Serve Markdown

AI agents from ChatGPT, Claude, Perplexity, and others read your content to generate answers — but they parse through HTML, JavaScript, and navigation just to reach it. Serve Markdown gives them a direct path: clean Markdown with structured metadata. When a crawler requests it — via an Accept: text/markdown header or a .md URL — your site responds instantly. No noise, no guesswork. How It Works Serve Markdown adds three capabilities to your WordPress site: 1. Content Negotiation When an AI crawler sends Accept: text/markdown, your site returns Markdown instead of HTML — no URL changes needed. 2. .md URL Suffix Append .md to any post or page URL (e.g. example.com/my-article.md) to get the Markdown version directly. 3. Markdown Auto-Discovery Every page includes a <link rel="alternate" type="text/markdown"> tag in the HTML head so crawlers can find your Markdown automatically. What the Markdown Output Looks Like Every Markdown response includes YAML frontmatter with structured metadata followed by your post content. Here is a real example: --- url: 'https://akumarjain.com/textexpander-year-in-review-2025/' title: TextExpander Year in Review 2025 author: name: Ajay url: 'https://akumarjain.com/author/akumarjain/' date: '2026-01-05T09:05:00+05:30' modified: '2026-01-10T14:30:06+05:30' type: post categories: - 2025 - Year in Review tags: - '#ToolsIUse' - Productivity - Remote Work image: 'https://akumarjain.com/wp-content/uploads/text-expander-year-in-review-2025.webp' published: true --- # TextExpander Year in Review 2025 In my daily work, I need to type the same words and phrases repeatedly...

Performance Markdown conversion only runs when specifically requested — regular visitors see the same HTML pages they always have. The crawler log uses a lightweight custom table with three safeguards against unbounded growth: time-based retention, a row count cap, and a table size cap. Privacy The crawler log stores IP addresses and user-agent strings from Markdown requests. This data stays in your WordPress database and is never sent to external services. You can disable logging entirely, configure a retention period, or clear the log at any time from the settings page.

1. Upload the serve-md folder to /wp-content/plugins/.
2. Activate the plugin through the Plugins menu in WordPress.
3. Go to Settings > Serve Markdown to configure.
4. Visit any published post URL with .md appended to verify it works.

No additional server configuration is required. The plugin works with all standard WordPress permalink structures.
