Why robots.txt gets sites deindexed
The most common SEO disaster
The most frequent robots.txt catastrophe is a developer adding "Disallow: /" to block bots during site development, then forgetting to remove it on launch. This causes an entire site to disappear from Google within days of deployment - often after a major redesign or platform migration.
Crawl budget and indexing efficiency
Search engines have a fixed crawl budget per site - they can only crawl a set number of pages per day. Allowing bots to crawl low-value pages (admin panels, filter URLs, session parameters) wastes crawl budget that should be spent on your canonical pages and new content.
