Whether you’re running exploratory research, measuring customer satisfaction, or tracking behavioral changes over time, this post has you covered.
Importance of data in survey research
Data is the foundation of strategic decisions, and survey research has emerged as a cornerstone of modern inquiry. Businesses use it to refine marketing strategies, governments rely on it to understand public sentiment, and educators leverage it to improve teaching methods. With the proliferation of online tools and data analytics platforms, conducting surveys has never been easier—or more powerful.
However, the growing ease of access also brings challenges. Poorly designed surveys can lead to misleading insights, low response rates, and biased data. That’s why it’s more important than ever to select the right type of survey tailored to your specific goals and audience.
But not all surveys are created equal. In fact, survey research can be broken down into various types—each suited for different goals, data collection methods, and research designs. Knowing which type to use helps ensure your survey is effective, valid, and yields actionable insights.
Types of survey research by purpose
Understanding the purpose behind your survey is the first step in choosing the right methodology. There are three primary types of survey research by purpose:
Exploratory survey research
Exploratory surveys are conducted when little is known about a topic. Their goal is to uncover patterns, generate hypotheses, or gain deeper understanding—not necessarily to produce statistically significant results.
Best for: Early-stage research, new markets, or unfamiliar problems.
Example: Open-ended employee feedback survey on remote work challenges.
Common format: Qualitative, open-ended questions.
These surveys often serve as a foundation for future research efforts. Since they aim to explore rather than measure, they rely heavily on open-ended questions that invite participants to share detailed thoughts, concerns, and experiences. Exploratory surveys are especially useful for identifying pain points, spotting trends, or shaping product development strategies. They’re also a powerful tool for refining survey questions before investing in a larger quantitative study.
Use Case: A nonprofit organization conducts an exploratory survey to learn what motivates community members to volunteer for environmental cleanups.
Tip: Use exploratory surveys in the brainstorming phase of program development.
Descriptive survey research
Descriptive surveys aim to provide an accurate representation of a population’s characteristics, behaviors, or opinions. These are the most commonly used survey types in both academic and commercial research.
Best for: Measuring customer satisfaction, tracking habits, or collecting demographic data.
Example: A company wants to determine the percentage of users who prefer mobile over desktop.
Common format: Closed-ended questions, Likert scales, demographic fields.
This type of research focuses on the ‘what’—what people think, feel, do, or prefer. While it doesn’t delve into why those behaviors occur, it provides a data-driven foundation for identifying patterns and making informed decisions. Descriptive surveys are ideal for producing dashboards, infographics, or reports that provide stakeholders with a clear understanding of the current state of affairs.
Use Case: A retail chain conducts descriptive surveys quarterly to track customer satisfaction across its various locations.
Causal survey research (explanatory)
Causal research investigates cause-and-effect relationships. These surveys often include experiments, A/B testing, or other controlled conditions.
Best for: Validating hypotheses, testing marketing campaigns, or assessing behavioral change.
Example: Survey A tests a new website layout and compares the results with those of Survey B (the old layout).
Common format: Controlled variables, random assignment, pre/post surveys.
Unlike exploratory or descriptive surveys, causal research focuses on understanding why something happens. This often requires isolating variables and manipulating one while holding others constant to observe the outcome. Though complex and more resource-intensive, causal surveys offer valuable insights into what actions drive specific behaviors—making them especially useful in UX testing, advertising research, and behavioral science.
Tip: For effective causal research, consider collaborating with a statistician to ensure your study controls for confounding variables.
Types of survey research by data collection method
Once you’ve determined your research purpose, the next consideration is how you’ll collect your data. Here are the main types of survey research based on data collection methods:
Online surveys
Online surveys are among the most popular and cost-effective survey methods today. They are distributed via email, websites, social media, or survey platforms like SurveyPlanet.
Best for: Large-scale data collection, customer satisfaction, quick feedback.
Pros: Cost-effective, fast, easy to analyze.
Cons: Limited to populations with internet access; lower response quality if poorly designed.
These surveys are easy to distribute and scale, making them ideal for reaching large or geographically dispersed audiences. Tools like SurveyPlanet also offer features such as skip logic, themes, and analytics, making survey creation and analysis much easier.
Use Case: A software company uses an online survey to gather user feedback after launching a new feature.
AI-powered surveys
AI-powered surveys are an emerging and increasingly sophisticated type of online survey. While they share the same digital delivery methods—such as web, mobile apps, or email—they go a step further by using artificial intelligence to personalize the survey experience in real-time. AI can adapt questions based on previous answers, analyze open-ended responses instantly using natural language processing, and even simulate human-like conversations through chatbots. This not only increases respondent engagement but also improves the quality and depth of the data collected.
Use Case: A travel company uses an AI chatbot survey on its website to ask visitors about their destination preferences and travel habits, then tailors follow-up questions and offers based on each response.
Telephone surveys
Telephone surveys involve calling participants to ask them questions directly. While more costly than online surveys, they can result in higher-quality responses, especially when targeting specific demographics.
Best for: Older populations, in-depth responses, or complex topics.
Pros: Higher engagement, can clarify confusing questions in real time.
Cons: Time-consuming, expensive, risk of bias from interviewer tone.
Use Case: A healthcare provider uses telephone surveys to follow up with patients after treatment to assess satisfaction and outcomes.
Face-to-face surveys
These are conducted in person, often in a controlled environment like a lab, store, or public place. This method is ideal for complex or sensitive topics.
Best for: Medical or psychological research, product testing, or in-depth interviews.
Pros: Highest response quality, interviewer can observe body language.
Cons: Time-intensive, expensive, and less scalable.
Use Case: A consumer goods brand tests a new product in stores and gathers feedback through face-to-face interviews.
Mail surveys
Mail surveys are sent and returned via postal services. While declining in popularity, they still have a role in reaching populations without internet access or in areas where digital tools are less trusted.
Best for: Rural or older populations, government surveys.
Pros: High accessibility, tangible format, anonymity.
Cons: Slow turnaround, low response rates, printing and postage costs.
Use Case: A local government sends mail surveys to residents to assess satisfaction with public services.
Types of survey research by design
Survey design affects everything from how questions are structured to how results are interpreted. Here are the main types of survey design:
Cross-sectional surveys
Cross-sectional surveys collect data at a single point in time. They’re like a snapshot that captures what’s happening in a population right now.
Best for: One-time studies, customer feedback, political polling.
Pros: Quick, relatively simple to analyze, cost-effective.
Cons: Doesn’t capture changes over time.
Use Case: A brand launches a campaign and immediately surveys users to measure initial reactions.
Longitudinal surveys
Longitudinal surveys collect data from the same subjects over a long period. This method is often used to detect trends, measure long-term effects, or monitor behavioral change.
Best for: Tracking customer loyalty, employee engagement, or academic studies.
Pros: Rich insights into changes over time.
Cons: Expensive, prone to participant dropout, requires long-term planning.
Use Case: An educational researcher surveys the same group of students annually to track their academic progress.
Retrospective surveys
Retrospective surveys ask participants to reflect on past events or experiences. They are used to study long-term outcomes or recall-based data.
Best for: Healthcare research, customer journey analysis.
Pros: Useful when historical data isn’t available.
Cons: Relies on memory, potential for recall bias.
Use Case: A marketing team surveys long-time customers to understand the factors that influenced their initial decision to make a purchase.
Additional types of survey research
Last but not least, here are a few additional survey research types that extend your options beyond the traditional categories that you might find helpful.
Omnibus surveys
Omnibus surveys combine questions from multiple organizations into one survey administered to a shared sample. Clients pay only for the questions they include.
Best for: Quick market snapshots, PR testing, media insights.
Example: A beverage company adds two branding questions to a broader consumer trends survey.
Common format: A mix of short multiple-choice and scaled questions.
Omnibus surveys are budget-friendly for businesses that want to gather limited data from a large audience without funding a full-scale survey.
Use Case: A PR agency tests brand recall for a new campaign using one question in a national omnibus survey.
Tip: Use omnibus surveys when you need quick directional data without deep segmentation.
Deliberative surveys
Deliberative surveys give respondents background information on an issue, allow for reflection or group discussion, and then collect responses.
Best for: Civic engagement, policy research, community decision-making.
Example: A municipality briefs citizens on the trade-offs of different waste management solutions before surveying them.
Common format: Pre-survey, information session, post-survey.
They offer deeper insight into informed opinions but require significant facilitation and neutrality.
Use Case: A university conducts a deliberative survey with students on tuition changes after sharing financial data and options.
Tip: Use expert facilitators to maintain objectivity during the educational phase.
Intercept surveys
Intercept surveys are conducted in the moment, often in physical locations or during online sessions, to capture immediate feedback.
Best for: Customer experience, event feedback, usability testing.
Example: Shoppers are asked one or two questions upon exiting a retail store.
Common format: Brief, often one to five questions, verbal or digital.
Their real-time nature captures fresh, context-specific opinions but limits depth due to brevity.
Use Case: A website triggers a one-question survey for users abandoning their shopping cart.
Tip: Keep questions concise and relevant to the immediate context.
