Conditional Logic Form Builder: Use Cases, Benefits & Templates

Conditional logic changes how your online form behaves based on specific user actions. It allows you to dynamically customize the form experience based on your respondents’ answers.

The best thing? It doesn’t require coding skills or technical knowledge. To set up question logic all you’ve got to do is define AND/OR conditions with our visual editor while working on your logic form or landing page.

Conditional logic forms sends users on different journeys based on their choice selections. LeaGen App also provides conditional form endings, sending users to different thank you screens.


Benefits of Conditional Logic Forms

With conditional logic forms, you can hide or show questions based on a previously selected answer. You can also skip to a different page, allowing you to make complex forms with minimal effort.


  • Streamline your online forms
    Conditional Logic can make an online form more digestible and less confusing for users by hiding irrelevant fields.


  • Keeps forms shorter
    Considering humans have a shorter attention span than goldfish these days, it’s a good idea to make your forms appear as short as possible at the outset (which can be accomplished by hiding fields until they are needed).


  • Personalized form experience
    You can use Conditional Logic to display custom messages based on a user’s interaction with your form, which can make the experience more personal and engaging.


  • Reduce the number of choices per question
    Leave out unnecessary form content that doesn’t apply to certain form visitors. Conditional logic makes it possible to present on the right content to visitors.


  • Increase conversions:
    If the relevance of your content is improved, you are also maximising the chances of users completing the form. Your visitors will be less overwhelmed helping you collect more responses and capture more leads.

Best Practices For Using Conditional Logic Forms 

Before you start adding conditional logic to your form fields, let’s go over some best practices. These will help you improve your form conversions and ultimately your bottom line.

Keep Your Forms Simple

Just because you can hide fields behind conditional logic doesn’t mean you should add unnecessary elements to your forms.

Generally speaking, shorter forms create a better user experience and increase the likelihood a user will complete it. In an Unbounce case study (source under graphic), an 11-field form saw a 120% increase in completions when it was reduced to four fields.

It’s still important to keep your conditional logic forms as simple as possible so you don’t overwhelm your users. You don’t want your users to stare at your forms and think, “Why do they need this?”. That means…

  • Don’t ask for any information you don’t need.
  • Don’t ask for information you don’t need right away.
  • Don’t ask for anything you could easily learn on your own.
  • Avoid asking for anything your users don’t know off the top of their head.

Test Form for Best Conversions

That said, there are some exceptions. Removing fields doesn’t always increase conversions. It’s always important to A/B test your forms to discover what works best for your audience.

Match The Content with Trigger Condition

This should go without saying, but we’ve seen it before so it’s worth mentioning.
The question that opens after a conditional trigger should clearly relate to the messaging of the step before.

For instance, if user selects a choice that indicates he’s interested in “Landing page design services”, the next step needs to match this content and deliver on this service need. Changing the topic or starting with another generic question generates confusion.

Another example: A conditional form asking for your country, should follow-up on this question with the next relevant questions, e.g. “What city are you in?”, or other questions, but no longer revert back to questions that would no longer make sense to ask based on this country.

Conditional Logic Form Example

This is a recruitment newsletter form to provide relevant content for job applicants presenting location-based job openings based on location selection. The goal of the form is to filter enquiries and narrow down targeting to a very close range. Conditional logic helps to ask relevant questions following up on the candidate’s prior response.

LeadGen App provides various conditional form templates that you can easily customize to your needs.
