You can absolutely do that. If you want to upgrade to a paid plan to get some of the features you want, then you can switch at any time through the My Products option in your account or with the help of a GoDaddy Guide. Once you upgrade your site will have all the same customizations and work that you've already put in place, just with the added features. See Website Builder plans and pricing for more info.
How to create a Website in Google Sites for Free
I should highlight here that, much like all website builders, SITE123 is not without cons. It’s a simple and intuitive website builder, but it is more suited to building basic websites. If you use only the free options, you won’t be able to create anything but a simple personal website with SITE123. Meanwhile, its free plan has no duration constraints, but limits storage space to 500MB and bandwidth to 1GB.
You also want a web host with 24/7 customer support—if not by phone, then at least by chat. Forums, knowledge bases, and help tickets are all well and good, but sometimes you just need to communicate with another human to get things ironed out as quickly as possible. That said, not all 24/7 customer support teams are equal. Companies like GoDaddy and Liquid Web boast incredibly knowledgeable and helpful customer support squads—a fact that we confirmed in our in-depth reviews of those web hosting services.
While 000webhost is the best host on this list, you don’t want to skimp on your hosting by choosing a free or cheap plan. If you’re serious about your website, hosting is one of the essential choices you’ll make. It affects everything like site speed, uptime, security, and features. Don’t go cheap – make a small investment and secure your website’s future success.
