Overview
Backlink data is central to link building, competitive analysis, and domain health monitoring. But working with it manually, exporting backlink lists, checking authority scores one domain at a time, tracking which links were gained or lost, is slow and difficult to repeat at scale, especially when managing hundreds or thousands of domains.
The SE Ranking API provides structured backlink data through a single integration, including referring domains, authority scores, trust metrics, new and lost links, and full backlink lists, so teams can feed this data directly into reporting tools, outreach workflows, product interfaces, or trust scoring systems.
Who is this for
- Link marketplaces and directories that need to display domain quality metrics for thousands of listed publisher sites.
- Agencies and platforms that monitor backlink changes and trigger outreach automatically when links are gained or lost.
- Product teams using backlink authority and trust scores as quality or compliance signals inside their own platform.
What teams are building and why
Display verified quality metrics so buyers evaluate link placements with real data.
Display domain authority, trust scores, referring domain counts, and organic traffic for thousands of listed websites so buyers can evaluate link quality before purchasing placements. Marketplaces using verified data rather than self-reported metrics report that buyers make faster placement decisions because they trust the numbers.
Detect link changes and trigger outreach automatically.
Track new and lost backlinks on a schedule. When the system detects a change, such as a competitor gaining a link from a domain that has not linked to you, trigger an outreach campaign automatically. Teams using this catch competitive link losses early enough to act on them instead of discovering them weeks later in a manual review.
Filter link prospects by where the traffic actually comes from.
Filter potential placement sites by domain authority, traffic volume, and geographic traffic distribution, building targeted outreach lists that exclude sites where the actual audience does not match the client's target market. Without geographic filtering, outreach targets sites that look authoritative but reach the wrong audience.
Use backlink data as a quality or compliance signal inside a product.
Pull domain authority, trust scores, and referring domain counts into client reports, product dashboards, or composite trust scoring systems where backlink data serves as a quality or compliance signal. Teams building trust scoring for user-submitted content use backlink profiles as one input to determine whether a website is legitimate before accepting it.
Data used in this workflow
- Backlink summary data — Total backlinks, referring domains, domain authority, and trust score. Used to power marketplace quality displays, client reporting, and domain trust scoring.
- New and lost backlink data — Backlinks and referring domains gained or lost within a date range. Used to trigger automated outreach campaigns and monitor link profile changes over time.
- Full backlink list — Individual backlinks with source URL, anchor text, and authority. Used to build outreach prospect lists and analyze competitor link profiles.
- Referring domain data — Domains linking to the target, with authority scores and date found. Used to qualify link prospects and track referring domain growth.
