Forum:A reason for NOINDEX not to work?

Hello, coming from MMD wiki.

There are pages that I marked with NOINDEX, only I am seeing no result that it is functioning. I can still see results in search engines four days later, and it didn't create the category "Noindexed pages" automatically. -- Bunai82 (talk) 18:57, November 27, 2011 (UTC)


 * Search engines have a very good memory, I'm afraid. :-( It takes a lot of time to remove pages from their grasp. -- Weas-El ✉  19:37, November 27, 2011 (UTC)
 * Crawlers (the programs indexing and searching through pages) tend to revisit a page between 10 minutes and 30 days depending on the content. If the content is static, usually the revisit is lengthy. If it's a news site, you can have a crawler come back every 10 minutes to get the content indexed. Some long time static pages can also become revisited after 90 days. More info: http://www.google.com/support/webmasters/bin/answer.py?&answer=1061943
