Frequently Asked Questions
What is robots.txt?
Robots.txt is a text file placed at the root of a website that tells search engine crawlers which pages they can or cannot access. It's a key part of technical SEO.
What happens if I don't have a robots.txt?
Without a robots.txt file, search engines will crawl all accessible pages on your site. While this is usually fine, a robots.txt gives you control over what gets crawled.
Can robots.txt block pages from appearing in Google?
Robots.txt can prevent crawling, but it doesn't guarantee pages won't appear in search results. For true de-indexing, use the noindex meta tag.
