One-V LLM Serve vs Website LLMs.txt

One-V LLM Serve makes every public page on your WordPress site available as clean Markdown at the same URL with a .md extension — zero configuration required. https://example.com/about/ ← HTML page for humans https://example.com/about.md ← clean Markdown for AI AI systems — ChatGPT, Perplexity, ClaudeBot, Google AI Overviews, and most RAG pipelines — parse Markdown far more efficiently than HTML. When these systems encounter an HTML page, they must strip navigation, headers, footers, sidebars, scripts, and tracking pixels before they can read the actual content. This noise introduces errors, increases token cost, and leads to lower-quality outputs. The Markdown file contains a configurable YAML frontmatter block followed by the page title, headings in correct hierarchy, and the body text. Nothing else. Core features Zero-config Markdown endpoint for every public post, page, and custom post type YAML frontmatter with configurable fields (title, date, modified, url, description, image, tags, categories, lang, type) /llms.txt discovery file at the site root following the llmstxt.org convention Taxonomy archives as Markdown — /category/news.md, /tag/foo.md, custom taxonomies ?format=markdown query parameter as an alternative to the .md URL on any singular page Per-post exclude via a sidebar checkbox on the post editor Works with Classic Editor and Gutenberg via the the_content filter ACF integration — opt-in per-post: pick which text, textarea, WYSIWYG, URL, email, or link fields to append below the body Filterable AI analytics — per-hit events with full denormalised dimensions (UA bucket, referrer host, language, post type, response code), sticky filter bar that drives every chart and table live, six KPI tiles, a stacked-area time chart, three composition donuts (UA bucket / referrer source / language), four Top tables, a User-Agent classifier transparency table, and a Recent Activity stream. Referrers are tracked by hostname only — paths and query strings are stripped before storage so no PII is retained. Forward-compatible classification: when the bot or referrer catalogue is updated in a future release, historical rows are reclassified automatically — no Reset Analytics required. Browser-bucket sub-classification — anything that looks like a browser visit gets split into four kinds based on the Sec-Fetch-Site, Sec-Fetch-User, and Sec-CH-UA request headers a real browser sends: verified user (top-level navigation triggered by a click or address-bar Enter in a recognised browser), headed agent (real Chromium driven programmatically — Playwright, Puppeteer, Selenium), script agent (bare HTTP client imitating a browser UA — requests, httpx, LangChain, custom agents), spoofer (UA shape that no real browser would emit, like modern Chrome with a non-reduced UA). Visible as a stacked-bar breakdown on the User-Agents subpage so you can see at a glance how much of your “human” traffic is actually automation, and rendered inline as colour-coded slugs on every browser-bucket row in the Recent Activity table on the Analytics page. Detection is server-side fingerprinting of the request itself — no cookies, no JS, no IP. Discoverability Link: rel="alternate"; type="text/markdown" HTTP header on every HTML page tag in for HTML-based discovery Allow: /*.md$ directive in robots.txt CORS Access-Control-Allow-Origin: * on .md and /llms.txt so browser-based AI clients can fetch them Operations Transient caching with automatic invalidation on save_post, on ACF field value saves, on any ACF field group change, and on plugin settings save “Clear cache” button in the settings page Admin notice on fallback HTTP fetch failures “Settings” link next to the plugin row in Plugins screen “View .md” row action in the Posts and Pages list tables Developer hooks ovls_markdown filter for the final Markdown output ovls_frontmatter filter for adding, removing, or modifying frontmatter fields ovls_content_queries filter for the HTML extraction XPath cascade How it works Each request to /about.md is captured by a WordPress rewrite rule and routed through the plugin’s content generator. The generator runs the post through apply_filters( 'the_content', ... ) — the same pipeline WordPress uses on the front end — so Classic Editor, Gutenberg, and shortcodes all work without separate code paths. The rendered HTML is converted to Markdown via league/html-to-markdown, then cached in a WordPress transient. The cache is invalidated automatically on save_post, on ACF field/group changes, and whenever plugin settings are saved. A manual Clear cache button is also available on the settings page. Access methods There are three equivalent ways to request the Markdown version of a page: .md extension — https://example.com/about.md ?format=markdown query — https://example.com/about/?format=markdown Link: rel="alternate" header — returned by every HTML page The .md URL is the recommended canonical form. ACF integration When Advanced Custom Fields is active, ACF field rendering is opt-in at two levels: Site defaults per post type — at Settings → One-V LLM Serve → ACF Defaults, tick fields that should be appended to every post of a given post type. Per-post override — the One-V LLM Serve metabox on each post editor lists every supported ACF field applicable to that post. Tick fields to replace the site defaults for that one post. Supported ACF types: text, textarea, wysiwyg, url, email, link. Each selected field is rendered under a ## Field Label heading. Empty fields are skipped.

Website LLMs.txt generates and manages an llms.txt file, a structured, AI-ready index that helps large language models like ChatGPT, Claude, and Perplexity understand your site’s most important content. How llms.txt works Traditional sitemaps and robots files guide search engines. But as AI-driven systems such as ChatGPT, Claude, and Perplexity increasingly ingest web content, they benefit from a clear, structured list of a site’s most important URLs. llms.txt offers that: a plain-text or Markdown list of essential public URLs, optionally annotated with titles, descriptions, and grouping, designed for AI consumption rather than general web crawling. Key benefits ✅ AI discovery readiness: future-proof your site for AI indexing and content retrieval. ✅ Fully automatic: the plugin builds and updates your llms.txt file on its own schedule. ✅ SEO plugin integration: works seamlessly with Yoast SEO, Rank Math, SEOPress, and AIOSEO, automatically excluding content marked as noindex or nofollow. ✅ Advanced controls: choose post types, customize file titles or descriptions, attach optional Markdown files, and trigger manual regeneration. ✅ Developer-friendly: includes filters such as llms_generator_get_post_meta_description for description logic, performance tuning, and custom indexing behavior. ✅ WooCommerce & multisite ready: respects product visibility rules and scales easily across large or networked sites. Activation & setup Activate the plugin. Visit Settings → LLMs.txt to configure post types and update frequency (immediate, daily, or weekly). The plugin generates llms.txt (and optionally llms-full.txt) and serves it from your site root. Content updates trigger automatic regeneration. All noindex/nofollow rules from your SEO plugin are respected. Use cases for llms.txt Publishers, SaaS companies, developers, and documentation sites that want to make their content easier for AI systems to interpret. SEO-driven websites testing AI engine optimization tactics. Agencies and site owners preparing for the next phase of AI search and retrieval.
