WordPress Plugin: SEO Optimization Solution for Generating llms.txt Files for AI Crawlers

This article introduces Kashiwazaki SEO LLMs.txt Generator, an SEO plugin designed specifically for WordPress. It dynamically generates llms.txt and llms-full.txt files, helping website administrators control AI crawlers' scraping and learning of content, and optimize content visibility and control in the AI era. This plugin addresses new challenges faced by traditional SEO with the rise of AI systems, providing flexible configuration and security guarantees.

With the development of LLM and AI technologies, AI systems like ChatGPT have become information acquisition channels, so traditional SEO needs to adapt to new changes. The llms.txt standard has emerged, similar to robots.txt but more precise:

• llms.txt (Summary Version)：Contains website name, content titles and URL lists (Markdown format);
• llms-full.txt (Detailed Version)：Contains article titles, publication/update time (UTC), abstracts and other metadata. The double-layer design allows AI crawlers to choose data depth as needed.

The core features of the plugin include:

1. Real-time Dynamic Generation: No physical files; generates the latest content from the database in real time when accessed, no manual updates required;
2. Content Type Selection: Can control whether posts, fixed pages, custom types, and media files are included;
3. Scraping Limits: Set a maximum limit of 1-10000 entries for each content type (default 1000 latest entries) to ensure reasonable file size.

The plugin provides fine-grained control:

• Content License: Configure via YAML whether to allow AI training/commercial use (example: allow-ai-training: true);
• Access Frequency Limit: Set the number of requests per second/minute, which can be enabled or disabled;
• Allowed Crawlers List: Supports a whitelist of 9 mainstream AI systems (such as ChatGPT, Claude, Perplexity, etc.).

System Requirements: WordPress 5.0+, PHP7.4+, memory recommended 64MB or more, supports multi-site; Security Features: Only administrators can configure, CSRF protection (Nonce verification), input sanitization and output escaping, compatible with mainstream cache plugins; Performance Optimization: Supports cache from 3 hours to permanent, one-click cache clearing, reduces database query pressure.

2. Upload to the /wp-content/plugins/ directory;
3. Activate the plugin in the backend; Configuration: Enter the plugin settings page, select content types, set maximum numbers, configure permissions and restriction rules; Verification: Visit https://yourdomain.com/llms.txt and llms-full.txt to check the generated results.
