BL means "backlinks" -> the number of total links the domain have. However whats important is how many links from unique domains you have and this is the DP (commonly called RD). So DP is whats important, BL is completely useless metric for you. Fair warning - all those domains are spammed to death. If you think that you can find clean, good domains with "millions" of links in expireddomains... well, you cannot.Let’s say that i found expired domains in my country with millions/hundreeds of thousands of BL that i am able to buy them cheap. (Just expired and available for purchasing).
But i don’t know What is more important. BL or DP?
I'm new to this, but when buying an expired domain, consider these factors: Backlinks (BL) quality and relevance. Domain authority (DA) and PageRank (PR). Trust flow and citation flow. Spam score. Domain age. History and reputation. A well-chosen domain can boost your rankings.When you buy an expired domain What is the most important thing that you’re looking for? BL / DP ( i don’t know What it is) / ABY (the Same).
Can help me with rankings if i buy expired domains and create posts on them with linkins to my Main website?
