How much should a marketing agency charge for AEO monitoring services?

Entry-level monitoring + monthly report: $750-$1,500/mo. This is the 'we watch your AI visibility and send you a report' service. Low effort for the agency, good for retainer add-ons. Mid-tier monitoring + optimization: $2,000-$5,000/mo. This adds content recommendations, citation outreach, Reddit and forum engagement, and Share of Voice improvement work. It's where most agencies land for B2B SaaS clients. Full-service AEO retainer: $5,000-$15,000/mo. This includes everything above plus dedicated strategy, competitive intelligence, executive reporting, and coordinated content + PR work. Price anchoring matters: if your client already pays $8,000/mo for SEO, an AEO add-on at $2,500 feels reasonable. If they pay $2,000 for SEO, they'll resist $5,000 for AEO. The tool cost (Scenair, Profound, etc.) should run 5-15% of what you charge the client. The rest covers your strategy and execution time.
