To appear in these “quality” search results, businesses need to adjust their SEO strategy flexibly. Below, MONA shares an effective voice search optimization strategy to help you catch the trend and reach the right audience in the digital age.

Research natural keywords for voice search

When optimizing a website for voice search, one of the most important steps is keyword research. Unlike text search, voice search users usually speak full questions with context, in a conversational way.

For example: instead of searching for “SEO services“, a voice search user will ask “which SEO service is reputable in Ho Chi Minh City?” hay “which company does the most effective overall SEO right now?”“.

So when researching keywords, don't stop at volume and CPC; also check whether a keyword suits a conversation. Useful tips for Google voice search keyword research that you can apply include:

• Focus on long-tail keywords in question form: “how do I…?”, “where…?”, “why…?”, and so on.
• Use tools such as Google Autocomplete, AnswerThePublic, AlsoAsked and Google's People Also Ask, to collect real conversational queries.
• Prioritize phrases with a natural tone like a real person speaking, instead of dry computer-style commands.

Choosing the right natural keywords not only raises traffic but also increases the chance your content is picked as the voice search answer.

Optimize content for Featured Snippets

A Featured Snippet not only makes it easier for your website to be picked as the answer to voice queries but also grows organic traffic. One way to raise your chance of being chosen is a clear, specific content structure such as:

Build and optimize voice-search-friendly content

Developing quality content has always been the “ace card” of website SEO. But as voice search grows more popular and users switch to speaking their searches, you need to create content with a natural, friendly tone, as in a conversation, that delivers real value instead of stuffing keywords.

To optimize content for Google Voice Search, first put yourself in the user's shoes. Instead of short keywords, focus on the long keywords they might ask, for example: “What is a reputable and effective SEO service for small businesses?“. 

Next, write the answer straight to the point. The answer should be short, easy to understand, split into clear paragraphs, with subheadings and lists so both users and Google can grasp the information easily. 

A few important notes for voice search SEO:

• Focused on long-tail keywords and conversational questions
• Understand search intent to meet users' real search needs

Optimize your website for mobile devices

According to Google statistics, up to 20% of all mobile search queries are made by voice. And this number keeps rising, especially as more people use virtual assistants like Siri, Google Assistant or Alexa to search faster and more conveniently. 

From these statistics you can see that making your website mobile-friendly becomes important when running a voice search SEO strategy.

• Optimize images and videos to keep quality while fitting load speed
• Optimize valuable content in a natural, friendly style, as if talking face to face
  Put frequently asked questions into your articles and apply FAQ schema so Google can extract and display them easily

Improve page load speed for Voice Search SEO

When users ask a virtual assistant, they expect an answer immediately. If your website loads too slowly, the chance of being read aloud by the assistant is almost zero. Page speed affects not only user experience but is also an important ranking signal for both Google and voice search. So if you want your content to be “recommended,” start by improving your page load speed.

You can check page performance with tools like Google PageSpeed Insights or GTmetrix to find the bottlenecks to fix. A few ways to improve page load speed:

• Compress images properly and avoid heavy images that slow the page
• Minify CSS and JavaScript so browsers load faster
• Enable browser caching so returning visitors see the page almost instantly
• Reduce unnecessary redirects
• Invest in quality hosting to avoid the “waiting forever for the page” problem
• By improving page load speed quickly, you not only keep users better but also raise your chances of conversion.

Using Schema Markup

Schema Markup is like an “interpreter” that helps your website communicate effectively with search engines. It is structured data that helps Google understand your page content not only through words but also through meaning.

When you use Schema Markup such as LocalBusiness and FAQ, the chance of your content being read aloud by a virtual assistant rises significantly. Besides supporting Voice Search SEO for your website, Schema also makes your content stand out in search results through rich snippets such as images, star ratings and prices, or even placement in the Featured Snippet, which has a high click-through rate (CTR) with no ad cost.

Multilingual optimization

When users search by voice, they usually speak naturally in their native language. If your website doesn't support that language, you lose the chance to appear in their search results.

To optimize voice search SEO for your target market, you need to run a multilingual SEO strategy as follows:

• Do keyword research for each language; don't just translate the content and reuse the original keywords. Use tools like Google Keyword Planner to evaluate keywords for each specific market.
• Configuration hreflang tag so Google knows which version fits users in each region and language.
• Create a separate URL for each language, for example /en/ for English and /vi/ for Vietnamese, so Google can tell them apart and you avoid duplicate content errors.
• Write in a conversational style that is simple and easy to listen to and understand, matching the way users talk when they use voice search.

Multilingual optimization not only helps you reach more people but also raises the chance of being chosen by a virtual assistant when users search by voice in any country.
