Frequently Asked Questions
What is the purpose of robots.txt?
Robots.txt instructs web search engine crawlers which URLs and directories on your website they are permitted or forbidden to access.
Does robots.txt hide sensitive pages from being indexed?
No, robots.txt prevents crawling, but if a page is linked externally it can still be indexed. Sensitive pages must use noindex meta tags or authentication.
