Google Ads for Solicitors: Campaign Structure, Keywords, and Lead Quality Optimisation

Overview

A practical law firm Google Ads plan begins with one question: which type of enquiry can the firm handle profitably and compliantly? “Legal advice” is too broad for a useful campaign. A family law campaign, for example, may need different keywords, exclusions, ad copy, qualification questions and response processes from a conveyancing campaign.

Separate campaigns where the commercial or operational assumptions differ. A simple structure might look like this:

Account
├── Family law | City or service area
│   ├── Divorce keywords
│   ├── Children and arrangements keywords
│   └── Financial settlement keywords
├── Conveyancing | City or service area
│   ├── Residential sale keywords
│   └── Residential purchase keywords
└── Employment law | City or service area
    ├── Employee enquiries
    └── Employer enquiries

This separation makes it easier to control budgets, match adverts to search intent, send visitors to relevant legal landing pages and identify which services produce qualified conversations. It also avoids treating every click or form submission as an equally valuable lead.

Google Ads interfaces and settings change over time. Check the current platform guidance before applying instructions, and have a suitably qualified person review claims, privacy notices, consent mechanisms and professional conduct requirements. In the UK, firms should also check that campaigns and landing pages remain consistent with applicable SRA expectations and data-protection obligations.

How to estimate

Use a simple funnel model before setting a monthly budget. The model is not a forecast; it is a decision tool that shows which assumption is driving the result.

1. Estimate available clicks: budget divided by assumed average cost per click.
2. Estimate enquiries: clicks multiplied by the landing-page enquiry rate.
3. Estimate qualified leads: enquiries multiplied by the proportion that meet your service, location, urgency and eligibility criteria.
4. Estimate new matters: qualified leads multiplied by the proportion that become clients.
5. Calculate cost per qualified lead: advertising spend divided by qualified leads.
6. Calculate cost per new matter: advertising spend divided by new matters.

For example:

Clicks = budget ÷ assumed cost per click
Enquiries = clicks × enquiry rate
Qualified leads = enquiries × qualification rate
New matters = qualified leads × instruction rate

Do not set an acceptable cost per lead in isolation. Compare the estimated cost per new matter with the value, capacity and risk profile of the service. A lead may be affordable but operationally unhelpful if it concerns a service the firm does not accept, arrives outside its geographic area or cannot be handled promptly.

Keyword planning worksheet

Prioritise phrases that identify a service and a need, rather than building a list solely from broad legal terminology. Review actual search terms after launch; the wording people use may differ from the initial plan.

Inputs and assumptions

Record assumptions in a shared sheet so that changes can be traced. Useful inputs include:

• Budget: the amount available for media, separated from management, creative, tracking or landing-page costs.
• Click cost: an assumption to test, not a guaranteed rate. It can vary by service, location, competition, device and auction conditions.
• Enquiry rate: define what counts as an enquiry: completed form, tracked call, booking or another meaningful action.
• Qualification rate: the percentage of enquiries that fit the firm’s service, territory, timescale and client criteria.
• Instruction rate: the percentage of qualified opportunities that become clients. This should come from the firm’s own intake records when enough data exists.
• Capacity: the number of additional matters the firm can handle without weakening service quality.
• Tracking coverage: whether calls, forms, booking journeys and offline outcomes are recorded reliably and lawfully.

Negative-keyword checklist

Build an exclusion list before launch and expand it from search-term reviews. Consider whether the campaign should exclude searches containing:

• jobs, careers, vacancies, training or courses;
• free templates, sample letters, precedents or academic research;
• legal definitions where no service enquiry is intended;
• services the firm does not provide;
• locations outside the firm’s service area;
• requests for a different client type, such as employer searches in an employee-only campaign;
• queries that reveal an issue the firm cannot accept or is not authorised to handle.

Exclusions need judgement. A word that is irrelevant in one campaign may be valuable in another, so review the full search phrase and resulting lead before adding a negative keyword.

Ad and landing-page alignment

Each advert should accurately describe the service, location and next step. Avoid guarantees, unsupported superiority claims, artificial urgency or wording that could mislead a prospective client. The landing page should repeat the relevant service in plain language, explain who the firm helps, provide a clear contact route and set realistic expectations about response times and the nature of any initial contact.

Use a privacy notice that matches the data being collected, avoid asking for unnecessary sensitive information at the first stage and make sure call and form tracking has an appropriate legal and operational basis. For more on page structure, see the guide to solicitor landing pages and the SRA-compliant solicitor marketing checklist.

Worked examples

These figures are illustrative assumptions, not market benchmarks. Suppose a firm allocates 1,200 currency units to one practice-area campaign and uses an assumed average click cost of 12 units.

The useful conclusion is not that these results will repeat. It is that improving qualification or instruction can matter as much as reducing click cost. If six enquiries produce only one qualified lead, investigate targeting, keyword intent, advert clarity and the intake questions before simply increasing spend.

When comparing services, keep the same definitions. “Lead” might mean a form completion in one report and a screened, relevant conversation in another. Use separate columns for raw enquiries, valid enquiries, qualified leads, consultations and new matters.

When to recalculate

Review the campaign at least monthly, with more frequent checks where spend is material or the service is urgent. Recalculate the model when any of these inputs changes:

• the advertising budget or campaign priority;
• observed click costs, search demand or auction conditions;
• landing-page conversion or call-answering performance;
• qualification rules, service areas, opening hours or available capacity;
• the proportion of qualified leads that become clients;
• a new practice area, location, advert, landing page or tracking method;
• platform settings, advertising policies, privacy requirements or consent arrangements.

Monthly optimisation template

Keep a dated record of each change and its reason. Paid search becomes more manageable when decisions are tied to qualified legal leads and new matters, rather than clicks alone. For measurement beyond the advertising account, use the solicitor website analytics guide and review response speed using the law firm intake optimisation playbook.

Before the next reporting cycle, update the assumptions, check the search-term report, sample lead records and confirm that each campaign still reflects the firm’s services and capacity. That repeatable process is the foundation of responsible legal PPC management.
