The claim
Wasting crawl budget on low-value URLs delays discovery and refresh of the pages that matter.
What the evidence shows
Google's crawl budget guidance for large sites describes crawl capacity and crawl demand, and advises reducing waste from duplicates, faceted URLs, soft errors and low-value pages so Googlebot spends its budget on important content. For sites beyond a certain scale, crawl efficiency directly affects how quickly new and updated pages are indexed. Tidy architecture and clean status codes protect that budget.
