What is On-site intercept survey?
An on-site intercept survey is a short questionnaire given to people while they are physically present at a location relevant to the survey topic. It's designed to capture immediate feedback by approaching people where they are — in stores, at events, transport hubs, clinics or community centres.
An on-site intercept survey (sometimes called an intercept or in-person intercept) involves briefly stopping visitors at a place of activity and asking them to complete a short survey on the spot. Intercepts are typically brief (often 3–10 questions) and can be run on tablets, kiosks, paper forms or via a QR code that opens a mobile survey. The goal is to collect timely, context-rich responses from people directly experiencing a service, event or environment. Because responses are collected in the moment, intercepts reduce recall bias and often yield higher immediate response rates than email or postal surveys. They do, however, require on-location staffing or signage and can be influenced by who is present at the time (sampling bias) and by social desirability effects.
Usage example
A local council runs an on-site intercept survey at a weekend community market using tablets and QR codes. Staff invite visitors to answer three quick questions about market cleanliness and accessibility; participants choose their preferred language on the tablet and the council receives translated responses for analysis.
Practical application
On-site intercept surveys matter because they let you hear from people in the moment — when impressions are fresh and context is clear. They’re useful for testing new layouts, collecting event feedback, measuring satisfaction at points of service (e.g., reception desks, clinics or transit stops) and uncovering barriers people face in specific environments. For multilingual communities, running an intercept with a language-enabled survey removes a major participation barrier: participants can respond in their preferred language on the spot, and administrators can read translated responses later. Intercepts are best used for short, focused questions and when you need rapid, actionable insight rather than statistically representative samples.
FAQ
How long should an on-site intercept survey be?
Keep it short — typically 3–10 questions that take 1–5 minutes. The quicker the survey, the higher the completion rate on-site. Focus on a few clear, actionable questions rather than a long questionnaire.
What devices or methods work best for intercepts?
Tablets and kiosks work well when staff are present. QR codes or short URLs let people use their own phones without staffing. Paper can work as a backup but adds data-entry work. Choose the method that fits your setting, footfall and available staff.
How do intercepts avoid excluding non-English speakers?
Offer the survey in multiple languages at the point of contact. Use a language-selection option on the device or QR destination, display clear signage in key languages, and train staff to point people to language options. With an integrated multilingual platform, participants see the survey in their language and administrators receive translated responses for review.
Are intercept surveys statistically representative?
Not necessarily. Intercepts capture people present at a specific place and time, so results reflect that subset of visitors. They’re excellent for quick, contextual feedback and identifying common issues, but you should be cautious about generalising findings to an entire population without complementary sampling methods.
