I am currently working on a multi-niche authority site (100+ pages up to now but aiming on a few 1000). I have found a way of finding 1000's of expired domains with very high quality links from major tech/news sites and have been building a PBN using them however, as I want to cut down the costs as much as possible and I am only working on this site for the next 6 months, I was thinking of buying a few of these expired domains and redirecting them to my homepage, so I dont have to pay for multiple hosts. I have done some research on the effects of boosting rankings via this method however there seems to be alot of mixed views on this. I have never tested it for myself so I dont know the answer myself, but if anyone else can answer if I could see a ranking boost from this please let me know. A few details about the domains and my site: The domains are in the same broad niche as my site (both tech sites but not targeting the same kws) The domains have no spammy links My site is fully siloed so the juice going to my homepage will flow to all pages (5 silos, 2/3 levels deep, linking back to top of silo) Domains have DA/PA of avg 20/30 and trust/citation flow of avg 15/15 What do you guys think? Should I redirect them?
