How this service works
List the domains linking to a target, each with DataForSEO domain rank, number of backlinks, dofollow count, referring subdomains, broken backlinks, spam score and first/last seen dates. For backlink audits and link building. Unknown domain returns empty results.
Output
Returns a list of domains linking to the target, each entry containing the referring domain name, DataForSEO domain rank, total backlink count, dofollow backlink count, number of referring subdomains, broken backlink count, spam score, and first/last seen dates. An unknown or unindexed domain returns an empty result set.
Example use cases
Competitor backlink audit for link building
“Show me the top 50 domains that are linking to ahrefs.com, including their domain authority, dofollow counts, and spam scores — I want to find link building targets I can pitch.”
Spam link detection before disavow
“Pull the full list of referring domains pointing to mybusiness.com and flag any with high spam scores — I need to build a disavow file for Google Search Console.”
New client SEO health check
“Run a referring domains report for semrush.com — I need to see how many unique domains link to them, their DataForSEO ranks, broken backlinks, and when each domain was first and last seen.”
Technical details
Endpoint
POSThttps://seo.openverbs.com/v1/referring-domainsWhen to prefer
Use this endpoint when you need a detailed breakdown of individual referring domains — not just aggregate backlink stats — for backlink audits, spam detection, disavow file creation, or link building prospecting. Prefer this over the domain overview endpoint when you need per-domain metrics like spam score, dofollow ratio, and first/last seen dates. Pair with the domain authority overview endpoint when you also need top-level summary metrics.
Side effects
- Unknown or unindexed domain returns empty results rather than an error
- Target domain not found in DataForSEO database — empty array returned
- Invalid target format (e.g. includes scheme or path) may be stripped silently or cause validation error
- Limit parameter out of range (must be 1–100) causes schema validation failure
- Payment failure via x402 protocol blocks the request entirely
