Domain age is not a ranking factor — here's the evidence

Few SEO claims are repeated as confidently as "older domains rank better." It feels intuitive — but intuition is not evidence. Let's look at where the myth comes from and what the record actually says.

Where the myth comes from

The claim is almost always traced to Google's patent US 7,346,839 B2, "Information retrieval based on historical data" (filed 2003, granted 2008; inventors include Anurag Acharya and Matt Cutts). People quote one line about domain registration data and conclude that age is a ranking signal.

But read the patent in context. It suggests the date a domain is registered may be used as an indication of a document's inception date, and that registration length could help judge legitimacy — spammers often register for only a year, while serious sites register longer. It is a discussion of possible signals to detect spam, not a statement that "age = higher rankings." Matt Cutts — a named inventor on the patent — publicly rebuffed the "domain age is a ranking factor" reading more than once.

A patent describes what a system could do. It is not confirmation that a signal is used, or how it is weighted.

What Google has actually said

Google's John Mueller has stated plainly, more than once, that the age of a domain is not a ranking factor. What correlates with older domains is not age itself but the things that accumulate over time:

• More links and references from other sites
• A longer track record of useful content
• Brand and entity signals that strengthen with exposure

A two-year-old site that has earned authority will outperform a ten-year-old parked domain every time.

The takeaway

Don't buy an aged domain expecting a ranking boost. Invest the same budget in topical coverage, internal linking, and earning citations — the signals that actually compound. Age is a side effect of doing the work, not a shortcut around it.
