"Hey Google, who's the best SEO consultancy near me?" Every day more people speak their searches instead of typing them, and voice assistants reply with a single spoken answer. Voice search optimisation is how you make sure that answer features your brand.
What is voice search optimisation?
Voice search optimisation is the practice of structuring content so voice assistants, Siri, Alexa, and Google Assistant, select it as the spoken answer to a user's question. Because voice typically returns one answer rather than a list, the prize isn't a ranking, it's being the answer. That makes it a close cousin of Answer Engine Optimisation.
How voice queries differ
- Longer and conversational. People speak in full questions: "what's the best way to..." rather than "best way".
- Question-led. Who, what, where, when, why, and how dominate.
- Single-answer. The assistant reads one response, so second place is invisible.
- Often local or immediate. Many voice searches are on the move, overlapping with local SEO.
How to optimise for voice search
- Answer questions directly. Lead with a concise, spoken-friendly answer, then expand.
- Write conversationally. Match how people actually speak, including natural question phrasing.
- Use FAQ formats. Q&A structures map perfectly to voice queries.
- Add Speakable and FAQPage schema. Tell assistants which passages to read aloud.
- Keep facts accurate and current. Assistants favour trustworthy, up-to-date sources.
With voice, there's no page two. You're either the answer the assistant speaks, or you're silent.
Voice and AI search are converging
The line between voice assistants and AI answer engines is blurring fast, both deliver a single synthesised answer to a natural-language question. Optimising for voice therefore strengthens your AI visibility as a whole. The same concise, well-structured, schema-rich content wins in both.
