What is conversion rate optimization?
TL;DR
Conversion rate optimization (CRO) is the practice of improving the percentage of visitors who take a desired action (buy, sign up, book). For most small businesses, the average website converts at 2-3%. CRO can double that without spending more on traffic.
Detailed answer
- 1.Conversion rate = conversions / total visitors × 100.
- 2.Average across industries: 2-3%. Top performers: 5-10%.
- 3.Highest-impact CRO levers: clear value proposition, social proof, fewer form fields, faster page speed.
- 4.Test one variable at a time using A/B tests.
- 5.Mobile conversion is usually 30-50% lower than desktop — fix that first.
Common mistakes
- 1. Testing too many variables at once with too little traffic.
- 2. Optimizing for clicks instead of revenue per visitor.
- 3. Ignoring the post-click experience (slow site, confusing checkout).
What to do instead
Start with qualitative research. Watch 10 users navigate your site (use a tool like Hotjar) before you change a single button color.
Focus the first round of CRO on social proof: customer photos, reviews, real testimonials. This single change typically lifts conversion 15-30% for small businesses.
