The launch of Google Sites in 2008 brought users simple site creation. Eight decades after, a fresh Google Sites was introduced to the masses to replace the withering shell of classic Sites and become a part of G Suite — allowing for simple integration with Documents, Sheets, and Slides. In an email sent out to customers, Google notified that the service would be sent off in 2021.
It allows you to convert, archive, or delete any Websites on your accounts, as well as export a spreadsheet of your websites to Google Sheets.
In addition, G Suite admins are provided a different timeline to transition, according to the G Suite Updates Blog.
To start this transition Sites development will be disabled on November 1, 2020, and point users will have a little, under a year to move to the brand new Google Sites.
