Why Most Website Design Mistakes Cost Leads in 2026
User journeys are more impatient now. Most traffic is mobile, and attention is shorter. Mobile users’ behavior rewards clarity and speed.
People also trust fewer businesses online. They look for signals of website credibility. They want proof before they click.
If your site feels confusing, visitors bounce. That bounce rate often signals poor user experience. It can also reduce SEO performance over time.
