Best Conversion Rate Optimization Metrics to Track and Optimize
Track conversion rate, bounce rate, and Core Web Vitals in GA4, then use WP Rocket to improve page speed and test changes with Hotjar and Optimizely.
Configure GA4 conversion events for key actions, enable WP Rocket caching and minification, then run Hotjar heatmaps to identify friction, and perform A/B tests with Optimizely to validate improvements.
Summary
WP Rocket’s guide explains how to boost conversions by tracking the right metrics. It lists seven core CRO metrics, including conversion rate, bounce rate, shopping cart abandonment rate, and Core Web Vitals, and shows how each reveals friction in the user journey. The article demonstrates how to set up conversion events in Google Analytics 4, navigate to Reports > Engagement > Conversions, and calculate conversion rate with the simple formula. It also highlights that page speed and Core Web Vitals directly influence conversion, recommending WP Rocket’s caching, minification, and image optimization to reduce load times. Hotjar heatmaps and recordings are suggested for visualizing user behavior, while Optimizely is recommended for running A/B tests to validate changes.
An example case shows a WooCommerce store losing sales at the final payment step due to unexpected shipping fees; correcting the fee dropped cart abandonment and improved conversions. The guide stresses that every metric should be actionable and tied to business goals, and it encourages using WP Rocket to improve performance, GA4 for tracking, and Hotjar/Optimizely for experimentation. By combining these tools, agencies can turn data into concrete UX improvements and measurable revenue gains.
