Voice Search Optimization: How to Win Siri and Alexa Answers
Voice queries pull one definitive answer, not a list. Here's how to structure your content so Siri, Alexa, and Google Assistant pick your business.
Voice assistants pull one definitive answer per query. To win that single slot, structure content as direct Q&A with FAQPage schema, mark voice-readable sections with SpeakableSpecification, target conversational long-tail keywords (5-9 words), and ensure your Google Business Profile has accurate hours, phone, and address.
Why voice search is winner-take-all
When you Google a question, you get 10 blue links and pick one. When you ask Siri the same question, you get one spoken answer. There's no scroll. No second place.
That makes voice search optimization (AEO — Answer Engine Optimization) the most ruthless form of search marketing. Either your content is the answer, or it doesn't exist.
How voice assistants pick the answer
Each assistant has its own data sources, but they all pull from a similar pool:
- Siri: Apple Maps for local, Bing for general queries, Wikipedia for definitions.
- Alexa: Bing for most queries, Yelp for local, Wikipedia for definitions.
- Google Assistant: Google Search featured snippets and Knowledge Graph.
All three favor: short, direct answers (around 30 words), strong schema markup, and authoritative sources.
Five things to ship for AEO
1. Direct-answer Q&A blocks
Write content in question-format with concise direct answers. Example:
How much does Zorva Labs cost? $55 per month, all-in. That includes the custom website, hosting, and monthly content changes.
That answer is exactly the right length for a voice assistant to read aloud — about 25 words.
2. FAQPage schema
Wrap each Q&A in FAQPage JSON-LD. This is the strongest signal that your content is answer-formatted.
3. SpeakableSpecification markers
Add SpeakableSpecification to your schema, pointing at data-speakable CSS selectors on your visible Q&A elements. This explicitly tells Google Assistant what to read aloud.
4. Conversational keyword targeting
Voice queries are longer than typed queries. People type "Nashville web design"; they speak "what's the best web design company in Nashville for small business." Target full natural-language phrases, not stems.
5. Google Business Profile completeness
For local voice queries (the biggest AEO category — "find a plumber near me"), your Google Business Profile is more important than your website. Hours, phone, address, photos, services — fill all of it.
Featured snippet structure
Google Assistant pulls heavily from featured snippets. To win one:
- Open the answer paragraph with the question itself, restated.
- Keep the answer to 40-60 words.
- Use a clear H2 with the question phrasing.
- If the answer is a list, format as actual
<ul>or<ol>markup.
