The Domain Archive Project is an independent, open-access research initiative dedicated to cataloging and analyzing expired, dropped, and historically significant internet domains. Our database tracks domain authority metrics, backlink profiles, spam scores, and historical trend data across thousands of domains that have lapsed registration.
Mission
The internet's domain landscape is constantly shifting. Every year, hundreds of thousands of domains expire — including government portals, educational resources, news outlets, and institutional databases. When these domains lapse, their accumulated authority, backlink profiles, and historical data become orphaned. Our mission is to preserve this metadata before it disappears entirely.
Why This Matters
Expired domains with high authority scores are frequently acquired by bad actors for private blog networks (PBNs), spam operations, and manipulation of search engine rankings. By maintaining a transparent archive of expired domain metrics, we aim to:
- Provide researchers with historical domain authority data for academic study
- Help SEO professionals identify domains with suspicious backlink patterns
- Document the lifecycle of internet domains from registration to expiration
- Track PBN footprint indicators across expired domain clusters
- Preserve institutional knowledge that would otherwise be lost
Data Integrity
All metrics in our database are sourced through automated crawling and cross-referenced against multiple third-party data providers. We update our records weekly and maintain historical snapshots dating back to 2021. Our methodology page provides full technical details on our data collection pipeline.
Open Access
This database is freely accessible to researchers, journalists, and security professionals. We believe that transparency in domain metrics serves the public interest by making it harder for bad actors to operate undetected. All data is provided as-is for research purposes.
