Tool Bloat vs. Insight Clarity – Building the 2026 Stack
I have Hotjar for heatmaps, Optimizely for testing, GA4 for data, and three different survey tools. My site speed is tanking, and none of the data matches up. How do I simplify without losing the ability to test?

You’re running into a classic CRO stack overload problem. Too many tools create conflicting data and hurt performance. I’d simplify by keeping one core analytics tool (GA4), one testing platform (Optimizely), and one behavior tool (Hotjar). Drop overlapping survey tools and consolidate insights in one place. Also, make sure scripts load asynchronously or via a tag manager to protect site speed. The goal isn’t more data—it’s clearer decisions. This guide helped me rethink my stack: https://conversionrate.store/blog/best-cro-software-tools Start lean, then add tools only if they provide unique value you actually use.
