I’m not a “veteran” in SEO; I only started doing this not too long ago, and I came across a network of over 1,000 links to defunct websites. I collected the API keys from each link and decided to see what would happen if I took a completely new domain, filled it with content, and left links from that defunct site. I was pleased with the result—in just 2–3 weeks, the DA on my sites rose to 20–25. Please advise on how to use this effectively, not from the perspective of monetizing traffic, but from the perspective of improving the system’s efficiency. I can also share backlinks; feel free to message me.
