De-index means removing the content from the eyes of the search engine so that it’s not searchable using search queries. If your content is de-indexed, it’ll not appear in Google (or similar search engine) results.
De-indexing is different from deletion as deleted content is never retrievable but de-indexed content still exists online, just that it is not visible to users. Some cases employ de-indexing while others may want to opt for deletion. We collaborate with you to figure the best strategy for your business and case.
