Summary  
This chapter describes how to integrate experimentation and analytics tools into your code to run controlled A/B tests, collect user interaction data (heatmaps, session recordings, surveys), and apply continuous optimizations based on statistical analysis.  

General domain of usage  
Landing page optimization

Even well-designed landing pages can improve over time. Testing and behavioral analysis tools help you identify what's working, what's not, and how to optimize your approach systematically.


### Key Points:
- Don't guess - **test and observe**. Continuous optimization can steadily improve ROI and lower cost per acquisition;
- **Google Optimize** (or similar tools) lets you run A/B tests, comparing page variants to see which performs better. Common test elements include headlines, CTA buttons, layouts, or pricing displays;
- **Hotjar** reveals actual user behavior:
   - **Heatmaps** show where people click, scroll, or ignore;
   - **Session recordings** let you watch real visitor journeys;
   - **On-page surveys** help uncover why users didn't convert.
- Continuous improvements compound over time; even small tweaks, such as a better headline or faster load time, can **significantly boost conversions**.
