Same IP for sites & linkbuilding - negative signal for search engines?

[qlkasdjfw]

Let's say you have 40 websites which share the same IP and you place links to them on a bunch of sites (directories, blogs), albeit on different pages on these sites.

Will search engines (google) see that they use the same IP and start having the links not-pass link juice based on that same IP?

It's not a good idea to manipulate your link profile with links that are all on the same server.  While this might give you some benefit in the short term, Google understands quite a lot about linking and will most likely catch on.  If you have taken the time and investment to build 40 quality websites, why risk getting them banned or devalued?

Google would be stupid to allow this kind of linking.  Google is not stupid.  I would recommend linking your sites together only where strictly relevant, or else use rel=nofollow.  I think that's about as clear an answer as it is possible to give.

It's highly unlikely you'd get problems from it but it's not going to get you much in terms of link juice either. It will some, just not loads... if you make sure you've got a whole bunch of links from other places too then it won't matter

Where I work, we provide hosting as well as SEO and there's quite a few sites all on the same C block that have footer links to us. They do pass some link juice, but they'd do better for us if they were hosted in other places.

There is a solution though. Funnily enough I only just found out myself today (from a Distilled Link Love seminar vid). There's hosting sites that can offer you webspace with different IP blocks and whole different locations.

A couple are: http://www.aseohosting.com/ and http://www.biggest-hosting.com/seo_hosting.html among others.

Thanks for the replies. Unfortunately I am using amazon cloud server for some sites, I'll have to look at some creative solutions to get them on different IP blocks or IP's altogether.
