How to Preview your site in Plesk
After you uploaded website files to the subscription, you can check how your site will look in a web browser, even before the information about the new site has spread in the Domain Name System.
To preview a site, perform the following steps:
1 – Logged in to Plesk.
2 – Go to Websites & Domains.
3 – Click Preview below the domain name of the website that you want to preview.
Your site will open in a new browser window.
