Quick Answer: Voice search is how people ask questions out loud to Siri, Google Assistant, and Alexa. In Australia, one in three people use voice search daily, mostly for local queries. Voice searches are 6 to 10 words long versus 2 to 3 for typed searches, conversational in tone, and heavily local in intent. To rank in voice results: answer questions directly in the first paragraph of your content, target question-based keywords (who, what, where, when, how), maintain a complete Google Business Profile, and ensure your site loads in under 2 seconds. Voice search results load 52% faster than average pages.
Voice search is not the revolution it was once predicted to be.
It is also not irrelevant.
One in three Australians uses voice search every day, mostly to find local businesses nearby. 'Hey Siri, find a plumber near me.' 'OK Google, best cafe open now near Werribee.'
These are high-intent queries. The businesses in voice results are getting those calls.
How Voice Search Differs from Typed Search
| Typed search | Voice search |
|---|---|
| 2 to 3 words on average | 6 to 10 words on average |
| Keyword-style: 'dentist Melbourne' | Conversational: 'where is the best dentist near me' |
| User at a desk, can scroll results | User on phone or smart speaker, wants one answer |
| Returns a list of results | Returns one answer read aloud or displayed |
| Position 1 to 10 on page one | Only position zero/featured snippet gets read |
| Content can be long and exploratory | Answer must be in the first 2 to 3 sentences |
Who Answers Voice Searches
- Google's Knowledge Panel: For questions about your specific business ('Is Khalis Marketing open on Saturday?'), answers come from your Google Business Profile. A complete, accurate GBP is the most direct path to answering voice queries about your business.
- Featured snippets (position zero): For informational questions, Google reads the featured snippet from the page it determines best answers the query.
- Local pack results: For local service queries ('plumber near me'), voice assistants often read the name, address, and phone number of the top map pack result.
- AI-generated answers: In 2026, Google Assistant and Siri increasingly generate answers from multiple sources rather than reading a single snippet.
Optimising for Voice Search: Specific Actions
1. Target Question Keywords
Voice searches are questions. Use question-based headings throughout your content.
- 'How much does a plumber cost in Melbourne?' not just 'Plumber Melbourne pricing'
- 'Is teeth whitening safe?' not just 'Teeth whitening'
- 'What is the best time to call an electrician?' not just 'Electrician services'
The People Also Ask section of Google search results is a direct list of voice-style questions people are asking. Each one is a heading opportunity.
2. Write a Direct Answer in the First Sentence
The direct-answer format voice search rewards Question: 'How much does an electrician cost in Melbourne?' Opening answer: 'A licensed electrician in Melbourne typically charges between $100 and $160 per hour, with most standard callouts costing $200 to $400 depending on the job.' Then: expand with detail, exceptions, factors that affect price. The first sentence answers the question. The rest provides supporting context. Voice assistants read the first sentence. Human readers continue for depth.
3. Maintain a Complete Google Business Profile
- Hours must be accurate including public holidays. Voice assistants check hours for 'open now' queries.
- Phone number formatted correctly. Voice assistants read phone numbers from GBP directly.
- Q&A section: add common customer questions and answers directly in your GBP.
- Business description: write it in natural language that answers likely voice queries.

4. Page Speed Under 2 Seconds
Pages in voice search results load 52% faster than average. Google's voice engine prefers fast pages because voice users on mobile have no patience for slow loads.

5. Implement FAQPage Schema
FAQPage schema markup makes your question-and-answer content readable by structured data parsers, including the AI systems that generate voice responses.

Voice Search and AI Search Are Converging
In 2026, the distinction between voice search and AI search is narrowing.
When someone asks Siri or Google Assistant a question, the answer is increasingly generated by the same large language models that power ChatGPT and Google AI Overviews. Optimising for voice search and optimising for AI search are largely the same task.

Frequently Asked Questions
How many Australians use voice search?
Roughly one in three Australians use voice search daily, primarily for local queries (Red Search AU, 2026). 40% of consumers globally use voice search at least once daily, up 8% year on year.
Is voice search worth investing time in?
The optimisations that improve voice search performance also improve traditional SEO, AI search visibility, and featured snippet eligibility. The investment is not in a separate 'voice SEO' track. It is in better-structured content that serves multiple channels simultaneously.
