What is voice search optimization? Tips, tricks, and software tools
facebookfacebooklinkedinlinkedintwittertwittermailmail

Imagine that you’re in a mall for the first time and suddenly have a craving for pizza, and it must be vegan. How do you deal with that? Ask a random person where the food court is? Go to each food vendor and see if they have vegan pizza on display? 

Probably not. You take out your phone, right?

Of course. But what’s interesting is what you might do next. 

It’s become increasingly common for people to skip entering search terms in their search bar and instead use their smartphone (or other device) as a virtual assistant to do a quick voice search (especially if you’re hungry?). You hear smartphone users saying voice commands in natural language, like (to Apple’s Siri) “Where can I get vegan pizza around here?” Or “OK Google, where’s the best vegan pizza near me?” And whether they are using a mobile app voice search feature with their phone on the go or querying from their living room with their Amazon Echo smart speaker, this trend is going mainstream.

So, it follows that for businesses intent on success, voice search optimization for SEO (search engine optimization) is a necessity. SEO professionals, marketing managers, and content creators alike must rethink how they optimize their ecommerce websites, marketing campaigns, and content to reflect the growing emphasis on voice search technology. 

To help you improve your business’s voice search results, let’s explore how, who, when, where, and why you need to start incorporating words like how, who, when, where, and why in your content and keywords. Because using those question words is one of the ways to implement successful voice search optimization.

The voice search trend

More people are becoming comfortable with talking at, with, and to their phones rather than talking to other people on their phones. This trend reaches far wider than voice search alone, especially among the younger generations. One-direction types of speaking, such as vlogging, voice notes, TikTok, and Instagram Reels, are popular nowadays. It’s common to speak into a phone without expecting a human to respond. But crucially, it’s not just the younger generations that are embracing virtual assistants and voice search, it’s everyone.

A few statistics that illustrate this phenomenon:

  • Statista says there are more than 110 million voice search users in the United States
  • According to Capgemini, 70% of consumers use voice functionality to shop instead of going to stores
  • In 2024, there will be more digital voice assistants being used in devices (8.4 billion units) than people to use them

Research from Gartner suggests that the COVID-19 pandemic may also have played a role in driving up the number of voice searches. For starters, people stuck indoors may have had Amazon Alexa as their only (or preferred?) company. Also, when out in public, people felt less inclined to get out their phones and touch their screens if they could instead just talk hands free into their headset microphone and get an answer from Siri, Alexa, or Cortana.

How to optimize voice search for SEO

So voice search, whether it’s done using a mobile phone or through a digital assistant, is  transforming how people find what they need. And companies are turning to voice search optimization to meet the growing demand and make sure their customers can complete successful searches. 

What do you need to do to optimize your voice search apps? How can you make your voice search online perfect? How can you nail your local voice search SEO targets?

There are three main areas when determining an SEO strategy for voice search optimization: keywords and tone, website content, and opportunities for perfecting local searches.

Keywords and tone

If you think about how people use voice search — in particular, how they might frame their search query — you’ll notice some differences compared with doing a traditional online search. 

Let’s imagine that a woman is going to the Lincoln Memorial at 3 p.m. and wants to know what the weather will be like. Using a typed Google search, she might frame her query as “Weather Washington DC”, and quickly get the afternoon weather report.

If she sought the same information using Google voice search, she’d most likely express it as “What’s the weather forecast for Washington D.C. this afternoon?” Or “Will it rain in Washington D.C. today?” Or maybe “Siri, will I need an umbrella?”

A typical voice search:

  • Is almost always presented as a question
  • Is conversational
  • Is longer than a text string

It’s also worth noting that in a voice search, the speaker may assume some contextual understanding. For instance, if they want to research products and where they can buy them locally, they might assume that their location is known and not include this detail in their voice query.   

These parameters offer some tips for voice search optimization. You should use long-tail keywords in the form of questions. This means using those question words — How, Who, When, Where, and Why at the start of strings. Also, use a conversational tone in all content, including keywords, and include filler words such as the, of the, to, and for.

Website and content

How you structure content on your website is crucial to people’s voice-search success. Here are several factors to consider.

Target “rich” answers

Rich answers (or “rich results”) are the snippets of information that appear right above the search results. These results are extracted from high-ranking website content. They answer questions in what Google considers a comprehensive way.

Because voice search users expect a speedy response, it is rich answers — including featured snippets, knowledge graphs, knowledge panels, and knowledge boxes — that are surfaced. For voice search optimization, you need to create web content that could be candidate material for excellent rich answers.

This can be a challenge, but you can often achieve it by using a question that contains a longtail keyword as the header for a blog post or web page. The text that follows should be a short, succinct, and direct answer to the question you’ve asked.

Include frequently asked questions (FAQs)

Another effective practice is adding an FAQ page, or perhaps a few applicable FAQs at the bottom of a page. This works well because FAQ structure is a common question followed by a quick answer.

Optimize your website for mobile users

Because voice search is happening mostly on mobile devices, it is essential that your web pages be optimized for mobile.

Improve your site page speed

Because answers to voice search queries are needed at lightning speed, fast website page loading is needed for appealing to the algorithm. 

Opportunities for perfecting local searches

The majority of mobile voice search queries revolve around information about local places and conditions (like where to find that vegan pizza). Voice search related to local areas is not applicable for every type of business, but for hospitality and retail local businesses, it should be considered a key part of your marketing strategy.
