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.
Sure, Squarspace isn’t that cheap. But there are NO hidden fees or complicated stuff. Trust me, I’ve tried everything, but they are all disappointing. Squarespace has not suspended me or those stupid rules other site builders have. You’ve got to pay more to do some advanced stuff like coding but there is always a workaround. It’s the best platform I have ever found!
Stop whatever you're doing and ask yourself this simple question: "Do I need a website?" If your response was anything other than "yes," you need to think again. It doesn't matter if you're the head of a multinational corporation who employs thousands of people or a local mom-and-pop shop from around the way, you need a website to help potential customers find you online. If you have a business, failure to establish an online home is a failure to grow.
All of the site builders included here let you put Facebook Like and Twitter Follow buttons on your pages, and some even let you display feeds from the social networks. Some give you help building a Facebook Page and tying it into your site design and updates. Many products offer some sort of SEO tool, but too often this is just a form on which you can enter meta tags. You're mostly left to wrestle with that black magic known as SEO for yourself. It's very important to submit and verify your site to the search engines, unless you don't want anyone to find it! Best FREE Website Builders!
