The Domain Archive Project is an open-access research database focused on expired and dropped domain intelligence. Its archive tracks 1,136 domains across 15 categories, with records spanning 2021–2026 and new data batches added weekly. The project provides metrics and historical information including Domain Authority, Domain Rating, spam scores, backlink profiles, and backlink decay patterns. It also examines potential private blog network (PBN) footprints, such as shared hosting IPs and repeated WHOIS patterns.

Users can explore categorized collections covering former government, education, finance, health, media, nonprofit, technology, legal, e-commerce, and infrastructure domains, among others. Each category includes domain counts and descriptions of the types of sites and backlink histories represented. The site highlights domains with high authority and lists their authority scores, backlink counts, and categories. Visitors can browse the full archive, review the project’s methodology, inspect recent data batches, and download or export raw dataset information. Data alerts are also available for users who want notifications when new domain batches are archived.
