Welcome to the Q&A Forum

If you add the rel-tag to the master page then no. But, if you want them to rank for color and size and have a unique section of content let them stand along. If you are not seeing major declines in traffic and you say they are indexed. I would keep it as it. You don't get hit for duplicate products but you will if the pages are gateway Keyword pages.

Hi Amber The server or IP address has little to no effect on SEO. Your biggest concern is having a server that is close to your audience in terms of geographic location, that it is fast, and that you are not encumbered by the traffic to any other sites sharing the same IP. For this reason, always go for a dedicated server which will have it's own unique IP and SSL certificate. Locate the second site on a separate server. The fact that they share the same neighbourhood or range of IP's is irrelevant. We have covered this before so this thread might be of interest to you: https://moz.com/community/q/ip-address-of-server-an-seo-factor I hope that helps, Kind Regards Nigel

Awesome looking forward to seeing you back next year! You have a great weekend

The crawler is designed to emulate the Google crawler's behavior. It isn't perfect, but crawlers will follow all the links they can. If you require more details, an example URL with the specific links you are inquiring about would be helpful.
