You know SEO is working for your law firm when three things move in the right direction together: qualified enquiries from organic search and Google Maps are increasing month over month, your firm appears for the practice-area and location queries that drive instructions, and your firm’s mentions and citations in AI assistants like ChatGPT and Perplexity are growing. Rankings alone aren’t enough. Traffic alone isn’t enough. The signal that matters is enquiries that turn into instructions.
This is the question most managing partners can’t answer with confidence — because their SEO agency reports the wrong things. Here’s how to read SEO performance like a senior partner reads a profit and loss statement.
The five metrics that actually tell you if SEO is working
1. Qualified enquiries from organic search
This is the metric that matters most. Not visits. Not impressions. Not rankings. Enquiries — specifically, enquiries that turn into matter conversations and instructions.
Most firms can’t tie this back accurately because their enquiry tracking is poor. The fix is straightforward: dedicated tracking phone numbers per source (Google organic, Google Ads, Google Maps), form submissions tagged by source, and a CRM that records the source of each enquiry through to instruction stage.
What good looks like: month-over-month growth in organic-source enquiries, and a steady or improving qualified-to-instruction conversion rate. A reasonable target for an established regional firm: 15–40 organic enquiries per month after 6–12 months of consistent work, converting at 20–40% to instructions.
2. Rankings on the queries that drive instructions
Rankings only matter for the right queries. A firm that ranks #1 for "solicitor regulations 2024" gains nothing if no prospect ever instructs from that query. The rankings that matter:
- Practice area + location combinations ("family solicitor [town]")
- Specific service queries ("contested probate solicitor London")
- Question-format queries ("how much does conveyancing cost in 2026")
- Branded queries (your firm’s name)
Don’t accept reports showing rankings on generic high-volume terms ("solicitor," "law firm," "legal advice") — those positions don’t drive enquiries.
3. Google Maps and local pack visibility
For most UK law firms, 50–70% of enquiries originate from the Google Maps local pack rather than the organic results below it. The metrics to track:
- Local pack position for high-intent queries ("[practice area] solicitor [town]")
- Direction requests on Google Business Profile (a proxy for serious intent)
- Call clicks on Google Business Profile
- Website visits from GBP
- Review volume and recency
- Profile views and search impressions
Google Business Profile Insights gives you all of this for free. A healthy GBP for a regional firm produces 40–150 direction requests and call clicks per month after 6 months of optimisation.
4. AI search citations and recommendations
This is the newest measure of SEO performance, and the firms that ignore it will lose ground over the next 18 months. The questions to answer:
- When prospects ask ChatGPT for a recommendation matching your firm’s profile, does your firm appear?
- How often are you mentioned across ChatGPT, Claude, Perplexity, Gemini and Grok for relevant queries?
- What sources cite you when AI engines source their answers?
- What sentiment do AI engines attach to your firm when mentioning you?
Specialist tools like keyword.com’s AI visibility tracker measure all of this. A healthy AI visibility profile for an established firm: cited by name for 20–40% of relevant prospect-style queries after 6–12 months of focused work.
5. Organic backlink growth from authoritative sources
Backlinks remain a foundational signal. The metric to track isn’t volume — it’s authority. One link from the Law Society Gazette is worth roughly 100 links from generic SEO directory sites.
The right report shows: total domain rating or domain authority (over time), number of referring domains from authoritative sources (top 1,000 UK sites), and specifically links from legal-relevant publications. An established UK law firm should be earning 2–6 authoritative new backlinks per quarter from genuinely consequential sources.
Reports your SEO consultant should be sending you
If your current monthly report doesn’t show the following, your consultant or agency is reporting on vanity metrics rather than commercial outcomes:
- Enquiries this month vs last month, by source
- Movement on the 20–30 priority queries that drive your specific practice and location mix
- Local pack performance for each office, per practice area
- Google Business Profile insights summary
- AI visibility tracking results (where available)
- What was shipped this month — specific pages updated, content published, technical fixes, citations built
- What’s planned for next month
- An honest commentary on what’s working and what isn’t
The reports should be readable by a managing partner in 15 minutes. If you need to be technical to understand them, the consultant has written them for themselves, not you.
The signs SEO is not working
Even with rising traffic, some firms quietly under-perform. The warning signs:
- Rankings improve but enquiries don’t (you’re ranking for the wrong queries)
- Traffic grows but conversion rate falls (you’re attracting unqualified visitors)
- Branded query rankings strong, non-branded weak (people who already know you find you, but new prospects don’t)
- Local pack rankings stagnant despite 6+ months of GBP work (likely citation inconsistency or competitor strength being underestimated)
- The work being done each month isn’t visible on your site (no new pages, no new content, no schema improvements you can see)
If any of these patterns appear for two consecutive quarters, it’s a sign to either pivot the strategy or change consultant.
The honest timeline
For a firm starting from a low baseline, realistic timelines look like:
- Months 1–3: Foundation work — GBP, technical SEO, practice area pages, citation cleanup. Limited visible change in enquiries.
- Months 3–6: First measurable lift in local pack visibility and Google Business Profile metrics. Early organic ranking improvements on lower-competition queries.
- Months 6–12: Material increase in qualified organic enquiries. Local pack rankings stabilise at strong positions. AI citation footprint begins.
- Months 12+: Compounding gains. Organic enquiries should be 2–3x baseline for firms that started low. AI citation profile measurable.
Firms that expect significant lift in the first 90 days are usually disappointed. Firms that judge after 12–18 months see the real picture.
Frequently asked questions
What’s the single most important SEO metric for a law firm?
Qualified enquiries from organic search and Google Maps, traced through to instruction stage. Everything else is leading-indicator data.
How can I tell if my SEO agency is doing real work?
Ask for a monthly list of specific deliverables shipped to your live website. Real SEO work is visible — new pages published, content updated, schema deployed, technical fixes made. If the only evidence is "we improved on-page SEO," you’re being charged for activity rather than output.
Should SEO performance be tied to bonus or fee structure?
Pure performance-only fees rarely work well for SRA-regulated firms because outcomes are influenced by factors outside the consultant’s control. A senior retainer with clear monthly deliverables and quarterly performance review is the model that fits best.
How does AI visibility tracking work?
Specialist tools query major AI engines (ChatGPT, Claude, Perplexity, Gemini, Grok) with prospect-style queries on a recurring schedule, then measure whether your firm appears in the answers, what sentiment is attached, and what sources are cited. Most law firms have never measured this.
If my rankings are stable but enquiries are falling, what’s wrong?
Usually one of: competitor improvement (others have moved up), reduced search demand in your area, or website conversion problems. The third is the most actionable — a CRO audit on your contact and practice-area pages often surfaces fixable issues.
