CRO Concepts & Glossary
Plain-language definitions of conversion, CRO, AEO, micro-conversions, funnels, bounce vs. exit rate, and the rest of the growth vocabulary.
- What Is Above the Fold in Web Design? — Above the fold is everything a visitor sees before scrolling. It carries most of your conversion weight because many people never scroll. Here's what belongs there and why.
- What Is Bounce Rate vs Exit Rate? — Bounce rate is the share of single-page visits; exit rate is the share of visits to a page that ended there. They sound alike but answer different questions. Here's a worked example.
- What Is a Call to Action (CTA)? — A call to action (CTA) is the element that prompts a visitor to take the next step — usually a button or link like 'Start free trial'. Here's what makes one work, with examples.
- What Is a Conversion Funnel? — A conversion funnel is the ordered set of steps a visitor takes toward a goal, with people dropping off at each one. Here's a clear definition, a worked example, and how to read it.
- What Is a Landing Page? — A landing page is a standalone page built around a single goal — usually one conversion like a signup. It differs from a homepage by having one focused action. Here's how, with a structure.
- What Is a Micro-Conversion? Examples for SaaS — A micro-conversion is a small, measurable step a visitor takes toward your main goal — like starting a signup form or viewing pricing. Here's a clear definition, SaaS examples, and how to track one in PostHog.
- What Is Conversion Rate Optimization (CRO)? — Conversion rate optimization (CRO) is the practice of systematically increasing the share of visitors who take a desired action. Here's a plain-language definition, a worked example, and a repeatable CRO loop.
