Clean up index infection

Foreign subpages in the Google index

With a so-called Japanese Keyword Hack, foreign search results appear under your own domain, often with Japanese characters, product names, or shop content. The content can be generated dynamically and therefore be missing from the normal WordPress page overview.

I identify and remove the code causing the issue, check Search Console for unauthorized changes, and submit the affected URL patterns for removal.

How an index infection may be set up

The specific implementation varies depending on the incident. In particular, the content served, sitemaps, access credentials, and the WordPress installation are checked.

Different content for search engines

The server can serve different content to search engines and regular visitors depending on the browser identifier or origin.

Additional sitemap

An unknown sitemap can submit many foreign URLs to Google and speed up their inclusion in the index.

Unknown Search Console access

An additional verified user can submit sitemaps or change settings and must be checked.

No posts in the backend

Dynamically generated URLs do not appear as regular pages or posts in WordPress.

How to clean up the Google index

1

Record affected URL patterns

I analyze search results and Search Console and document which URLs and patterns are affected.

2

Remove the code generating the pages

Server rules, PHP files, extensions, and the database are checked. Any malware found is removed and the identified entry point is closed.

3

Check access credentials and sitemaps

Unauthorized users, unknown sitemaps, and manipulated settings in Search Console are removed or corrected.

4

Initiate removal from the index

The affected URLs return an appropriate error status and are submitted for removal using the Google procedures available.

Frequently asked questions

Why do I see different content when I access the page than Google does?

Manipulated code can evaluate the browser identifier, origin, and other characteristics of the request. I therefore test the affected URLs under several controlled conditions.

The technical cleanup is completed within 6 hours once all required access credentials have been provided, Monday to Friday from 8 a.m. to 8 p.m. How long Google takes to reprocess all affected URLs or remove them from the index depends on the scope and crawling.

The impact depends on the scope, duration, and Google's assessment. After the technical cleanup, the affected URLs and security status continue to be monitored; a specific ranking outcome cannot be guaranteed.

The cleanup costs €280 net at a fixed price. A preliminary assessment for €50 net is credited toward the subsequent cleanup.
