Hidden fields in survey forms are a powerful tool that allows you to identify users without having to ask them directly. This is accomplished by incorporating any data that you have previously collected on the users into the survey. This streamlines the process for the user, and also allows you to personalize the survey to their specific needs, thereby increasing the likelihood of generating valuable, actionable insights.

In this order of ideas, hidden fields are useful and can save time. You may already have a lot of user information like names, emails, and job details. Therefore, there's no need to ask for this information again in your survey. Instead, these fields can help link existing data to user responses.

Understanding Hidden Fields

As mentioned before, hidden fields are a feature that allows you to use data you already have. Still, also you can track information about your respondents, and make your surveys more personal.

What to use hidden fields?

  • Track the source of respondents (social media channels, for example)

  • Segment your audience for deeper insights and analysis

  • Customize your survey to make it even more personal

What information is collected with hidden fields?

  • Name

  • Email

  • Job position

  • Traffic source

  • Date

  • Age

  • and many more

Add hidden fields using no-code

Add your data directly to the URL shown to your users or mobile app. Users won’t need to bother with anything other than answering your most important questions. Below we will show you how to do it from Told.

For the widget in-app or website

  1. Install the Told SDK on your website/application.

  2. Set up the hidden fields in the code using our SDK.

    Here’s an example of the code:

    const user = { name: 'Jon', email: '' } told('addHiddenFields', user);

  3. From now on, when a user responds to one of your surveys, you’ll see user’s hidden fields in the report. Just like this

In a survey shared by link

  1. Add the data directly to the URL.

    In this example, I will add to hidden fields, the name and email of my user:${surveyID}/voting?name=toto&

  2. From now on, when a user responds to one of your surveys, you’ll see the user’s hidden fields in the report.

What will data collection look like?

In your Responses tab, you can see each answer submission and its hidden field data. If you already have data associated with your product, you can track it and add it to your table view thanks to your hidden fields.

In the report table, you can see your answers from the hidden fields. Just like this:

Filter your hidden fields

Send your survey with hidden fields like name, job position, and department. This will allow you to better categorize and understand the responses with context. After you have collected all the answers, you can then proceed to use the filters feature. This will allow you to sort the data and isolate answers based on various criteria.

For instance, if you are particularly interested in feedback from the marketers or designers, you can adjust your filters to only display answers from these specific roles. If you want to further analyze the data or need to present it to other stakeholders, you can create custom reports. This allows you to save filtered data for future reference and makes it easier to share insights with others.
