Linking to one of my own sites, from my site

[KasperGJ]

Hi experts,

I own a site for castingjobs (Site1) and a site for selling paintings (Site2).

In a long time, I've had a link at the bottom of Site1, linking to Site 2. (Basicaly: Partnerlink: Link site 2).

Site1 is for me the the only important site, since it's where Im making my monthly revenue.

I added the link like 5 years ago or so, to try to boost site 2.

My question is:
1. Is it somehow bad for SEO for site 1, since the two sites have nothing to do with each other, they are basically just owned by me.
2. Would it make sense to link from Site 2 to Site 1 indstead?

Hi Kasper,

To be honest, this probably wouldn't even appear on Google's radar, but just in case, I always no-follow these sorts of links. This shows to Google that you are not trying to benefit either site in any way, even though you might prefer to do this.

A footer link won't do anything for your site and Google pretty much discounts them, but just err on the side of caution and add a no-follow.

You definitely don't want to appear as though you're running a private blogging network for links. Google's gotten way more sophisticated these days about detecting who's connected to whom, even beyond your domain registration Who.is info. That said, if your sites naturally work together, you shouldn't have much of an issue, especially if you're getting outside traffic and links.
