How to Change Weebly website address
You can change the name of your weebly site any time you want. It is normal for people to start with one sub-domain name and then later realize a name that fits better. When we put the http://usingblogs.weebly.com, we initially picked a different name and put the site together. Once it is done, we figured that the original name does not reflect what we really wanted to do with the site. Our aim was to show how people can use weebly blogs to create a real estate agency website. So, we changed it to http://UsingBlogs.weebly.com. This new name not only describes the purpose of site, but is also a good choice for SEO (search engine optimization). To change the name, go to Settings –> General Settings.
The first item in General settings is “Address” and the option to “Change Site Address”. Click the “Change Site Address” link. You will now get the option to choose a different name, or to register a custom domain or use an existing domain name of yours.
You can change this any number of times you want. If you are choosing a weebly subdomain or registering a new domain, once you enter your choice, you will see if the name is available for you to pick.
