Short answer: PPC has its place, but for most UK law firms organic search and the map pack pay back better over time. Paid search buys visibility today. SEO and local search build an asset that keeps bringing enquiries in after the spend stops.
I don’t run Google Ads for clients, so I’ve no reason to talk it down. I’ve seen it work well for firms, and I’ve seen it quietly eat a marketing budget. Here’s how I’d think about the choice.
What a click actually costs a UK law firm
Legal searches are expensive on Google Ads. These are Google’s own estimates for UK searches:
| Search | UK searches a month | Estimated average cost per click |
|---|---|---|
| no win no fee solicitor | 12,100 | £60.98 |
| personal injury solicitor | 2,400 | £65.75 |
| divorce solicitor | 2,900 | £27.27 |
| probate solicitor | 2,900 | £23.36 |
| conveyancing solicitor | 9,900 | £22.70 |
| immigration solicitor | 3,600 | £17.84 |
| employment solicitor | 1,600 | £17.77 |

What a click costs on Google Ads (UK)

Those are clicks, not enquiries. Purely as an illustration: if one in ten clicks turns into an enquiry, and one in three enquiries instructs, a £25 click costs you £750 per new client before any fees are earned. Your own numbers will differ, so work the sum with your real conversion rates before you commit.
Where PPC earns its place
- A new office or a new practice area. Organic rankings take months. Paid search can test demand in a new town or service in weeks.
- Short, high-value windows. A change in law or a seasonal spike, such as January divorce enquiries, where you need visibility now.
- Searches where you can’t rank yet. National brands and claims businesses dominate some personal injury and no win no fee results. A tightly controlled campaign can buy a place there while the organic work builds.
- Learning what converts. Paid search data tells you quickly which searches and landing pages turn into instructions. That’s useful for planning the organic work too.
Why organic and local usually pay back better
- The map pack shows on most local legal searches. In my August 2026 study, a local pack appeared on 20 of 24 consumer legal searches. Ranking there depends on your Google Business Profile, reviews and local relevance, not on ad spend. See why the local pack decides so many legal searches.
- The cost doesn’t reset every month. Turn ads off and the enquiries stop the same day. A well-built practice-area page keeps ranking.
- AI assistants draw on organic sources. ChatGPT, Perplexity and Google’s AI Overviews cite pages and profiles they can read and trust. You can’t buy your way into those answers with Google Ads. More on that in SEO vs AI search visibility.
- Trust. Some people skip the ads and click the first organic result or the map listing, particularly for sensitive matters like divorce or probate.
The catch is time. Organic results take months to build, and how long depends on your practice area and starting point. I’ve set out realistic timelines in how long SEO takes for a law firm.
The SRA rules apply to ads and organic pages alike
An ad is publicity, so the same rules apply as on your website.
- Accuracy. Paragraph 8.8 of the SRA Code of Conduct requires that “any publicity in relation to your practice is accurate and not misleading, including that relating to your charges”. Ad copy promising outcomes, or quoting a fee that leaves out VAT or disbursements, is a risk.
- Price information on landing pages. For conveyancing, uncontested probate, some immigration work, some employment claims and the other services the SRA Transparency Rules list, cost information must be “clear and accessible and in a prominent place on your website”. A PPC landing page that hides it doesn’t remove the duty.
- No cold approaches. Paragraph 8.9 bars unsolicited approaches to members of the public to advertise legal services, other than to current or former clients. Search ads respond to someone who is already searching, so they’re a different thing, but be careful with remarketing lists and bought data.
I go through the website side of this in the SRA Code of Conduct and your law firm website.
A sensible split for most firms
- Firms with a strong local base: put the effort into organic and the map pack first, and use a small, tightly targeted paid budget only for gaps.
- New offices or services: run paid search for a fixed test period while the local and organic work beds in, then review.
- High-cost practice areas such as personal injury: only run ads if you know your cost per instruction and can measure it. Otherwise the money is better spent on pages and reviews that keep working.
Whichever route you take, track enquiries back to the source. If you can’t see which searches lead to instructions, you can’t tell whether either channel is paying for itself.
Should you run Google Ads in-house or use an agency?
If your search volumes are small and your team has time to learn the platform, in-house can work. Bigger spends usually justify a specialist, but ask how they report cost per enquiry and cost per instruction, not just clicks. Whoever runs it, someone at the firm needs to sign off ad copy against the SRA rules above. I don’t offer PPC management myself.
Frequently asked questions
Is PPC or SEO better for a law firm?
For most UK firms, SEO and local search pay back better over time, because the results keep working after you stop spending. PPC is useful for speed, for testing a new office or service, and for filling gaps while organic rankings build.
How much does Google Ads cost for solicitors in the UK?
Google’s estimated average cost per click for UK legal searches ranges from about £18 for “employment solicitor” to over £60 for “personal injury solicitor” and “no win no fee solicitor” (Keyword Planner estimates via DataForSEO, October 2026). Actual costs vary. What matters is the cost per instruction, which depends on your conversion rates.
Do the SRA rules apply to Google Ads?
Yes. Ads are publicity, so paragraph 8.8 of the SRA Code of Conduct applies: they must be accurate and not misleading, including about charges. If you advertise services covered by the SRA Transparency Rules, the landing page must show the cost information prominently.
Can I run PPC and SEO at the same time?
Yes, and many firms do. Use paid search for speed and testing, and let what you learn shape the organic and local work, which builds value over time.
Does Google Ads help my firm appear in ChatGPT or AI Overviews?
No. AI assistants and AI Overviews draw on organic web pages, profiles and reviews. Ad spend doesn’t buy a place in those answers.
