Robots.txt for SEO
Robots.txt for SEO is not about tricking algorithms—it is about budget. Search engines allocate a crawl budget per host; when faceted navigation generates infinite URL variants, you burn that budget on duplicates instead of fresh articles or inventory updates. A disciplined Disallow strategy (often paired with parameter handling in Search Console) keeps crawlers focused on URLs that earn revenue or backlinks.
This page still loads the full SmartFlexa editor so practitioners can prototype rules while reading SEO-framed guidance. Remember that blocking a URL with robots.txt does not remove it from the index if it was already discovered; combine with noindex or removals when the goal is suppression, not merely crawl savings.
