## Concepts

* **`target_domain`** — the domain a campaign researches backlinks for. Defaults to the website's own domain; set it to research a subdomain or partner site instead.
* **Opportunity scoring** — each opportunity carries a `relevance_score` (0–100), `domain_authority`, `domain_rating`, estimated `monthly_traffic`, and AI `reasoning` explaining why it surfaced.

<Note>
  Backlink opportunity research is triggered automatically once a campaign is created — poll the campaign's `progress` field or list its opportunities to watch results arrive.
</Note>

<Warning>
  Organization SMTP settings must be configured under **Settings** before you can send outreach emails.
