I am coming to renewal time for the majority of my PBN domains, I've noticed that some are TF0 - I removed some links and rankings dropped, readded and they are coming back to what they were, so TF from my experience is BS. Some are 0 index, so obviously there is no help from those but I'm adding 100s of filler articles with no links to see if it will index - I have a feeling that there is a minimum number of pages that G sees that makes them index old/aged domains again. I have seen some info about this bandied around since the past 2 updates and kinda makes sense to me. They don't like thin sites, they don't really like repurposed domains unless they look legit and have shit loads of content.
As I bought the domains not really interested in metrics, as I have said a few times on the forum, metrics can easily be inflated by SER for instance or any old spam, so I bought them off the RDs - huffpo, newspapers, TV channels etc. All of them have at least 15 really good RDs, I think the average amount of RDs was 200 but some have 10ks while others have 15. With RDs in mind, does anyone boost their PBN domains' RDs with SER? Not the PBN domains themselves but the links pointing at them? Kinda your T3s I suppose.
But, I wanted to know what are your parameters for a good PBN domain and how do you check them en-masse? I am just about to buy another wave of domains and don't want to use a seller but scrape myself with the SBox addon.
