Voice search fundamentally changes how queries are formulated. Instead of typing "weather Paris", the user says "what is the weather in Paris today?". This seemingly minor difference has major SEO implications: voice queries are longer, more precise, almost exclusively informational, and phrased as questions addressed to a human interlocutor.
Characteristics of voice queries
They typically begin with interrogative words: how, why, what is, where to find. They are generally expressed in everyday language, without the abbreviations typical of text search. On mobile, they are often associated with local intent ("restaurant near me").
Optimizing for voice search
Pages that perform in voice search meet the same criteria as AEO: direct answer at the section opening, content structured as Q&A, natural language, and FAQPage and HowTo structured data. Google often reads the featured snippet as the voice response. Content optimized for voice search is therefore automatically optimized for conversational LLMs.
Voice Search and LLM interfaces
The conversational interfaces of LLMs (ChatGPT Voice, Gemini) push this logic even further. The user engages in natural language, and the LLM selects sources that best respond to the expressed intent. The distinction between voice search and GEO is becoming increasingly blurred.
