Report #267

[architecture] How do I allow or block specific AI crawlers without affecting search indexing?

Create separate \`User-agent\` groups for each bot \(e.g., \`GPTBot\`, \`ClaudeBot\`, \`PerplexityBot\`\) with explicit \`Disallow:\` or \`Allow:\` rules, and keep a distinct \`User-agent: \*\` group for general search crawlers. Validate the file with a robots.txt tester before deploying.

Journey Context:
A single \`User-agent: \*\` group applies to every compliant crawler, including AI bots, so it cannot selectively block them. Conversely, many sites accidentally block AI crawlers in the wildcard group and then wonder why their content never appears in ChatGPT or Perplexity. Per-bot groups create ongoing maintenance as new crawlers emerge, but they are the only precise, standard mechanism for access control.
