How long to phase out unlinked pages?

Google phases out pages that arent linked to, but how long does it take?

According to Google and some other sources I've read, Google eventually drops pages that have no incoming links, particularly subpages within your website.

We've changed our site structure, and for certain reasons can't delete the old pages. These pages aren't linked to from anywhere though, and I'm curious how long it will take Google to drop them. Or will it?

It's been about a month since the last linkage to them.

Thanks :)

P.S. Pages are dynamic and I can't add "noarchive" to them.

Probably you can do some internal linking or atleast a sitemap containing a link to that section of the page. Atleast have an entry point for a page and let spiders see where do people enter that page :-)

Would you please list where the Google words are and some of the other sources. Want to read them. Thanks.

I think he doesn't want them indexed anymore. It's sounds like you're telling him a way to get them indexed.

Another forum member suggested the following and I've found it works great. If you put <meta name="robots" content="noindex,nofollow">
in the head section of your pages I've had them removed within a couple of weeks.

Nobody wants to answer, so... three to four months.

Unless... Google indexes the pages on its own. I had some of these no link orphans, and Google came and crawled them anyway.

Thanks SteveB... you answered my question. :)

[steveb]

Yeah, but I hope you don't ignore the second part of the answer. I have a page that has been orphaned since mid-October, and it is still showing as a supplemental result.

I redesigned a site last November and removed all the links, and then in first week of January removed all the unliked pages. The pages still come up in the G serps even though they've not been around for almost two months.
