Why is this not working? Google indexes pages even when "noindex" used.

Hey all

I just came across this post: http://www.mashgeek.com/partially-indexed-pages/1215/

It explains a method of preventing google from indexing certain parts of a page. The concept is simple: use iframe, linking to the page, and make sure the page has the noindex meta tag.

Now, the page that the author use (http://img.mashgeek.com/2012/06/noindex.html) has the noindex tag, but the content is still indexed (the page is not.). This doesn't make any sense.

Anyone can provide more insights here?

Thanks

The issue may be that the page was previously indexed and Google has not updated it's index with the new information...

In any case, you can manually remove pages using Google Web Master Tools, and or make use of a robots.txt file.

From what I can see the author created the page at the time of writing the post. So the noindex tag was always in the page. No way Google could have indexed it before the post going live. This is getting interesting now..
