Temporarily or permanently becoming de-indexed from a directory or search engine.

De-indexing may be due to any of the following:

  • Pages on new websites (or sites with limited link authority relative to their size) may be temporarily de-indexed until the search engine does a deep spidering and re-cache of the web.
  • During some updates search engines readjust crawl priorities.
    • You need a significant number of high quality links to get a large website well indexed and keep it well indexed.
    • Duplicate content filters, inbound and outbound link quality, or other information quality related issues may also relate to re-adjusted crawl priorities.
  • Pages which have changed location and are not properly redirected, or pages which are down when a search engine tries to crawl them may be temporarily de-indexed.
  • Search Spam:
    • If a website tripped an automatic spam filter it may return to the search index anywhere from a few days to a few months after the problem has been fixed.
    • If a website is editorially removed by a human you may need to contact the search engine directly to request reinclusion.
