Understand the Funnel

The Funnel tab on a survey's Insights page follows people from opening your survey to answering every question. Use it to find questions that people skip, linger on or leave at.

The Funnel follows the date range picker at the top of the Insights page.

The summary

At the top, a short note sums up how the survey is doing. Below it are four numbers:

• Opened. How many people opened the survey link. Older responses may show Not tracked, because opens are only recorded on newer ones.
• Submitted. How many people reached the end and sent a response.
• Completion rate. Submitted responses out of everyone who opened the survey, tagged Healthy (70% or more), Below par or Low.
• Most skipped. The question left blank most often, and how many people skipped it.

The chart under these numbers shows three stages: Opened, Submitted and Answered all, where Answered all means submitted with no question left blank. Each stage shows how many people dropped out before the next.

Where people left

When someone opens your survey and leaves before submitting, Surbee records the question they were on and how they left. Once there's data, the Where people left section shows:

• How many people left partway through.
• How they left, for example Closed the page, Switched tabs, Went idle, Stuck on a question, Left mid-answer, Left right away, Rushed, then quit or Submit failed. Hover over any of these for a description.
• A table of the Last question open before people left, how many left there, the most common way they left, and how long they spent on it.
• How far the people who left typically got, and how many were on a phone or tablet.

If nobody has left partway yet, you'll see a note saying exit tracking is on.

Questions to look at

Surbee flags questions that stand out from the rest of your survey:

• Often blank. Left blank by at least 3 people, and skipped at least twice as often as your typical question (and by at least 15% of respondents).
• Slow. Took at least twice as long as your typical question, and at least 15 seconds.

Flagged questions appear as cards under Questions to look at, each with a short explanation of why it was flagged and what that usually means.

Every question

The Every question table lists each question with:

• Answered. The share of submitted responses that answered it.
• Left blank. How many people submitted the survey without answering it. This usually means the question reads as unclear, optional or too personal.
• Time. The typical time spent on it.

Sort by any column, or switch to Flagged to see only the flagged questions.

Answer rate by device

If at least 8 people answered on a phone and at least 8 on a desktop, the Answer rate by device chart compares how often each question was answered on each. If phone users answer a question at least 10 points less often, Surbee points it out. Try that question on a phone yourself: the layout may be getting in the way.

What the Funnel can't tell you

A few other limits to keep in mind:

• Left blank counts skipped questions. The Answered and Left blank figures come from submitted responses only. A question with a high Left blank count is one people skipped and then carried on past. To see where people stopped, use Where people left.
• Opens are needed for the completion rate. For older responses where opens weren't recorded, the completion rate shows Not tracked.
• Small samples are noisy. With fewer than 20 submitted responses, the summary note reads Too few responses to read much into this. Treat the figures as a first look.
