But, again, operationally it's quite strong. 24/7/365 customer support is available not only by live chat and email, but by phone. It offers free site migrations with some dedicated attention paid to making a transfer as smooth as possible. And, if you're willing to go for one of the higher-end plans, the company has put some serious attention into performance and caching.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.
Just because it's green doesn't mean it limits your power to do what you need with your websites. Rather surprisingly, its low-end account provides both SSH and WP-CLI (useful for WordPress websites and automated WordPress deployments) access, along with Git preinstalled. It's also possible to customize PHP and PHP.INI, a capability unheard of on a low-end plan.
Arguably one of the most flexible and easy-to-use builders, Site123 lets you customize anything and offers a one-click installation wizard with graphics and templates. Site123 stands out as particularly helpful with its free images library, professional fonts to add visual elements to your site, and creative DIY plans for creating multiple pages (which are unlimited). Plus, since it offers web hosting domain registration, 500 MB storage space, Google Analytics, and is ad-free, you won't feel pressured to switch to a paid plan.
When you sign up for SiteGround, you get a proactive chat from a live agent offering to call you, inquiring if you need any help setting everything up. Customer support includes tutorials, live chat, tickets, and phone calls. All are available 24/7 - and when you call on a Saturday night and get connected to an agent in 10 seconds, you know you're getting your money's worth.
