I do a lot of affiliate marketing and have a dedicated server.
On the server, I have over 400 affiliate store sites (with different domains) using Wordpress, each selling different products, but most with the same general set-up/layout/template. I have tried to add individual content wherever possible, but generally the layouts are the same (with different products, title tags, etc).
My obvious question is relating to Google and how they see this.
Are the sites likely to be penalised for this in some way for being hosted on the same server?
Cheers in advance.
