An expired domain is a domain whose registration has lapsed and which — after the relevant protective period — becomes registrable again. They are interesting because of existing history, possible backlinks and an established name. Whether reactivation is worthwhile depends on vetting, legal status and the TLD.
What expired domains are
Expired domains are domains whose registration was not renewed. Until they can be registered again, they go through a deletion or quarantine phase depending on the extension. The way to secure them is domain catching.

Vet before registering
Whether an expired domain can be registered depends on its status at the registry; whether it is worthwhile depends on vetting. Relevant criteria include domain history, the quality and origin of backlinks, topical relevance and an unencumbered past. See vetting expired domains.
Realistic expectations instead of myths
Blanket claims like "guaranteed SEO boost" or "Google prefers expired domains" are not reliable. A domain with a clean, on-topic history can bring advantages — but need not. More under expired domains & SEO and risks.
TLD dependency
Deletion cycle and availability differ significantly by extension. Start with .de or pick your extension in the TLD guides.
Frequently asked questions
Are expired domains automatically good for SEO?
No. A search engine does not prefer expired domains in general, nor does history guarantee an advantage. Backlink quality, topical relevance and a clean past are decisive — and must be checked.
How does this differ from domain catching?
Expired domains describes the object (lapsed domains); domain catching is the process of securing them at the release moment.
