PPC for law firms, measured in instructions rather than clicks
PPC for law firms is paid search advertising, chiefly Google Ads, where the firm pays for clicks from people actively searching for a solicitor — or, in the same pattern, ppc for solicitors — and is judged on what those clicks become: enquiries and instructions. GrowthLine runs it for UK law firms as part of a lead-generation-only agency, working in enquiries and appointments, not ecommerce baskets. This page sets out the economics by practice area, the three faults most common in law-firm accounts, and where the fees are published.
Law firm PPC economics by practice area
Practice areas are different markets — a conveyancing click and a personal-injury click are priced and valued nothing alike, so blended averages mislead. The table below shows what the main service lines actually cost in UK Google Ads right now: monthly search demand, the average click price across all advertisers, and the low top-of-page bid — a fair guide to what a well-optimised account pays. The spread is the point: personal injury trades at more than three times the click price of employment law, and in every line a well-run account pays a fraction of the average — in family law, roughly a quarter.
| Service line | Monthly UK searches | Avg CPC | Low top-of-page bid |
|---|---|---|---|
| Personal injury | 2,900 | £74.34 | £22.71 |
| Conveyancing | 14,500 | £24.80 | £10.96 |
| Family law | 11,700 | £24.69 | £6.19 |
| Employment law | 1,600 | £21.51 | £5.72 |
| Commercial law | 1,300 | £37.97 | £9.93 |

Three problems we keep seeing in law firm accounts
Clicks that never become instructions
Most inherited law-firm accounts track a form submission at best; nothing feeds back which enquiries became instructions, or what they were worth. With clicks this expensive, an account optimised to cheap enquiries quietly fills the pipeline with cases the firm doesn't want. The fix is measurement plumbing before media decisions: enquiry source tracking, call tracking, and — where the firm can share it — instruction outcomes fed back into bidding.
One campaign covering every practice area
Conveyancing, family & matrimonial and clinical negligence carry utterly different case values and click prices; lumped into one campaign with one budget, the cheap clicks eat the budget of the valuable work and the reporting hides it. Campaigns for google ads for law firms should be separated by practice area and case value, with budgets and bids set to what each instruction is worth. This is also where searchers looking for the best-structured account land — the answer is structure, not a secret keyword list.
Generalist set-ups that treat a firm like a shop
The documented failure mode in this vertical is a generalist agency targeting the whole UK on broad match for a regional firm. Legal budgets punish missed hygiene hard: geographic targeting drawn to where the firm can actually act, match types tightened, and negatives for the searches a firm never wants to pay for — "free", "legal aid", "no win no fee" where the firm doesn't offer it. This is checklist work, and it is the first thing a free PPC audit looks at.
How reporting works
Reporting is against cost per qualified enquiry — and against instruction outcomes where the firm shares them — not clicks or impressions. Every number in a client report carries its source. The full deliverables list, engagement timeline and reporting scope are documented on the PPC management service page.
Who we're not for
We don't take criminal legal-aid work — fixed fees and case volumes rarely leave room for paid-search economics — and we don't handle ecommerce for anyone. If most of the firm's work is legal-aid funded, a directory and referral strategy will serve better than an agency retainer; saying so up front costs less than finding out in month three.

What law firm PPC management costs
There are two separate costs: media spend paid directly to Google, and the management fee. As a PPC agency for law firms, GrowthLine publishes its management fees in full — most agencies serving this market don't publish fees. See PPC management fees and pricing.

Law firm PPC FAQs
Do Google Ads work for lawyers?
Yes, when the practice area's case value supports the click price. Google Ads reaches people at the moment they search for a solicitor, which makes it the fastest paid channel for new enquiries — but legal clicks are expensive, so an account that is not measured through to enquiries and instructions burns budget quickly. Whether Google Ads for law firms pays back is arithmetic: what a new instruction is worth against what your practice area's clicks cost. A free PPC audit shows that arithmetic for your account before you commit to anything.
Are solicitors allowed to advertise?
Yes. Solicitors in England and Wales can advertise, provided the marketing complies with the SRA's codes of conduct and Transparency Rules — accurate claims, nothing misleading, and clear price information for the services the rules cover. Scotland and Northern Ireland apply equivalent rules through their own professional bodies. In practice the rules shape ad copy and landing-page claims rather than ruling out the channel: a compliant Google Ads campaign is entirely normal for a UK law firm.
How much does Google Ads cost for a law firm?
There are two separate costs: the media spend paid to Google, which varies widely by practice area, and the management fee paid to whoever runs the account. UK Google Ads data (DataForSEO, July 2026) puts the average click at £74.34 for personal injury, £37.97 for commercial law, £24.80 for conveyancing, £24.69 for family law and £21.51 for employment law — and well-optimised accounts typically pay much less, down at the low top-of-page bid shown in the table on this page. Our management fees are published in full on the pricing page.
Is £100 a day enough for Google Ads for a law firm?
Sometimes — it depends on the practice area and the geography you target. In lower-priced practice areas and local markets £100 a day can fund a meaningful test; in contested, high-value areas it may buy only a handful of clicks a day, which produces data too slowly to optimise. The honest way to answer it is backwards: start from what an instruction is worth, apply a realistic enquiry rate, and see what click price the maths can carry. Our Google Ads budget guide shows that working, and a free PPC audit applies it to your firm's account.
What does PPC stand for in law firm marketing?
PPC stands for pay-per-click: advertising where the firm pays only when someone clicks the ad, with Google Ads the dominant platform in the UK. It is not related to the professional training courses that share the acronym in the legal sector. For a law firm, PPC is best understood as buying measured introductions — the click is the cost, the enquiry is the output, and the instruction is what has to pay for both.
