Conditional logic makes a form, survey, or funnel react to what a person has already answered. Instead of showing everyone every question, rules decide what comes next: show a field only when it is relevant, skip a block that does not apply, or branch a respondent down a different path entirely.
The common patterns are skip logic (jump past irrelevant sections - someone who did not contact support never sees support-quality questions), branching (route detractors and promoters, or personas, down different paths that can reconverge), and piping (carry an earlier answer into a later question's wording). Done well, every respondent feels the survey was written for them, which both protects data quality and lifts completion.
In lead funnels, conditional logic also drives scoring and outcome routing - thresholds on a lead score can decide whether a visitor sees a booking calendar or an email-nurture ending. The surveys guide and funnels guide cover the patterns, and conditional logic without writing code shows how to set them up.
