Deindexing and deletion are not the same
Deleting or correcting the source is the strongest outcome because the content disappears for direct visitors and search crawlers. Deindexing hides a result for specific engines or queries but may leave the source online and accessible by URL.
The plan therefore starts with the publisher, platform, host, or right that can change the source. Search-engine routes are used where the source is already gone, exposes protected data, infringes rights, or meets another documented removal category.
