SEO Strategy Ltd is a premium SEO and AI optimisation consultancy led by Sean Mullins. It builds visibility systems that make businesses findable, citable and authoritative across traditional search, AI Overviews, ChatGPT, Perplexity and every surface where customers make decisions. The methodology is entity-first and covers the full visibility landscape rather than optimising for one channel at a time.

Is this right for you?
Best for
  • Businesses that have been in an execution relationship without genuine strategy
  • Founders or marketing directors who want to deal directly with the practitioner
  • Companies where AI citation and traditional rankings both matter commercially
  • Businesses with 6+ months of patience and a genuine commitment to compounding
Not for
  • Anyone who needs rapid results in weeks rather than months
  • Businesses wanting a large team with dedicated account management
  • Engagements requiring templated packages at low price points
What to expect: A direct relationship with Sean Mullins — no handoffs, no account managers. Strategy and execution from the same person who has been doing this since 2005. Compound visibility that grows over years, not a traffic spike that fades.

What’s the point of a pretty website if no one can find it? That question has driven this work since 2009. The answer in 2026 is more layered than it was — your customers find businesses through Google, ask ChatGPT for recommendations, see AI Overviews before they reach organic results, and use voice assistants that cite specific brands. But the underlying principle hasn’t shifted. Visibility only has value when it brings the right people — people who convert into enquiries, clients, and long-term relationships.

SEO Strategy Ltd builds visibility systems that make that happen. Sean Mullins leads every engagement. The methodology is rooted in 20+ years of hands-on SEO practice and evolved to cover the full landscape where your customers search, ask and decide.

Not Traditional SEO. Not Just AI SEO. Both.

Most agencies have to choose: either they’re traditional SEO specialists who don’t really understand AI visibility, or they’re AI-SEO newcomers with no depth in the fundamentals. SEO Strategy Ltd doesn’t have that problem.

The technical and content disciplines that have always driven organic rankings — site architecture, crawlability, topical authority, entity signals, structured data — are exactly the same disciplines that determine whether AI systems cite you. The landscape has evolved and fragmented. The foundations haven’t. Businesses that are visible across search and AI simultaneously are building on those same foundations, just more deliberately and with more surfaces in view.

Strong brands have always ranked. Now they rank, get cited, and dominate across every surface where their customers make decisions.

How This Works in Practice

Every engagement is led directly by Sean Mullins. That means the person who audits your site is the same person who builds the strategy, implements the technical fixes, writes the structured data, and monitors AI citation performance month to month. There is no account manager between you and the work. No handoff to a junior team six weeks in. No briefing a new contact from scratch every quarter.

That model isn’t a selling point — it’s a structural decision based on how results actually get produced. Translation loss happens when strategy and execution are separated. Momentum dies when the person who understood your business moves on. The consistent senior relationship is the mechanism, not a feature.

Where specialist execution is required — specific technical implementations, content at scale, sector-specific research — vetted resource is brought in and managed under the same consistent relationship. The quality standard and the accountability stay in one place.

What This Focuses On

Not the most impressive keyword volume. Not the longest technical fix list. The work that will produce the most meaningful visibility improvements for this business in this market — in the right order.

That means asking different questions to most agencies: which keywords are semantically close to your highest-converting queries? Which pages are cannibalising each other and suppressing authority that should be consolidated? Which AI platforms are citing your competitors for queries where you should appear, and what’s the specific gap? Which technical issues are actively costing rankings versus which are low-priority hygiene?

The focus is always on quality visibility — the kind that produces conversions, not just traffic numbers. It’s a lot easier to keep a client when the work is visibly producing results. The retention record reflects that: Olliers Solicitors since 2015, Motoring Defence Solicitors since 2018, Vivid Arts since 2012. Visibility systems compound. That’s what a multi-year relationship looks like when it’s working.

How This Differs From a Typical SEO Agency

Strategy and execution aren’t separated. At most agencies, the strategist and the implementer are different people, often different departments. Recommendations get diluted in translation. At SEO Strategy Ltd, the person who identified the opportunity is the person who acts on it.

The methodology is entity-first, not keyword-first. Keywords matter — they always will. But ranking for the right keywords in 2026 requires that AI systems, knowledge graphs and retrieval systems understand who you are, what you’re authoritative for, and why you’re trustworthy. Entity-first methodology builds the foundation that makes keyword work compound across both traditional search and AI platforms simultaneously.

The scope is the full visibility landscape. Search rankings. AI Overviews. ChatGPT citations. Perplexity recommendations. Voice search. AI agents. The businesses building presence across all of these now are the ones that will dominate when competitors eventually catch up. This is what online visibility systems means in practice.

Who This Is For

SEO Strategy Ltd works best for businesses in competitive B2B and professional services markets — law firms, healthcare IT, SaaS platforms, professional consultancies, premium brands — where visibility has a direct and measurable relationship to enquiries and conversions. Markets where a single retained client or won project justifies serious, sustained investment in getting found by the right people.

Geographically: we work across the UK and internationally, with deep roots in Hampshire and London.

Who This Probably Isn’t For

This isn’t the right fit if you’re looking for a low-cost monthly package with templated reporting. If you want social media management bundled alongside SEO. If you need a large team executing at volume across multiple channels simultaneously. Or if you’re expecting meaningful results within 4–6 weeks — genuine visibility improvements take longer to build and they’re worth it, but the timeline is real.

We’re selective about who we take on because every client gets direct senior attention, and that only works with the right clients on both sides.

Key Definitions

visibility system
An integrated approach to online discoverability covering traditional search rankings, AI platform citations, entity authority, and structured data — designed to compound over time rather than decay when a campaign ends
entity-first SEO
An SEO methodology that establishes a brand's machine-readable identity — structured data, Knowledge Graph presence, cross-platform consistency — as the foundation for keyword optimisation, producing results that serve both search engines and AI platforms simultaneously
AI citation
The appearance of a specific brand in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews or similar systems — distinct from organic rankings and requiring entity authority plus content extractability

Frequently Asked Questions

What makes SEO Strategy Ltd different from a traditional SEO agency?

Three structural differences. First, there's no separation between strategy and execution — Sean Mullins conducts the audit, builds the strategy, and implements the work. Second, the methodology covers the full visibility landscape: traditional search rankings, AI Overviews, ChatGPT and Perplexity citations, entity authority, and structured data — not just keywords and backlinks. Third, the focus is always on quality visibility that converts, not traffic volume for its own sake. The proof is in the retention record: clients stay for years because the work keeps producing results.

Is SEO Strategy Ltd an agency or a consultant?

Both, deliberately. It operates as a premium consultancy in terms of how engagements run — Sean Mullins leads every client relationship, there's no account manager layer, and strategic thinking is applied consistently. It operates as an agency in terms of execution capability — we build and implement, not just advise. Technical SEO, custom development, schema implementation, content architecture — built and deployed, not handed off as recommendations for someone else to act on.

What sectors do you specialise in?

Deepest expertise in law firms (criminal defence, motoring law, legal services), healthcare IT (managed file transfer, enterprise software), and SaaS and technology companies. Also work with professional services, premium e-commerce, and other sectors in competitive B2B markets where generic SEO isn't enough. The common thread is markets where the value per conversion is high enough that quality visibility — not just traffic volume — is the right goal.

Why does AI visibility matter alongside traditional SEO?

Because a significant and growing share of discovery now happens through AI systems. When someone asks ChatGPT to recommend a criminal defence solicitor, or asks Perplexity which SEO consultant to use, the AI doesn't return ten blue links — it names specific brands. Businesses with strong entity foundations and well-structured content get cited. Those optimised only for keyword rankings often don't appear at all. Both channels matter, and the right foundations serve both simultaneously.

What does "visibility systems" mean in practice?

Building the infrastructure that makes a business findable and citable across every surface where its customers make decisions — rather than optimising for one channel at a time. In practice: entity foundation (structured data, Knowledge Graph presence, cross-platform consistency), content architecture built for both human readers and AI extraction, technical SEO that serves crawlability and AI retrieval, and ongoing monitoring. The system compounds month on month rather than decaying when a campaign ends.

How long has SEO Strategy Ltd been operating?

Sean Mullins has been working in SEO since 2005. SEO Strategy Ltd formalised as a consultancy in 2020 after going full-time independent in 2014. Client relationships spanning a decade or more — Olliers Solicitors since 2015, Vivid Arts since 2012 — are the practical proof that the approach produces durable results through algorithm updates, platform changes, and the shift to AI-mediated discovery.

Do you work with businesses outside Hampshire?

Yes. Client work spans the UK and internationally. Hampshire and London are the deepest local markets, but sector expertise in law, SaaS and healthcare IT travels. If the visibility problem is complex enough to need specialist attention and the sector fits, geography isn't a limiting factor.

What does an engagement cost?

The day rate is £600–900 depending on engagement type. Standalone audits are typically 3–5 day engagements. Ongoing retainers start from 2–3 days per month. The initial 30-minute consultation is free. Every engagement is scoped and priced individually before work begins — no hidden costs, no surprise invoices.
