Backlink Monitor

Web & SEO Tools

Operated by Sourcelane✓ verified

Track new and lost backlinks for any website. Schedule it daily or weekly to get each link gained or lost since the last run, with anchor, domain rank and spam score.

Read full description

A scheduled backlink monitoring connector that detects and reports only newly gained or recently lost links for specified websites by comparing each run to the previous run. It performs incremental change detection using stored per-site state, crawls and inspects linking pages to extract linking page URL, linking domain and title, the target page on the monitored site, anchor text and link attributes (dofollow / nofollow / sponsored / UGC), link type, domain and page authority scores and a spam score, source country/language and content platform type (blog, news, forum, etc.), and timestamps for when links were first and last observed. Outputs are organized as one record per detected change (gain or loss) and include per-website totals of new and lost links; the connector supports scheduled daily/weekly runs, deduplication and filtering by link attributes, authority and spam thresholds, and limits on links returned with results sorted by strength.

Calling contract

Call it through Sourcelane's gateway or MCP server. We run the connector, apply your agent's spend guardrails, and bill only the results returned.

Call it via Sourcelane

curl -X POST https://api.usesourcelane.com/v1/call \
  -H "Authorization: Bearer sl_live_your_agent_key" \
  -H "Content-Type: application/json" \
  -d '{"listing":"backlink-monitor","params":{"targets":["stripe.com"]},"maxResults":10}'

Request params

Field	Type	Required	Description
`targets`	array	required	Domains (example.com) or full page URLs, one per line (up to 100). A domain includes its subdomains; a URL with a path tracks only that page.
`changes`	string	optional	New backlinks, lost backlinks, or both.
`sinceLastRun`	boolean	optional	On a schedule, report only links gained or lost since this website was last checked, so you never see the same change twice. The first run of each website uses the lookback window below.
`lookbackDays`	integer	optional	How far back to look on the first run (or every run when the option above is off). Up to 90 days.
`oneLinkPerDomain`	boolean	optional	Report only the strongest new or lost link from each linking site, so one site adding 500 links shows as one row. Turn off to list every link.
`dofollowOnly`	boolean	optional	Ignore nofollow links.
`minDomainRank`	integer	optional	Only report links from domains with a domain rank (0-100) at or above this value. 0 includes everything.
`maxSpamScore`	integer	optional	Leave out links with a spam score (0-100) above this value. 100 includes everything; 30 hides most spam links.
`maxResultsPerTarget`	integer	optional	Maximum new links and maximum lost links to return for each website, strongest first. Up to 20,000.

Each result contains
