Most law firms appoint an SEO agency in the same way. A partner receives three proposals, each promising more visibility, more enquiries and a dashboard of keywords. The proposals look similar, the prices do not, and the decision ends up resting on whoever presented most confidently.
Knowing how to choose a law firm SEO agency well is less about technical knowledge than about asking the right questions. You do not need to understand crawl budgets or schema markup to tell whether an agency understands how your clients choose a solicitor, how your partners work and what a genuine instruction is worth to the firm.
This guide sets out what to decide before you shortlist, what a good agency should do, the questions to ask, the red flags to watch for and a simple scoring framework for comparing proposals.
Decide what you need SEO to do first
The most common reason SEO engagements disappoint is that the firm never agreed what success looked like. Before speaking to any agency, agree internally:
- Which practices matter most. SEO effort should follow the work the firm wants more of, not the practices with the most search volume. A firm that wants more private client and contentious probate work needs a different plan from one that wants employer-side employment instructions.
- Where your clients are. A high street firm competing in two towns, a regional firm across a county and a London firm serving international clients have very different search landscapes.
- What the website must achieve. For some firms, search should generate direct enquiries. For others, mostly commercial firms, the bigger value is being visible when referrers, in-house counsel and journalists check names and expertise.
- Who owns it internally. SEO needs input from partners and someone with authority to approve content. Without an internal owner, even a good agency will stall.
- What you can realistically spend, and for how long. SEO compounds over months, not weeks. A budget that can only be sustained for a quarter is better spent elsewhere.
A good agency will ask about all of this in its first conversation. If it moves straight to keywords and packages, that tells you something.
Specialist agency, generalist agency or in-house?
| Option | Works well when | Watch for |
|---|---|---|
| Legal-specialist agency or consultancy | You want people who already understand legal buyers, regulation and partner dynamics | Some specialists work for many competing firms; check for conflicts |
| Generalist SEO agency | The firm has a strong in-house marketing team to provide legal context | Generic content, consumer-style tactics and a long learning curve |
| In-house hire | The firm is large enough to sustain a dedicated role, often alongside an agency | One person rarely covers technical SEO, content and digital PR equally well |
| Freelance consultant | You need strategy, audits or a specific project | Capacity, continuity and cover during absence |
Many mid-sized firms use a combination: an in-house marketing lead who owns priorities and approvals, with external specialists for strategy, technical work and content.
What a good law firm SEO agency should cover
Whatever the model, the work should span:
- Technical foundations: site speed, mobile performance, indexing, structured data, redirects and site architecture.
- Practice and sector pages: substantial pages that explain how the firm helps with specific client problems, written or edited by people who understand the law.
- People pages: lawyer profiles structured so that search engines and clients can connect named experts with the work they do.
- Local visibility: an accurate Google Business Profile for each office, consistent firm details across directories and genuine client reviews.
- Authority: coverage, links and mentions earned through legal commentary, directories and relationships, not bought links.
- AI visibility: how the firm appears when prospective clients ask ChatGPT, Gemini or Google's AI Overviews to recommend solicitors in a practice area.
- Measurement: tracking enquiries and instructions, not only traffic and rankings.
Our law firm SEO service is built around this scope. If your website itself needs work first, our guide to what makes a good law firm website is a useful place to start.
How to judge whether an agency really understands law firms
Almost every agency that pitches to law firms describes itself as experienced in the sector. These are the tests that separate genuine understanding from a sector page on their website.
They understand how legal clients search and choose
Ask them to describe how a client finds a solicitor in your main practice areas. A good answer distinguishes between urgent consumer searches ("emergency injunction solicitor"), considered private client research, and commercial buyers who rarely search for a firm at all but check one after a referral. If every practice gets the same plan, the plan is generic.
They understand the regulatory context
Legal marketing operates under rules that most consumer marketing does not. A credible agency should be comfortable with:
- the SRA Code of Conduct requirement not to mislead clients, which applies to claims about expertise, outcomes and experience
- SRA Transparency Rules content, including price and service pages, which are often among a high street firm's most important search pages
- the Digital Markets, Competition and Consumers Act 2024, which makes fake reviews and concealed incentivised reviews explicitly unlawful
- confidentiality, so that case studies and matter descriptions are anonymised or approved
An agency that suggests buying reviews, publishing outcome claims you cannot support or describing lawyers as "specialists" without basis is creating risk for the firm, not visibility.
They can work with partners
The best SEO content in the legal sector draws on lawyers' knowledge. Ask how the agency gets that knowledge without consuming partner time: short interviews, structured briefs, sensible approval stages. An agency that expects partners to write everything, or that publishes without legal review, will either stall or create problems.
They are open about conflicts
Specialist agencies often work with several firms. That is not a problem in itself, but you should know whether they act for a direct competitor in the same practice and location. Ask directly, and agree how conflicts will be handled.
Questions to ask before you appoint
Use these in pitch meetings. Several reflect the questions Google itself suggests asking any SEO provider.
- What would you prioritise for our firm in the first 90 days, and why?
- Which law firms have you worked with, in which practices and locations? Can we speak to one?
- Do you act for any firm that competes with us in the same practice and area?
- How do you follow Google's Search Essentials, and how do you build links and authority?
- Who will actually do the work, and who will we deal with day to day?
- How will you write or source legal content, and how will our lawyers review it?
- How do you handle SRA requirements and review content for misleading claims?
- What results would you expect, over what timeframe, and how will you measure them?
- What will your monthly report include, and how will it connect to enquiries?
- Will you share every change you make to our website and accounts?
- Who owns the content, accounts and data if we part ways?
- What is the minimum term, and what are the notice and exit arrangements?
The quality of the answers matters more than their length. Specific, honest answers, including "it depends, and here is what it depends on", are a good sign.
Red flags
- Guaranteed rankings. No one can guarantee positions on Google. Google itself warns against any provider that claims to.
- Secrecy about methods. If an agency will not explain how it builds links or what it changes on your site, assume the worst.
- Bought or bulk links. Link schemes can damage visibility, and recovering from them is slow.
- Mass-produced content. Thin, templated or unreviewed AI-written practice pages undermine credibility with clients as well as search engines.
- Reporting that stops at rankings. A rising keyword chart means little if enquiries are flat.
- Long lock-in with no exit route. Twelve-month minimum terms with no performance review protect the agency, not the firm.
- Accounts in the agency's name. Your analytics, Search Console and Google Business Profile should belong to the firm.
- One plan for every practice. Family, commercial property and immigration clients search in very different ways.
What good reporting looks like
| Weak reporting | Useful reporting |
|---|---|
| Hundreds of tracked keywords | A focused set of searches tied to priority practices and locations |
| Traffic totals | Traffic to the pages that matter: practice, people and contact pages |
| Rankings in isolation | Visibility alongside enquiries and, where possible, instructions |
| A list of tasks completed | What changed, why it matters and what happens next |
| Generic monthly PDF | A short commentary a partner can read in five minutes |
The best reports connect SEO activity to the firm's pipeline. That usually requires enquiry tracking on the website and, ideally, a link to the firm's CRM or intake records so that the source of each new matter is recorded.
Pricing, contracts and ownership
Law firm SEO is usually sold as a monthly retainer, sometimes with an initial audit or set-up fee. Published UK pricing varies widely. Local, single-office firms are commonly quoted from around £750 to £2,000 a month, while competitive regional or national work often runs to several thousand pounds a month or more. Price alone says little about value; what matters is what the retainer buys.
Before signing, confirm:
- Scope: what is delivered each month, such as content, technical work and outreach, and what is excluded
- Term: the minimum period, notice period and any break clause after an initial review
- Ownership: that the firm owns all content, data and accounts, including Google Analytics, Search Console and Google Business Profile
- Access: that the agency uses user permissions on your accounts rather than owning them
- Exit: what handover the agency will provide if the relationship ends
If your website needs rebuilding, factor that in first. Our guide to law firm website design costs in the UK explains how build budgets work.
A note on "best law firm SEO agencies" lists
Searching for the best law firm SEO agencies or best law firm SEO companies returns many ranked lists. Use them with care. Many are published by agencies that place themselves first, and some are directories where positions are paid for or influenced by advertising. US-focused lists are also common and often irrelevant to UK firms.
These lists can help build a longlist. They should not decide your shortlist. Speaking to firms that have used an agency, ideally firms of a similar size and practice mix, is far more reliable.
A simple shortlisting scorecard
Score each agency from 1 to 5 against these criteria, then multiply by the weighting.
| Criterion | Weighting | What to look for |
|---|---|---|
| Understanding of legal clients and regulation | 25% | Practice-specific thinking, SRA awareness, credible legal content |
| Strategic fit | 20% | A plan built around your priority practices and locations |
| Content quality | 20% | Samples that a partner would be happy to put their name to |
| Transparency and reporting | 15% | Clear methods, honest timeframes, reporting tied to enquiries |
| Commercial terms | 10% | Fair term, clear scope, firm owns everything |
| Working relationship | 10% | Named team, realistic demands on partner time, good chemistry |
A strong agency will score well on the first three. If the highest-scoring proposal is also the cheapest, check the scope again.
Common mistakes when appointing an SEO agency
- Choosing on price or presentation. The most polished pitch is not always the best partner.
- Letting the agency set the priorities. The firm should decide which work it wants more of.
- Skipping references. A twenty-minute call with an existing client is the best due diligence available.
- Ignoring the website. SEO cannot compensate for a slow, thin or poorly structured site.
- Underestimating partner input. Expertise has to come from somewhere. Plan for it.
- Judging too early, or too late. Agree review points at three, six and twelve months, with measures set in advance.
Frequently asked questions
How much does a law firm SEO agency cost in the UK?
Most UK agencies charge a monthly retainer. Local, single-office firms are commonly quoted from around £750 to £2,000 a month. Competitive regional or national campaigns often cost several thousand pounds a month or more. Compare what each retainer actually delivers rather than the headline figure.
How long does it take to see results from law firm SEO?
Technical fixes can have an effect within weeks, but meaningful improvement in visibility and enquiries usually takes several months. It depends on competition in your practice areas and locations, the state of your website and how consistently content is produced. Be cautious of any agency that promises fast results.
Do we need a specialist legal SEO agency?
Not necessarily, but it helps. A specialist should already understand legal buyers, SRA requirements and how to work with partners. A generalist can do good work if your in-house team provides the legal context and approves content.
Can an SEO agency guarantee first-page rankings?
No. Google warns against providers that guarantee rankings. A credible agency will explain what it expects to achieve, over what period, and how it will measure progress.
What should a monthly SEO report include?
Visibility for priority practice and location searches, traffic to key pages, enquiries generated, work completed, what it achieved and the plan for the next month. It should be short enough for a partner to read quickly.
Should our firm own its SEO content and accounts?
Yes. The firm should own its website content, Google Analytics, Search Console and Google Business Profile. Agencies should be given access, not ownership.
Can law firm SEO be done in-house?
Partly. Larger firms often keep strategy, priorities and approvals in-house and use external specialists for technical SEO, content production and authority building. Smaller firms rarely have the capacity to cover all of it internally.
