Similar sites on same IP address

[RichBestSEO]

Hello,

A client has a small number (3) of large price comparison sites which have been launched on separate subdomains - BUT all on the same hosting IP address.

The roll out of the sites was not ideal from an SEO perspective - as basically cloned versions of the sites were initially launched and indexed - and are only now being customised i.e. unique content added to each of the category and sub category pages.

The first site initially got some traffic - and so did the 2nd in the early days - but then they both bombed (especially number 2). So we think there has probably been some kind of slap / sandboxing. We are starting to see some very early signs of recovery now some months after.

My questions is - would it be a wise move to migrate each of the sites to a separate IP address as we start to evolve and optimise each site. Or are they ok  to be left on the same hosting / IP address?

The sites in question are :

shop.deliaonline.com

shop.ivillage.co.uk

rewards.bestforfilm.com

Thanks in advance for your help.

Richard

Having each on a unique IP isnt neccessary.

The only real benefit of having your sites on seperate Class IPs is to break the relationship between them. In your case, sorting the duplicate content issue should be enough to sort out the penalty.

The only downfall IMO would be the low link juice value from linking between all 3 sites
