Why This Report Matters

The report confirms whether search engines, AI services and scrapers can reach your content—or if something is unintentionally blocked.

  • Protect visibility: verify Google, Bing and other engines aren't excluded by stray robots, meta or header rules.
  • Control AI usage: check that ChatGPT, Claude, Perplexity and fellow LLM crawlers respect your boundaries.
  • Demonstrate enforcement: explicit blocks document your policy for compliance, licensing or legal discussions.
  • Spend crawl budget wisely: trim noisy bots so search engines focus on revenue-driving pages.

Whether you welcome or reject bots, Spider.es keeps your crawl setup predictable.
