It seems that if a url is no longer available on a website (the website is expired so the links all 404) Majestic will mark its backlinks as deleted whether or not they exist or not still. "It is likely (if the link is still there for you) that our bot was unable to get back to the page in question, in which case we have to assume that the links on that page are also irrelevent/deleted." Link to quote: https://blog.majestic.com/development/trust-flow-yo-yo-algorithm-update-majestic/ This causes a huge issue as this will drastically drop the metrics on a domain with great backlinks still there. Maybe I'm wrong but that makes our lives a little bit harder trying to determine if an expired domain is worthwhile or not. Majestic's new update just seems pretty shit.
