Deindexing

What is Deindexing?

Deindexing refers to the process by which search engines like Google remove web pages or entire domains from their search index. This means that the affected content no longer appears in search results and is thus practically "invisible" to users.

Reasons for Deindexing

1. Technical Reasons

Robots.txt Blocking

  • Crawlers are explicitly excluded
  • Accidental blocking due to faulty configuration
  • Overly restrictive robots.txt files

Meta-Robots-Tags

  • noindex directives in HTML head
  • X-Robots-Tag HTTP headers
  • Dynamic blocking via JavaScript

Server Problems

  • Persistent 404 errors
  • Server timeout issues
  • DNS resolution errors

2. Quality Issues

Thin Content

  • Pages with minimal, worthless content
  • Automatically generated texts
  • Duplicate content without added value

Spam Signals

  • Keyword stuffing
  • Cloaking techniques
  • Hidden texts or links

User Experience Problems

  • Extremely slow loading times
  • Mobile usability issues

3. Manual Actions

Google Penalties

  • Manual actions by Google
  • Violations of webmaster guidelines

Warning: Deindexing can lead to dramatic traffic losses. For large websites, over 90% of organic traffic can be lost.

Types of Deindexing

1. Complete Deindexing

The entire domain is removed from the index. This is the most serious case and affects all subpages.

Causes:

  • Serious violations of Google guidelines
  • Malware infections

2. Partial Deindexing

Only certain pages or areas are deindexed, while the rest of the website remains indexed.

Common areas:

  • Admin areas
  • Test environments
  • Duplicate content pages
  • Low-quality pages

3. Temporary Deindexing

Pages are temporarily removed from the index but can be reindexed after fixing the problems.

Typical scenarios:

  • Server maintenance work
  • Temporary technical problems
  • Content updates in progress
