New for Umbraco 8, Robots.txt Editor v8!
Adds a dashboard editor to the settings section, which allows access to your Robots.txt file from the root of your website. If you do not have an existing Robots.txt, then one will be created for you.
The editor contains basic validation for the Robots.txt protocol.
Version 8+ works with Umbraco v8.2+.
Previous versions were developed for Umbraco v4 (and worked on v6 and v7) are available in the Archived Files section.
