VWO Surveys FAQs – VWO

Does VWO capture partial survey responses?
Yes, VWO captures every user's response to each question, irrespective of whether the user clicks the Submit button at the end of the survey. It records the response when a user answers a question and clicks Next.

Note: VWO considers a survey attempted as soon as a visitor interacts with it, for example, by typing in a field, selecting an option, or clicking a button. This action immediately increases the attempted count by one. However, the actual response is captured only when the visitor clicks Next or Submit. If they abandon the survey without clicking Next or Submit, the response itself is not recorded, though the attempt is counted.
What happens if a user opens a survey but doesn’t type anything?
If a user does not enter any data, no response is recorded. Partial responses are only saved when at least one field is filled in.
If a visitor closes the survey, does it appear again?
If a visitor closes the survey using the X icon, the survey does not immediately reappear during the same session. Whether it appears again in a future session depends on your survey’s recurrence settings:
- If the survey is configured to show only once per visitor, it will not appear again.
- If it is configured to show again after a defined interval or number of visits, it may reappear based on those rules.
- If a visitor only minimizes the survey (and does not explicitly close it), it may reappear upon page refresh or navigation, depending on your trigger settings.
  The maximum number of times a survey can reappear is governed by the display frequency settings configured during survey setup. For more information, see Configure Survey Delivery Options.
How can I reorder the sequence of questions?
To reorder the sequence of questions, go to the Question Configuration page. On the right panel, drag the question block and drop it where you want in the sequence of questions.
How many questions can I add to a survey?
VWO Pulse puts no restrictions on the number of questions you can add to a survey. However, having more questions in a survey adversely affects response and completion rates. Therefore, it is recommended to have at most 5 questions in a survey to get good response and completion rates.
Is there a limit on the number of responses?
Yes, response collection limits apply based on your plan.

VWO sets a generous response cap that is calculated using a multiple of your Monthly Tracked Users (MTUs) and plan duration. This limit is designed to ensure you can gather a sufficient volume of responses to generate reliable insights, while aligning with your subscription plan.

You can check your Sampled MTU quota in Settings > Subscription & Invoices > VWO Insights - Web section.
Can I customize the appearance of the survey window?
Yes, to customize the appearance of your survey, go to the Design tab in the survey builder, and select New Theme in the themes dropdown. This will load the CSS of the default theme. If you want to customize a different theme, click the theme dropdown and select it. Its CSS will be loaded, ready for editing. For more information, see Customize the Survey Appearance (Web or Mobile App/Link).

Note: Custom styling is available only from the Pro plan onwards.
Will using VWO Pulse surveys affect my website’s performance?
No, VWO Pulse surveys are served through the existing VWO tracking code. There is no additional tracking code required to serve surveys. The payload size doesn’t increase unless there is a survey running on a specific page.
Do VWO Pulse surveys support languages other than English?
VWO Pulse surveys have translation support. You can create, edit, and run surveys in any language you want. Even the reports support translation. The content that a visitor enters will be in the language they use. Only the text in the built-in form elements is defined in English and not currently customizable. For more information, see Add Translations.
Can I test a survey locally on localhost?
Yes, you can if SmartCode is installed on the page and the pattern matches the URL. Please be informed that VWO does not support running tests on localhost. It should be a valid domain name. Hence, for this, you will need to go into your /etc/hosts file and change the following line as: “127.0.0.1 localhost” to: “127.0.0.1 localhost localhost.com”.
Can I have a different theme for my survey?
Yes, VWO comes with 10 predefined themes you can use to create beautiful, contemporary surveys. For more information, see Customize the Survey Appearance (Web or Mobile App/Link).
Do VWO Pulse surveys work on secure HTTPS webpages?
Yes, if the domain you define is a secure HTTPS webpage, VWO Pulse surveys will work there. Not just this, VWO Pulse surveys will also work on HTTP webpages.
How does quota consumption work for surveys?
The survey quota is based on the number of survey responses you purchase, and the count is considered for all submissions (partial and complete). This means VWO counts a response as soon as a visitor starts taking a survey and answers at least one question, even if they don’t complete or submit the entire form.
Note: Survey quota consumption does not depend on your account's visitor sampling. For every successful survey submission, one visitor count is shown on the report.
See the following table for detailed insights on survey tracking.

Survey State	Visitor Action	Impact
Survey Completion	Completes the entire survey and submits it.	Displayed Survey: 1 Attempted Survey: 1 Completed Survey: 1 Quota Consumed: 1
Partial Attempt (Answered Some Questions, Did Not Complete)	Starts answering a few questions, but does not complete the survey.	Displayed Survey: 1 Attempted Survey: 1 Completed Survey: 0 Quota Consumed: 1
Partial Attempt (Attempts First Question, but Does Not Submit)	Attempts the first question but abandons the survey without submission.	Displayed Survey: 1 Attempted Survey: 1 Completed Survey: 0 Quota Consumed: 0
No Attempt (Survey Shown but No Question Answered, User Closes or Ignores the Survey)	Closes or skips the survey. The survey is displayed, but the visitor does not answer any questions.	Displayed Survey: 1 Attempted Survey: 0 Completed Survey: 0 Quota Consumed: 0
Page Closed After Survey Displayed	Closes the page immediately after seeing the survey.	Displayed Survey: 1 Attempted Survey: 0 Completed Survey: 0 Quota Consumed: 0
Page Closed Before Survey Displayed	Closes the page before the survey is displayed.	Displayed Survey: 0 Attempted Survey: 0 Completed Survey: 0 Quota Consumed: 0

You can check the survey quota consumption in the Settings > Subscription & Invoices > VWO Insights - Web section.

Can I trigger a survey once a visitor scrolls down a page?
Yes, VWO Pulse surveys allow users to trigger a survey if a visitor scrolls a certain amount on a page. A user can define the number of pixels or percentage of page height a visitor needs to scroll either from the top or bottom of the page to trigger a survey. The percentage of page height is useful for webpages with a fixed height. However, for infinitely scrolling pages such as search results on an e-commerce webpage, actual pixels scrolled is more reliable. For more information, see Define the Survey Trigger (Web or Mobile App/Link).
What does the survey preview show?
The survey preview shows any changes you make to the question immediately. The preview is how the real survey will look and is completely interactive. So if you are editing the welcome screen, the survey preview will display the Welcome screen.
Can I trigger a survey when a visitor converts for an existing goal in VWO?
Yes, using a custom trigger, you can display a survey to a visitor if they convert for an existing goal in VWO. You can use the following code in the custom trigger to display a survey if a goal is converted for an existing campaign in VWO.
Note: Replace CAMPAIGN_ID and GOAL_ID with your campaign ID and goal ID, respectively. Goal IDs are available in the report against each goal name. So goal G1 has a goal ID of 1, goal G2 has ID as 2, and so on. Variations IDs are available in the report against the variation names. So variation v1 has a variation id of v2 (control has the variation ID of 1), and so on.
```
function() {
window.VWO = window.VWO || [];
VWO.push(['onGoalTrigger', CAMPAIGN_ID, GOAL_ID, function() {
executeTrigger();
}])
}
```
