Customizing Site Files
Requires Pro Plus or higher
More advanced use cases may require you to customize one or more of a site's supporting files (such as its robots.txt or ads.txt files), in which case the Site Files feature will allow you to do just that. Here's how:
Open the Dashboard.
Click the Sites tab.
Locate the site in question, then click its Manage icon.
In the sidebar, click Files.
Locate the file you wish to edit, then click its Edit icon.
Make your changes to the file's contents (or simply clear its contents to omit this file).
Click Update File
You're done! You can now preview the file's contents by clicking its Preview icon.
