About this list
The Columbia University link is found, not claimed. Referring domains are counted from our own web crawl, not from a paid link index. Availability is re-checked against the live DNS root over DNS-over-HTTPS, and a listing that turns out to be registered is removed. Site history comes from archived captures: the archived snapshot count and the span of years the site was captured. Revised Score blends link-graph centrality, referring domains and site history into one 0 to 100 grade, computed across the whole directory.
A link from Columbia University is one signal. Read it alongside the referring domain band, the site history and the Revised Score on each listing, and browse the other sources for domains linked by universities, encyclopedias, communities and press.
Frequently asked questions
- How do I find expired domains with Columbia University backlinks?
- Browse this page. Every listing has at least one referring domain from Columbia University in our web crawl, has expired, and is available to register. Names are masked on Free, the Starter and Business plans show every name, and metrics are open. Starter and Business show the name; then register it at any registrar.
- How do you know a domain has a link from Columbia University?
- The link was found in our own web crawl, pointing from a Columbia University page at the listed domain. The graph is a snapshot of the crawl at the time it was built, so a link removed since then can still appear until the next snapshot is processed.
- Does a Columbia University backlink still help after the domain expires?
- It depends on what you build. The link stays in place as long as the Columbia University page does, and it resolves to whatever is at the domain now. Google's expired domain abuse policy targets expired domains repurposed for unrelated content, so a site that continues the old domain's subject keeps the benefit and one that changes subject should not expect to.
