Form optimization is the process of refining a form's fields, layout, and copy to reduce friction and increase the percentage of visitors who complete it. Common tactics include cutting unnecessary fields, clarifying error messages, and testing single-column versus multi-column layouts, all core levers in conversion rate optimization (CRO).
Example
Asking for email first and company size later, plus inline error messages, turns a long form that people abandon into one they finish.

Conversion Rate Optimization
CRO is the process of improving a website to turn more visitors into leads, customers, or sales.
CRO (conversion rate optimization) is the process of improving your website so more of your existing visitors take action — buy, book a call, submit a form — without spending more on traffic. Most businesses focus entirely on getting more visitors and ignore what happens once people arrive. CRO fixes that gap. A 1-2% conversion rate improvement often outperforms a traffic increase, because it compounds on every visitor you're already paying to attract.
Start with your above-the-fold messaging, simplify your calls-to-action, and remove friction from forms — these three changes account for most conversion gains before anything else matters. After that, test one variable at a time: headline, CTA placement, form length. Use analytics and session recordings to see where visitors actually drop off instead of guessing. CRO is iterative — small, evidence-based changes compound over months.
