Frequently Asked Questions
What Traffic Patterns Should I Expect From MBCrawler?
MBCrawler 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 MBCrawler Follow Robots.txt Rules?
MBCrawler 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 MBCrawler respects it.
Is MBCrawler Used for AI Model Training?
Not ordinarily. MBCrawler is not categorized as an AI training scraper or data provider, so AI model training is not its expected purpose.
Does Blocking MBCrawler Affect AI Search or Citations?
Not directly. MBCrawler's expected purpose is not to supply an AI search index or retrieve pages for AI-generated answers.
Does MBCrawler Access Private Content?
No. MBCrawler can reach only public pages, and authentication prevents it from accessing private content.
How Can I Verify a Request From MBCrawler?
Agent Analytics tracks MBCrawler visits in real time. You can also check your server logs for requests whose user-agent string contains "MBCrawler". Look for comprehensive site crawls that follow internal links. Because MBCrawler does not publish a verification method, any client can claim its identity and a log match is only a clue.
