Because design is geared towards the individual user, navigation is often greatly improved. In a sense, dynamic design is more intuitive, as it takes into account user behavior. With a static site, all users are privy to the same exact layout.
A big part of SEO success is effectively targeting the right audience. A static website definitely falls short in this case, as it provides a uniform user experience to each person who visits your site. Dynamic design allows you to account for unique behaviors and activities for better audience targeting.
Your business may outgrow your website one day, which means it would need to be updated. Updating a dynamic site is often easier and less time consuming because of how these sites are built. Static sites that solely rely on HTML are usually more labor-intensive when it comes to making updates or changes.
