Public Link Integrity & Redirect Audit Agent

Audit public webpage links for broken targets, redirects, blocked responses, and change evidence without running a broad crawler or browser session.

The Actor fetches the supplied public page URLs, extracts anchor links, checks a bounded number of unique public HTTP/HTTPS targets, and returns an agent-friendly integrity record with counts, samples, diagnostics, confidence, completeness, and a stable link-audit hash for change tracking.

How To Use It

For a first-pass link integrity audit, provide public page URLs and keep the default bounded checks:

{
  "urls": ["https://apify.com/"],
  "previousLinkAuditRecords": [],
  "maxLinksPerPage": 20,
  "includeExternalLinks": true,
  "requestTimeoutSecs": 15
}

Set includeExternalLinks to false when you only want to check links that stay on the same website. Keep it true when the customer task is to catch broken outbound references, partner links, documentation links, or redirecting external calls to action.

For repeat monitoring, pass previous dataset records from this Actor in previousLinkAuditRecords. If the link-audit hash is unchanged, the record is written as changeStatus: "unchanged" without the useful event charge.

What It Finds

Useful evidence can include:

• total, checkable, internal, external, skipped, OK, redirected, broken, blocked, and error link counts
• broken-link, redirect, and blocked-link samples
• per-link status results for the bounded checked set
• link integrity score, confidence score, completeness score, diagnostics, and evidence URLs
• stable link-audit hashes for repeat monitoring

Pricing

Pay-per-event pricing is designed to stay predictable:

• apify-actor-start: a tiny run-start fee
• useful-link-audit-result: charged only for useful public link-audit records
• no apify-default-dataset-item

Invalid inputs, duplicate equivalent URLs, private-network targets, query/fragment/token inputs, failed page fetches, pages without checkable links, blocked-only checks, unchanged records, and error records do not charge the useful event.

Output

Each page returns one record with fields such as:

• status, changeStatus, inputUrl, finalUrl, and siteOriginUrl
• checkedLinks, okLinks, redirectedLinks, brokenLinks, and blockedLinks
• linkIntegrityScore, brokenLinkSamples, redirectSamples, and checkedLinkResults
• linkAuditHash, previousLinkAuditHash, confidenceScore, completenessScore, missingFields, and diagnostics

The Actor uses lightweight HTTP status checks. It classifies 401, 403, and 429 as blocked rather than broken, because those targets may be valid but not publicly checkable from the runtime.

Boundaries

This Actor is a focused public link-integrity audit tool, not a full website crawler, SEO suite, screenshotter, browser renderer, vulnerability scanner, private link checker, backlink scraper, search-engine scraper, or uptime monitor.

It fetches only the provided public pages and a bounded set of discovered public HTTP/HTTPS links. It does not log in, use cookies, render JavaScript, bypass paywalls, submit forms, crawl private areas, or enrich private persons.

Not For

This Actor is not a full-site crawler, backlink index, rank tracker, vulnerability scanner, uptime monitor, screenshot tool, JavaScript renderer, or private authenticated link checker. It audits bounded public page links for downstream review.
