both websites are for the same industry. I am being told that because the IP addresses are different and the physical server is different then there should not be a problem. I’m not sure but I would say that this is incorrect can someone please give me some advice on this?

What exactly are you looking for

If you had two websites in your PBN that looked like the above would you be concerned about footprints?

I would not even consider someone is going to spy on me that way.
I stopped believing google techniques of destroying ones business are so sophisticated.
It just doesn't seem to work like that.

Maybe there is some case study with machine learning model which concludes this can really get you down?
Until then it's just some chitchat of marketplace sellers to talk about dangerous footprints.

Sarkar's links for sure leave them all and he has 1000s of happy customers.
