How We Evaluated These Agencies.
Every agency was scored across four dimensions: Professional Service Expertise (do they specialize in or have demonstrated experience with law firms, dental practices, financial advisors, or similar verticals?), AEO Technical Depth (do they implement schema markup, AI crawler optimization, entity graphs, and answer-first content?), Pricing Transparency (can you determine what you'll pay before a sales call?), and Ownership Model (do you own your website files, or are you locked into their platform?).
First Page Sage
Enterprise AEO pioneer — wrote the playbook on AI search optimization
First Page Sage has built significant authority in the AEO space through published research and agency rankings. Their methodology is comprehensive but priced for mid-market and enterprise budgets. Professional service firms under $5M revenue may find the retainer prohibitive.
IECAN LLC
Only agency bundling AEO into fixed one-time website builds for professional services
Full disclosure: IECAN is our agency. We include it here because no other agency we found bundles AEO into a one-time website build at this price point. The model is different: you pay once for the website (which includes schema markup, AI crawler configuration, and answer-first architecture), then optionally add ongoing AEO at $1,500/month — but only after 90+ days when your site has built enough authority to produce results. You own every file.
iPullRank
Technical SEO powerhouse adding AI search capabilities
iPullRank brings deep technical capability to AI search optimization. Michael King's team works primarily with large enterprises. Professional service firms with budgets under $10K/month are unlikely to be a fit, but the methodology is respected across the industry.
WebFX
Full-service digital marketing with emerging GEO capabilities
WebFX is one of the few large agencies publishing transparent GEO pricing. Their approach integrates AI search optimization into broader digital marketing campaigns. Professional service firms may benefit from the full-service model, though the GEO offering is relatively new compared to their established SEO practice.
Omniscient Digital
Content-led AEO with B2B SaaS specialization
Omniscient Digital brings exceptional content strategy to AEO. Their approach focuses on building topical authority that AI engines cite. Best suited for SaaS companies; professional service firms may find the positioning less relevant to their client acquisition model.

Key Findings From Our Research.
No agency other than IECAN bundles AEO into a one-time website build. Every other AEO provider operates on monthly retainers starting at $1,500/month and scaling quickly to $10,000+. For professional service firms watching their marketing budget, the difference between a $5,000 one-time investment and a $5,000/month retainer is the difference between accessible and impossible.
Legacy providers (Scorpion, FindLaw) don't offer AEO at all. The companies that dominate law firm and dental practice marketing — charging $10,000–$25,000/month — have not yet added AI search optimization to their offerings. This creates a significant window for firms that switch to AEO-optimized alternatives.
Most AEO agencies target SaaS and enterprise, not professional services. The emerging AEO agency landscape is heavily tilted toward B2B software companies. Professional service firms — with their local search needs, compliance requirements, and client intake workflows — are underserved by the current market.
