Here are a couple of tools that can help you improve your conversion rates:
Google Analytics (free and paid versions) records the conversion rates for every page on your site, along with every user’s traffic source. Use it to identify poorly-converting pages that need your attention.
Hotjar (free and paid versions) shows you how people interact on your poorly-converting pages and what obstacles they are facing. You can also ask your users to share their feedback.
Pro tip: GA and Hotjar complement each other. Google Analytics tells you where your users are having problems, and Hotjar helps you find and fix the issues behind the problems.
