  "description": "OnCrawl's SEO crawler, used to analyze a customer's own site structure and content for technical SEO reporting. OnCrawl publishes the fixed set of static addresses its crawler uses — three in the EU (Belgium), which crawls use by default, and three in the US available on request — and tells customers to allow them. The bot's name is configurable per crawl, so the user agent alone does not establish identity.",
