Your free Yola URL is in the format: websitename.yolasite.co
Note: You cannot edit the free URL. The URL is assigned automatically when you publish your site for the first time. Most times, it is based on your website title you have entered during the site setup process.
You can make changes to your website name following this tutorial.
When you purchase a Yola plan, you are welcome to continue using the free Yola URL if you do not want to connect your own custom domain.
Note: Even if you decide to purchase and connect a custom domain, your site is still accessible through your free Yola URL.
