DropDomainsList is a free tool that helps SEO professionals, domain investors, and webmasters find expired and dropped domains across 70 niche categories. Unlike paid tools that charge hundreds of dollars per month, we provide verified domain data completely free of charge.
Every domain in our database has been sourced from real web crawl data, verified through DNS and WHOIS checks, and enriched with authority metrics from Open PageRank and historical data from the Wayback Machine.
Our automated pipeline runs daily to discover, verify, and enrich expired domain data:
We scan Common Crawl S3 CDX index files — one of the largest public web archives — to identify domains that were previously active across our 70 niche categories.
Each domain is checked via DNS lookup and WHOIS query to confirm it is genuinely expired and available for registration. We run full WHOIS verification weekly to minimize false positives.
We enrich each domain with Open PageRank (OPR) scores — a free, open alternative to Google PageRank that estimates domain authority based on backlink profiles.
We retrieve original page titles, descriptions, and snapshot counts from the Wayback Machine so you can understand what each domain was used for before it expired.
We check whether expired domains still have pages indexed in Google — a strong indicator of residual SEO value.
Have questions, feedback, or want to report a domain that shouldn't be listed? We'd love to hear from you.
We typically respond within 2 business days.
