Ranking Methodology
The 2026 best SEO expert ranking weighs five factors: live proof (the practice running real organic search wins in production, not just client case studies), full-stack scope (technical SEO plus content strategy plus link earning plus AI search optimization as one program), senior attention (the person you hire runs the work, not a placed junior), pricing fit for the customer band ($2M-$25M revenue differs from enterprise), and AI search literacy (2026 requires GEO and AEO competence). Each ranked option is best for a specific stage and structure - MarkCMO is not the universal answer, but for the $2M-$25M revenue growth-stage band it ranks first.
