Voice Search SEO

Is your business gaining new customers through voice search?

Introduction

At the moment, there is so much conversation about AI, GEO and Google AI Overviews. These are of course all are very important, and all businesses should be optimising for this. However, in 2025, as we move into 2026, there is less conversation about “voice search SEO”- therefore we thought we would write a comprehensive guide to help you to better optimise your website for those.

 

A word on Siri and Alexa

Think how millions of shoppers worldwide use Siri and Alexa to ask questions. For example, it could be something as simple as “Hey, Siri, where’s the nearest coffee shop that sells organic coffee?”

Therefore, if your website is set up for these long-tail, more conversational queries, then your business is more likely to be recommended by, say, Alexa or perhaps Siri.

 

Therefore, for this is to happen, the content marketing must offer the following:

– Answer the customer exact question
Be well written
Be helpful

Think about Google EEAT and how to optimise your businesses content marketing for this

Powerful way of drawing in more business

Often when a shopper gets recommend a business, by say Google, the shopper often follows up with a request for directions, which the smartphone delivers directly to your business. However, for your business to be recommended, the content marketing often needs to be high-quality and written in a more conversational style, with FAQ-style answers, so we will explain why your businesses marketing as whole needs to all work like clock-work in order for your business to be recommend by voice search.

 

For example, for local businesses, you will often need to:

– Have a well optimised Google Business account
– Be authoritative so have a lot of backlinks
– Have well written content marketing that directly answers the shoppers question
– Keep the work up to date
– Make sure that the website offers a good user experience, this means good design, simple to use, plus fast

 

Voice Assistants in the home and in the car

Voice assistants are used in the home, such as Google Assistant, Amazon Alexa, or perhaps Cortana or Apple’s Siri all over the globe. If you do use these to find products, you will know that each of these can find you an answer in the blink of an eye.

Therefore, for your business to be cited as an answer and appear as a business suggested to the customer, you must have excellent content marketing. There’s no point in publishing 500 words of marketing waffle, you have to often have better pages of blog posts than thousands of other businesses for your company’s content marketing to be cited as an answer. Therefore, aim to be the best, keep Google EEAT in mind, plus make sure that the work is written, or has direct input from an expert on that subject. Doesn’t matter if your writing about dentistry or the best hot tub to buy in 2026- make sure that you have input from an expert, in order to improve the Google EEAT score.

 

Here’s a quick overview of how you can optimise for these different systems:

– Longer form content marketing (aim for over 2,500 words of quality on blog posts)
– The text should have a high Google EEAT score (the written work should reflect your experience, expertise, authoritativeness and trustworthiness on that subject)
– Try to answer as many relevant questions in the text as possible

 

Convenience

What we have to remember as marketing companies is that people are often short on time today. Think about people who are say in a new city because they are visiting it on business, usually they need to ask various questions on voice search, such as where the largest car park is, where’s the best place for vegan food, and is there a gym they can visit on a one-off basis locally?

Therefore, this is where good local SEO ties into having good quality content marketing. Therefore, for your business to be cited as an answer

 

locally you must also improve the following:

– NAP signals
– Have a well optimised Google Business account
– Have content marketing relevant to local area
– Use schema
– Improve content thin pages
– Improve EEAT score
– Build local and powerful backlinks
– Think about the semantic web, get your business mentioned and talked about locally for say winning a business award

If your content marketing answers these questions, and your business gets cited more by say voice search or perhaps through Google’s organic results, alternatively, it might appear in the LLMs via ChatGPT- then you’re simply helping your business to generate more customers.

 

Natural Language Processing (NLP)

It used to be the case that copywriters and some businesses would try to add as many relevant keywords as they could. This is often called “keyword stuffing”- and it’s a rubbish, outdated form of search engine optimisation. It’s now much better to write naturally and to give the best possible advice you can.

You should talk about the products and services you sell as if a customer were standing directly in front of you. The information, therefore, needs to show that you’re an expert and that you’re trying to help the customer as much as possible. You’re not just off selling the benefits of a product or service (although important); you’re showing that you really want to help the customer and that you really understand the product or service you are selling.

 

In order to this, you should:

  • Write helpful guides
  • Write evergreen content marketing help guides
  • Write bespoke product descriptions
  • Make sure that you have NAP information on your website to gain more local customers
    Gain powerful backlinks

 

How voice search can help your local business

Picture the scene: it’s raining, someone is holding an umbrella, and they have toothache.

They’re likely to ask where the best private dentist is in the area. Now, if you’ve really worked hard to optimise your website, to explain why your best local business is, plus offering a lot of helpful advice, your company might be recognised by the voice search feature.

 

Yet to do this, your SEO agency should improve the following:

– Gain a lot of positive business reviews on your Google Business account
– Obtain high-quality backlinks
– Write helpful content marketing
– Think about Google EEAT, how this can be reflected in terms of how the content marketing is written
– Write in a conversational style
– Write using a lot of FAQ style content marketing
– Add a lot of helpful and valuable content marketing, but make sure it’s kept up to date

 

What are some of the more popular voice assistants that businesses should optimise for?

  • Google Assistant
  • Amazons Alexa
  • Microsoft’s Cortana
  • Apple’s Siri

How should our business change when writing our content marketing to be mentioned during more voice searches

Question-based content marketing

Don’t just write your content marketing with the idea of just cramming in as much information as possible. Instead, a big block of text is likely to be very dull to read (plus increase the bounce rate).

Therefore, write content marketing in an FAQ style, answering as many questions as your customers frequently ask your business. This way, not only will Googlebot crawl and index that work, and may cite it more often in Google’s organic results, but it also helps the voice search feature.

For example, if you’ve answered the exact question that the customer is asking, well, that’s going to be much more likely cited as an answer by, say, Alexa, simply because your answer is answering the customer’s precise question.

 

Long tail keywords

Long-tail keywords may not drive much organic traffic, but if you answer enough of them, it can definitely improve the number of visitors to your website. This can therefore start to increase sales.

 

Offering a good UX

It’s essential that you focus on improving site speed; this often means that web designers and the appointed SEO agency should take Google Core Web Vitals into account. Therefore, make sure the website is responsive and fast.

 

What are the key takeaways that you recommend in terms of optimising for voice search?

Create conversational content marketing.

So, our top tip would be simply this: improve your business’s content marketing in the following ways:

Long form

If you write long-form content marketing, you are often adding more relevant information. The more questions that you answer successfully, the more often your work will be cited. That doesn’t just mean for voice search; good content marketing is often cited by LLMs, Google’s organic search, and Google AI Overviews.

So, sure, as small or medium-sized businesses, you might be wondering, feeling slightly puzzled as to why you’re writing so much content marketing. Well, the reason is that it makes your business and your brand more visible.

If your brand is more visible, it is more likely to be cited more often.

Helpful

Do make sure that your content marketing is as helpful as possible. Many of the top SEO companies in the world will tell you that a significant and vital Google update was the Google Helpful Content Update. It was huge: businesses that wrote helpful content marketing were then ranked higher in Google’s organic results. Therefore, if your business is putting in the effort to write content marketing that helps customers, it will often rank much higher in organic results, helping you gain more business.

Google EEAT

When you’re writing your business’s content marketing, the only way it’s going to rank high in Google’s SERP’s and also be cited by voice search is if it’s high quality.

 

Therefore, do ask, will that piece of content marketing have a high Google EEAT score?

  • Is it well written?
  • Is it useful?
  • Is it the best you can write?
  • A lot of FAQ style questions and answers

 

Make sure you add as much detail as possible and answer as many FAQ questions as you can.

Be different

Think about Google for a second, think about all the millions of pages that it can cite, that it can offer as an answer to that question.
Whether the person is on ChatGPT, using a voice assistant in their car, or on Google.co.uk- looking for the best place to buy say a set of drums, what makes your page stand out?

What makes your business’s content marketing the best?

What makes it worthy of being cited?

 

Make sure you keep the work up to date

Nobody wants to read advice from 1999 if we are in 2025.
Therefore, do make sure that your business’s content marketing is kept up to date and is relevant. Its important to move with the times.
