It doesn't matter if your website has been published already, or it's just a draft, you can easily preview it.

In your dashboard, hover the mouse over the ellipsis button ⋯ to see more options. If your website isn't published yet, you'll see the Website preview option. If your website is published, click on the View live website:

Alternatively, you can preview your website – published or not – within the editor. Simply click on the Preview button in the top right:

NOTE: Links (and other dynamic elements, e.g., some integrations) are often blocked in the editor and preview because some of them might not even exist until you publish or update your website. Once you do that, feel free to test everything online once more! 💡
