AI Content Signals

Συχνές Ερωτήσεις

What happens if I have a physical robots.txt file?

The plugin will detect your physical robots.txt file and append Content Signals to the end of it. Make sure the file is writable (permissions 644 recommended).

Can the plugin create a robots.txt file if I don’t have one?

Yes! You can enable the option “Create physical robots.txt file if it doesn’t exist” in the settings. This will create a basic robots.txt with standard WordPress rules plus your Content Signals.

What rules are included in the automatically created robots.txt?

The plugin creates a basic robots.txt with these rules:
* Disallow /wp-admin/ (except admin-ajax.php)
* Disallow /wp-includes/
* Disallow /wp-content/plugins/
* Disallow /wp-content/themes/
* Disallow /wp-content/cache/
* Disallow readme.html and license.txt
* Automatically includes your WordPress sitemap if available

What if I use an SEO plugin that manages robots.txt?

No problem! The plugin uses WordPress’s robots_txt filter, so it will add Content Signals to the virtual robots.txt generated by your SEO plugin without conflicts.

Will AI crawlers actually respect these signals?

Content Signals is a proposed standard and not all AI companies have committed to respecting it. It’s a way to express your preferences, but not a guarantee of enforcement. However, major AI companies like OpenAI, Anthropic, and Google have shown interest in respecting such signals.

Can I use this with Cloudflare?

Yes! If you use Cloudflare’s managed robots.txt, you can still use this plugin. The settings will apply to your WordPress-generated robots.txt.

What are the default settings?

By default, all signals are set to “yes” (allowed) for all user-agents. The option to create a physical robots.txt is disabled by default. You can change any of these settings in the settings page.

How do I remove Content Signals completely?

Simply uninstall the plugin. The uninstall process will remove all settings and clean up your physical robots.txt if applicable.

Can I transfer settings between sites?

Yes! Use the Export button on the settings page to download a JSON file with your full configuration, then use Import on another site to restore it. This includes global settings, individual bot overrides, and custom bots.

Is Content Signals an official web standard?

Not yet. Cloudflare published the Content Signals Policy in September 2025 and released it under CC0. The IETF has since created the AI Preferences (AIPREF) Working Group to develop a formal standard based on similar concepts. The plugin implements the current Cloudflare specification and will be updated as standards evolve.

Can developers extend the bot list programmatically?

Yes. Use the ayudawp_acs_predefined_bots filter to add or remove bots without modifying the plugin. Add this to your theme’s functions.php or a custom plugin:

add_filter( 'ayudawp_acs_predefined_bots', function( $bots ) {
    // Add a new bot.
    $bots['MyCustomBot'] = 'My Custom AI Bot';

    // Remove an existing bot.
    unset( $bots['Omgilibot'] );

    return $bots;
} );

The array key is the User-Agent string used in robots.txt and the value is the label displayed in the settings page.

Do I need to manually edit my robots.txt file?

No! The plugin handles everything automatically. Just configure your preferences in the settings page and save.
