Since no1 mentioned it here it takes around 1-2 MONTHS after your PBN's content indexes for it to pass juice. Matt Diggity did a test on this in 2016, so did Charles Floate in 2017. Diggity said 36 days, Floate said its taking longer in 2017, at least from his experience.
In August I made a PBN of 25 domains, expired and auction mix. From my anecdotal evidence, some (roughly 2-3 out of 10) of my expired domains (clean wayback, anchor text profile, bought from Nargil/PBNHQ etc) aren't passing any juice, even after 2 months of being indexed. All of the auctioned domains without a drop history are working, however.
Has anyone else noticed this? (if you don't run tests don't answer this please, I am not looking for your opinion/"experience" here even if you were doing SEO before the internet started)
P.S How I test my PBNs are I create content, let it sit at least a month after indexing, then link to a competitor in your niche whos site hasn't been receiving any links, usually on page 3-4, make the link an exact match anchor, track the competitor's site for the exact anchor text I linked. Then typically one of two things happen:
1. Nothing
2. It jumps to page 2, sometimes even page 1 for that specific term.
Is there a better way/faster way to test PBN's?
