Every day, people tell search engines what they need, what worries them and what they want to buy. They use their own words, at the moment the need appears, and nobody has to ask them. That makes search data one of the clearest signals a business can study when it is looking for its next opportunity.
The scale is hard to ignore. In early 2025, Google said it handles more than 5 trillion searches a year, which works out to roughly 13.7 billion a day. Google has also said that about 15% of the searches it sees each day are completely new. Customers keep asking questions, and some of those questions point to products, services and content that do not exist yet.
But search data is a clue, not an answer. It shows what people look for. It does not explain why they look, or whether they will pay. This guide shows how to use it well: what to look for, which tools to use, where the numbers can mislead you, and how to turn findings into real business decisions.
Key Takeaways
- Search data shows what customers want in their own words, but it works best when combined with interviews, surveys and sales data.
- The best research is current, uses more than one source, studies real behavior and is tied to a decision you need to make.
- Competitors you do not track (indirect rivals, substitutes and new entrants) can matter as much as the ones you do.
- Gaps show up where people ask questions that nobody answers well, or complain about what already exists.
- Google Trends does not show exact search counts, and Keyword Planner shows only volume ranges for accounts with little or no ad spend. Read both as signals, not facts.
- Start with the decision you must make, then pick the data that helps you make it.
Why Businesses Need Better Market Research
Market research reduces guesswork. The problem is that a lot of research is slow, outdated or based on a single source. Better research fixes that, and search data can be one part of it.
Old research is a guess in disguise
Market research answers a question at one moment in time. After that, competitors launch products, rules change and customer priorities shift. Valona, a market intelligence company, argues that keeping research up to date helps teams adjust strategy early and avoid costly mistakes. Guidance for small businesses says the same thing: the U.S. Chamber of Commerce’s CO— lists relying on outdated data and treating analysis as a one-time exercise among the most common mistakes.
For competitor research, guides often suggest a refresh every quarter in fast-moving markets and about twice a year in steadier ones. Attest recommends repeating a full market opportunity analysis every 6 to 12 months.
Buyers now do much of the research themselves
Gartner surveyed 632 B2B buyers in August and September 2024 and found that 61% prefer an overall buying experience without a sales rep. Most said they prefer to do independent research through digital channels. Gartner also found that buyers still want a seller’s input for tasks that need judgment, such as deciding whether a product fits their company’s needs.
What does this mean for you? By the time a buyer contacts you, they have often already formed opinions. The questions they typed into a search box, and the answers they found, shaped those opinions. Studying that stage of the journey is no longer optional.
Guessing what customers want can backfire
Gartner surveyed 1,464 business buyers and consumers in North America, the U.K., Australia and New Zealand in November and December 2024 about personalized marketing. It found that 53% reported negative experiences with it. Those customers were 3.2 times more likely to regret a purchase and 44% less likely to purchase again.
Gartner’s warning is aimed at passive personalization tactics, which do not involve the customer. Customers engaged through active personalization, where they share context and preferences, were 2.3 times more likely to feel confident completing key purchase decisions. The lesson for research is simple: tailoring messages without a real understanding of what the customer is trying to do can hurt trust.
Customers do not always say what they need
Customers can name some problems easily. Others they have not recognized themselves, so they never ask for a fix. Watching how people behave, asking open questions and trying the experience yourself all help you find these hidden needs.
Search data helps with the first of these steps. It lets you see what people actually look for without prompting. But it mostly reveals needs that people can put into words. Hidden needs usually need observation and interviews as well.
Why it matters for profit
A well-known 1990 Harvard Business Review article, “Zero Defections: Quality Comes to Services” by Frederick Reichheld and W. Earl Sasser, reported that reducing customer defections by 5% could raise profits by 25% to 85%, depending on the company and industry. Later critics note that the effect depends on starting margins and on whether the customers you keep are profitable, so treat the range as an illustration, not a promise. Even so, understanding why customers stay or leave remains one of the best uses of research.
What “better” research looks like
Five traits describe good research across the sources reviewed for this guide:
- Current: it is refreshed on a schedule, not done once.
- Multi-source: it combines search data, surveys, interviews and sales records.
- Behavior-based: it studies what people do, not only what they say.
- Decision-led: it starts with a specific business question.
- Acted on: findings turn into changes, then get measured.
Search tools can be low-cost. Google Trends, for example, is free and appears on the list of free market research resources from CO— by the U.S. Chamber of Commerce. That makes it a sensible place to start.
Finding Competitors That Traditional Research Misses
Most businesses can name the few rivals they face every day. The danger is the competitor you never thought to name. A wider view of competition, supported by search data, helps you find them.
Look beyond your own category
Qualtrics warns that companies who watch only their category competitors can miss a category disruptor or a business that redefines the category. Step back from time to time, look at wider industry trends, and ask people who have left your category what they chose instead.
Qualtrics also sorts competitors into four groups:
- Direct competitors sell like-for-like products or services in your sector or area. A garden center’s direct competitors are the other garden centers nearby.
- Indirect competitors meet the same customer need in a different way. A supermarket can be an indirect competitor to a garden center.
- Substitute competitors do not sell the same thing but compete for the same spending. A cinema and a streaming service, for example, compete for the same evening and the same entertainment budget.
- New entrants have recently arrived with similar products or services.
Think in jobs, not products
The “jobs to be done” idea, associated with Clayton Christensen and Tony Ulwick (who describe it differently), says people do not just buy products. They hire them to do a job. In Christensen’s best-known example, a fast-food chain wanted to sell more milkshakes. Researchers found that many morning buyers wanted something to keep them full and occupied during a long, dull commute. That meant the shake competed with bagels and doughnuts, not only with other milkshakes.
The lesson for search research is simple. Describe the job your customer is trying to do, then see who else shows up when they search for it.
Use search to spot hidden rivals
Here are practical ways to do it:
- Search for the problem, not your product. Type the problem the way a customer would. Notice which brands, apps, forums and guides appear. Those are your real rivals for attention.
- Look at comparison searches. Searches such as “alternative to” followed by a competitor’s name can show customers who are open to switching.
- Check which keywords rivals rank for. SEO tools such as Ahrefs, Semrush and Similarweb can show this.
- Read review sites. Customer reviews of competing products on sites like G2, Capterra and TrustRadius often reveal needs that nobody is meeting.
- Ask customers directly. A simple question such as “What else did you consider before choosing us?” surfaces informal alternatives that no tool will show you.
Measure your share of search
Les Binet, an effectiveness expert, presented the idea of “share of search” at the IPA’s EffWorks Global 2020 conference on 14 October 2020. It is your brand’s share of all searches for brands in your category. If people search for your brand 5,000 times and for two rivals 3,000 and 2,000 times, your share of search is 50%.
Binet tested it in three categories: cars, energy and mobile phone handsets. In all three, share of search correlated with market share, and in his analysis it tended to lead it. The lead time differed by category: up to about a year for cars, about six months for handsets and zero to three months for energy.
Two cautions apply. First, three categories is a small test, so do not assume the pattern holds everywhere. Second, the link works in both directions, because people who already own a product tend to search for it too. Use share of search as an early warning sign, then check it against sales data.
Identifying Customer Interests Through Search Results
Search results show more than keywords. They show what people want to do, what kind of answer they expect and what they worry about next.
Learn the four types of search intent
Searchers usually fall into four groups:
- Informational: people want to learn, with words like how, why, guide or tips.
- Navigational: people want a specific brand or site.
- Commercial: people compare options, with words like best, review or alternatives.
- Transactional: people are ready to act, with words like buy, price, order or near me.
Each type points to a different opportunity. Many informational searches suggest an audience still learning, which is a chance to educate. Commercial searches show people weighing choices, which tells you where to stand out. Transactional searches show demand that is close to a purchase.
Read the results page, not just the keyword
If someone searches “marketing software,” look at what the results page shows. If most results are product pages, people probably want to buy or compare. If most are explainers, they probably want to learn first. The mix of results tells you what searchers expect.
Also check the related searches and “People also ask” boxes. They show follow-up questions and worries that a single keyword hides.
Use Google Trends for direction
Google Trends lets you compare interest in terms over time, spot seasonal patterns and see related queries and topics. It is free, which makes it a good first stop. Its data goes back to 2004. For long date ranges it shows monthly points, while shorter ranges show weekly or daily detail, so compare several time windows before you draw a conclusion.
Know what the numbers really mean
Neither of the two most popular free tools gives exact counts, and that matters when you interpret them:
- Google Trends shows a score from 0 to 100, scaled against the highest point of interest for the terms and period you chose. It is not a search count. The score changes when you change the time range, and Google Trends uses a sample of data rather than all searches. Very low-volume terms may show nothing at all.
- Google Keyword Planner shows volume ranges, such as 1K to 10K, for accounts with little or no active ad spend. Ranges are fine for rough sizing but poor for choosing between two similar keywords.
So treat both as direction-finders. Compare terms with each other and watch the trend, rather than quoting a single number as fact.
Watch the AI summary effect
Search pages are changing. A Pew Research Center analysis of the browsing of 900 U.S. adults in March 2025, covering 68,879 searches, found that people clicked a regular result in 8% of visits when Google showed an AI summary, compared with 15% when it did not. Only about 1% of visits led to a click on a link inside the summary. About 18% of the searches in the sample showed an AI summary. Google has pushed back on the study’s methods.
Later data points the same way. SparkToro, using Similarweb clickstream data, reported that 68.01% of U.S. Google searches between January and April 2026 ended without a click, up from 60.45% in 2024. Third-party trackers in 2026 also generally report AI summaries on a larger share of queries than Pew’s 2025 sample did, but their figures differ widely, so check your own priority queries instead of relying on one average.
What does this mean for you? What people type is still a valuable signal of demand. But traffic to your own site is becoming a weaker measure of interest. Look at impressions and queries in Google Search Console as well.
Spotting Product and Content Gaps
A gap is a need that people have and nobody serves well. Gaps can be missing products, missing features or missing answers.
Start with a frustration
Many successful companies began with a personal annoyance. Dave Gilboa lost his glasses on a backpacking trip and learned that a replacement would cost about $700, while a new phone cost around $200. He asked friends why glasses were so expensive. Together with Neil Blumenthal, Andy Hunt and Jeff Raider, fellow students at the Wharton School, he explored the problem. That frustration became Warby Parker, which launched in 2010 selling glasses online for $95.
The lesson is that a repeated complaint is a market signal. Search data lets you check whether other people share it.
Product gaps: what to look for
- Repeated complaints. Read negative reviews of your own and competing products. The same complaint appearing again and again points to an unmet need.
- Searches that show dissatisfaction. Phrases like “alternative to,” “cheaper,” “not working” or “problems with” often signal unhappy customers.
- When people build spreadsheets or stitch tools together, the existing product is not finishing the job.
- Overlooked groups. Clayton Christensen of Harvard Business School describes two openings that smaller companies use. Low-end disruption targets overserved customers at the bottom of a market who do not want to pay for premium features. New-market disruption serves non-consumers, people who were left out of the market because the product was too expensive or too hard to use. Searches for “simple,” “basic” or “budget” versions of a product may hint at the first group, and searches such as “affordable” or “for beginners” may hint at the second, but treat these as clues, not proof.
- Slow or exclusive processes. Ask whether a process could be faster, cheaper or more accessible to people it currently leaves out.
Content gaps: what to look for
A content gap is a topic or question your audience searches for that your site does not answer.
- Keyword gap tools. Tools like Semrush and Ahrefs can show terms your competitors rank for and you do not.
- Your own site search. What visitors type into your search bar, especially searches that return no results, shows missing products or pages.
- Customer journey checks. Review whether your content only answers early questions and ignores setup, troubleshooting and after-sale needs.
- Questions in the results. If the “People also ask” questions for your topic have weak answers, you have an opening.
Confirm before you build
Do not build on a single signal. A correlation does not prove that one thing causes another, so validate important findings before major decisions. A small test, such as a simple landing page or short interviews with real customers, can show whether interest turns into action.
Tracking Changes Across Different Markets
A trend in one country does not always hold in another. A global category trend can hide big differences between markets, such as one market caring about premium features and another caring about price.
Set a clear baseline
Choose a few consistent measures and use them in every market. Examples include search interest in your main terms, branded search share and the questions people ask. Consistency lets you compare real change instead of noise.
Compare carefully across regions
Google Trends regional values show a term’s share of searches in each region, scaled so that the top region scores 100. A small country can therefore score higher than a large one even though far fewer people there are searching. Use regional views to see where interest is strong relative to local search activity, then confirm with sales data, local market statistics or Search Console.
Also search in the local language. People in different countries often use different words for the same need. Seer Interactive, a digital marketing agency, describes using international search-volume data to compare which regions look strongest for expansion.
Look at the questions, not just the volume
Compare what people look for in each market. In one place, searches may focus on affordability. In another, they may focus on availability or features. These differences affect where to launch, what to emphasize and what to build first.
Separate a real shift from a blip
Look at several years of data, not a few weeks. Check seasonality so you can time launches and stock. Then ask whether a change is a lasting shift or a short spike. Movement in search alone does not prove that a campaign caused it, so read it alongside other evidence.
Check the rest of your data too
Free public data can help you cross-check. The CO— guide lists the U.S. Census Bureau, the Bureau of Labor Statistics, Data.gov, state commerce sites and the Pew Research Center as free starting points.
Turning Search Findings into Business Decisions
Findings only matter if they change what you do. Start with the decision, not the data.
Start with the question
Bernard Marr, a data strategy author, says you should not start a data project until you know which business question it should answer. He recommends linking each project to strategic priorities and to business KPIs that measure success. Before you open any tool, write down:
- What is the objective?
- How will we measure success?
- What data do we need?
- Who will use the results?
- Who owns the project?
- Are there privacy or legal rules to follow?
Start with a small number of projects, a mix of quick wins and bigger ones. Quick wins show value fast and build support.
Match the decision to the evidence
Here is a simple way to connect common decisions with search-based evidence:
- Should we launch this product? Look at whether interest is growing over several years, which questions people ask and how well existing results answer them.
- Which market should we enter first? Compare relative interest and the questions asked in each market, then check with sales or market statistics.
- What should our message say? Use the exact words customers type, and the worries they raise, in your headlines and product pages. For outbound emails, sales engagement software can show which wording gets replies.
- What should we name it? Use the words people actually use when they search for the product.
- What content should we create? Fill the questions with weak answers first.
Size the opportunity
The CO— guide explains three market size measures:
- Total addressable market (TAM): the total revenue opportunity if every potential customer buys, such as every coffee drinker in the United States.
- Serviceable addressable market (SAM): the part of the TAM you can realistically serve based on geography or product offering, such as coffee drinkers in one city who want specialty coffee.
- Serviceable obtainable market (SOM): the share of the SAM you can realistically win in the near term.
Search interest can give a rough sense of online demand at the top of this funnel. It should be backed by population, spending and competitor data before you rely on it.
Score and rank your options
Once you have a list of opportunities, rank them. An impact-effort matrix sorts ideas by how much they could help and how hard they are to do. Do high-impact, low-effort ideas first. You can also score each opportunity on demand, growth, competition and how well it fits your strengths.
Test, measure and repeat
The CO— guide gives a hypothetical example of the full loop. A person starting a neighborhood pet grooming business checks Census Bureau data on pet households, reviews local competitors’ prices, reviews and appointment availability, and interviews customers. The interviews show that many pet owners struggle to book evening and weekend appointments, so the business plans extended hours and online scheduling and prices competitively.
After you act, measure the result and feed it back into your next round of research. Attest recommends repeating a full opportunity analysis every 6 to 12 months, since new competitors, technologies and customer needs keep appearing.
Choosing the Right Data Sources for Ongoing Research
No single source tells you everything. Choosing the right mix is part of good research.
Why one source is not enough
Search data shows what people look for, but not everything that shaped the decision. A purchase can start with a store visit, a friend’s advice or an ad that never involved a search. A search-only view would miss those steps, which is why each business question needs the source that fits it.
Match the source to the question
Choose methods based on your objective and on practical limits such as budget, time and the accuracy you need. Here is a simple guide:
- What are people interested in, and is it growing? Start with Google Trends, then check Keyword Planner ranges and third-party SEO tools for volume estimates, remembering that estimates differ between tools.
- What do people look for on my own site, and what do they reach me through? Use Google Search Console and your internal site search. These show real queries and impressions for your own property.
- Why do people want this, and what do they feel? Use interviews, surveys and focus groups. Qualitative methods explain the “why” behind the numbers.
- How big is the market, and where is it? Use government statistics and industry reports, plus search volume as a rough signal.
- Who are the competitors, and how do customers see them? Use competitor tools, review sites and social listening, plus customer questions.
- Did our action work? Use your sales, CRM and analytics data.
Collecting search results at scale. Checking a few keywords by hand works at first, but it gets slow once you track dozens of terms across several markets. At that point, many teams use a web search API to collect search results programmatically. These services return results as structured data, such as JSON, so a script can log rankings, related questions and result types on a schedule. Some providers, including SERPHouse, support results localized by country and language, which helps when you compare markets. Results pulled this way can differ from what a signed-in person sees, so record the date, location and tool for each pull, and check the provider’s terms and local data rules before you collect anything.
Combine and cross-check
Mix quantitative data (such as surveys and analytics) with qualitative data (such as interviews). When two sources disagree, find the cause. It could be different methods, different samples or a real change in behavior. Check the conflict against a third source instead of ignoring it.
Keep your data clean and lawful
Bad data leads to bad conclusions, so remove duplicates, fix errors and use consistent formats before you analyze. Handle customer data with care. If you use personal data, follow rules such as the GDPR. Its higher penalty tier allows fines of up to €20 million or 4% of global annual turnover, whichever is higher. The lower tier allows up to €10 million or 2%. Check with your legal or privacy adviser on what applies to you.
Build a simple routine
- Pick two or three questions that matter most this quarter.
- Choose one search source, one customer source and one business source for each.
- Record the date and tool for every number, so you can refresh it later.
- Review on a set schedule. Competitor research can be refreshed quarterly or twice a year, depending on how fast your market moves, and a full opportunity analysis every 6 to 12 months.
FAQs
What is search data in market research?
Search data is information about what people type into search engines, such as how often they search a term, how that changes over time and which related questions they ask. It shows what people want in their own words.
Is Google Trends accurate enough for business decisions?
It is good for direction, comparison and seasonality. It does not show exact search counts, because it scales results from 0 to 100 and uses a sample of data. Confirm important decisions with other sources.
Can search data replace surveys and interviews?
No. Search data shows what people look for, but not why, and it does not show whether they will pay. Interviews and surveys explain motives and test willingness to buy.
How often should I review my market research?
Competitor research can be refreshed quarterly or twice a year, and a full market opportunity analysis every 6 to 12 months. Check search trends more often if your market moves fast.
What is the share of search?
Share of search is your brand’s share of all searches for brands in your category. Les Binet’s research found that it correlated with market share in three categories and tended to move ahead of it, so it can work as an early warning signal.
Conclusion
Search data gives businesses a direct view of what people want, worry about and compare, in the words they choose. Used well, it helps you find competitors you were missing, see which questions go unanswered, compare markets, and test ideas cheaply before investing.
Its limits matter just as much. Tool numbers are estimates or relative scores, AI summaries are changing how people click, and a search shows interest, not willingness to pay. So pair search data with interviews, surveys and sales records, and start every project with the decision you need to make.
A good first step is small. Pick one question, such as “Is interest in this product growing, and what are people asking about it?” Check it in Google Trends, read the results page, then talk to five real customers. You will learn more from that than from a guess.
