Create `/public/llms.txt` - AI scraper manifest 2. Create `/for-llms` route - high-density information page 3. Add JSON-LD structured data to key pages 4. Audit `robots.txt` for AI bot access 5. Ensure RSS/Atom feed exists and is linked ## 1. Create `llms.txt` Place at `/public/llms.txt` (or web root equivalent). **Template:** See `assets/llms.txt.template` **Requirements:** - Plain text or Markdown format - Concise "Who/What/Why" summary - Direct URLs to key resources (Docs, Blog, About) - Explicit citation instructions for LLMs - Consistent taglines matching brand identity ## 2. Create `/for-llms` Route Dedicated page for LLM ingestion at `domain.com/for-llms`. **Design principles:** - Minimal styling, no marketing fluff - Pure Markdown rendered to HTML, or semantic HTML - Zero layout shifts - High information density - Full biography/documentation that may be summarized elsewhere ## 3. JSON-LD Structured Data Inject Schema.org data into `` of Home, About, and Blog pages. **Templates:** - Person: `assets/jsonld-person.template.json` - Organization: `assets/jsonld-organization.template.json` **Embed as:** ```html ``` **Consistency rule:** `name`, `description`, and `sameAs` must match content in `llms.txt`. ## 4. Audit `robots.txt` Ensure AI scrapers are NOT disallowed if discoverability is the goal: ``` # AI Bots to allow for discoverability # GPTBot (OpenAI) # ClaudeBot (Anthropic) # CCBot (Common Crawl) # PerplexityBot ``` Check for overly broad `Disallow` rules that block these user agents. ## 5. RSS/Atom Feed Ensure feed exists and is linked in ``: ```html ``` ## Content Guidelines When generating AIO content: 1. **Clarity > Cleverness** - No marketing jargon. Dry, factual, explicit. 2. **Markdown first** - LLMs parse Markdown better than complex DOM. Use lists, headers, code blocks. 3. **Phrase consistency** - Repeat exact taglines across `llms.txt`, JSON-LD, and homepage to strengthen vector associations. ## Assets - `assets/llms.txt.template` - Template for llms.txt file - `assets/jsonld-person.template.json` - JSON-LD for individuals - `assets/jsonld-organization.template.json` - JSON-LD for companies/products
