What's the best practice for implementing third-party CRO scripts?

As an e-commerce manager, I'm looking to optimize my conversion rates by integrating third-party conversion rate optimization (CRO) scripts. However, I'm concerned about potential performance impacts, data privacy, and ensuring these scripts don't negatively affect my website's user experience or loading speed. I need a comprehensive strategy for evaluating, selecting, and implementing CRO scripts that will genuinely improve my store's performance without introducing unnecessary risks or technical complications.
