal click prices, that can take weeks for a smaller budget, which is one more reason to keep the list lean.
When broad match makes sense
Broad match needs Smart Bidding, and Smart Bidding needs real leads to learn from.
Google says "It's critical to use Smart Bidding with broad match." That's honest advice, and it's also the reason broad match doesn't fit a new legal account.
Smart Bidding, which includes Maximize conversions and Target CPA, sets a bid for each auction based on how likely that search is to convert. Google says the learning period depends on how many conversions a campaign gets and how long its conversion cycle runs. A campaign with one lead has almost nothing to learn from.
We've seen what happens when it's rushed. A new injury campaign switched to Maximize conversions with one lead of history showed 7 times in 2 days. So new campaigns start on Maximize clicks with a cost per click cap, and move to Maximize conversions after about 30 leads.
- About 30 or more real leads, counted from the CRM, not page views or button clicks.
- Signed cases or qualified leads sent back to Google, so it learns which leads mattered. Our Google Ads call tracking guide covers this.
- A mature negative list, built from months of real search terms.
- Someone reading the search terms every week while the test runs.
- A test on part of the budget with a fixed end date, compared on cost per signed case.
Google's AI Max for Search campaigns is a setting that adds broad match style search term matching, rewritten ad text and final URL expansion to a Search campaign. We treat it the same way as broad match: a test for a mature account, never a launch setting. Performance Max has its own version of the trade-off, covered in our Performance Max guide.
What changes the answer
Market size, lead history and the practice decide how loose you can go.
Exact match first is the rule. These are the situations where we bend it, and how far.
| Situation | What we use | Why |
|---|---|---|
| New campaign, no lead history | Exact only | Nothing for Smart Bidding to learn from; every loose match is paid for blind |
| Small town or narrow case type, little volume | Exact, plus phrase on one or two main searches if the firm decides so | Exact alone may not spend; phrase widens it while the search terms are watched weekly |
| About 30+ leads a month, signed cases tracked | Exact core, with a broad match test on part of the budget | Enough data for Smart Bidding to tell good searches from bad |
| Injury, DUI and other high-cost markets | Exact for longer | At $50 to $400 a click, a few loose matches a day is a large monthly cost |
| Canada, the UK or Australia | The same rules | Match types work the same way in every country; only the searches and prices change |
Practice matters too. Injury, criminal and immigration searches often carry another firm's name or a wrong case type right next to the words you want. Estate planning and business searches tend to mix with research and DIY. Our practice pages, like personal injury marketing and DUI defense marketing, cover how clients there search.
A worked example
A hypothetical DUI solo with $2,500 a month.
An illustration, not a result. The firm and every number here are made up to show the arithmetic.
Real results come from the whole system, not the match type alone. A Toronto real estate solo with no online presence generated $10,875 in the first week on Google search ads, from just over $300 in ad spend, with a lean keyword list pointed at one case type.
Common mistakes
Where firms go wrong.
The match type mistakes we find most often when a firm hands us an existing account.
Leaving every keyword on the default
Broad match is what Google sets unless you choose otherwise. Many accounts we audit are broad match by accident, not by decision.
Phrase matching short, vague keywords
A phrase keyword like "injury lawyer" matches any search that includes that meaning, including other firms' names and case types you don't take.
Switching to broad match and Smart Bidding too early
With a handful of leads, Smart Bidding is guessing. Build the history on exact match and a click cap first.
Adding the same keyword in every match type
Google uses only one of them in each auction. It splits the data and adds nothing.
Never opening the search terms report
Match types are a promise about which searches you'll pay for. The report is the only place you can check it was kept.
Real results
What this looked like for real firms.
A Google search ads result built on a lean keyword list, and a firm whose case quality changed once the targeting was tightened.

FAQ
Questions lawyers ask us.
Straight answers to the questions that come up most.
Isn't exact match too restrictive for a law firm?
Not usually. Exact match still matches plurals, misspellings, reordered words and same-meaning searches, so "lawyer for custody" can still trigger [custody lawyer]. What it leaves out are related searches Google guesses at. If a small market can't spend the budget on exact, we add phrase match to one or two main searches and watch them weekly.
Google keeps recommending broad match. Why not take it?
Google pairs that advice with Smart Bidding, which learns from conversions. A new legal account has few or none, so broad match runs with little to steer it. Once an account has around 30 leads a month and signed cases flowing back from the CRM, a broad match test can be worth running on part of the budget.
Do match types change my Quality Score?
No. Google says Quality Score is based on past impressions for exact searches of the keyword, so changing the match type doesn't change it. What changes is which searches you pay for, and that shows in your click rate and leads.
What is AI Max, and should I turn it on?
AI Max for Search campaigns is a Google setting that widens search term matching, rewrites ad text and can send people to other pages on your site. It acts like broad match plus more. We leave it off at launch and only test it on accounts with solid lead history and tracking.
Should I bid on other law firms' names?
We don't by default, and we block competitor names on launch. Someone who typed another firm's name is usually trying to reach that firm, so the click rarely becomes your case. Our guide to bar rules for law firm ad copy covers what your ads may say.
How many keywords should a law firm start with?
Fewer than most expect. A single case type in one area often launches with around 10 to 30 exact keywords, all variants of a few real searches. More keywords means less data on each, and slower decisions.
How long before I know if the match types are right?
The search terms report shows problems within days. Lead rate needs about 40 clicks per keyword before it means much, which can take a few weeks at legal prices. Our guide on how long law firm marketing takes covers the wider timeline, or you can schedule a consultation for a look at your account.
