When to Block Crawlers
Use robots.txt to keep bots away from duplicate content, staging areas, or private directories. Blocking sensitive sections protects user data and prevents search engines from wasting crawl budget on pages that shouldn’t be indexed.
Letting Important Pages Through
Ensure crawlable URLs remain accessible by using Allow directives on key paths. Combine robots.txt rules with XML sitemaps and internal links to guide crawlers toward your most valuable content.
