When does Google *finally* remove content from search?

Hello,

I wondered when Google does *finally* remove non-existing site content from it's engine?

I've had a very well indexed site which I removed ~6 months ago, and now I've setup a new site on that domain. Now it seems that periodically the old site appears in Google (and thus a lot 404), like one weeks it's in Google, the other not.

Is this related to which Google site you get connected, or some strange effect with Google's database?

Thanks

Mostly they remove it within 3 to 6 months. How long have you changed your site ?

 

Well, it depends on Google because there is no fix time generally we say that 3 to 6 months but it is not the exact match actually....plus if the site having a unique content then the Google will save it in its data base for the long period of time....

 

you can delete the web pages in google webmaster tools ,but the final time is uncertain

 

It could take a much faster if you have done it properly. It would take not over 2 months if you have done these

1. Do 301 Redirect in each and every old indexed pages to a new page, or to root (http://www.domain.com) If you do not have a page for replacement.

2. Get your site verified with Google Webmaster Tools and submit your new sitemap.

 

Thank you for your replies. I'll will have a check in webmaster tools - something I really should have done before.

But the point is that my old content seams to appear and disappear in Google search by random. Now, when I'm checking today with site: command, I just get 5 hits - suggesting everything is out of Google now. I'm sure if I check next week I'll find fare more hits than today.... at least it's what happened the last weeks, and that's what my 404 log shows.

 

Do you have any deep links going to the old site? If so, those pages may never be de-indexed, or its going to take a few years.

I still have links showing up in my google webmaster tools that are 3 - 4 years old and google treats those pages as if they are still there. According to my google webmaster tools, I still have pages on my site that were removed almost 4 years ago. But its only the pages that are linked to.

 

There is no fix time, generally we say they remove it within 3 to 6 months but it is not the accurate time.
