Conversion rate optimization (CRO) is the practice of increasing the percentage of website visitors who take desired actions — whether that's making a purchase, signing up for a newsletter, or downloading a resource. In 2026, with attention spans shorter than ever and competition fiercer than ever, every percentage point increase in conversion rate can translate into significant revenue growth. This comprehensive checklist covers everything you need to optimize your site for conversions.
