If you’re looking for a DYI friendly small-business website platform, the usual suspects are likely to include WordPress, Squarespace, Shopify, GoDaddy, Weebly, and hopefully Wix.
One of the main reasons these platforms are attractive is their ease in setup and updating. Even if you hire a designer to create your site, a user will find updating it as easy as using Microsoft Word or Google Docs. The similarity with document/content creation and using these tools is no coincidence. Indeed, they are called CMS platforms for this very reason (CMS = Content Management System).
