An independent wiki host reports Google indexes only the main page of brand-new domains

Sources: primary, discussion
Summary: An independent wiki host reports that Google indexes the main page of a brand-new domain and leaves the remaining pages out of the index for months. The post, dated 2026-08-17, traces the behaviour to a Google core update in March 2024 and reports it affecting roughly 90 percent of the wikis launched on new domains since then, in some cases for up to a year. The post describes serving the same content from a subdomain of an established domain as the workaround that restored indexing. The account is one operator's observation rather than documented Google behaviour.
Why it matters: If the pattern holds, launching on a fresh domain costs most search traffic for months, and a subdomain of an established domain is the reported workaround.
