While optimizing, you must avoid these rookie mistakes that waste time and resources Ignoring mobile users: You’re losing conversions if your site isn’t mobile-friendly. Testing without enough data: Small sample sizes will lead to misleading conclusions. Overcomplicating the design: Too many elements overwhelm visitors. Using vague CTAs. Stuff like "Learn more" is weak; "Get your free trial" is stronger. Not considering page speed: Because slow sites kill conversions. Not having great UX: A confusing layout frustrates users. Making changes based on assumptions: Always test instead of guessing. Avoid these, and you’ll be on the right path to better results.
