Why robots.txt Matters for SEO
robots.txt controls which parts of your site search engine crawlers can access. Misconfigured robots.txt files are one of the most common causes of critical SEO failures — a single misplaced Disallow: / blocks all crawlers from your entire site. Google will not index blocked pages regardless of link authority pointing to them.
Conversely, failing to block admin, login, search result, and cart pages wastes your crawl budget — Googlebot spends time crawling low-value pages instead of indexing your important content. For sites with thousands of pages, crawl budget management through robots.txt is a meaningful technical SEO lever.
