AI-Only Pages vs Echo Knowledge Base – Documentation, FAQs, Chat & Smart Search

AI-Only Pages gives you granular control over which search engine bots can index each page on your WordPress site — while simultaneously making those pages more discoverable and useful for AI crawlers like ChatGPT, Claude, and Perplexity. The core idea: you have content that is perfect for AI training pipelines and retrieval-augmented generation (RAG) systems, but you do not want that content competing for rankings in Google, Bing, or Yahoo. AI-Only Pages lets you mark those pages as AI-only: they disappear from traditional search engine indexes while becoming first-class citizens in the AI ecosystem. What it does Per-bot noindex — Block individual bots (Googlebot, Bingbot, Yandexbot, etc.) with a checkbox per bot per page. Checking one bot blocks it; the others still index normally. “Block All” master toggle — One click blocks all 10 supported search engine bots simultaneously. tags and HTTP headers — Both HTML meta tags and X-Robots-Tag HTTP headers are emitted, covering all crawling contexts. Works correctly on all public post types including Pages and custom post types. SEO plugin integration — Suppresses Yoast SEO, WP Core, and RankMath’s global tag on AI-only pages so there is no conflict between the global tag and your per-bot tags. Sitemap exclusion — AI-Only pages are automatically removed from all XML sitemaps (Yoast SEO and WP Core sitemaps are both supported). /llms-index.txt — A plain-text AI discovery file served at yoursite.com/llms-index.txt listing all AI-only pages with their titles and last-modified dates. AI crawlers can use this file to find your AI-optimised content directly. Can be toggled on/off from the settings page. Token Diet — clean AI output — When an AI crawler visits an AI-only page, the plugin serves a cleaned version of the HTML with navigation, sidebars, footers, cookie banners, inline styles, SVGs, and iframes stripped out. AI models receive pure content with minimal noise. Global Settings Page — A top-level “AI-Only Pages” menu in the WordPress admin sidebar lets you configure Token Diet and LLM Index behaviour globally, without touching code. Caching plugin notice — If WP Rocket, LiteSpeed Cache, or another full-page caching plugin is detected, an admin notice explains how to configure it to work alongside this plugin. The Settings Page A full settings page is available under AI-Only Pages in the WordPress admin sidebar. It provides: Section 1 — Instructions & Status: A “How It Works” guide covering the meta box, Token Diet, and LLM Index. A live, clickable URL to your /llms-index.txt file with a green/red status indicator showing whether the index is active. Section 2 — LLM Index Settings: A toggle to enable or disable /llms-index.txt globally. When disabled, the endpoint returns a 404. Section 3 — Token Diet Master Control: A master toggle to enable or disable Token Diet entirely. When off, AI bots receive raw, full HTML — identical to what human visitors see. Section 4 — Granular Token Diet Stripping: Individual toggles for each category of content stripped: Strip structural layout (headers, footers, sidebars, navigation, cookie banners) Strip tags and embedded CSS Strip elements (major token bloaters) Strip elements (maps, embeds, social widgets) Strip elements (Warning: removes WooCommerce Add to Cart buttons) Strip tags (Note: application/ld+json schema is always preserved) Supported Search Engine Bots Googlebot (Web), Googlebot-Image, Googlebot-News, Googlebot-Video, AdsBot-Google, Bingbot, Slurp (Yahoo), DuckDuckBot, Baiduspider, YandexBot. AI Bots Welcomed GPTBot, ChatGPT-User, ClaudeBot, PerplexityBot, YouBot, Meta-ExternalAgent, Amazonbot, Bytespider, Diffbot, cohere-ai, anthropic-ai, AI2Bot, OAI-SearchBot, and more. These bots are detected automatically and served cleaned content when they visit an AI-only page. Developer-Friendly Every major behaviour is extensible via WordPress filters. See the Developer Reference section below. The Settings class hooks into filters at priority 5, leaving priorities 10 and above free for developer overrides — so your custom add_filter() calls always win. Using the Plugin Per-page control Open any post or page in the WordPress editor. Find the AI-Only Pages meta box in the right sidebar. Check individual bots to block them, or use Block from ALL search engine bots to check all at once. Click Publish or Update to save. The noindex tags take effect immediately. Visit yoursite.com/llms-index.txt to confirm your page appears in the AI content index. Note: The master toggle requires JavaScript. The individual checkboxes always work regardless of JS state. Global settings Go to AI-Only Pages in the WordPress admin sidebar. Review the “How It Works” section and confirm your /llms-index.txt URL is live. Use the LLM Index Settings card to enable or disable the discovery file. Use the Token Diet — Master Control card to enable or disable all output cleaning. Use the Token Diet — Granular Stripping card to select exactly which HTML elements are stripped from AI output. Click Save Settings.
