Problem: Marketing runs A/B tests on landing pages, but once leads hit Formstack, there’s no visibility into which experiment or variation actually produced the highest-quality submissions. Solution: Convert auto-populates hidden Formstack fields with experiment and variation data on every embedded form. Each submission is tagged at the source, so Formstack records show exactly which experience drove that lead. Outcome: Teams can compare lead volume and quality by variation directly in Formstack, prioritize winning experiences, and stop investing in tests that generate more leads but poorer pipeline or revenue impact.
