Frequently Asked Questions
Guide to Robots.txt Validation
What is Robots.txt Validation?
Robots.txt validation is the process of checking your robots.txt file for syntax errors, logical issues, and best practice violations. A valid robots.txt ensures search engines can properly read and follow your crawling instructions.
Why Validate Your Robots.txt?
Syntax errors in robots.txt can have serious SEO consequences. A single typo might block Google from indexing your entire site, or fail to prevent crawlers from accessing sensitive areas. Validation catches these issues before they affect your search rankings.
Common Validation Errors
- Placing Disallow or Allow before any User-agent directive
- Using relative paths instead of absolute paths starting with /
- Putting relative URLs in Sitemap directive instead of full URLs
- Using non-numeric values for Crawl-delay
- Typos in directive names (e.g., 'Dissalow' instead of 'Disallow')
- Missing colons after directive names
