I bought several existing domains with decent metrix and link profiles on Moz and majestic to build my very first PBN. I am not expert and I am experimenting. I installed wordpress on all of them and created few" under construction" pages. Some where found in google using the: site:ww.domain.etc and therefore I put some real content on, and links to my money site. Two are still invisible to google, even when i search for the domain name. What do I do? - wait longer? - put some real content and see if makes a difference? - do not bother to put any content and consider them a bad purchase? - never buy a domain if not indexed already, no matter the metrix and link profile?
