yeah i’ve been testing them recently and here’s the real deal:
old backlinks can still pass value, but it’s not automatic. if the expired domain’s profile is clean and contextually related, google still uses that history as trust signals. you can see faster movement vs fresh domains in the same niche.
but if the profile is messy or irrelevant, google basically ignores most of it and sometimes treats it as a clean slate anyway. google isn’t “neutralizing everything”, it’s just better at identifying mismatches and low-value anchors.
so expired domains still work, but only when the history + topical relevance actually makes sense. they’re proximity accelerators, not magic ranking pills.
