In 2022, around 142M people in the US used voice assistants. By 2026, that number is expected to jump to 157.1 million voice search users. So, it’s a smart move to include voice search optimization in your strategy.
If you are new to the topic, don’t worry. This post will cover everything you need to know about voice search optimization (VSO), including what it is and how to optimize your site to be discovered when people use their voice to search.
It is all about enhancing your online visibility so that you show up in voice search results. The main aim is to be chosen and read out loud by voice assistants when people use voice search.
These digital helpers include Google Assistant, Apple’s Siri, Microsoft’s Cortana, and Amazon’s Alexa.

Voice search is quite different from the usual text-based search. The way we ask questions changes a bit.
For example, if you want to find an Italian restaurant close to you, you might type “ Italian restaurant near me” into a search engine.
But you’re more likely to phrase a voice search query like this: “Hey, Siri, can you find an Italian restaurant nearby?” We interact with our voice assistants as if they were actual people.
This means voice search queries tend to be more conversational, longer, and often come out as complete sentences or questions.
To get picked up by voice assistants, you need to optimize for these kinds of queries.
The Importance of Voice Search Optimization for SEO
Optimizing for voice search helps you reach more people than optimizing for text-based searches alone.
According to Statista, the use of digital voice assistants is projected to keep increasing.

In five years from 2019 to 2024, the number of digital voice assistants increased over 2 times. Many people use them for routine tasks like setting alarms or playing music. But people also use digital assistants to find information.
To increase the chances of appearing for voice search queries, you should use strategies that will also help your overall SEO. Focus on speeding up your website, incorporating voice search keywords into your content, and ensuring your site is mobile-friendly.
