Negative Keywords for Law Firm Google Ads: A Practical Search-Term Review Framework

Negative keywords should stop a law firm paying for searches it cannot or does not want to serve. They should not become a blunt list that quietly blocks valuable enquiries.

The most reliable approach is to review the actual search terms behind calls, forms, consultations and new instructions, then classify each query as Take, Test or Exclude. That puts commercial judgement ahead of a generic “negative keyword list”.

What is the difference between a keyword and a search term?

A keyword is a targeting instruction added by the advertiser. A search term is what the prospective client actually typed into Google.

That distinction matters because modern keyword matching can connect an advert with searches that are not identical to the keyword. A campaign may target “employment solicitor”, while the search-terms report reveals traffic for employer advice, employee settlement agreements, free templates, training courses, salaries or jobs.

Some of those searches may be valuable. Some are clearly irrelevant. Others need evidence before a decision is made.

Google’s search-terms report is therefore not merely a list of wording variations. It is a record of the market intent the campaign is actually buying.

What should a law firm use negative keywords for?

Use negatives to remove intent that is demonstrably outside the firm’s offer, geography or commercial criteria.

Typical examples include:

• services the firm does not provide;
• searches from the wrong side of a matter where the firm only acts for one side;
• careers, salaries, courses and training searches;
• templates, definitions or academic research with no realistic route to instruction;
• jurisdictions the firm cannot serve;
• another practice area leaking into a tightly focused campaign;
• repeated terms that generate enquiries the intake team consistently rejects.

The last point is important. A query is not waste merely because it looks untidy in Google Ads. It becomes a strong exclusion candidate when search intent and downstream outcomes agree.

The Take, Test or Exclude framework

Every meaningful search term should have one of three outcomes.

This is more useful than dividing terms into “good” and “bad”. Legal searches are often compressed descriptions of complicated situations. A person can use imprecise language and still need exactly the work a firm provides.

Take: protect and develop the right intent

Suppose a contentious-probate campaign repeatedly receives searches for “inheritance dispute solicitor”. The term matches the target service, the geography is valid and the enquiries are suitable. That is not only a search term to keep. It may deserve its own ad group, advert language and page section.

Search-term review should therefore find opportunities as well as waste.

Test: do not exclude uncertainty too quickly

“Can I contest a will” appears informational, but it may come from somebody at the beginning of a genuine dispute. Whether it is valuable depends on the firm’s offer, the page, the enquiry path and what those visitors do next.

A controlled test can answer the question. Review the term against engagement, enquiry quality and consultations — not merely click-through rate.

Exclude: remove intent the firm cannot convert

“Probate solicitor jobs” is unambiguous in a client-acquisition campaign. So is a location the firm cannot serve or a legal service it does not offer.

Those exclusions protect budget and make the remaining data easier to interpret.

Why generic legal negative-keyword lists can be dangerous

A downloaded list has no understanding of the firm’s practice, funding model, content strategy or intake criteria.

Consider four commonly suggested negatives:

• free — often low commercial intent, but potentially relevant to a firm offering a defined free initial call;
• cost — a strong research signal, but also a natural question from a serious prospective client;
• legal aid — irrelevant for many firms, essential context for others;
• template — usually unsuitable for managed legal work, but not automatically irrelevant if the page intentionally converts self-help researchers into advice enquiries.

The right question is not “Does this word look cheap?” It is “Does this search have a credible route to a matter we would take?”

Start with evidence. Add exclusions narrowly. Check the effect.

Where should negative keywords be applied?

The level matters because the same word can be irrelevant in one campaign and commercially useful in another.

Account or shared-list negatives

Use these for intent that is genuinely irrelevant across the whole account, such as recruitment terms where no campaign is intended to attract applicants.

Shared lists are efficient, but the blast radius is large. A term placed here should be safe across every current and planned practice area.

Campaign negatives

Use these to preserve the boundary between practice areas, locations or audiences.

For example, a commercial-litigation campaign may exclude searches clearly about family proceedings. A claimant-focused campaign may exclude employer or defendant intent if the firm does not act for that side.

Ad-group negatives

Use these to route closely related searches to the most relevant advert and landing page.

This can stop “settlement agreement solicitor” traffic being absorbed by a broader employment-law ad group when a dedicated settlement-agreement journey exists.

How do negative match types behave?

Negative match types are not simply the inverse of positive match types.

Google states that negative keywords do not match close variants in the same way positive keywords can. Synonyms, singulars, plurals and related wording may therefore need separate consideration. Adding a term directly from the search-terms report defaults to negative exact, which blocks that specific query rather than every search containing the words.

The practical rule is to use the narrowest exclusion that solves the known problem:

• negative exact for one clearly unsuitable query;
• negative phrase where the sequence consistently signals unsuitable intent;
• negative broad only where all included words together are safely irrelevant across varied word order.

Before applying a broad exclusion, test it against searches the firm does want. One careless word can suppress an entire pocket of valuable demand.

Practice-area examples: what would you do?

These examples are illustrative, not universal instructions.

The keyword research supporting Mavari’s legal strategy illustrates why precision matters. Google’s Keyword Planner showed meaningful UK demand across broad solicitor terms and specialist areas, with indicative top-of-page bid ranges varying materially by practice area during August 2025–July 2026. Those are directional planning estimates, not guaranteed click prices. Expensive demand makes waste more visible, but even a cheap irrelevant click is still waste.

How often should a law firm review search terms?

New or materially changed campaigns need closer review than mature accounts.

A sensible operating rhythm is:

• several checks during the first one to two weeks of a new launch;
• weekly review while query patterns and qualification data are still developing;
• a regular fortnightly or monthly review once the account is stable;
• an immediate review after changing match types, adding broad targeting, launching a practice area or seeing a fall in enquiry quality.

Do not treat the report as complete. Google explains that search-term reporting includes terms used by a significant number of people; some low-volume searches are omitted or grouped for privacy. Use it as a strong sample, not a perfect ledger of every query.

Why must intake and CRM outcomes be part of the review?

The search term can reveal intent, but it cannot reveal the whole outcome.

Two similar queries can produce very different enquiries. One may be in the right jurisdiction, able to fund the work and ready to book. The other may be outside scope. If both are recorded only as “form submission”, the campaign receives no useful distinction.

The review becomes more commercially useful when it can see:

That does not require confidential matter detail inside Google Ads. A controlled source identifier and a small number of consistently defined outcome fields can be enough.

A practical weekly search-term review

1. Start with spend and repeated patterns

Sort by cost, clicks and recurring wording. One strange query rarely matters as much as a theme steadily absorbing budget.

2. Check the intended practice area and side

Confirm that the term matches the service, jurisdiction and client side the campaign was built to attract.

3. Inspect the landing-page promise

A relevant query can still perform poorly if it reaches a generic page. Before excluding the term, ask whether the post-click experience answered the search properly.

4. Read the enquiry outcomes

Where available, compare the term with valid enquiries, qualification, consultations and instructions. Treat raw platform conversions as the beginning of the analysis.

5. Choose Take, Test or Exclude

Record the decision and reason. Avoid adding negatives without an audit trail.

6. Apply the narrowest safe control

Choose the correct level and match type. Check that the negative will not conflict with valuable keywords elsewhere.

7. Feed opportunities back into structure

Promote strong recurring queries into better ad groups, ads and landing-page content. Search-term work should improve relevance, not only cut traffic.

What mistakes do law firms make with negative keywords?

Adding a giant list before seeing real demand

This can block useful queries and create false confidence. Begin with unquestionably irrelevant intent, then learn from the market.

Reviewing clicks without enquiry quality

A term with a high CPC can be profitable. A cheap term can generate hours of wasted intake. Cost alone is not the verdict.

Using account-wide exclusions for campaign-specific problems

The firm may later launch the very service the shared list blocks.

Treating all informational searches as worthless

Some people research language, process and cost immediately before choosing a solicitor. The landing page and offer determine whether that early intent has a route forward.

Never revisiting old negatives

Practice areas, locations and propositions change. A previously sensible exclusion can become a silent constraint.

Forgetting location leakage

Negative keywords cannot repair weak geographic settings. Review Google’s presence options, location reports and service-area exclusions alongside query wording — see how to geo-target Google Ads for a law firm.

Frequently asked questions

Should every law firm use the same negative keyword list?

No. The safe exclusions depend on practice areas, the side the firm acts for, jurisdiction, location, funding model and the journey offered on the landing page. Reusable themes can help discovery, but every term should be reviewed against the firm’s actual offer.

Should “free” always be a negative keyword?

No. It is often a low-commercial-intent signal, but not always. If the firm offers a genuine free initial conversation or uses useful content to qualify demand, blanket exclusion may remove relevant prospects. Test it against real outcomes.

Should competitors’ names be excluded?

Not automatically. Competitor searches raise strategic, legal, cost and relevance questions. Review trademark policy, ad wording, landing-page relevance and actual enquiry quality before deciding. Do not imply affiliation.

Can negative keywords fix poor lead quality on their own?

No. Lead quality can also fail through loose location targeting, generic landing pages, weak qualification, broken tracking or slow follow-up. Negatives solve only the query-control part of the system.

How many negative keywords should a campaign have?

There is no useful target number. The goal is safe control of irrelevant intent, not a longer list. A small precise list can be stronger than hundreds of inherited exclusions.

The commercial takeaway

Negative-keyword work is not about making a campaign look tidy. It is about protecting budget for searches with a credible route to suitable legal work.

The best review combines human reading of search intent with landing-page context and intake outcomes. It finds waste, but it also discovers the language prospective clients use before they instruct.
