- robots.txt rules for homepage, /llms.txt, pricing, and public product pages
- /llms.txt exists, is public, and has enough product/entity context
- llms.txt summary, canonical links, features, pricing, API/MCP, use cases, and comparisons
- Product, SoftwareApplication, Organization, sameAs, and Offer schema
- Meta description and Open Graph descriptions for answer-engine summaries
- Crawlable feature, pricing, API, MCP, use-case, alternative, and comparison copy
- Split scoring: Overall, Google SEO, and LLM Search

## MCP Server for Claude

The SEOBolt MCP server lets Claude and other MCP clients run audits directly. Connect the remote server (Streamable HTTP, nothing to install):

```bash
claude mcp add --transport http seobolt https://seobolt.app/mcp \
  --header "Authorization: Bearer sk_live_YOUR_KEY"
```

Or run the npm package `mcp-server-seobolt` locally over stdio, e.g. in claude_desktop_config.json:

```json
{
  "mcpServers": {
    "seobolt": {
      "command": "npx",
      "args": ["-y", "mcp-server-seobolt"],
      "env": {
        "SEOBOLT_API_KEY": "sk_live_your_key"
      }
    }
  }
}
```

Call the endpoint, get HTTP 402 with a PAYMENT-REQUIRED header (price, network, asset, payTo), pay with any x402 client, and retry with the PAYMENT-SIGNATURE header. Calls that fail (4xx/5xx) are not charged. Returns 503 while pay-per-call is not enabled. Machine-readable list with input schemas: https://seobolt.app/.well-known/x402
