How Does Voice Search Work?

When you make a voice search query on your smart phone or smart speaker, your voice assistant will get the information from different sources including search engines and major websites. The search engine used varies depending on the voice assistant that is used for the search.

When you make a voice search query on your Google Assistant or Google Home, the information will be pulled from the Google search index, Google Maps or YouTube. These Google properties will be used to search the web for a response to your query and Google Assistant will respond with a verbal response. When Google reads a response, it will list the name of the website that the information was pulled from.

When you make a voice query on Amazon Alexa, Alexa gets information from the Microsoft Bing search engine, Bing webmaster tools and Bing properties and will respond with a verbal response. Amazon Alexa can be used to make purchases from Amazon.

Apple Siri is used for voice search on Apple iPhone, Macs and Apple watches. Apple uses Google to search the web and return search results. For local searches, Siri uses Apple Maps.

Microsoft Cortana uses the Microsoft Bing search engine to search for information to search queries.

Your website must be SEO-optimized for voice search to ensure that it ranks well on the search engines and provides information to respond to voice queries relating to your products and services.

9 Effective SEO Strategies To Optimize Your Website For Voice Search

Your website needs to be optimized for Voice search as part of your SEO strategy. This ensures that your website ranks well for relevant keywords when customers search using voice commands.

1. Improve Organic SEO Rankings

Most responses to voice search queries are obtained from the top ranking pages on search engines. Your website must rank in the top pages using organic SEO practices on Google and Microsoft Bing.

On-Page SEO optimization of your website helps to improve its search rankings. On-page SEO includes optimization of the following items on your website with relevant keywords:
• Optimization of meta tags including title tags and meta description tags
• Optimization of content and headings
• Optimization of image alt tags
• Internal and external links

2. Optimize for longer conversational queries

Voice search queries tend to be longer and more conversational than typed queries.

For voice optimization, optimize your website content for long-tail keywords and conversational phrases that are 40 to 50 characters long.

For example, instead of optimizing for a keyword such as “smart speakers”, optimize for a long phrase such as “Which smart speakers are popular today?”

3. Optimize for questions

Voice searches tend to be oriented around asking questions like Who, How, When, Where, Why, Which and What.

Common questions include What is the time? What is the weather?

Optimize your website content to answer questions that are relevant to your products and services. Answers should be short.

4. Optimize for local SEO and “Near Me” Searches

People use voice queries on mobile phones when they search for information near them. You should optimize your website content for local SEO and include your city and geographic information.

You should also optimize your content for “Near me” searches. Get listed in local directory listings like Apple Maps and Google Maps.

• 22% of voice queries are focused on finding local business information (Internet Trends Report 2016).

• 500% growth in “Near Me” mobile searches that contain the terms “can I buy” or “to buy” between 2015 and 2017 (Google).

5. Optimize your Business Profiles in Google My Business and Bing Places

Your business listings in Google My Business and Bing Places For Business are important for local voice searches and to improve your local SEO rankings.

Google and Bing will use the business information listed in Google My Business and Bing Place listings for local searches. Ensure that your business information is up to date with the correct name, address, phone number, business hours, products and services.

6. Optimize for featured snippets

For voice queries, your website must be optimized for featured snippets.

In fact, featured snippets are used as responses for 40% of voice search queries on Google.

Featured snippets are the short answers to search queries that are featured on top of the organic search results and below the paid search ads. They are also called “position zero”.

Most featured snippets are drawn from the top 10 search results on the page. To be featured in “position zero”, you should optimize your content and your website must rank on page 1 for the search query.

To optimize your content for featured snippets, answer questions directly. Use customer questions as H2 headings and follow that with a short, one paragraph answer.

7. Use structured data

Since voice queries are in the form of questions, you should optimize your website with structured data. Structured data, or schema markup, on your website helps search engines to better understand your content and use them for the search results. Search engines use structured data to determine SEO rankings.

You can use FAQ and HowTo schema to optimize your content for questions related to your products or services.

8. Your Website Must be Mobile-Friendly with Responsive Design

Since most online searches today are made on mobile devices, including a large number of voice searches, your website must be mobile friendly with responsive web design. A mobile-friendly website will perform well and will be easy to read on mobile devices. It will provide a great user experience to mobile users.

A website that is Responsive will scale in size to fit the size of the mobile phone, laptop or desktop that the customer is using to browse your website. Responsive web design ensures that all the information is available and is easy to use on all devices.

9. Your Website Must Have Fast Page Speed

A fast website speed is important for voice searches since they are made using mobile devices. Having a fast loading web page is important for SEO.

53% of mobile site visitors will leave a website if it takes longer than 3 seconds to load (Google).

For your web page to load fast, make sure your images are small and compressed. You will also need to use page speed optimization techniques.
