hello, i am a newbie here. In recent days i try to build some PBNs for myself. i have try to learn some useful tips from BHW and thanks for every one who help me. Now, i have meet a question about buy old domain name for my PBN. For example, 1st: i come to search the dropped domains online, found the domains pr >3 2nd: i go to ahrefs to check the domain is spamed or not. 3rd: i go to check the domains CF/TF by majestic. question: i always found the domains have pr >3, but i found no backlinks at ahrefs and the majestic CF/TF are N/A. Does the PAGERANK is True and reliable? Sorry, my bad english.
