I have a website that is about 9 months old with 65 post. I haven't build any links to it, just letting it age. A few days ago, i found an expired domain that used to be a news site with great links coming from other huge news site. At first, i'm going to add this site for my PBN but since this site used to be a legit news site, so now i'm thinking to move my site to this domain. So here's my question, i recently build links to the old site, not much, just a couple. After 301 redirect to the expired domain, should i build links right away or wait a few weeks to let it settle down a bit?
