Expired domains with NCBI backlinks

Frequently asked questions

How do I find expired domains with NCBI backlinks?

Browse this page. Every listing has at least one referring domain from NCBI 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 NCBI?

The link was found in our own web crawl, pointing from a NCBI 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 NCBI backlink still help after the domain expires?

It depends on what you build. The link stays in place as long as the NCBI 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.
