When I use PBN as T1, do I need the old domain?
I would first do some serious reading on PBNs. Otherwise you will be just burning money.
Seriously ?
What authority or benefit does a brand new domain have to be able to provide any link juice?
I don't see anyone saying to use new domains, I am not sure what reasoning there would be that would put a new domains' value above a half decent expired domain .
If you use new domains your PBN won't have any power for a long time and it will be a lot of effort. I am sure a PBN can be built and be effective on new domains but you have to put in all of the leg work and will likely spend a huge amount of time and money on building it up.

For your reference here is a result how my ranking changes when I use 1 fresh domain PBN powered up with auto-created T2 backlinks.
Maybe the reason you deny it is much is that you have actually never tested it or you rank this way yourselves and don't want others to get to know that it actually works very well?
I usually don't get into conversations like this any more as people don't want to believe facts anyway, however SEO is testing. Testing is everything.
Fyi I never called anyone an idiot.Some time ago when I was a newbie I created the same thread.
And I got the same answers from you guys here.
My question is why are you guys so persistent saying a person using new domains as a PBN must be an 'idiot' ?

100% agree, I have started doing something very simialr too although I call it a bridge network rather than a PBN and have seen similar if not better results to you but I have 25 domains rather than just the one.
Fyi I never called anyone an idiot.
I think if you read what I posted you would see that I said they could work but would be more work and cost more. You even stated that you propped the domain up with backlinks, therefore you put work into it.
The whole point of expired domains is they already have the links and authority, you don't need to put the effort in, therefore are better
Buying fresh domains for your PBN, its bound to become a thing![]()
or you could say blackhat does not work...funny thing is even some white hat people offer pbn services...Just as dozens of "PBNs no work!!1!!!" threads.
