Top SEO Experts 2026

Founder & International SEO Consultant at Orainti. Madrid, Spain. International SEO, AI search optimization, technical SEO, ecommerce SEO.

Aleyda is the most diplomatic and open-minded person I have met in SEO. I included her not just because she is technically excellent, but because of what she has done for the community. SEOFOMO alone, the newsletter and the meetups, has connected thousands of SEOs who would never have found each other otherwise. She is always reachable, always willing to help, always open to anyone at any level. Someone once said “We don’t deserve Aleyda.” I think about that often. They are right.

Director at Candour. Norwich, United Kingdom. Technical SEO, People Also Ask research, content strategy, SEO training, Google security research.

Mark made one of the most important discoveries in SEO last year, around quality signals and how Google actually evaluates content. The research he put out around it was genuinely useful, the kind you read more than once. And then there are the drawings. If you follow him you know what I mean. He has a way of explaining complicated things through simple sketches that very few people can pull off. Big impact on the industry, and he makes it look easy.

Founder & Independent SEO Consultant at Trebole Ltd. London, United Kingdom. Technical SEO, SEO strategy, international SEO, ecommerce SEO, mentoring.

Silvia wrote a book on brand SEO: SEO for Branding: How to boost visibility and authority for personal and business brands. That alone would be enough. But she is also one of the nicest and most supportive people in the community. She gives a lot to the people around her, quietly and consistently. That matters.

Founder & SEO Consultant at Dergal Ltd. London, United Kingdom. Technical SEO, site migrations, analytics, enterprise SEO, growth.

Gerry might be the funniest SEO I know, but the humour always has a point. Behind it is a genuinely sharp mind and deep knowledge of SEO and digital marketing. He also has a big heart and more empathy than most people in this industry. That combination is rare, and it makes him someone worth knowing and following.

Founder at DeCabbit Consultancy. London, United Kingdom. SEO strategy, content strategy, link building, paid media, digital marketing training.

Judith is the best MC in the world. I am not being loose with that word. She can hold a room, manage speakers, handle anything unexpected, and make everyone feel like the event was always going to go exactly this way. She also knows more dark secrets about this industry than most. The impressive part is what she does with that knowledge: she uses it to help, not to harm. Event organizers love her for a reason.

Independent SEO, PPC & Analytics Consultant at OnlineMarkethink. Amsterdam, Netherlands. Technical SEO, conversion rate optimization, web performance, Google Analytics, PPC.

Arnout goes where most people do not bother to go. When the rest of the industry is focused on one signal, he is already three levels deeper, connecting dots nobody else noticed were there. He sees the full picture while everyone else is still arguing about one piece of it. That kind of thinking is rare.

Owner & Managing Director at Luminosity Digital. Dublin, Ireland. International SEO, generative search, digital strategy, SME marketing.

Aoife is technically excellent and has a skill not many people have: she can manage difficult clients without losing quality or patience. Working in international SEO with real enterprise clients is hard. Doing it calmly and well, consistently, is harder. She does both.

Senior SEO Consultant at Torque Partnership. Colchester, United Kingdom. Technical SEO, site migrations, SEO training, data-driven SEO, site architecture.

Chris is one of the best technical and enterprise SEOs I know. Large-scale migrations, crawl analysis, log-file work: he does it properly. Not the kind of consultant who writes a big report and disappears. The kind who makes sure it actually gets done.
