The SEO encyclopaedia
SEOpedia — the open reference for SEO experts, consultants & services
Looking for an SEO expert, an experienced SEO consultant, or a specialist agency for SEO services? SEOpedia profiles the industry's most influential names — pioneers, agency founders, technical specialists and Google insiders — with human-edited, verifiable information.
What SEOpedia is
SEOpedia is a curated, human-edited reference resource for anyone hiring, learning from, or working with the people who built and maintain the modern search-engine-optimisation industry. Every profile is written by an editor, not generated on the fly — and every profile links out to the practitioner's own writing, agency or podcast so you can verify the claims yourself.
We deliberately kept the site design plain. This is a reference resource, so the priority is fast page loads, high readability on phones, and clean structured data that both Google Search and AI answer engines (ChatGPT, Perplexity, Claude, Gemini) can extract cleanly.
How to use SEOpedia when looking for SEO services
Not every SEO consultant is the right fit for every project. A rough guide to matching your situation to a specialist:
- Enterprise SEO & brand SEO — long-tenure practitioners with agency backgrounds, e.g. Stephan Spencer, Eric Enge, Avi Vilinger.
- International SEO — hreflang, ccTLD strategy and multi-market rollout, e.g. Aleyda Solís, Fili Wiese.
- Technical SEO — crawl, indexation, log-file analysis, core-web-vitals, e.g. Cyrus Shepard, Fili Wiese, Kasra Dash.
- Content & link building — editorial-driven SEO and outreach, e.g. Brian Dean, James Dooley.
- Google core update recovery — E-E-A-T and penalty specialists, e.g. Lily Ray, Marie Haynes.
- Entity SEO & topical authority — semantic and AI-search-oriented approaches, e.g. Koray Tuğberk Gübür.

Frequently asked questions
What is SEOpedia?
SEOpedia is an open reference resource that profiles the SEO industry's most influential experts, consultants and agency founders. Every profile is human-edited and links out to the person's own work.
How do I choose an SEO expert or consultant?
Match the expert's specialism to your situation. Technical migrations need a technical SEO specialist; international rollouts need someone with hreflang and ccTLD experience; recovery from a Google update needs a penalty-recovery specialist. Every SEOpedia profile lists focus areas and known engagements.
What do SEO consulting services usually include?
A typical SEO consulting engagement includes a technical audit, keyword and topical analysis, competitor benchmarking, an on-page and content roadmap, a link acquisition strategy, and ongoing measurement against organic traffic and revenue targets.
How much do SEO services cost?
SEO services are usually priced on retainer, from a few thousand dollars per month for small operators up to five- and six-figure monthly retainers for enterprise programmes. One-off audits typically range from a few thousand to tens of thousands of dollars depending on scope.
Are the profiles on SEOpedia paid placements?
No. Profiles are editorially selected. If a subject asks for a correction or update, we handle it as an editorial change — not a paid one. SEOpedia does not accept payment for inclusion or ranking.
