Safely manages website-use preference signals in a physical robots.txt file.

== Description ==

BlogLogistics Content Signals for Robots.txt safely manages the website-use preference line in a physical robots.txt file.

This plugin is intended for websites that already use a real robots.txt file on the server. It does not rewrite the whole file. It only manages the Content-Signal line placed directly under User-agent: *.

The default setting is:

• Search results: On
• AI answers: On
• AI training: Off

This creates:

Content-Signal: search=yes, ai-input=yes, ai-train=no

These settings publish your website’s preferences in robots.txt. They do not guarantee that every crawler, search engine, or AI system will follow them.

== Features ==

• Adds or updates the Content-Signal line directly under User-agent: *.
• Restores the original Content-Signal line when management is turned off.
• Removes the managed line when management is turned off and there was no original line.
• Performs surgical edits only and leaves all other robots.txt lines alone.
• Saves a backup before changing robots.txt.
• Keeps only the latest 5 backups to avoid filling the server with old files.
• Adds settings under BlogLogistics > Robots.txt Content Preferences.
• Shows the full robots.txt file for review and manual editing.
• Syncs the plain-language toggles when the Content-Signal line is manually edited.
• Shows when the file was last changed by this plugin.
• Lists available backups and allows restoring a selected backup.
• Removes plugin settings and plugin-created backup files when the plugin is deleted, while leaving the current robots.txt file as-is.
• Uses BlogLogistics manifest-based updates.

This plugin is provided by BlogLogistics as part of an active hosting, maintenance, or site-management service, unless a separate service arrangement has been granted. If the website is moved to another provider, continued BlogLogistics service use, support, updates, configuration assistance, or replacement work may require a separate agreement.

== Installation ==

4. Confirm the physical robots.txt file is found and writable.

== Frequently Asked Questions ==

= Does this plugin rewrite my whole robots.txt file? =

No. It only manages the Content-Signal line under User-agent: * and leaves the rest of the file alone.

= Does this plugin work without a physical robots.txt file? =

This plugin is intended for sites that already use a physical robots.txt file. If no physical robots.txt file is found, the settings page explains that the plugin cannot manage it automatically.

= What happens if I turn management off? =

If there was an original Content-Signal line, the plugin restores it. If there was no original Content-Signal line, the managed line is removed.

= Why does the plugin save backups? =

Before changing robots.txt, this plugin saves a backup copy. The plugin keeps the latest 5 backups so you can recover from mistakes without filling your server with old files.

= Can I manually edit robots.txt? =

Yes. The settings page includes a full robots.txt editor. If you manually change the Content-Signal line under User-agent: *, the toggle boxes update to match after saving.

= Can I restore a backup? =

Yes. The settings page lists the latest available backups with restore buttons. Restoring a backup replaces the current robots.txt file with the selected backup. No new backup is created during restore.

= What happens if I delete the plugin? =

The plugin removes its saved settings and plugin-created backup files. Your current robots.txt file is left as-is.

= Does this plugin continue to be covered by BlogLogistics service terms if the website moves to another provider? =

This plugin is licensed under GPL-3.0-or-later. BlogLogistics service use, support, updates, configuration assistance, or replacement work may require an active BlogLogistics hosting, maintenance, or site-management service, or a separate agreement. This notice does not restrict any rights granted under the GPL-3.0-or-later licence.
