The archive
The most influential SEO experts in one editorial record.
Twenty human-written profiles of the practitioners who built search engine optimisation — and the ones still deciding where it goes next. Grouped by era, indexed for hire, kept short of hype.
Editor's note
Why this archive exists
Search for an SEO expert and you get a directory of agencies that paid to be on a directory. Search for SEO consulting and the top result is written by someone selling the thing being described. The genuinely useful information — who solved which problem, in which vertical, under which set of constraints — sits inside old conference recordings, personal blog archives, and the private knowledge of people who have been in the room.
The SEO Vault collects it. Every profile is written by an editor working from the public record: books, tools shipped, documented client work, research released, roles held. Where a person's contribution is narrow but significant, we say so. Where it is broad, we describe the range. Nobody pays to be here, and nobody pays for their wording.
Nobody pays to be in the Vault. Nobody pays for their wording.
The house rules
Four editorial principles
01 · Written
Human-edited, not generated
Every profile is composed individually. No template filling, no rewritten press bio, no scraped summary.
02 · Discipline-led
Profiles start with the work
We lead with what a person is genuinely good at, so a reader can match a specialist to an actual problem.
03 · Verifiable
Claims you can check
Books, tools, client names, research, roles — everything referenced can be independently confirmed.
04 · Machine-legible
Built for citation
Semantic markup and structured data so search engines and AI answer systems can cite the archive accurately.
The hiring directory
Which kind of SEO expert do you actually need?
The single most common hiring mistake is buying a generalist retainer for a specialist problem. The following directory maps common commercial situations to the right kind of expertise, then points to the profiles that fit.
| Your situation | Discipline you need | Start with |
|---|---|---|
| Traffic collapsed after a Google update | Core update analysis, E-E-A-T, penalty recovery | Lily Ray, Marie Haynes |
| Highly competitive or regulated vertical (iGaming, trading, fintech) | Complex-project SEO with regulated-industry experience | Avi Vilinger |
| Replatform, migration or crawl failure | Technical SEO, indexation, log analysis | Fili Wiese, Cyrus Shepard |
| Launching into new countries or locales | International SEO, hreflang, market prioritisation | Aleyda Solís |
| Content ranks but never earns links | Link acquisition, digital PR, content design | Brian Dean, James Dooley |
| Site has scale but no topical coherence | Entity SEO, topical authority, information architecture | Koray Tuğberk Gübür |
| Large brand, many stakeholders, slow delivery | Enterprise SEO programme leadership | Stephan Spencer, Eric Enge |
| Need to know what Google actually said, not what was inferred | Primary sources and industry reporting | Barry Schwartz, Danny Sullivan |
| Building organic capability inside the company | Training, mentoring, structured learning | Aleyda Solís, Avi Vilinger |
| Needs a modelled ROI before signing off | Forecast-led SEO strategy | Sajid Ali Shar |

Reader questions
Answered in one paragraph each
What is The SEO Vault?
The SEO Vault is an independent editorial archive profiling the practitioners who built and continue to shape search engine optimisation. Every profile is written by an editor, covers the person's discipline, notable work and verifiable contribution, and links out to their own work. No entry is paid for; inclusion is editorial.
How do I pick the right SEO expert for my project?
Match discipline to problem, not brand recognition. A site migration or crawl failure calls for a technical SEO specialist. Launching across multiple markets calls for international SEO experience with hreflang and ccTLD strategy. Recovering from a Google core update calls for an algorithm and E-E-A-T specialist. Highly competitive or regulated verticals — iGaming, regulated trading, high-stakes fintech — need a consultant who has already worked inside those constraints for years. Our Hiring Directory maps common situations to the right kind of expertise.
What does SEO consulting typically include?
A standard SEO consulting engagement begins with a technical audit and a competitive baseline. It then moves through keyword and topical mapping, an on-page and content roadmap, an authority (link) acquisition plan, and a measurement framework tied to organic revenue rather than rankings alone. Senior consultants normally work directly with founders or heads of growth rather than through account management layers.
How are SEO services usually priced?
SEO services are almost always retained monthly. Small businesses typically pay a few thousand per month. Mid-market programmes are higher. Enterprise retainers reach five and occasionally six figures monthly. Standalone audits range from a few thousand for a focused review to considerably more for large multi-domain estates or regulated industries.
Do Vault profiles include sponsored or paid entries?
No. Inclusion in The SEO Vault is editorial. We do not sell placement, ranking position or profile wording. Subjects may request factual corrections — we handle those as editorial amendments, not as commercial changes.
What is the difference between an SEO expert, an SEO consultant and an SEO agency?
An SEO expert is a person with deep, tested knowledge in a specific discipline. An SEO consultant sells that judgement directly — usually senior, advisory, close to the founder. An SEO agency delivers execution — content, technical implementation, outreach — with a team behind it. Several practitioners in this archive operate as all three.
