SEO Fundamentals
Domain age is the zombie factor of SEO: officially dismissed by Google for well over a decade, forever resurrected by domain marketplaces selling "aged" domains at a premium and by the stubborn observation that old sites do, in fact, dominate most SERPs. Both facts are true, and the resolution is simple once stated: age itself is worth nothing; what accumulates during the years is worth almost everything. Here's the evidence, the confusion it untangles, and what to actually do about it.
What Google says, and has kept saying
Google's public statements are unusually consistent on this one: domain age is not a ranking factor; registration length is not a ranking factor; the difference between a six-month and six-year-old domain, as such, is "nothing." The famous ancient patent mentioning historical domain data — the myth's usual citation — described spam detection, not a seniority bonus. In twenty years of updates, no credible test has isolated age paying rank while holding everything else constant.
Why old sites win anyway: the correlated cargo
Old domains outrank young ones for the same reason forty-year-olds out-earn twenty-year-olds — not birthdays, accumulation. Years of operation typically carry:
- A link profile compounding since forever — the heavyweight factor, per the hierarchy, and the one that takes longest to replicate.
- A content library with age-in-index — hundreds of URLs, each with its own ranking history, engagement record and internal link position.
- Entity and brand recognition — branded search volume, knowledge-graph presence, mentions across the web.
- A behavioural track record — the trust history a new domain simply hasn't had time to write, per the cold-start mechanics.
Every one of these correlates near-perfectly with age and is causally responsible for the rankings age gets credited with. The proof by counterexample is everywhere: ten-year-old domains with no links and no content rank for nothing; three-year-old sites that accumulated aggressively out-rank domains twice their age daily.
What this means in practice
Don't buy age; buy accumulation — carefully. An "aged domain" with no relevant history is a birthday certificate; one with real links and clean history is an expired-domain play, valued for its cargo and audited for its scars — the age line on the invoice should be worth zero either way. Don't wait for age; start accumulating. The correct response to "old sites win" is to begin the clock: publish against mapped demand, earn referring domains, build the brand footprint — the from-zero sequence. Three years from now your domain will be "aged," and whether that means anything depends entirely on what these next three years deposit. And don't fear young. New domains win winnable fights immediately — long-tail queries, gaps incumbents ignore — which is how every old winner started.
Frequently asked questions
Does registering my domain for 10 years help SEO?
No — Google has denied registration length as a signal explicitly, and the idea never made sense (spammers can afford decade registrations too). Register long for convenience and to avoid accidental expiry; expect zero ranking effect.
If I rebrand to a new domain, do I lose my "age"?
You lose nothing that mattered and risk plenty that does: the accumulation — links, history, entity recognition — transfers substantially through a proper migration (exact 301 map, Change of Address), though domain moves settle slower than same-domain changes. The casualty in bad rebrands is always the redirect map, never the birthday.
How old does a domain need to be before it can rank competitively?
Wrong variable — the honest question is how much accumulation the target keywords demand, which is the difficulty and authority math. Sites cross competitive thresholds at eight months or never, depending entirely on deposit rate: content on cadence and links compounding — the second being the deposit most sites under-make (our deposit desk, open now). Time is just the container.
