SEO implications of several wordpress-based sites on one server?

[surrealillusions]

As per the title and description really.

Is there any SEO implications on having several sites built with wordpress on the same server? The sites are not related, although 2 or 3 maybe (out of about 20-30 total) on the server. The sites are all clients of ours, plus a some of our sites for various parts of the business.

Will google (or any other se's) look at that and think we're upto something or just see that the sites are unrelated but reside on the same server?

Any help would be appreciated :)

IF you interlink site a with b then site b with c and so on, you will have problems.

If any case, you are not-interlinking any sites no worries.
I will recommend to take each site on an unique IP Address to avoid any penalties faced by Site A to Site B (mails or dns or anything)

As stated, I would agree with the suggestion of getting unique ip's for each site. They are dirt cheap. Typically a dollar a month.

Ok cool.

Thanks for the info :)
