cool i actual bought 2 both near niche. Both clean on GSC. It is always hard to tell what they were doing. The other one is a 92DR for something entertainement. Built like a tool website with relevant and them spamming anything high DR.if the domain has a clean record and solid DR, it's definitely worth experimenting with. Just ease into it and monitor everything closely. Starting with a simple setup like you're planning is a smart move. Keep us posted on how it works out.
You can use Ahrefs tools ti check how much the reffering pages and do-follow backlinks the domain have, the more of them the more juice you get, ImoI am wondering do the 50+ DR domains have any value? The domain has no google penalites or manual actions that i can see in GSC. I am wondering am I safe to experiment and redirect it myself ? Just experimenting, maybe with a empty box using semantics
