How to conduct consumer research: a complete guide
19 min read
Did you know that Brazilians are among the most demanding consumers in the world? It's no wonder: more and more studies show that customer experience has ceased to be a differentiator and has become a basic expectation. If you've made it this far, you probably already know this and want to go further. You want to understand how to conduct consumer research, truly listen, and transform responses into better decisions.
That's exactly what you'll find here.
But first, why are consumer surveys increasingly on the rise?
The answer lies in changing expectations. Today's consumer doesn't just compare products; they compare experiences. They expect to be recognized, understood, and served consistently in every interaction. When this doesn't happen, when they have to repeat information or receive something generic disguised as personalized, frustration quickly appears.
Recent data from Zendesk CX Trends (2026) reinforce this movement: the vast majority of Brazilians already expect truly personalized experiences and are also bothered when service does not keep up with the context of the conversation.
It is in this scenario that research ceases to be something punctual and becomes strategic. It becomes the most consistent way to understand nuances, identify real expectations, and build experiences that truly make sense.
When to conduct consumer research?
The simplest answer would be: whenever an important decision depends on understanding people. But, in practice, consumer research becomes essential when the brand needs to move beyond assumptions and reduce the risk of making decisions based solely on internal opinion, intuition, or incomplete data.
It can happen before creating a product, to understand needs, pain points, and still underexplored opportunities.
It can also be done during development, to test concepts, messages, prototypes, or functionalities before investing time and money in something that might not make sense to the public.
And it continues to be important after launch, when the brand needs to understand perception, satisfaction, usage barriers, churn, loyalty, and opportunities for improvement.
Consumer research is also fundamental in moments of change: brand repositioning, entry into new markets, sales decline, increase in complaints, campaign launches, journey review, or customer experience transformation.
In these contexts, research helps interpret what is behind behaviors, not just what people do, but why they do it, what they expect, and what they still cannot clearly express.
What types of consumer research are conducted by major brands?
Before delving into the types, an important point: major brands do not research randomly.
They combine different approaches throughout the journey, from initial understanding to continuous optimization, to reduce uncertainties and make more consistent decisions.
There isn't a single type of research that is sufficient; the value lies precisely in their complementarity.
Exploratory research (deep understanding)
This is the starting point when the problem is not yet clear. Here, the objective is not to measure, but to discover. To understand behaviors, motivations, language, and context of use. In-depth interviews, focus groups, and ethnographies are common at this stage.
Major brands use this approach to reveal latent needs, those that consumers often cannot verbalize directly, but which significantly influence decisions.
Descriptive research (measurement and validation)
After exploring, comes the need to quantify. Descriptive research measures the extent of a behavior, validates hypotheses, and provides representativeness.
Surveys, panels, and market studies help answer questions such as “How many people think this way?” or “How much of a priority is this problem?” This is where a company gains the scale and statistical confidence to inform its decisions.
Concept and product testing
Before launching something on the market, brands test it. It can be an idea, a prototype, a functionality, or even a nearly final product.
The objective is to understand acceptance, clarity, relevance, and possible barriers. This type of research avoids investments in solutions that do not solve the real problem or are not well understood by the public.
Customer Experience (CX) research
Focused on the journey, this research monitors consumer perception across touchpoints with the brand. It includes metrics such as satisfaction, effort, and loyalty, as well as qualitative feedback.
It is essential to identify friction, such as confusing processes or disconnected service, and prioritize improvements that directly impact the experience.
Usability testing
Widely used in digital products, they evaluate whether something is easy to use. It observes how people interact with interfaces, where they encounter difficulty, and what prevents them from completing tasks. Brands use these tests recurrently, because small frictions can lead to abandonment and directly impact business results.
Brand tracking research
Here, the focus is on understanding how the brand is perceived over time. It measures attributes such as recall, consideration, trust, and differentiation.
This type of research helps evaluate the impact of campaigns, positioning, and market presence, as well as guiding strategic communication decisions.
Behavior and journey research
Goes beyond what the consumer says, seeking to understand what they do. It analyzes habits, channels, decision moments, and points of influence throughout the journey. It can combine behavioral data (such as analytics) with declared research. It is one of the most robust ways to connect intention and action.
Continuous research (always-on)
Major brands don't just conduct research at specific times. They structure continuous feedback collection systems, monitoring indicators in real time. This allows them to quickly identify behavioral changes and adjust strategies more agilely, without relying solely on isolated studies.
Together, these types form a learning ecosystem. The credibility comes precisely from this combination: exploring to understand, measuring to validate, and testing to evolve.
What are the types of questions for consumer research?
There are several options, but it is important to remember that each one should be applied according to the objective of your research. Let's look at some options:
Open-ended questions (qualitative and exploratory)
Allow the respondent to construct the answer in their own words, without restrictions. They are fundamental for capturing meanings, motivations, and interpretations that do not emerge in structured formats. In robust studies, they are often used to complement closed metrics, helping to explain observed results.
Closed-ended questions (structured and comparable)
Present a defined set of alternatives, ensuring standardization in data collection and facilitating statistical analysis. They are the basis of quantitative research, allowing for the estimation of frequencies, cross-tabulations, and segmentations with greater reliability.
Scale questions (intensity measurement)
They operationalize subjective perceptions into measurable variables. Likert-type scales (e.g., from “strongly disagree” to “strongly agree”) or numerical scales (0 to 10) are widely used to measure attitudes, satisfaction, agreement, and perceived value.
NPS (Net Promoter Score)
Based on a central question, the likelihood of recommending a brand, product, or service, NPS segments respondents into promoters, passives, and detractors. Its strength lies in its simplicity and ability to track loyalty over time, often combined with open-ended questions to understand the reasons behind the score.
CSAT (Customer Satisfaction Score)
Measures the level of satisfaction in relation to a specific interaction, product, or service. Generally applied immediately after a contact or experience, it allows for the identification of friction points more immediately and granularly than broader metrics.
CES (Customer Effort Score)
Focused on the perceived effort by the customer to perform an action (solve a problem, complete a purchase, obtain support). It is based on the principle that experiences with less effort tend to generate greater loyalty. It is especially relevant in service and support journeys.
Behavioral questions (reporting actions)
Investigate what the consumer actually did, rather than what they believe or intend to do. Questions about frequency of use, channels used, or recent decisions tend to have greater predictive validity, as they are based on observed behavior.
Intention questions (future projection)
Explore future dispositions and plans, such as purchase or adoption intent. While useful for indicating trends, they should be interpreted with caution, as there is a known discrepancy between stated intention and actual behavior.
Ranking questions (trade-offs and prioritization)
Ask the respondent to order attributes, benefits, or options. They are particularly useful for understanding decision criteria and value hierarchies, highlighting what actually matters most in the choice.
Dichotomous questions (objective validation)
They offer two mutually exclusive alternatives, such as “yes” or “no”. They are effective for screening and directly validating hypotheses, although they limit the capture of nuance.
Filter questions (sample control)
Used to qualify respondents and direct the flow of the questionnaire. They ensure that only relevant individuals answer certain sections, increasing the accuracy and validity of the results.
Projective questions (access to latent dimensions)
Employ hypothetical scenarios, metaphors, or third-party perspectives to access less conscious or socially sensitive perceptions. They are more common in qualitative approaches and require specialized interpretation.
Together, these different types of questions make up the design of more robust instruments. The credibility of a research lies in the ability to combine formats that capture, simultaneously, interpretive depth and analytical consistency.
How to conduct consumer research?
Researching consumers is, essentially, an exercise in clarity: knowing what you need to learn to make a better decision.
Define the research objective
Every study needs to answer a clear question. Rather than broadly “understanding the consumer”, it should address something specific: why sales fell, what prevents conversion, how to improve the experience, or whether a new proposal makes sense. A clearly defined objective guides all subsequent choices and prevents the collection of irrelevant data.
Choose the appropriate research type
With a clear objective, the approach is defined. If the need is to explore and generate hypotheses, qualitative methods (such as interviews) are more indicated. If the focus is to validate and measure, quantitative methods (surveys) come into play. In many cases, the most robust design combines both: first understand, then measure.
Define the audience (sample)
It is not enough to talk to “customers”. You need to define exactly who should be heard: their profile, behavior, usage context, and stage in the journey. A well-defined sample makes the results more relevant and prevents misleading generalizations.
Structure a good questionnaire or script
Here is one of the most critical points. Questions need to be clear, neutral, and aligned with the objective. Avoid leading questions, technical terms, or ambiguities. Organize the flow logically: start with the context, move on to perception, and deepen when necessary. Fewer questions, more quality.
Choose the collection method
The way you collect directly influences the type of response. Interviews bring depth, but less scale. Online questionnaires allow for volume, but with less nuance. Usability tests observe real behavior. The choice should reflect the type of decision you need to make.
Collect with rigor
During collection, consistency is essential. In qualitative research, this means conducting without interfering or directing responses. In quantitative research, ensuring that the sample follows the defined criteria. Problems at this stage compromise the entire result.
Analyze beyond the surface
Data does not speak for itself. It is necessary to interpret patterns, identify contradictions, and connect responses to the context. In qualitative research, this involves categorizing themes and seeking meanings. In quantitative research, analyzing distributions, cross-tabulations, and differences between segments.
Connect findings to the decision
Research loses value if it is not put into practice. Its results need to answer: “What do we do with this?” Good research provides clear direction, whether to adjust a product, improve a journey, or redefine a strategy.
Continuously validate and refine
Consumers change, contexts evolve. Therefore, research should not be an isolated event, but a continuous process. Major brands structure learning cycles: they test, learn, adjust, and research again.
How to create a questionnaire for consumer research?
It is important to understand that a questionnaire is not just a list of items — it is a measurement instrument. It needs to translate a business objective into clear, neutral, and analyzable questions. A good questionnaire reduces noise, avoids biases, and increases the reliability of decisions.
Start with the objective (what needs to be decided)
Every questionnaire should inform a specific decision. Instead of “understanding the customer”, define exactly what you need to learn: validate a hypothesis, measure satisfaction, identify barriers, or prioritize improvements. This objective guides what is included and, above all, what is left out.
Break down the objective into research questions
Transform the objective into investigable questions. For example: “what are the main choice factors?”, “where are the friction points?”, “how is the product perceived?”. This breakdown acts as a guide to ensure that each question in the questionnaire has a purpose.
Choose the appropriate question type
Not every question should be open-ended, nor should every question be closed-ended. Use open-ended questions to explore and understand the
Use closed-ended questions and scales to measure and compare. Metrics such as Net Promoter Score, Customer Satisfaction Score, and Customer Effort Score can be included when the objective involves experience and satisfaction.
Write clear and neutral questions
Avoid technical, ambiguous, or leading terms. A good question should be understood in the same way by all respondents. Prefer simple, direct, and non-judgmental language. Small word choices can significantly alter results.
Structure a logical flow
The order of questions matters. Start with context and warm-up, move to main topics, and leave more sensitive or complex questions for later. A good flow reduces cognitive effort and improves response quality.
Limit the length (less is more)
Long questionnaires lead to fatigue and less reliable answers. Each question must justify its existence. If it doesn't directly contribute to the objective, it should be removed. Quality outweighs quantity.
Use filter and segmentation questions
Include initial questions to ensure the respondent fits the desired profile. At the end, collect segmentation information (such as profile or behavior) that allows for deeper analysis.
Test before applying (pre-test)
Applying the questionnaire to a small group allows you to identify problems with understanding, flow, or interpretation. This step prevents errors that, once collected at scale, are difficult to correct.
Think about analysis from the start
A common mistake is to build the questionnaire without considering how the data will be analyzed. Before applying, check if the answers will allow for cross-referencing, comparisons, and the extraction of relevant insights.
Review biases and limitations
Assess whether there is leading, order that influences responses, or unbalanced options. No questionnaire is perfect, but recognizing and minimizing biases increases the credibility of the results.
As you can see, creating a good questionnaire is, at its core, an exercise in precision. The more aligned with the objective, the clearer for the respondent, and the more structured for analysis, the greater the value generated by the research.
20 we explain consumer research questions
Below are 20 examples of consumer research questions, organized to cover different objectives, understanding, behavior, experience, and decision. The focus is not just on the question itself, but on the type of insight it allows to generate.

- In what situations do you usually use [product/service]?
- What weighs most heavily on your decision when choosing [category]?
- What problems are you trying to solve when looking for this type of solution?
Real behavior
- When was the last time you used/bought [product]?
- Where do you usually research before making this decision?
- What alternatives have you recently considered?
- What made you choose this option and not another?
Perception and evaluation

- What did you like most about this experience?
- What could have been better?
- If you had to describe [brand/product] in a few words, what would it be?
Experience metrics (standardized)
- On a scale of 0 to 10, how likely are you to recommend our brand to another person? (Net Promoter Score)
- Overall, how satisfied were you with your recent experience? (Customer Satisfaction Score)
- How easy was it to resolve your need with us? (Customer Effort Score)
Barriers and frictions
- Was there any moment when you almost gave up? What happened?
- What would prevent you from using/buying again?
Intention and future
- Do you intend to continue using/buying this type of product? Why?
- What would make you choose another brand in the future?
- If you could change one thing about this experience, what would it be?
How to find consumers for research?
The challenge is not to talk to “many people,” but to the right people to answer your research question. This is what ensures validity and usefulness in the results.
Start by defining who you need to hear from
Recruitment doesn't start with searching, but with defining criteria. Who are these consumers? Current customers, former customers, non-customers, heavy users, beginners? At what point in their journey are they? Without this segmentation, the risk is collecting answers that don't help address the central problem.
Use your own customer base
One of the most valuable, and often underutilized, sources is the internal database: CRM, email list, product users, leads. This audience already has a relationship with the brand and can offer direct insights into real experience. It is especially useful for satisfaction, journey, and product improvement research.
Recruit at journey touchpoints
Websites, applications, transactional emails, and even customer service are strategic channels to invite consumers at the right time. Contextual approaches tend to generate richer responses because they capture the experience close to when it happens.
Utilize research panels
Specialized recruitment platforms (panels) allow access to segmented audiences quickly and scalably. They are useful when you need volume or specific profiles that are not in your database. They require attention to sample quality and selection criteria.
Social media and communities
Groups, forums, and social media can be relevant sources, especially for specific niches. Here, the caution is to avoid biases—more engaged people tend to respond more—and ensure that the recruited profile aligns with the research audience.
Active recruitment (interception)
Approaching consumers in context, whether in a physical environment (stores, events) or digital, allows for capturing real experiences. It is a common approach in usability testing and journey research, as it reduces the distance between experience and report.
Incentives and engagement
Depending on the profile and complexity of the research, offering incentives (financial or otherwise) can increase participation and response quality. The critical point is balance: the incentive should motivate participation, but not attract people uninterested in the topic.
Rigorous screening
Not every interested person is a good participant. Screening questions help ensure that the respondent truly fits the desired profile. This filter is essential to maintain sample consistency and avoid distortions in the results.
Quality over quantity
More answers do not mean better answers. In many cases, a well-selected and coherent sample generates more reliable insights than large volumes of unqualified data.
Build a continuous process
Large organizations do not recruit from scratch for every research project. They build their own participant bases (proprietary panels), creating a recurring channel for listening to consumers who have already agreed to participate in future studies.
Main mistakes in consumer research (that you should avoid)
Most problems in research are not in the tool, but in the decisions made throughout the process. Small errors in definition, design, or interpretation tend to generate distorted conclusions and, consequently, misguided decisions.
Starting without a clear question
Generic research produces generic answers. When the objective is not well defined, the study becomes a collection of scattered opinions, without real capacity to guide decisions. Lack of focus is one of the most common and most expensive mistakes.
Find consumers for your research
Talking to the wrong audience
Listening to people outside the necessary profile compromises the validity of the results. Mixing distinct profiles, without control, leads to conclusions that do not truly represent anyone. Correctly defining the sample is as important as the questionnaire.
Asking biased questions
Questions that induce answers, whether by form, tone, or order, distort the data. Suggestive terms, unbalanced alternatives, or poorly presented contexts cause the respondent to “follow” the researcher's expectation, instead of expressing their own perception.
Confusing opinion with behavior
What people say does not always correspond to what they do. Basing decisions solely on declarations (intention, preference) without considering real behavior can lead to fragile conclusions. Whenever possible, it is necessary to cross-reference discourse with action.
Over-reliance on a single source
Depending on a single method, metric, or study limits understanding. For example, using only one satisfaction metric without investigating the context can hide relevant problems. Robust research combines approaches to reduce biases.
Long and poorly structured questionnaires
Extensive or confusing surveys generate fatigue, superficial answers, and abandonment. Furthermore, a poorly planned order can influence subsequent responses. Clarity, objectivity, and logical flow are essential to maintain data quality.
Ignoring the context of the response
Analyzing responses out of the context in which they were given can lead to mistaken interpretations. The same behavior can have different motivations depending on the moment, channel, or consumer profile.
Over-interpreting results
Finding patterns where none exist, or drawing broad conclusions from limited data, is a recurring mistake. Not every result is significant, and not every difference is relevant to the business. Analytical rigor is essential.
Not connecting research to decision
Collecting data without a clear plan for use turns research into an academic exercise disconnected from reality. The value lies in the application: what changes based on this insight?
Treating research as an event, not a process
Conducting isolated studies, without continuity, makes it difficult to track changes and learn over time. Consumers evolve, contexts change, and research needs to keep up with this movement.
Ignoring limitations and biases
Every research has limitations: sample, method, context. Not acknowledging them creates a false sense of certainty. Experienced researchers make it clear how far the data allows them to go and where uncertainty begins.
Consumer research panel: is it worth it?
First of all, the direct answer: yes, consumer research panels are worth it, especially when the goal is to gain speed, consistency, and qualified access to specific profiles.
When well-structured, a panel is not just a base of respondents, but a strategic research asset. It allows the company to move from ad hoc recruitment to operating with a continuous flow of learning.
Why is it worth investing in a panel?
The main advantage is agility. Instead of starting recruitment from scratch for each study, you already have access to previously qualified people, which reduces time and field costs.
Another relevant point is segmentation. Panels allow access to specific profiles with greater precision, whether by behavior, demographics, or consumption habits, which increases the quality of insights and reduces noise in the analysis.
There is also an important gain in consistency. With a panel, it is possible to track changes over time, repeat studies, continuously test hypotheses, and build a more robust view of the consumer.
Furthermore, well-managed panels include validation and quality control processes, which helps avoid inconsistent responses or unengaged participants.
When does a panel make more sense?
Panels are especially useful when there is a recurring need for research, whether for concept testing, campaign validation, experience tracking, or continuous consumer understanding.
They also make sense when the audience is hard to find or when response speed is a critical factor for the business.
Here's a tip: PainelTap was structured precisely with this objective: to connect companies with real consumers, with clear segmentation criteria and a focus on response quality. The proposal is not just to deliver volume, but to ensure you speak with the right people, at the right time, to answer relevant business questions.
