in your inbox first.
Watch competitor redirects, expiring backlink-rich domains, TLD migrations, and new registrations in your niche. The change-detection layer that fits behind your Ahrefs and Semrush dashboards — not another tool to keep open.

Four ways SEO pros use this
Real workflows, not feature checkboxes.
Catch expiring domains with the backlinks you want
You've been eyeing a niche domain with great referring domains. We watch its expiry, renewal status, and registrar moves — you get the heads-up before drop pools heat up. Backorder, drop-catch, or just be ready when it goes live.
See competitor 301-redirect changes the day they happen
A competitor consolidates a subdomain or migrates a content cluster to a new path. DNS records, nameservers, and WHOIS shifts are the first public signal. Watch their domain — get the alert — check their pages before their next crawl picks it up.
Detect TLD migrations that move rankings
Brand moving from .net to .com? Local site adding ccTLDs? Watch the variants. Nameserver and DNS changes flag migration prep weeks before the new domain ranks. Adjust your content and outreach accordingly.
Brand new niche registrations as a discovery signal
Watch keyword-rich domains in your niche. When one is freshly registered or transferred to a new owner, that's a new entrant or a sale you should know about. Pair with the marketplace tracker for full deal flow.
Common questions
Does Domain Details replace Ahrefs or Semrush?
No. Those tools are for backlink and ranking analysis. We're the change-detection layer underneath them — the signal that the domain shifted hands, redirected, or expired. Use both together.
How fast are alerts?
Three checks per day per watched domain. Email goes out within minutes of detection. Fast enough to act before competitors notice.
Can I bulk-add domains from a CSV?
We have a free bulk lookup tool that handles up to 100 domains per query. For watching, add up to 25 to your watchlist on a single Alerts subscription. Larger lists — check Enterprise.
Can I integrate this into my own reporting?
Yes. Domain Details has an API and an official npm package — lookups, RDAP, DNS, marketplace pricing. The watchlist UI lives at /pro, but you can pull real-time data into dashboards yourself.
