William Harvey

Senior SEO Consultant for Enterprise and International Websites

Independent SEO consulting from someone who has run organic search at S&P 500 scale and still does the technical work himself.

I help organisations work out why organic search is underperforming, what to fix first and how to get it delivered. Over 25 years I have led SEO for Iron Mountain across more than 60 country sites and 35 languages, run SEO and technical development at Staysure Group, and built and sold my own digital businesses.

Available now for consulting projects, audits and ongoing advisory, remote from the UK for UK and international clients.

01 / The job

What a senior SEO consultant should actually do for you.

Most SEO consulting produces a long audit, a list of 200 issues and no change on the site six months later. The audit is not the job. The job is a short list of the things that will move revenue, in the order they should be done, with enough technical detail that your developers can build them and enough commercial logic that your leadership will fund them.

That is what I deliver. I diagnose the problem properly, separate what matters from what merely scores badly in a tool, write recommendations your engineers can implement without a second translation, and stay involved until the work is live and measured.

I am also candid about what SEO cannot fix. If the problem is product, pricing or positioning, I will say so rather than sell you a content plan.

02 / Services

SEO consulting services.

01

Enterprise SEO audit and roadmap

A full diagnosis of why the site is not performing, and a prioritised roadmap your team can execute.

  • Technical, content and authority review across the whole estate
  • Branded and generic performance analysis, so you know what SEO is really contributing
  • Findings ranked by commercial impact and effort, not by tool score
  • A roadmap with owners, sequencing and expected outcomes
02

Technical SEO consulting

For large or complex sites where the platform itself is limiting visibility.

  • Crawl budget, indexation and site architecture
  • JavaScript rendering, faceted navigation and parameter handling
  • Core Web Vitals and site performance
  • Implementation specifications written for developers, not for marketers
03

Website migration consulting

Migrations are where most organic traffic is lost. I plan, govern and verify them so that does not happen to you.

  • Pre migration benchmarking and risk assessment
  • Redirect mapping, URL strategy and content parity checks
  • Launch day validation and post launch monitoring
  • Recovery plans when a migration has already gone wrong
04

International SEO consulting

For businesses selling across countries and languages, where structure and governance matter more than any single tactic.

  • Country and language site architecture
  • Hreflang and canonical governance, with validation tooling
  • Localisation quality and regional search engine requirements
  • Standards and playbooks for regional teams and agencies
05

AI search and answer engine visibility

A clear eyed assessment of where your brand appears in AI generated answers, what influences it and what is worth doing about it.

  • Ongoing tracking of citations, mentions and share of answer across Google AI Overviews, ChatGPT, Gemini and Perplexity
  • Measurement that connects AI search exposure to traffic, leads and revenue rather than reporting it as a vanity figure
  • Content, entity and structured data strategy for AI discoverability
  • Realistic guidance on vendors, tooling and how much to spend before the opportunity is proven
06

SEO data, measurement and reporting

Decisions that rest on joined up evidence rather than a tool's opinion.

  • GA4, Search Console, crawl and log file data brought into a single view
  • Branded and generic performance separated, with revenue influenced reporting where attribution allows
  • Automated reporting that reaches stakeholders on schedule without anyone compiling a deck
  • Forecasting and scenario modelling for investment cases
07

Monitoring, early detection and prevention

Most organic losses are preventable. They come from a template change nobody flagged, a noindex that slipped into a release or a redirect that quietly broke. I build the systems that catch these before they cost revenue.

  • Continuous sitewide monitoring for broken links, canonicals, noindex, 404s and redirect chains
  • Uptime, indexation and ranking movement alerts that notify the right stakeholders automatically
  • Pre publish checks for content teams and hreflang validation at page and site level
  • Release and migration guardrails, so SEO regressions are caught in testing rather than in Search Console weeks later
08

Automation and specialist AI tooling

Where off the shelf tools stop, I build what is needed.

  • Python automation for repetitive technical, data and reporting work
  • Semantic topic mapping and internal linking recommendations built on embeddings and graph analysis, joined to GA4 and Search Console data
  • Specialist AI models trained for defined SEO and content intelligence tasks
  • Honest advice on which tools to buy and which to build
03 / How I work

Diagnose, prioritise, specify, ship.

01

Diagnose first.

Every engagement starts with understanding the commercial problem, not the SEO symptoms. I look at the data, the platform, the team and the constraints before recommending anything.

02

Prioritise ruthlessly.

You get a short list of what will move the numbers, in order, with the reasoning. The long list exists, but it does not drive the plan.

03

Write for the people who build it.

Recommendations arrive as specifications your developers can pick up, with acceptance criteria, not as slides that need translating.

04

Stay until it ships.

I remain involved through delivery, work in your Jira or equivalent if that helps, and measure the outcome against the baseline we agreed.

04 / Experience

Experience behind the advice.

I led global SEO at Iron Mountain, an S&P 500 company, across more than 60 country websites and 35 languages, and was named its Global Marketing Star of the Year in 2025. Before that I ran SEO and technical development at Staysure Group.

I co founded RichWeb Media and founded BroadbandExpert.com and MyOnlineEstateAgent.com, operating in the UK and US, and sold two of them. Running businesses that lived or died on organic search is a different education from advising on it.

I have spent 15 years as a hands on developer alongside my SEO work and have built monitoring, validation and early warning tooling at every organisation I have joined. Over the past three years I have trained more than 50 specialist AI models and now build semantic topic and internal linking systems joined to GA4 and Search Console data.

Google has invited me to its Gold level Search Product Expert programme in recognition of contributions to the Search community.

05 / Who this suits

I am most useful to.

  • Enterprise and mid market businesses whose organic performance has plateaued or declined and who want an independent diagnosis
  • Marketing and digital leaders who need a second opinion on an agency's recommendations or a proposed technical investment
  • Product and Engineering teams planning a migration, replatform or redesign
  • International businesses with visibility problems in specific markets or languages
  • In house SEO teams who need senior technical depth on a specific problem without a permanent hire
  • Agencies needing enterprise or technical expertise on a client engagement
  • Businesses that have lost traffic to a release or migration and want it recovered, and the next one prevented
06 / Questions

SEO consultant FAQs.

What does an SEO consultant actually do?

An SEO consultant works out why a website is not earning the organic search traffic and revenue it should, and tells you what to change, in what order, to fix it. A good one diagnoses the problem across technical, content and authority, prioritises by commercial impact, writes recommendations your developers and content team can act on, and stays involved until the changes are live and measured. A weak one hands over a long audit and leaves.

How much does an SEO consultant cost in the UK?

Day rates for experienced UK SEO consultants typically run from several hundred pounds to well over a thousand, depending on seniority and the complexity of the site. Enterprise and international work sits at the upper end because the cost of getting it wrong is higher. I price by project or by a monthly retainer, agreed up front after a short scoping conversation, so you know the cost before you commit. The cheaper question to ask is what a wrong decision on a migration or platform change would cost you.

Should I hire an SEO consultant or an SEO agency?

Hire a consultant when you need senior judgement on a specific problem: a diagnosis, a migration, a technical or international issue, or a second opinion on what you are being told. Hire an agency when you need ongoing volume of execution, such as content production or link building, and have someone to direct it. Many organisations use both, with the consultant setting direction and checking the agency's work. What you should avoid is paying agency retainers for strategy nobody senior is actually providing.

How do I choose a good SEO consultant?

Ask what they have run, not what they have audited. Look for experience leading SEO inside a business of your scale, hands on technical ability rather than reliance on tool reports, and a willingness to tell you what will not work. Ask how they prioritise and how recommendations reach your developers. Ask for a reference from an engineering stakeholder as well as a marketing one. Be wary of guaranteed rankings, fixed monthly packages and anyone who cannot explain their advice in plain English.

What is an enterprise SEO consultant and how is that different?

An enterprise SEO consultant works on large sites, often tens of thousands of pages or more, across multiple teams, markets and platforms, where the main constraints are architecture, governance and getting changes through Product and Engineering. The SEO fundamentals are the same as for any site. What differs is scale, risk and organisation: a template change can affect a million URLs, and the hard part is usually securing the engineering capacity rather than knowing what to do. My experience is at this scale, including more than 60 country sites at Iron Mountain.

What does a technical SEO consultant do?

A technical SEO consultant identifies and fixes the problems in a website's platform, code and architecture that stop search engines crawling, indexing and ranking its pages. That covers crawl budget, indexation, site structure, JavaScript rendering, redirects, canonicals, hreflang, Core Web Vitals and structured data. The output should be implementation specifications your developers can build from, with acceptance criteria, and monitoring so the fixes stay fixed after the next release.

How do I migrate a website without losing SEO traffic?

Benchmark before you start, map every URL that earns traffic or links to its destination, keep content parity, test redirects and indexation signals in staging, validate on launch day and monitor closely for the weeks after. Most traffic losses in migrations come from missed redirects, changed templates, lost internal links or an accidental noindex, and all of them are preventable with the right governance. I plan and oversee migrations for this reason, and I also recover ones that have already gone wrong.

When do I need an international SEO consultant?

When you sell in more than one country or language and your visibility varies between markets in ways you cannot explain. The usual causes are site architecture, hreflang and canonical errors, poor localisation or regional teams working to different standards. An international SEO consultant sets the structure and governance so every market is served correctly, and builds the validation to keep it that way. I led SEO across 35 languages at Iron Mountain and have built hreflang validation tooling for estates of that size.

How do I get my business to appear in ChatGPT, Google AI Overviews and other AI search results?

AI search engines draw on the same signals as organic search, with extra weight on clear, well structured content that answers specific questions, consistent information about your brand across the web, and citations from sources those engines trust. The first step is measuring where you appear now and for which questions. Then it is a matter of content, entity and structured data work folded into your organic roadmap. I advise on this as part of SEO consulting rather than as a separate discipline, because treating it separately usually leads to overspending.

How long does SEO take to show results?

Technical fixes can show within weeks of going live. Content and authority work usually takes three to six months to compound, and competitive terms longer. The honest variable is not search engines but your own delivery: a recommendation that waits four months for engineering time will show results four months later than one that ships. I set a measurement baseline at the start and report against it so progress is visible and the delays are attributed correctly.

Can you guarantee first page rankings?

No, and you should treat any consultant who says yes with suspicion. Rankings depend on competitors, search engine changes and how well your organisation delivers, none of which a consultant controls. What I can commit to is a correct diagnosis, recommendations prioritised by commercial value, specifications your team can build, and honest reporting on what moved and why. That is what produces results, and it is what you can hold me to.

What is included in an SEO audit?

A proper SEO audit covers technical health, content quality and coverage, authority and links, and how the site performs against competitors, with findings ranked by commercial impact rather than by how many issues a tool found. It should end in a prioritised roadmap with owners and sequencing. Mine also separates branded from generic performance so you can see what SEO is really contributing, and includes a session to walk your Product and Engineering leads through what needs building and why.
