What are common website mistakes?

Common mistakes: slow load times, weak mobile layouts, unclear messaging, too many competing CTAs, thin content, and missing proof (reviews, work, stats). Technically, sites often fail on image/video weight, messy heading structure, broken internal links, and lack of analytics tracking. Design-wise, inconsistent spacing and typography make a site feel cheap. The fix is boring but effective: tighten the message, add proof, simplify the journey, and optimize performance. A clean site with strong fundamentals usually beats a flashy site with friction.
