Technical SEO FAQ · Crawling, Crawl Budget & URL Management
Can blocking a URL in robots.txt solve an indexation problem?
Not reliably.
robots.txt controls whether a crawler may access the URL. It does not guarantee that Google forgets the URL.
Google may know a blocked URL from external links or other references and may show the URL without its content or snippet.
If the objective is to prevent a page from appearing in Search, Google recommends appropriate indexing controls such as noindex when the page can be crawled.
Therefore:
robots.txt ≠ noindex
and
crawl prevention ≠ guaranteed index removal.
