My website is getting a good amount of traffic, but visitors aren't turning into customers. People are visiting my pages, viewing products or services, and sometimes spending time on the website, but very few are making a purchase or contacting me.

What could be causing this problem? Is it because of poor website design, slow loading speed, weak product/service presentation, complicated navigation, lack of trust signals, pricing, poor mobile experience, weak calls-to-action, or an ineffective checkout process?

How can I identify exactly where visitors are dropping off and optimize my website to turn more of that existing traffic into leads, inquiries, and actual sales?
