Honestly, the strongest backlinks right now are the ones that are already doing something before your link even goes live. I’m talking about pages that already rank/active for a longtime, get crawled often or have some level of traffic. When you drop a link there, you’re not starting from zero, you’re tapping into existing trust.
In a lot of cases, I’ve seen one well-placed link on an active page outperform a bunch of links built on fresh or empty posts.
Most people chase metrics or link types… But from what I’ve seen, page activity > site metrics right now.
