What are conversion rate optimization (CRO) tools?

CRO tools are software apps designed to help online businesses increase conversions with tactics including A/B testing, survey collection, marketing personalization, and analysis of visitor behavior. A combination of these tactics helps find problems, test solutions, and verify improvements in how effectively a website converts visitors into customers.

With CRO tools, you can tackle many projects, no matter how complex they are. Some common projects include ecommerce personalization (like targeting new or returning visitors with different offers), A/B testing marketing messages (headings, CTAs, images, etc.), and analyzing visitor behavior with heatmaps and recordings to reduce bounces.

Although the customization features really lacked in the free version (especially in terms of colors), they were still enough to create an onsite survey that looked quite okay-ish.

Another features that deserves a mention was the AI survey builder.

It got what I was aiming for and made a survey with awesome questions in seconds, even though I only gave it one line: "I want to know why my visitors are leaving without buying:
