What is voice search optimization?

Voice search optimization is the process of upgrading and streamlining the information on your pages to appear in voice searches. Voice search optimization aims to optimize your page to answer the questions for people when they conduct verbal searches. This process allows you to have a chance to get your page read by the voice search device(Alexa, Siri, OkGoogle) whenever the user asks for information related to your page.

And 66.3 million U.S. households are forecasted to own a smart speaker in 2022.

Statistics on Voice Searches that is sufficient to convince anyone on why is voice search optimization so crucial:

The Importance of Voice Search

It's no secret that voice search is on the rise. In fact, 58% of consumers use voice search to find information about a local business online. (Source: Search Engine Journal). That's a pretty big number, and that's why it's so important to start optimizing your website for voice search today.

So, what can you do to make your website more voice search friendly? Here are a few tips:

1. Make sure your website is mobile-friendly. More and more people are using voice search on their mobile devices, so it's essential that your website is responsive and easy to navigate on smaller screens.

2. Use long-tail keywords in your content. Voice search is particularly good at answering specific questions, so using long-tail keywords will help you target those queries.

3. Make sure your content is accurate and up-to-date. One of the main complaints about voice search is that results can often be inaccurate. To avoid this, make sure your website's content is accurate and up-to-date.

How does automatic speech recognition system work?

The automatic speech recognition system (ASR) is a technology that converts voice impulses into text for the purpose of voice search. This allows users of smart devices, such as smartphones, smart speakers, and cars, to perform voice searches using voice recognition technologies. The voice search engine converts the spoken words into text and analyzes it in the same way as a traditional search query, presenting relevant search results. Machine learning and artificial intelligence (AI) are constantly improving the accuracy and efficiency of voice search by better understanding human language and the searcher's intent. AI also helps to enhance audio quality and extend battery life for personal voice assistants. As a result, voice search systems are now able to more accurately understand and respond to requests and instructions given by users.

Basically, the process is as follows: 

ASR software detects speech when an individual or group speaks.  The device then records the words it hears in a wave file. The wave file is treated to adjust volume and remove ambience. 

The sequences of this filtered wave pattern are then broken down and looked at. 

The automatic voice recognition software analyses these sequences and then using statistical likelihood to recognise the individual words before going on to whole sentences.

Voice Search Optimization Tricks

Keyword Research as a part of voice search optimization

Google relies heavily on featured snippets and knowledge graphs to answer to voice queries of people. As the intent behind voice search is to get quick and immediate results, voice search devices try to give instant results with the help of rich snippets and knowledge graphs. Having a high domain rating is also crucial.

Now, what is the featured snippet?


Google Featured Snippet

Features snippets are short answers to the user's question and are extracted by Google from pages already ranked on the first page to give a brief description(about the query) and enhance user experience. Rich snippets are positioned above the organic results, and they could be in the form of paragraphs, tables, numbers, bullets, charts, graphs, images, YouTube videos, carousels, etc.

If your page is optimized for featured snippets, it is a clear indication that your web page answers the user's question. According to the reports, featured snippets get around an 8% click-through rate. Hence there is a chance of a high CTR. Read the differences between digital marketing vs traditional marketing.

What is a knowledge graph?


Google Knowledge Graph

The Google knowledge graph is a humongous database of information that allows Google to provide the quick and right information to the user's queries. The data for the knowledge graph is collected from various sources, be it publicly accessible or privately licensed. 

As the knowledge graph can answer most of the queries, Google always looks at the pre-existing knowledge graph to answer the voice searches, which, however, reduces the organic click-through rate.

9 Strategies for voice search optimization:

1. Voice search queries have question words. Hence, use question keywords and long tail keywords

2. Use Schema Markup to improve the relevance of your content

3. Having an FAQ section would provide an immediate and short description as the answer to their question

4. Create detailed and informative content with your customer persona in mind

5. Ensure that your website loads fast

6. Your website has to be mobile friendly

7. Optimize your website with local SEO techniques to rank for "Near Me" voice queries

8. Multilingual SEO for Voice Search

9. Improve Your Microdata

1. Question Keywords and long-tail keywords are necessary for voice search optimization.

Question Keywords and long-tail keywords are necessary for voice search optimization.

Keyword Research for Voice Search Optimization

If you notice on a general level, people tend to ask the entire question when using voice search devices instead of just putting the short-tail keywords. For example, you would ask, "Hi Alexa! (or Hey SIRI, or Ok Google!), how do I optimize my website for search engine optimization with the help of an SEO agency". On the other hand, if you had to type the same thing, you might have targeted the short tail keyword like SEO agency, website SEO optimization, etc. The main point behind the difference is that when people type, they have to take a larger amount of pain and spend a longer amount of time searching for the complete query. Thus, they prefer to go with the short tail keywords and see what Google has to offer.

On the other hand, voice searches have made it easier for people to search their long questions without spending much time and energy. Voice search devices are very accurate now to analyze the user's question, and maybe this is why 60% of people never want to go back to the old time of typing the entire thing.

Voice search queries generally have many question words. Thus you should add keywords like how, what, where, when, why, etc., to make your content more relevant for voice search. As discussed above, long-tail keywords make more sense for voice searches. Hence, for no good reason in this world, you could ignore long-tail variations of the keywords.

The average Google voice search result is at ninth-grade level (Source: Backlinko), which means all the fancy vocabulary and difficult words may harm your chance to appear in voice search results. Instead, you could use this opportunity and put conversational content that will resemble the language people use while using voice assistants. You could use filler words like "I, the, of the, on the, to, for, a, me," etc.

2. Use schema markup to provide context to your content.


Schema markup is the structured data markup

Schema is the structured data markup that helps the search engines to make sense of your content. Schema markup has a great influence on SEO, mainly rich snippets. The purpose of schema markup is to make your site discoverable by search engines as they give a complete picture of what your content is all about and your intent.

When you adopt schema markup for your voice search strategy, you are simply helping the search engines with an indicator of intent and relevancy.

3. Ensure that you have an FAQ section


FAQ section is crucial for voice search optimization

Most voice searchers begin their search with a question that starts with "Who, What, Why, How, When, etc." It means they need an immediate and short description as the answer to their question. You could use the FAQ section on your pages that gives attention to all the related questions to your target keyword that the searcher may have.

You must answer all these questions in a conversational tone to appeal to the voice search. Your website and web page must be technically sound and include schema markup to help search engines better understand the content. You must make sure that the navigation and informational structure is easy to find and your page loads at a good speed.

4. Know your customer persona and create the right type of content for your persona

Know your customer persona and create the right type of content for your persona

Customer persona

Conciseness, ambience, and relevance are crucial for your voice search strategy. The way a millennial would use voice search is different from a Gen Z or Gen Alpha. Thus, create a customer persona and use it to dig deeper into the content you create to help your persona with the most relevant information. You could create a webpage with a headline that covers the most common question. 

Next, you could provide a detailed answer or definition to the keyword. After this stage, you could elaborate details on the topic to solve every pain point of the searcher. Also, focus on the digital marketing funnel while creating the content.

5. Ensure that your website loads fast

Fast loading is crucial for voice search optimization

Fast loading speed is crucial

Website loading speed is a crucial factor for SEO and voice search. It directly impacts the bounce rate and needs to be optimized as soon as possible. When you notice the purpose behind voice search, you realize that the searcher needs quick answers. 

On the contrary, if you have a slow website that takes gazillions of years to load, no search engine would use them for answering the questions. Hence the entire purpose and optimization process fails if your website is not updated and loads fast.

6. A mobile-friendly website is crucial for your voice search optimization strategy.

The mobile experience is crucial for the growth of your website in terms of SEO and voice search optimization. In 2019, Google announced how mobile experience directly impacts your website ranking. This update was made with an eye on how the mobile users increased significantly. It is often suggested to have a mobile-first approach:

Have a responsive website. Make sure that your website passes the mobile-friendly test. Also, your website should be crawlable by Google spiders.

7. Perform local search optimization to rank for keywords relevant to your business in a given location and appear for "Near Me" queries.

Local SEO is the process by which you optimize your website to appear for local search results. It is crucial for any business with offices in a specific location or to appear for searches made in a particular area. You would be amazed to know that 46% of searches performed on Google are meant for local queries. 

In terms of voice search optimization, local SEO is crucial because if you perform a "Near Me" voice search regarding any business, voice search devices like Siri, Alexa, etc., would read out the names of the listing chronologically.

8. Multilingual SEO for Voice Search

Did you know that Google can recognize about 120 different languages for voice search? While this is great for user experience, it can make ranking highly challenging, especially if your site receives visitors from all over the world. In this case, focusing on multilingual SEO and paying special attention to voice search is essential.

Keep in mind that people tend to use voice search in their native language, making multilingual SEO especially important. If you do not optimize for multiple languages, visitors searching in their native tongue will not be able to access your website.

Hreflang annotations are crucial for websites that support multiple languages. These annotations allow Google and other search engines to determine which version of a website to show to specific users based on their language preference. For example, hreflang enables Spanish users to view the Spanish version of a website and English speakers to view the English version. It is also recommended to use the "alternate" attribute in conjunction with hreflang to inform Google that the page is a translation rather than a duplicate of another webpage. This helps prevent issues with duplicate content.

9. Improve Your Microdata

To make your website more easily crawlable and understandable for Google, it's important to submit your Google My Business information and create a sitemap that includes details such as the prices of your products, directions to your location, your store's operating hours, and your contact information. You can also use microdata to help Google understand your content better. Add markups for different usage scenarios to enhance your website's microdata. By doing these things, you increase the chances that Google will use your website's content to answer voice search queries.

What distinguishes voice search from text search? 

Voice search is a type of search that is performed using voice commands or spoken phrases rather than typed keywords. When you use voice search, you can ask a question or make a request using natural language, just like you would when speaking to another person. This contrasts to text search, where you type keywords or phrases into a search box to find information.

Voice search differs from text search for several reasons, including the conversational nature of voice search queries and the use of spoken language. Voice search queries tend to be longer and more descriptive and may include words or phrases that are not commonly used in text searches. Voice searches are also often conducted in a specific context, such as when a user is driving or performing a task around the house. The results must be relevant to the user's location, situation, or needs. To optimize for voice search, it is important to create content relevant to the user's query, uses natural language, and considers the user's context and personalization. Although voice search tends to use complete sentences, it is also specialized. When speaking to a digital assistant, people tend to be more concise and specific with their requests, possibly because a more concise question results in a more precise response. Enabling a user's location can provide accurate results for searches such as "Find an Italian restaurant nearby." As a result, business owners should tailor their websites and content to accommodate simple but precise searches. To achieve this, it may be useful to create a thorough FAQ page or a blog with authoritative material written around long-tail keywords and specific but general questions. To do this effectively, it is important to research the types of questions that your target audience commonly asks digital assistants and create content that addresses those issues.

Best Practices for Voice Search Optimization

Now that you know the basics of voice search optimization, it's time to put that knowledge into practice. Here are a few best practices to help you get started:

1. Make sure your website is mobile-friendly. Most voice searches are conducted on mobile devices, so your website needs to be optimized for mobile users.

2. Optimize your content for question-based keywords. When creating content, try to use keywords that people are likely to ask in a voice search.

3. Use natural language in your content. When writing website copy, use the same language that people would use in a normal conversation. This will make it easier for search engines to understand your content and rank it higher in the results pages.

4. Increase the frequency of your backlinks. Backlinks are still an important factor in SEO, so make sure you're including links to your website from other authoritative sources.

5. Use structured data markup on your website. This will help search engines better understand the content on your website and return more accurate results when users conduct a voice search.

6. Use short, concise titles and descriptions. When people use voice search, they typically only say a few words at a time. Make sure your website's titles and descriptions are easy to understand and relevant to your target audience.

Google’s BERT Algorithm: How it relates to Google’s focus on voice search optimization

Many SEO experts, marketers, and specialists believe that Google's BERT algorithm will have a significant impact on search engine marketing and voice searches. BERT stands for "Bidirectional Encoder Representations from Transformers," and it uses machine learning and Natural Language Processing (NLP) to better understand the context of search queries. Google refers to it as "State-of-the-Art Pre-training for Natural Language Processing," and its goal is to improve the search experience for users and to require businesses to adapt their search engine strategies to the algorithm.

It is particularly effective at handling more complex or conversational search queries, as it is able to consider the relationships between words in a sentence and understand the intent behind the search. This enables BERT to provide more accurate and relevant search results, helping users find the information they are looking for more easily. As more people use voice assistants like Google Assistant to search for information, Google needs to be able to understand the context and meaning of spoken search queries in order to provide accurate and useful results. BERT is important because it can understand the meaning behind a search question and consider the connections between words in a sentence, which helps improve the accuracy and relevance of voice search results.

Is voice optimization important for local businesses?

Yes, voice optimization is very important for local businesses. Voice optimization helps businesses appear in voice search results, which is an increasingly important way for customers to find local businesses. For example, voice search is used by many customers to find nearby businesses, making it critical for local businesses to appear in the results. 

Voice optimization can also help businesses build brand recognition, create better customer experiences, and increase their visibility in local search results. Optimizing content for voice search can also boost a business’s credibility and trustworthiness, as customers are more likely to trust a business that appears in voice search results than a business that does not. Additionally, voice optimization can help businesses reach customers more quickly and easily, as voice search results are often faster and easier to access than traditional search results. With the growing popularity of voice search, local businesses should make sure to optimize their content for voice search to stay competitive.

Voice optimization and its importance for people with disabilities? 

Voice optimization is an important technology for people with disabilities. It helps them to communicate more easily and accurately and can even improve the quality of their lives. For people with disabilities, communication can be a challenge. They may have difficulty speaking due to physical impairments or neurological conditions. In some cases, they may be completely non-verbal. This can make it difficult for them to communicate their needs, or even to interact with other people.  Tech can help to bridge the gap. It uses artificial intelligence (AI) and natural language processing (NLP) to recognize the user’s voice and understand what they’re saying. It can then convert the user’s speech into text, allowing them to communicate more effectively. That's pretty awesome. 

This optimization can help improve the quality of life for people with disabilities. For example, it can be used to control devices such as computers. This allows people with physical impairments to stay safe and independent. It can also be used to access educational resources, helping those with learning difficulties to learn more effectively.

I know that we are focusing on performance, and targeting bigger groups, but it can make a real difference to the lives of people with disabilities. It can provide them with independence and autonomy, and help them to communicate more effectively. It’s an important technology that is changing the lives of many people with disabilities, and it’s set to become even more important in the future.

Test if your website is compliant with disability rules.


The best way to test if your website is compliant with disability rules is to use automated tools such as accessibility checkers. These tools will check for a range of criteria and provide a report on any issues that need to be addressed. Additionally, you can find organizations that offer manual testing of websites for WCAG compliance. 

If your website is to be accessible to users with disabilities, it is important to ensure it meets the standards set out in the Web Content Accessibility Guidelines (WCAG). To test if your website is compliant, you can use automated tools such as accessibility checkers. These tools will examine your website against a range of criteria and provide a report on any issues that need to be addressed. For example, voice search technology is becoming increasingly popular, so it is important to make sure your website is accessible for voice search. Automated tools can check for voice search compliance and provide a report on any potential issues.

In addition to automated tools, organizations such as Accessible360 offer manual checks for WCAG compliance. Their experienced accessibility professionals can review your website and provide a detailed report on any issues that need to be addressed. This service is valuable as it can detect issues that automated tools cannot detect.

Ultimately, testing your website for WCAG compliance is essential to ensure it is accessible to all users. Automated tools and manual checks can provide valuable insights into any issues that need to be addressed. By ensuring your website meets the standards set out in the WCAG, you can make sure it is accessible to everyone.

Are there disadvantages to voice search optimization?

Of course, nothing is perfect. Here are a few we still identify:

   1. Limited Search Depth: Voice search optimization is still in its infancy, and many voice assistants cannot hone in on the details of a query like a traditional search engine can. This means you may not get as deep of a search result as a traditional search engine.

   2. Privacy Concerns: Voice search optimization requires automated systems that can record and store user queries and responses. This raises many privacy concerns since users may not be aware of what data is being recorded and what it is being used for.

   3. Limitations of Technology: voice search optimization is still in its early stages, and it is not yet able to understand all nuances of language. This can lead to inaccurate search results and may be frustrating for users.

   4. Cost: Implementing voice search optimization can be expensive and may not be financially feasible for smaller businesses.
