Deindexing
The removal of pages or an entire domain from the search index, verifiable by a site query returning nothing.
Analogy Mental model
Not merely withdrawn from the display case, but struck from the library's master ledger entirely.
In practice What you actually do
Work through four causes in order of likelihood. First, an accident: a noindex directive or a blocking rule from a staging environment deployed to production, an expired domain, or days of downtime. Then a site-wide manual action, a copyright complaint campaign, or a canonical tag pointing at the wrong host.
Where people get burned Pitfalls
For a technical accident, fixing the code is only half the repair. Resubmit the sitemap and request indexing for the key pages individually, and expect several days before the index reflects reality.
