Introduction
Conversion Rate Optimization (CRO) tools are software platforms that help businesses increase the percentage of website visitors who take desired actions—such as signing up, making a purchase, or filling out a form. These tools analyze user behavior, run experiments, and provide insights to improve website performance and conversions.
Instead of focusing only on driving traffic, CRO tools help businesses maximize the value of existing visitors, making marketing efforts more efficient and cost-effective. From heatmaps and session recordings to A/B testing and personalization, these tools provide actionable data to improve user experience and results.
