Benchmark #1 (Verified): Google docs — "indexing isn't guaranteed"; "several days minimum… three days or more" to crawl/index for most sites (Search Central docs, last updated Dec 2025)

Claim: Google's Search Central documentation (last updated December 2025) states that crawling and indexing "take some time and rely on many factors" and that "in general, we cannot make predictions or guarantees about when or if your URLs will be crawled or indexed." Troubleshooting docs say "for most sites, new pages will take several days minimum… most sites shouldn't expect same-day crawling," and that Google "strives to check and index pages in a reasonably timely manner. For most sites, this is three days or more." John Mueller's on-record range: "several hours to several weeks" (see Realistic indexing timing — Google's own stated range is "several hours to several weeks"; Mueller suspects "most good content is picked up and indexed within about a week").

Method: Authoritative platform statements; not a sample study.

Distribution or average? Qualitative range.

Confidence: Verified.

Caveat: N/A — source, not sample. The qualitative range is the highest-rigor anchor in the table precisely because it makes no numeric claim Google can't back up.
