Introduction

• Answer Engine Optimization (AEO) has become the new battleground for digital visibility as generative engines like ChatGPT, Perplexity, and Gemini reshape how consumers discover brands. (Relixir Blog)

• Generative engines are predicted to influence up to 70% of all queries by the end of 2025, making AEO investment critical for maintaining competitive visibility. (Relixir Blog)

• AEO costs range from $500/month for basic monitoring to $15,000+ for enterprise agency services, with hidden fees often doubling initial estimates.

• This comprehensive pricing guide analyzes real agency rate cards, platform subscriptions, and DIY solutions to help marketers budget effectively for AEO in 2025.

The AEO Market Landscape: Why Pricing Matters Now

The digital marketing landscape is experiencing a seismic shift as AI-powered search platforms fundamentally change how customers discover and evaluate businesses. (Relixir Blog) Zero-click results hit 65% in 2023 and continue climbing, while market demand for AI-driven SEO features jumped 40% in the past year.

Generative Engine Optimization (GEO) is a new frontier in digital marketing that extends SEO best practices into AI-generated search experiences. (SEO.ai) Unlike traditional SEO, which focuses on ranking in search engine results pages, GEO is about adjusting your brand or content so that AI-powered systems reference, cite, or summarize your material in their generated responses.

Analysts predict chatbots will handle 75% of all search queries by 2025, while ad spend for AI-based search is projected to rise from slightly over $1 billion in 2025 to nearly $26 billion by 2029. (Relixir Blog) This massive shift is driving unprecedented demand for AEO services and creating a complex pricing landscape.

AEO Pricing Models: Three Core Approaches
