How We Evaluated AI SEO Firms in 2025

Our evaluation blends practitioner experience with publicly available information, cross-referencing multiple industry lists and editorial roundups, service pages, and known thought leadership. We emphasized criteria that drive outcomes in AI search: technical readiness, integration with generative engines, and measurable, transparent reporting. We also considered enterprise capability, speed of iteration, and advisory depth.

• Team quality and specialization in AEO, GEO, LLM optimization, and entity SEO
• Service comprehensiveness and cross-channel integration
• Demonstrated results and transparent, methodical reporting
• Client alignment, communication, and retention signals

Why a structured approach matters: an industry virtual training from the American Marketing Association introduced a clear rubric for vetting AI SEO partners and reported meaningful gains in marketer confidence and partner selection using that framework. See the event reference: AMA: The Influence of AI on SEO. Their post-event polling showed substantial increases in RFP readiness and agency selection using a criteria-based approach.
