What is a Mobile Survey? Definition, Examples & Best Practices

A mobile survey is a questionnaire designed to function well on smartphones and tablets. This means layouts that adapt to small screens, question formats that work with touch input, limited scrolling, and a length suited to mobile attention spans.

ESOMAR's Global Market Research report (2023) estimates that over 55 percent of online survey completions now happen on mobile devices. The proportion is higher for consumer surveys distributed via social media or SMS, where mobile-only respondents can represent the majority of the sample.

MindProbe uses a responsive layout that automatically adjusts question display to the respondent's screen size. Designers can preview the mobile view before launch to catch display issues.

• Screen size. Mobile screens are typically 4 to 6 inches wide. Long question text, wide matrices, and small radio buttons that work fine on desktop become difficult to read or interact with on mobile.
• Input method. Desktop surveys are navigated with keyboard and mouse. Mobile surveys rely on touch. Buttons need to be large enough to tap accurately, and text inputs open a keyboard that covers part of the screen.
• Context. Desktop surveys are often completed at a desk in a focused environment. Mobile surveys are often completed in transit, between tasks, or with competing distractions. Shorter, simpler surveys perform better in mobile contexts.
• Connection variability. Mobile respondents may be on slower or variable connections. Surveys with large images or complex interactive elements may load slowly or fail to render correctly.

1. Responsive layout. Questions, images, and buttons automatically reformat for the device width. A responsive layout is the foundation — without it, everything else is irrelevant.
2. Touch-optimised inputs. Radio buttons and checkboxes should be large enough to tap without pinching. Slider scales need clear boundaries and a visible thumb.
3. Short question text. Long question stems that fit one line on desktop may wrap to three or four lines on mobile. Shorter questions improve readability without reducing clarity.
4. No wide matrix questions. Grid questions with multiple columns display poorly on narrow screens. On mobile, either limit matrix width (three columns maximum) or convert matrix items to individual questions with a single rating scale.
5. Progress indicators. Showing respondents how far through the survey they are matters more on mobile because the lack of a scrollable overview means respondents cannot see how much remains.
6. Short survey. Mobile respondents are more likely to be in a context with distractions. Keeping the survey under five to seven minutes dramatically reduces drop-off.

Assuming mobile compatibility means mobile-optimised. A survey that technically loads on a phone is not the same as one designed for it. Check every question type in a mobile preview before launch.

Using wide image grids. Side-by-side image comparison questions work on desktop but force horizontal scrolling on mobile. Use stacked images or separate question frames instead.

Forcing landscape mode. Most mobile users hold their phone in portrait. Surveys that require landscape view add friction and cause errors.

Long open-text questions. On mobile, a large open-text field is awkward to use - the keyboard covers most of the screen and the respondent cannot see their full input. Limit open-text questions on mobile surveys or reserve them for the end.
