Voice Search Keyword Research: Step-by-Step Guide

Voice search is no longer a niche – it’s powering 43% of online searches and is expected to grow further in 2025. With users speaking in natural, conversational phrases, businesses need a fresh approach to keyword research. This guide breaks down how to optimize for voice search, focusing on question-based, long-tail keywords that align with how people talk to smart devices.

Key Takeaways:

• Voice Search Behavior: Users ask full questions like, “Where’s the nearest coffee shop?” instead of typing short phrases.
• Why It Matters: 78% of voice search results come from featured snippets, so targeting conversational keywords can secure the top spot.
• How to Research Keywords:
  • Use tools like AnswerThePublic, SEMrush, and Google’s People Also Ask to find natural language queries.
  • Add local intent by including terms like “near me” or city-specific phrases.

Voice search is about understanding how people naturally speak and meeting them where they are – through conversational, action-driven content.

Ultimate Voice Search SEO 2025 Guide

Step 1: Understanding Voice Search User Behavior

To optimize for voice search effectively, you need to start by understanding how people actually use it. Voice search isn’t just typing spoken aloud – it’s a whole different ballgame. These differences in behavior will shape your keyword strategy and overall approach.

Common Voice Search Use Cases

Voice search has become a go-to tool in daily life, especially for quick, hands-free answers. Here are some of the most common ways people use it, and why these scenarios matter for your strategy.

Local business discovery is one of the top reasons people turn to voice search. Questions like "Where’s the closest coffee shop?" or "What time does Walmart open?" are typical. These queries are hyper-focused on location and urgency – users want immediate answers, not a list of websites to sift through.

Navigation and directions are another big use case. Whether driving or walking, people rely on voice commands like "How do I get to Times Square?" to get real-time, turn-by-turn guidance. The convenience of hands-free navigation makes voice search a natural fit for these on-the-go moments.

Quick factual questions are also driving voice search usage. People ask about the weather, sports updates, store hours, or even unit conversions like "How many cups in a gallon?". These queries reflect an expectation for fast, precise answers – no one’s looking to scroll through search results here.

When multitasking, voice search becomes an indispensable tool. Whether cooking, shopping, or tackling household chores, people use it to get practical, screen-free answers. This context shapes the kind of queries users make, often focusing on immediate, actionable information.

These everyday scenarios highlight the unique ways voice search is woven into people’s routines. They also underline how important it is to tailor your strategy to match these real-world behaviors.

How Natural Language Changes Search Queries

Switching from typing to speaking changes everything about how people search. Voice queries are more conversational, and understanding these patterns is key to crafting an effective keyword strategy.

Unlike typed searches, voice queries are often full sentences or complete questions. Instead of typing "clean hardwood floors", someone might say, "What’s the best way to clean hardwood floors?". This shift means you’ll need to focus on longer, more detailed phrases when researching keywords.

Question words like "how", "what", "where", and "why" are central to voice search queries. These words often kick off the search, reflecting a conversational tone and a desire for direct answers.

Casual language and contractions are another hallmark of voice search. People naturally say things like "What’s the weather like today?" instead of "weather forecast." Phrases like "Can you tell me" or "I need to find" are common in voice searches but rare in text-based queries. This shift demands a more conversational approach to keywords.

Age also plays a role in query style. Baby Boomers tend to ask longer, more detailed questions, often looking for thorough information. Gen X blends specific and general queries, while Millennials and Gen Z favor short, casual phrases, often from their mobile devices. Meanwhile, Gen Alpha kids stick to short, direct commands.

Finally, the intent behind voice searches often leans toward action. People use voice search for things like making purchases ("Order pizza near me"), getting quick help ("How do I fix a running toilet?"), or direct navigation ("Call the nearest pharmacy"). These action-driven queries influence both the structure and tone of voice searches.

These examples show why traditional keyword research often misses the mark when it comes to voice search. People expect natural, conversational interactions that mimic how they’d talk to another person. To succeed, your keyword strategy needs to reflect these longer, question-based queries and address the immediate, practical needs that drive voice searches.

Step 2: Finding Conversational and Long-Tail Keywords

When it comes to voice search, picking the right conversational keywords is key. These keywords are quite different from the traditional ones – they tend to be longer, more conversational, and often framed as full questions. With the right tools and techniques, you can identify natural language phrases that reflect how people actually speak.

Tools for Finding Voice Search Keywords

Here are some go-to tools for discovering question-based, conversational keywords:

• Google’s Built-In Features: Start with Google’s "People Also Ask" section. When you type a keyword like "SEO tips", you’ll see real questions people are asking, such as "What are the best SEO tips for beginners?" or "How do I improve my website’s SEO ranking?" These questions often mimic how users phrase their voice searches.
• Google Autocomplete: As you begin typing a query, Google suggests completions based on popular searches. These suggestions often include conversational phrases like "how to", "what is", or "where can I find."
• AnswerThePublic: This tool is excellent for generating lists of user questions based on who, what, when, where, why, and how. It’s perfect for uncovering detailed, voice-friendly phrases.
• SEMrush and Ahrefs: For more advanced research, these platforms provide question-based keyword suggestions, along with metrics like search volume and difficulty. SEMrush, for instance, offers a free plan with limited reports, while paid plans start at $139.95/month and include up to 10,000 results per report.
• LowFruits: This tool specializes in identifying low-competition, long-tail keywords – ideal for voice search optimization. Since voice queries are often specific, LowFruits can help you uncover opportunities that broader tools might miss.

Start with a seed keyword and use these tools to generate conversational variations. For example, a simple term like "keyword research tools" can evolve into "What are the best keyword research tools for small businesses?" – a format that aligns perfectly with how people speak during voice searches.

Adding Local Intent Keywords

Once you’ve gathered conversational keywords, it’s time to add a local twist. Voice search often revolves around location-specific queries, making it crucial to include geographic modifiers in your strategy. These modifiers help capture users looking for immediate, nearby solutions.

Start with common phrases like "near me" and expand to include city names, neighborhoods, or landmarks. For instance, a plumbing company might target searches like "emergency plumber in Dallas", "24-hour plumbing service in Fort Worth", or "best plumber near downtown Dallas." Similarly, specific needs like "pharmacy open late near me" or "restaurant with outdoor seating in Brooklyn" can help you connect with users seeking immediate answers.

Don’t forget regional variations – people in different areas might phrase their queries differently. By tailoring your keywords to reflect these nuances, you can better address the needs of local voice search users.

Expanding Your Current Keyword Lists

Your existing keyword research isn’t outdated – it just needs a conversational upgrade. By adapting your current keywords to better match voice search behavior, you can stay ahead of changing trends.

Start by reviewing mobile query data from Google Search Console. Take high-performing keywords and reframe them as natural, question-based phrases. For example, "SEO strategy guide" could become "How do I create an SEO strategy for my e-commerce website?" Similarly, "backlink analysis" might be transformed into "How can I check my website’s backlinks for free?"

You can also add conversational elements to your keywords. Phrases like "I need to", "Can you tell me", or "What’s the best way to" make your keywords sound more like spoken queries, which aligns them with voice search patterns.

AI tools can provide even more keyword ideas. For instance, you could prompt an AI tool with something like, "Generate 20 questions a small business owner might ask about SEO." This approach often uncovers phrases that resonate with how people naturally speak. Interestingly, AI-generated keywords tend to have higher search volumes and better conversion rates – up to 4.1 times better due to their alignment with user intent.

Another effective method is to focus on problem-solution keywords. For example, ask the AI to list common problems small business owners face with local SEO and how they might search for solutions. This strategy pinpoints the specific challenges driving voice searches, ensuring your keywords address real user needs.

After expanding your keyword list, validate your ideas using tools like SEMrush or Ahrefs. This ensures you’re targeting phrases that are both conversational and backed by solid data.

Lastly, keep in mind that search trends evolve quickly. Around 31% of high-value keywords change significantly in intent or volume every six months. To stay competitive, refresh your voice search keyword strategy at least once a quarter to keep up with these shifts.

Step 3: Analyzing and Organizing Voice Search Keywords

Now that you’ve gathered conversational keywords, it’s time to refine your strategy by analyzing and organizing them. This step ensures your keyword list is optimized for content creation, helping you focus on the terms that matter most.

Evaluating Voice Search Keyword Metrics

Voice search keywords don’t all carry the same weight. To make the most of them, you’ll need to strike a balance between three factors: search volume, keyword difficulty, and how well they align with voice search patterns.

Start by looking at search volume. Bigger numbers aren’t always better. For instance, a keyword like “What’s the best Italian restaurant near downtown Seattle?” might only see 200 searches a month. But those 200 people are likely ready to book a table. Compare that to a broader term like “Italian food,” which might have 50,000 searches but lacks clear intent.

Next, consider keyword difficulty. Voice search results often come from featured snippets – 78% of the time, to be exact. This means you’re competing for the coveted "position zero." Tools like SEMrush and Ahrefs provide difficulty scores that can highlight opportunities where competition is manageable, especially for conversational, question-based phrases.

Finally, evaluate how well a keyword matches natural speech. A term like “emergency plumber services in Dallas, Texas” might have decent metrics but doesn’t sound like something you’d say out loud. On the other hand, “Where can I find an emergency plumber in Dallas?” feels much more natural. Read your keywords aloud to test their voice search relevance.

Focus on keywords that balance solid search volume, moderate difficulty, and high voice relevance. These are the ones most likely to convert, as they capture users when they’re ready to act.

Grouping Keywords by Intent and Topic

Organizing your keywords by intent transforms a scattered list into a clear, actionable plan. Voice search queries generally fall into three categories:

• Informational: These users are looking for answers, like “How do I improve my website’s Google ranking?” or “What are the benefits of local SEO for small businesses?” These keywords work well in blog posts, FAQ sections, and educational content that’s designed to grab featured snippets.
• Navigational: These searchers want specific places or services, such as “digital marketing agency near me” or “SEO services in Austin.” These terms should guide users to your contact page, location information, or service-specific landing pages.
• Transactional: These users are ready to take action. Examples include “How much does SEO cost for a small business?” or “Where can I hire an SEO expert today?” These keywords deserve high-priority, conversion-focused content.

Beyond intent, grouping keywords into topic clusters helps establish what search engines call "topic authority." For example, all your local SEO keywords – like “What is local SEO?”, “local SEO services near me,” and “How much does local SEO cost?” – can be grouped together. This creates a cohesive content strategy that addresses user needs across the board.

You can also take it a step further with semantic clustering, which groups related concepts even if the keywords don’t match exactly. For instance, “Google My Business optimization,” “local citation building,” and “online review management” all naturally fit into the local SEO category. While tools can help with this, you can also do it manually by thinking about how topics connect.

This structured approach makes it easier to weave voice search keywords into your content seamlessly.

Comparing Keyword Research Tools

The tools you choose for keyword research can make a big difference in your voice search strategy. Each tool brings unique strengths, so combining a few often works best.

SEMrush is a powerhouse for detailed analysis, especially with its Keyword Magic Tool, which generates related terms and highlights semantic relationships. Its SERP feature tracking is invaluable for voice search, given the importance of featured snippets.

Ahrefs excels at finding content gaps and identifying question-based opportunities, though you may need to filter results to focus on conversational patterns.

AnswerThePublic is a go-to tool for uncovering natural language queries. Its visual maps are perfect for brainstorming FAQ sections and optimizing for voice search.

For those just starting out, a combination of AnswerThePublic for conversational ideas and SEMrush or Ahrefs for volume and difficulty validation is a solid workflow.

Keep in mind that keyword research isn’t a one-and-done task. User behavior and search trends shift – 31% of high-value keywords change significantly in intent or volume every six months. Refresh your analysis quarterly to stay ahead.

The key isn’t to use every tool out there but to find the ones that provide reliable data, actionable insights, and align with your needs and budget. Start small, master the basics, and expand your toolkit as your strategy evolves.

Step 4: Using Voice Search Keywords in Content

Once you’ve completed your keyword research, it’s time to put those conversational terms to work. The goal is to weave these keywords naturally into your content, ensuring it resonates with both readers and search engines. Keep in mind that 78% of voice search results come from featured snippets, so structuring your content effectively is critical.

Optimizing Content for Featured Snippets

Featured snippets are the prime real estate for voice search. When users ask their smart speakers a question, the response often comes directly from the snippet in position zero. To increase your chances of landing this spot, start with a clear, concise answer. For instance:

"To make waffles at home, mix flour, eggs, milk, baking powder, and butter, then cook in a preheated waffle iron until golden brown."

Use headings that reflect natural queries, like "How do you make waffles from scratch?" instead of generic titles such as "Waffle Recipe Instructions." Organize your content with tools like definition blocks, numbered lists, and bullet points. This structure not only helps search engines extract the most relevant information but also makes it easier for voice assistants to read your content aloud. Aim to answer detailed questions in a way that’s both thorough and easy to understand.

Creating FAQ Sections with Natural Language

FAQ sections are a goldmine for voice search optimization because they align perfectly with the way people speak. When crafting your FAQs, use the same phrasing your audience would. For example, instead of asking, "What are our business hours?" try "What time do you open?" or "When do you close?" Cover the six Ws and H – Who, What, When, Where, Why, and How – to address a wide range of conversational queries.

For example, a local restaurant might include questions like:

• "What’s the most popular dish on your menu?"
• "How late are you open on Saturdays?"

Keep your answers friendly and easy to follow. Avoid using technical jargon or overly formal language; instead, write as if you’re chatting with someone who just asked you a question.

Brooker Webber, Head of Marketing at Ninja Patches, shared that focusing on conversational keywords and answering specific user questions led to a 30% boost in search visibility.

Mobile and Local Optimization Focus

After structuring your content, ensure your website is ready for mobile voice search. Since voice search is often conducted on mobile devices, your site must provide a seamless mobile experience. This means fast load times, responsive design, and intuitive navigation.

Local optimization is equally important, as many voice searches include location-specific intent. Use phrases like "near me", city names, or references to local landmarks in your content naturally. For example, a dental office in Austin, Texas, might target queries like "Best dentist near downtown Austin" or "Where can I find emergency dental care in Austin tonight?"

Leverage schema markup, particularly LocalBusiness schema, to highlight essential details like your address, phone number, hours, and customer reviews. This structured data helps voice assistants quickly pull and present your information. Also, keep your Google Business Profile updated to further enhance your local search visibility.

Voice search optimization is all about adapting to how people naturally speak and delivering quick, helpful answers. By aligning your content with conversational search patterns and focusing on user-friendly structure, you can tap into the growing audience of voice-enabled device users and set the stage for long-term growth.

Conclusion: Key Takeaways for Voice Search Keyword Research

Voice search optimization has become crucial for maintaining digital visibility. With 78% of voice search results coming from featured snippets, businesses must rethink their keyword strategies to stay competitive in this evolving landscape.
