Voice Search Optimisation: Preparing Your Website for AI Queries

“Hey Google, where can I find the best web design agency in Singapore?”

That one simple question captures how search is evolving — from keywords to conversations.

Voice search is now a user behaviour. With Siri, Alexa, Google Assistant, and AI engines like Gemini and Bing Copilot, voice has become the new search interface. Users now talk to search engines the way they talk to people — expecting smart, instant, and conversational answers.

This guide will show you how to optimise your website for voice and AI queries, using strategies that boost Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO) — the new frontier of SEO.

What Is Voice Search Optimisation?

Voice Search Optimisation (VSO) is the process of making your website discoverable for spoken, conversational queries. It aligns your content with natural language processing (NLP) so AI can understand questions, interpret intent, and deliver clear answers.

In voice search, people speak the way they think. Instead of typing “webflow agency singapore,” they say:

“Who’s the top Webflow agency in Singapore?”

This difference may seem small, but to AI, it’s a revolution.

Voice search optimisation means writing for people first, while structuring for AI. It’s the balance between empathy and engineering.

Why Voice Search Matters in 2025 and Beyond

The world is moving towards zero-click answers and AI-powered discovery. Voice search sits right at that intersection. Here’s why it matters:

• Half of all searches are conversational. People expect immediate, spoken answers.
• Voice assistants pull from featured snippets and structured data. If your content isn’t marked up, it’s invisible to them.
• According to Think With Google, around 27% of the global online population uses voice search on mobile.
• AI engines like Gemini, GPT, and Copilot rely on semantic clarity. Schema markup, intent mapping, and conversational phrasing make your site “answer-ready.”

The takeaway? Voice is now the filter through which AI understands user intent.

How AI Understands Voice Queries

When a user asks a question aloud, AI does more than transcribe. It processes meaning, tone, and purpose.

Voice queries tend to be:

• Longer (5–8 words on average)
• More natural and contextual
• Often framed as questions
• Frequently local (“near me,” “in Singapore,” “open now”)

To interpret them, AI uses a combination of Semantic SEO, Schema Markup, and entity recognition to identify the relationship between intent and your content.

Voice search is not about matching keywords — it’s about matching conversations.

How to Optimise Your Website for Voice and AI Queries

1. Use Conversational Language

Your content should sound human. Write in complete sentences that mimic how people naturally ask questions.

Example:‍

The not-so-good way: “UX design agency Singapore best”

The better way: “Which UX design agencies in Singapore have the best reviews?”

Avoid robotic keyword stuffing — AI models like Gemini and ChatGPT are designed to identify and ignore unnatural phrasing.

2. Answer Questions Directly

Optimise for Answer Engine Optimisation (AEO) by structuring your content around common questions. Include direct, 40–60-word answers immediately after each question.

Example:

Q: How does voice search affect SEO?‍

A: Voice search changes how users interact with content. Instead of typing, users ask complete questions. Websites that use conversational language and structured data are more likely to appear in AI-generated answers.

Add FAQ sections using FAQPage Schema for maximum visibility.

3. Optimise for Long-Tail, Conversational Keywords

Voice queries are longer and more specific. Tools like AnswerThePublic and AlsoAsked reveal real-world voice-style questions.

Target keyword formats such as:

• “How much does it cost to…”
• “Where can I find…”
• “What’s the best way to…”

These align perfectly with AI’s question-answer retrieval systems.

4. Implement Speakable and FAQ Schema

Schema is the structural backbone for voice SEO.

Add Speakable Schema to highlight text suitable for voice playback, and pair it with FAQPage Schema to expand your answer reach.

{
  "@context": "https://schema.org",
  "@type": "SpeakableSpecification",
  "xpath": [
    "/html/head/title",
    "/html/body/div[1]/h2"
  ]
}

Validate your code using Google’s Rich Results Test.

5. Optimise for Local Voice Search (GEO Optimisation)

Most voice searches have local intent:

“Find a web design agency near Orchard Road.”

If your business operates in Singapore, ensure your LocalBusiness Schema, Google Business Profile, and NAP (Name, Address, Phone) are consistent across your website and directories.

Include geo-specific terms such as:

• “Webflow agency in Singapore”
• “UX consultant in Marina Bay”
• “SEO agency near Bugis”

This signals locality to AI models and helps you appear in AI-generated summaries for Singapore-based voice queries.

6. Create Snippet-Ready Content

Voice assistants like Siri or Alexa pull answers directly from featured snippets. To optimise for these:

• Use question-based headers (H2/H3).
• Provide short, scannable answers right after.
• Use lists, bullet points, and definition-style formatting.

The goal is to become the answer — not just another search result.

7. Improve Mobile Experience and Speed

Since most voice searches happen on mobile, your website must load fast and feel frictionless.

Use PageSpeed Insights or Lighthouse to identify delays. Focus on:

• Optimising images (WebP format)
• Lazy loading
• Streamlined navigation
• Minimal pop-ups

AI favours mobile-first, fast-loading sites because they signal good UX — and UX directly affects ranking in voice and AI results.

Voice Search, AEO, and GEO: The Perfect Trifecta

Voice Search Optimisation feeds AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation). Here’s how they connect:

Together, these ensure your content is both answerable and contextually visible to AI.

Voice Search in Singapore: A Rising Trend

Singapore’s mobile-first culture makes it a prime market for voice-driven SEO. From young professionals asking Siri for lunch spots to marketers using Gemini for insights, voice-based interaction is becoming mainstream.

For web design and UX agencies, voice SEO offers a competitive edge — especially when combined with AI-driven UX and Schema-based visibility.

Common Mistakes to Avoid

1. Keyword stuffing: AI filters out unnatural phrasing.
2. Ignoring structured data: Without Schema, your content isn’t “readable” by AI.
3. Neglecting local SEO: Voice queries are often location-driven.
4. Slow mobile UX: Voice users expect immediate answers.

Frequently Asked Questions (FAQs)

What is the main difference between voice search and traditional SEO?‍

Traditional SEO focuses on typed keywords, while voice search focuses on spoken, conversational phrases. Voice optimisation ensures that your content matches how people ask questions naturally.

Do I need special tools to optimise my website for voice search?‍

No specialised tools are required, but using structured data generators, Google’s PageSpeed Insights, and schema validators can significantly improve your voice search readiness.‍

Is voice search important for small businesses in Singapore?‍

Absolutely. Many Singaporeans use mobile and voice assistants to find nearby services. Local businesses that optimise for voice queries stand out in AI-generated results.

How can I measure the success of voice search optimisation?‍

Track metrics such as featured snippet appearances, mobile impressions, and local search visibility in Google Search Console. Over time, increased traffic from mobile and local results indicates better voice SEO performance.

What’s the role of Schema Markup in voice search?‍

Schema helps AI and voice assistants understand your content. Implementing Speakable and FAQ Schema improves your chances of being selected for voice responses.

Conclusion

Voice search is changing the rhythm of discovery.

People are no longer typing for information — they’re asking for it. And AI is listening carefully.

When your website uses conversational phrasing, structured data, and local relevance, you’re building a bridge between user intent and AI understanding.

The question isn’t whether your brand can be found — it’s whether it can be heard.
