You have one SEO proposal on your desk. Maybe three. Each one is professionally formatted. Each one mentions audits, content, links, and reporting. Each one runs to twelve or fifteen pages. And none of them gives you a way to tell whether the scope is adequate, or whether you are about to commit £20,000 to twelve weeks of activity that produces nothing you can defend in a partners’ meeting.
Most SEO proposals aimed at UK law firms look broadly similar from across a desk. The difference between a serious 90-day pilot and a vague one is rarely the document length, the agency’s reputation, or the price quoted on the back page. It is the specificity of the named deliverables, the explicitness of the success criteria, and the cadence of the reporting. Once you know what to look for, the gap between a credible proposal and a hopeful one is visible at a glance. This article gives you that framework.
It explains what a 90-day SEO pilot for a UK law firm should contain, week by week, with named deliverables and defined success criteria. It shows you the language a serious proposal uses, contrasted with the language a vague one uses. It addresses the AI search dimension that did not exist in the 2024 pilot conversation, and it gives you an honest UK pricing range so the numbers on the proposal are not a mystery. You are not expected to become an SEO specialist. You are expected to make a sound procurement decision, and this article gives you the tools to do that.
The visibility landscape has shifted in 2026. AI Overviews, AI Mode, and large language model answer engines (ChatGPT, Perplexity, Claude, and Gemini at time of writing) now intercept a meaningful share of legal queries before any click reaches your firm’s site, and a credible pilot should reflect this. Before going into the detail of what a serious pilot includes, define what one is — and what it isn’t.
Key takeaways
- A 90-day SEO pilot should have three named phases: audit and strategy (Weeks 1–4), execution (Weeks 5–8), and measurement and recommendation (Weeks 9–12).
- Every phase should list named deliverables with expected completion dates, not service descriptions like “content creation” or “link building”.
- Defined success criteria at 30, 60, and 90 days should be agreed before the engagement starts, not constructed retrospectively.
- A serious pilot includes weekly progress visibility and a formal mid-pilot review meeting, not just a monthly report.
- The pilot should end with a clear go/no-go recommendation supported by data, not an automatic renewal clause.

1. What is a 90-day SEO pilot, and what isn’t it?
A 90-day SEO pilot is a structured, time-bound engagement designed to establish, in three months, whether SEO can work for your firm in your market and from your current starting position. It is not a guarantee of page-one rankings in 90 days, and any proposal that promises one should be rejected on that basis alone.
A credible pilot delivers three things. The first is a clear picture of the firm’s current position and competitive landscape, established in the opening weeks. The second is measurable technical and content improvements implemented during the engagement, so the firm has something concrete to show for the spend. The third is enough data at the 90-day mark (indexed pages, organic impressions, long-tail keyword movement, attribution setup) to make an informed go/no-go decision on what to do next.
The pilot sits between two engagement types your firm may have seen before. A one-off audit is diagnostic only: it identifies problems but does not begin solving them, and at the end you have a report rather than progress. A full retainer is open-ended: it assumes the strategy is already validated, and partnership approval committees usually find it harder to sign off as a first engagement. The pilot diagnoses and treats, with a built-in decision point at Day 90. This structure is one of the reasons pilots have become the default first engagement for UK law firms over the last two years — partnership approval cycles favour fixed-scope, time-bound work with a defined endpoint over open-ended commitments.
Legal queries fall into Google’s YMYL category (your money or your life — Google’s category for queries where the stakes for the user are high). The scrutiny Google applies to law firm content is unusually strict because of this, and a pilot’s content work has to clear a higher bar than equivalent work in many other sectors. Any proposal that treats law firm SEO as a generic service offering, without engaging with this, is missing the central context. For a deeper picture of practice-area timelines and what realistic 90-day signals look like, the 2026 timelines article walks through honest expectations by practice area.
2. What does a credible pilot proposal include, at the top level?
A credible pilot proposal contains five elements: a defined scope tied to your firm’s specifics, named deliverables with expected completion dates, explicit success criteria at 30, 60, and 90 days, a reporting cadence with mid-pilot review, and a formal 90-day review with a go/no-go recommendation. If any one of these is missing, the gap is not a minor formatting issue — it is a specific way the agency has chosen not to be accountable for that dimension of the work.
Before turning to the phase-by-phase detail, this five-element checklist is the test you can apply to any proposal on your desk in five minutes.
| Element | What it is | Why it matters | Red flag if missing |
|---|---|---|---|
| Defined scope | A description of which practice areas, locations, and visibility channels (organic, local, AI search) the pilot will address | A scope that fits any firm in any sector tells you the agency has not engaged with your specifics | The proposal could apply to any law firm in any city, with no named practice areas or locations |
| Named deliverables by phase | A list of specific outputs by week or phase: “technical audit report by Week 2”, “four practice-area pages refreshed by Week 8” — not “content creation” | Named deliverables are the only basis for tracking progress; activity descriptions cannot be held to a timetable | Outputs described in general terms with no expected completion date |
| Explicit success criteria at 30, 60, and 90 days | Defined milestones — what “on track” looks like at each checkpoint, agreed before the engagement starts | Without milestones, the firm has no basis for raising concerns at Day 45 or Day 60; disputes only surface at Day 90, when it is too late | No milestones, or milestones described only as “improved rankings” without specifying what for |
| A reporting cadence and format | Weekly progress updates, a monthly report, and a mid-pilot review meeting — with the content of each defined | The cadence is what makes problems visible early enough to fix; a once-a-month PDF is not a cadence | “Monthly reporting included” with no detail on metrics, format, or review meetings |
| A 90-day review with a go/no-go recommendation | A formal evaluation point at Day 90, with a written recommendation: continue, adjust scope, or pause — supported by the pilot’s data | Without a formal review, continuation defaults to renewal regardless of outcome | The proposal assumes continuation without a formal review point, or describes the 90-day mark as the start of “ongoing optimisation” |
The contrast that matters is not document length. A tighter proposal can be more credible than a longer one. The test is whether each deliverable answers four questions: what exactly, by when, measured how, and reviewed in what setting. Where the proposal cannot answer those questions, the gap is the red flag.
One more pattern is worth noting: a credible proposal explains what is not in scope as well as what is. Silence on scope boundaries is a slow problem. The firm and the agency reach Day 60 with different assumptions about what should have been delivered, and the resulting conversation rarely goes well for either side.
3. What should each phase of the pilot deliver, week by week?
A credible 90-day pilot breaks into three named phases. Phase 1 is audit and strategy. Phase 2 is execution. Phase 3 is measurement, calibration, and recommendation. The detail below sets out what each phase should contain at the level of named deliverables, so you can lay any proposal over it and see what is missing.
Phase 1 — Audit, strategy, and foundation (Weeks 1–4)
The first month is diagnostic and strategic. No new content should be published and no links built until this phase is complete. The strategy informs the work; the work does not begin without the strategy.
- Technical SEO audit. Crawl health, indexation status, site speed, mobile usability, schema coverage, and Core Web Vitals (Google’s measure of how a page feels to the user — loading, interactivity, and visual stability). Delivered as a written report with prioritised actions. Around half of all sites currently fail Google’s “good” thresholds on at least one Core Web Vital, with mobile failure rates running meaningfully higher than desktop, so a real audit usually surfaces remediation work.
- Competitive landscape analysis. Identify the top five to ten organic competitors for the firm’s priority practice areas and locations. Assess domain authority (a third-party score estimating a site’s competitive strength), content depth, backlink profile, and keyword positions. Note where the competitive set in AI Overviews differs from the competitive set in standard organic results — this often matters more than the agency is willing to admit upfront.
- Keyword and content mapping. Map target keywords to existing pages on the firm’s site. Identify gaps where new content is needed. Prioritise by commercial value (which practice areas bring in the most revenue?) and by competitive difficulty. A proper mapping exercise looks at topical depth across the firm’s practice areas, not just keyword volume.
- Content strategy and calendar. A documented plan for what content will be created, refreshed, consolidated, or retired in Phases 2 and 3. Include target keywords, intended page types, and publication schedule. For firms with a long-running news or insights section, the strategy should also address the hidden SEO risks in law firm news sections, because content debt in the older archive often suppresses the pages the pilot is trying to lift.
- Baseline measurement. Set up or verify Google Search Console, Google Analytics 4, rank tracking, and call or form attribution. Record baseline metrics: indexed pages, organic impressions, keyword positions, and enquiry volume. Without baselines, none of the 90-day results are measurable. The Phase 1 audit should also assess crawl efficiency through Google Search Console, because crawl signals frequently predict which pages will respond to the Phase 2 work.
- Onboarding and access. CMS access, analytics access, brand guidelines, approval workflows. This administrative work must complete in Week 1 to avoid downstream delays — every day of access friction is a day taken from execution time.
Phase 2 — Execution and implementation (Weeks 5–8)
The strategy from Phase 1 is now being executed. Activity should be visible and measurable.
- Technical fixes implemented. Prioritised actions from the audit are in progress or complete. Crawl issues resolved, schema deployed, with improvements made to speed and INP (Interaction to Next Paint, the metric that replaced First Input Delay in March 2024). Each action should appear in the weekly update with a status of done, in progress, or blocked.
- Content production begins. The first new or refreshed pieces are published. These should target keywords mapped in Phase 1 and be structured for both organic search and AI discoverability (answer-first paragraphs, question-format headers, clear schema, named human review), alongside matching content to commercial-intent queries so the new pages actually convert visitors. A serious pilot publishes three to six pieces of meaningful content in this phase, not one token blog post. UK law firm publicity must be accurate and not misleading under SRA Rule 8.8, so content produced on the firm’s behalf has to clear that bar before it goes live.
- On-page optimisation of existing priority pages. Practice-area pages, location pages, and solicitor profiles are reviewed and improved: meta titles, descriptions, heading structure, internal linking to and from the page. This is often where the fastest gains appear, because the pages are already indexed and ranking somewhere — moving them up is structurally easier than building new authority from scratch.
- Local SEO foundations. Google Business Profile optimised, citation audit completed, review-collection process initiated if not already in place. For most UK firms this is foundational work that should already have been done, but rarely has.
- Authority and digital PR groundwork. Initial outreach for digital PR, content partnerships, or trade-press placements. No placements expected yet, but activity should be documented and underway. Backlink results typically lag Phase 2 by months — but the groundwork has to be done in Phase 2 for results to land in Months 4 to 6.
- Mid-pilot review meeting (Week 6 or 8). A formal review with the client. Status of every Phase 1 deliverable. Status of every Phase 2 deliverable. Any adjustments to the Phase 3 plan. This is not optional in a serious pilot. It is the accountability mechanism that makes the rest of the engagement trustworthy.
Phase 3 — Measurement, calibration, and recommendation (Weeks 9–12)
The final month is about measuring early signals, calibrating the strategy, and building the case for continuation or stopping.
- Continued execution. Work does not stop in the measurement phase. Content production and technical improvements continue alongside analysis.
- Early-signal measurement against baseline. Indexed pages, organic impressions, keyword positions (especially long-tail — high-volume head terms rarely move in 90 days, but long-tail keyword movement is realistic), organic traffic trends, crawl health improvements. Compared like-for-like against the Phase 1 baseline.
- Attribution check. Confirm that organic enquiries can be tracked back to the work. Call tracking, form attribution, UTM parameters on internal links. Without attribution, the pilot’s outcome is invisible to the firm — which means it cannot be defended at partnership level, regardless of how good the underlying work was.
- The 90-day report. A written document covering what was done, what changed, what the data shows, and a clear recommendation: continue, adjust scope, or pause. Include projected timelines for the next six to twelve months if the data supports continuation. The report should be written so a managing partner who has not been in any meeting can read it cold and reach the same conclusion the agency is recommending.
- Go/no-go decision framework. The report should give the firm enough data to make an informed decision. Not “trust us, it is working” — but here is the evidence, here is what it means, here is our recommendation, and here is what we suggest as next steps if you decide to continue.
Want a pilot scoped to this standard for your firm?
Crescat’s 90-day pilot planning call is a free, no-obligation 60-minute conversation that gives you a draft scope document for your firm: named deliverables, week-level milestones, and defined success criteria at 30, 60, and 90 days. You leave with a framework you can lay over any proposal on your desk, including ours. You speak to a member of our senior team.
4. How do you spot an under-scoped proposal at a glance?
The single most reliable signal that a proposal will underdeliver is the absence of specificity in its written scope. Agencies that lack specificity either do not have a process to deliver against, or do not want to be held to one. Neither is acceptable when a UK law firm is committing meaningful budget.
The table below contrasts the language a weak proposal uses with the language a serious proposal uses, across the five most common deliverable categories. The contrast is the asset. Read the left column as a list of phrases you should send back for revision.
| What a weak proposal says | What a serious proposal says |
|---|---|
| “We’ll conduct an SEO audit” | “We’ll deliver a technical audit covering crawl health, indexation, speed, schema, Core Web Vitals, and mobile usability, with a prioritised action plan, by end of Week 2” |
| “We’ll create content for your blog” | “We’ll publish four practice-area pages and two supporting articles targeting [specific keyword clusters], structured for organic search and AI discoverability, with named human review, by end of Week 8” |
| “Monthly reporting included” | “Weekly progress updates by email; formal monthly report covering indexed pages, impressions, keyword positions, and organic enquiries; mid-pilot review meeting at Week 6 or 8” |
| “SEO takes time — expect results in six to twelve months” | “At 90 days you should see: technical issues resolved, new content indexed, long-tail keyword movement, and measurable organic impression growth. Here are the specific benchmarks for your firm” |
| “Our contract renews automatically” | “The pilot ends with a formal 90-day review and go/no-go recommendation. Continuation is a mutual decision based on the data the pilot produces” |
A second pattern is worth flagging because it is harder to spot. A credible proposal explains what is not in scope as well as what is. Most weak proposals are silent on scope boundaries — and silence on scope is a slow problem. By Day 60 the firm assumes “content production” includes location pages; the agency assumes it does not. Neither side raises it earlier because both assumed the other had read the same scope into the same paragraph. The conversation that follows is rarely a good one.
The other tell, less visible from the proposal document itself, is the absence of any reference to AI search visibility. A 2026 pilot scope that addresses only organic ranking is missing a channel that legal buyers now use routinely — sometimes before they ever click through to a firm’s site. Section 5 covers what AI search visibility should look like inside a pilot.
5. How should the pilot handle AI search visibility?
AI search visibility is no longer an optional add-on to a 90-day pilot. The behaviour has shifted fast: AI Overview citations have moved away from the top ten organic results, with only 37.9% overlap in March 2026, down from 76% the previous July, per Ahrefs’ analysis of its global keyword corpus. Ranking well organically is no longer a sufficient proxy for being named in AI-generated answers. The Crescat series article on how AI search decides which firms to surface covers the underlying signals (entities, schema, content structure, and authority) in detail.
A credible pilot proposal should include AI search visibility work as a named deliverable across all three phases. In Phase 1, that means a baseline audit of how the firm currently appears (or does not) across three to five priority practice + location queries in Google AI Overviews, Google AI Mode, and at least one large language model answer engine (typically ChatGPT or Perplexity). In Phase 2, it means specific actions to improve extractability: answer-first paragraph structure on priority pages, question-format headers where the underlying query supports it, schema markup that signals the firm’s expertise areas, and content depth on the practice areas the firm actually wants to be cited for. In Phase 3, it means re-measuring against the same baseline queries and reporting the change.
The umbrella term to use in body copy is AI visibility — the firm’s presence in AI-generated answers across Google AI Overviews, AI Mode, and large language model answer engines such as ChatGPT, Perplexity, Claude, and Gemini at time of writing. In the United States, Pew Research Center’s 2025 study (data captured March 2025, published 22 July 2025) found that users who saw an AI summary clicked through to a website 8% of the time, compared with 15% for users who did not see an AI summary. The click-rate gap is one supporting reason to take this seriously now rather than waiting for AI search to “obviously” matter to your firm’s enquiry volume — by the time it does, your competitors will have spent a year building the visibility you do not yet have.
A pilot that does not include this work is incomplete. A pilot that includes it but cannot tell you what success looks like at Day 90 in concrete terms is incomplete in a different way.
6. How much should a 90-day pilot cost, and what makes the pricing range realistic?
The UK market range for a properly scoped 90-day SEO pilot for a law firm with two to three priority practice areas sits between approximately £2,500 and £15,000+ per month, depending on practice area competitiveness, geographic scope, technical complexity of the existing site, content production volume, and authority-building investment. Figures are indicative — drawn from aggregated UK SEO retainer market research rather than a single primary source.
The table below sets out the three typical bands inside that range.
| Price band | Firm profile | Typical scope |
|---|---|---|
| £2,500–£3,000 per month | Regional firm, single office | Narrow scope, limited content production, focused remediation rather than wide-ranging work |
| £3,000–£6,000 per month | Mid-market UK firm | Two to three priority practice areas, full Phase 1–3 scope, modest digital PR |
| £6,000–£15,000+ per month | National or multi-office firm | Broader practice-area scope, meaningful content production volume, sustained authority-building investment |
Two boundary observations are worth making. First, ranges below £2,000 per month rarely deliver a credible pilot. The minimum staffing required to deliver Phase 1’s audit work, Phase 2’s execution, and Phase 3’s measurement is structurally incompatible with budgets at that level. A proposal below this floor is likely either under-resourced or quietly assuming the firm will accept reduced scope without being told. Second, ranges above £15,000 per month require more scrutiny, not less. Higher prices do not automatically signal better delivery. The same five-element test applies. A £25,000-per-month proposal with vague deliverables is a worse procurement risk than a £6,000-per-month proposal with named outputs.
Pricing structures to be wary of are also worth naming. Performance-based pricing tied to ranking promises is a red flag — credible agencies do not promise rankings because no agency can guarantee specific rankings. Pricing based on “leads delivered” can be a fair model in some sectors but is structurally difficult in legal SEO, because legal enquiry quality varies enormously and is not always controllable by the agency that produced the content the enquirer found.
7. Common questions about a 90-day SEO pilot for UK law firms
Can a 90-day pilot deliver page-one rankings for competitive legal terms?
No, and any proposal that promises this should be rejected on that basis alone. Competitive legal head terms (“personal injury solicitor London”, “commercial property solicitor Manchester”) take six to eighteen months of sustained work in most cases. What a 90-day pilot can deliver is technical groundwork, content production, indexed-page growth, long-tail keyword movement, and the data foundation to forecast realistic timelines for the harder terms.
Should I pause PPC during the SEO pilot?
Generally, no. SEO and PPC measure different things and serve different purposes during a pilot. PPC gives short-term enquiry continuity while the SEO work compounds. Many firms reduce or rebalance PPC at Day 90 once the SEO data supports a clearer channel-mix decision, but pausing during the pilot itself removes the comparison baseline against which the SEO work is judged.
What level of access does the agency need from the firm?
CMS access (or the ability to publish through a defined workflow), Google Search Console access, Google Analytics 4 access, brand guidelines, an agreed primary point of contact at the firm, and an approval workflow for new content. The administrative work usually takes a week, and front-loading it in Week 1 avoids a category of delay that otherwise repeats every time a deliverable needs sign-off.
What happens at the end of the 90 days?
The pilot ends with a written 90-day report, a go/no-go recommendation, and — if continuation is agreed — a proposed scope for Months 4 to 12. Continuation is a mutual decision based on the data the pilot has produced, not an automatic contractual default. A pilot designed properly makes the continuation decision easy because the evidence base is already in place.
What does a “no-go” outcome at Day 90 actually look like?
A no-go outcome is genuinely useful to the firm. The data shows where the pilot did and did not move signals, where the structural blockers sit (site architecture, content debt, partnership approval friction), and what would need to change before any future investment in SEO is worth making. A pilot that ends in a measured “not yet, and here’s why” is more valuable than a year-long retainer that ends in ambiguity about why nothing seems to have happened.
8. Where to start
A serious 90-day SEO pilot is not a marketing flourish or a contract length. It is a structural choice that gives the firm decision-quality information before committing to a longer engagement. The framework in this article (the five-element checklist, the phase-by-phase deliverables across twelve weeks, the red flags table, the AI search visibility section, the pricing range) is the standard against which any proposal on your desk should be judged.
Every deliverable in a credible proposal answers four questions: what exactly, by when, measured how, and reviewed in what setting. Where the proposal cannot answer those questions for any one of the five elements in Section 2, the gap is the red flag. Send it back for revision before signing.
The firms that handle this well treat the pilot as a structured procurement exercise rather than as a leap of faith. You would not instruct a solicitor without understanding the scope of work. There is no reason to instruct an SEO agency on a less rigorous basis.
