# Bulk New & Lost Referring Domains

**API:** Data API

**Endpoint:** `POST /v1/beta/dataforseo/backlinks/bulk_new_lost_referring_domains/live`

**Tags:** DataForSEO

New and lost referring domains for many `targets` since `date_from`: `new_referring_domains`, `lost_referring_domains`, `new_referring_main_domains` and `lost_referring_main_domains` per target. Prefer this over `post_dataforseo_backlinks_bulk_new_lost_backlinks_live` when judging whether a site is genuinely gaining relationships - domains churn less than links. This one takes no limit parameter, so the only lever is calling it less often.
