Frequently Asked Questions
What Traffic Patterns Should I Expect From OnCrawl Mobile?
OnCrawl Mobile usually performs comprehensive, link-following crawls rather than spot checks. Visit frequency may rise while a customer actively monitors your site or a related market.
Does OnCrawl Mobile Follow Robots.txt Rules?
OnCrawl Mobile is expected to follow robots.txt rules, so a disallow rule is the appropriate first step if you want to block it. Automatic Robots.txt can add and maintain that rule, while Agent Analytics lets you verify whether OnCrawl Mobile respects it.
Is OnCrawl Mobile Used for AI Model Training?
Not ordinarily. OnCrawl Mobile is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking OnCrawl Mobile Affect AI Search or Citations?
Not directly. OnCrawl Mobile's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does OnCrawl Mobile Access Private Content?
No. OnCrawl Mobile can reach only public pages, and authentication prevents it from accessing private content.
How Can I Verify a Request From OnCrawl Mobile?
Agent Analytics tracks OnCrawl Mobile visits in real time. You can also check your server logs for requests whose user-agent string contains "OnCrawl Mobile". Look for comprehensive site crawls that follow internal links. Because OnCrawl Mobile does not publish a verification method, any client can claim its identity and a log match is only a clue.
