Google distinguishes crawl capacity from demand. Server health, known URL inventory and refresh needs matter, so a single page-count threshold cannot describe every site.
When fetching is delayed, inspect logs and crawl statistics for failures, repeated filter URLs and long redirects. Return appropriate responses for retired URLs and consolidate duplicates consistently. Sitemap submission does not promise crawl order or indexing time.
Noindex must be read from a fetched response, so it does not save crawling. Robots.txt controls fetching without guaranteeing removal from the index; blocking also prevents Google from reading a noindex rule.
