How long does it take for Google to de-index urls?

[nicole.healthline]

Added the noindex meta tag to some pages on my site and I am wondering if anyone has any idea how long it will take to deindex the urls?

The time it would take for your pages to be de-indexed vary from site-to-site.

It is based on how frequently your site is crawled, how often those particular pages are crawled, and when the last time those pages were crawled.

If it is important you can log into Google Webmaster Tools and request for the page to be removed from Google's index.

Google won't give a specific time table as to how quickly they would update.  We would all hope the next time they re-crawl that specific page and then shortly after that update the index, but examples have shown it's not quite that fast.  If you have registered your Google Webmaster Tools account you can go under "Site Configuration" -> "Crawler Access" -> "Remove URL" and send them an actual request that you would like it removed from the index.  This will help expedite the process.

I would also speed up your crawl rate with Google in GWT.  Yes, you can remove certain pages, but Google will need to re-index all the other pages that use to link to them.
