Understanding survey fill speed

Understand typical survey timelines and what affects fill speed.

Updated today

Across surveys of different sizes and complexity, Attest surveys fill in around three days on average, with many completing within a day.

Actual fill time depends on how your survey is set up. Some surveys will complete much faster, while others may take longer depending on audience constraints and survey design.

With every survey, as soon as it is live you can see results in real-time in the results dashboard, you don't need to wait for the survey to fill to start looking at the results.


What affects how quickly a survey fills

Survey fill speed is primarily influenced by how easy it is to find eligible respondents.

Surveys tend to fill faster when they have:

Surveys typically take longer to fill when they have:

  • large sample sizes

  • narrow or niche targeting

  • multiple demographic quotas

  • qualifying questions that screen out many respondents

  • longer or more complex survey flows

If you need results within a short timeframe, reducing constraints where possible can significantly improve fill speed.


When responses slow down

It’s normal for response rates to slow as a survey progresses, especially once easier-to-reach respondents have already completed it.

A common reason for slower fill is a low incidence rate, meaning:

  • fewer respondents meet the combined targeting criteria

  • many respondents are screened out by qualifying questions

This is more likely when demographic filters, quotas, and qualifying questions are used together.


What to do if your survey is slow

If you notice that responses have slowed significantly or no new responses have come in for several hours, it may be worth reviewing your setup.

Possible actions include:

In some cases, changes can be made while the survey is live to improve fill speed.

If responses have stalled completely, or you are unsure which changes would have the biggest impact, get in touch with your Customer Research Manager or contact us via the in-platform chat. The team can review your setup and advise on next steps to help improve fill speed where possible.
