Your site's domain is like its street address, it lets other people find it (like bokun.io). The Bókun website builder automatically generates a domain using your details on Bókun. For example: www.sarahswalkingtour.bokun.website.io.
However, we strongly recommend that you buy your own unique domain, specific to your business’ name or unique selling points. A good domain can increase the traffic to your page and make it easier for your customers to find.
If you'd like your own custom domain for your Bókun website, you can buy one from any domain provider you prefer. To make this process easier for you, we’ve put together some guides for popular providers below:
