Performance and the ability to edit yourself might be the short answer. While WordPress may have started out years ago as a blog format CMS ( Content Management System) it has come a long way. The designing of your website will depend on the designer and their experience. However for the business owner (or an employee) to add new pictures, videos, edit existing pages, as well as create new pages, and “blog page” entries. It is very easy. If you can type or modify a Microsoft office document…you can edit your new WordPress website.
You also get a feature rich modern website with any features you need. Whether your needs just some basic things like slide shows or other photo galleries, contact, estimate, survey, review testimonials, or other forms on your website. Maybe your business needs a reservation or booking system? Are you a business that needs a full E-Commerce solution with real credit card processing and secure checkout? All these and more are available, while keeping a great user experience and fully responsive website, that works on all devices and browsers.
It also is easy to tie a WordPress website to your social media outlets for improved search engine performance. Even being able to post content across the web at once. Eliminated the need to post and repost on each website.
