WordPress and WIX are two software platforms used to build websites. It’s like using Microsoft Word or Google Docs to make a document.
I offer both because each has its pros and cons, and website owners come with a wide range of experience and expectations.
In a nutshell:
WordPress is best for low monthly costs, more sophisticated features, and if you would prefer me to manage updates to the site.
WIX is best if you have regular updates to the site content that you’d like to manage yourself.
Note that visitors to your website won’t be able to tell which software was used to create the website. Either will look amazing.
