The search landscape has fundamentally shifted. Featured-snippet visibility declined by 35% between September 2024 and March 2025, creating intense competition for the remaining answer box real estate. Yet 42% of marketers who hired an SEO agency in 2024 achieved featured-snippet placements within six months, proving that specialized expertise makes the difference between visibility and obscurity in AI-driven search results.
Answer Engine Optimization (AEO) has emerged as the critical discipline for securing featured snippets, voice search prominence, and AI Overview citations. Unlike traditional SEO focused on keyword rankings, AEO prioritizes structuring content to become the definitive answer source across platforms like Google’s AI Overviews, ChatGPT, and voice assistants. The stakes couldn’t be higher. Brands that master AEO capture position zero while competitors fade into the crowded results below.
This comprehensive analysis evaluates 15 leading AEO SEO agencies based on their technical expertise, proven results, and ability to navigate the evolving AI search ecosystem. Ready to transform your search visibility? Get Your Custom Growth Strategy to explore your options.
