Does using Wordpress Multisite have any negative SEO impact?

[JonathanFashbaugh]

I manage multiple websites in Wordpress and the idea of managing them all under one Wordpress install is very attractive. Are there any dangers SEO-wise to doing so? I know that all of the sites would live under the same IP address, but that's not something I'm really concerned with anyway because I don't do a lot of inter-linking between the sites. Thanks for your help!

If you're still looking for advice, you might want to ping @graywolf on Twitter. I believe I see him talking about having a lot of WP sites and he might have some experience or words of wisdom to pass along.

It's just such a headache updating Wordpress across multiple sites all the time! Do you really think that the separate IP addresses bring much benefit? I can do that too, but just didn't know if the added expense would really pay any dividends. I wonder if you could still set up separate IPs if you set up multisite?

If it's what wordpress says and is like having your own wordpress.com then there should be no issue.It sounds like the sites would all be subdomains of your network wordpress install.

But at the same time, I would say that if you are worried about seo and ranking I would do a separate install. And would eve go as far as to give them all their own dedicated IP.
