Outbound link checker Beta

Check your external links for dead sources and citations that no longer hold

A broken-link checker tells you a page returns 404. CiteRanger also tells you when a source still loads but no longer supports the claim you attached to it, which is the failure nobody catches.

Why link checkers miss most citation problems

Status 200 is not a valid citation

A study page that was rewritten, a product page whose price changed, a report replaced by a newer edition: all return 200. All no longer say what your page says they say.

Links rot faster than anyone budgets for

Pew Research found that 38% of web pages that existed in 2013 were gone by 2023. Every outbound link on your site is a dependency on someone else's maintenance.

Redirects hide the loss

A dead study URL that redirects to a publisher's homepage passes every checker and supports nothing. Readers who click it lose trust; raters who check it lower the page.

How the outbound link check works

Every external link is checked on two levels: does it resolve, and does the target still contain the claim your page cites.

  1. 1

    Scan the page or the site

    Paste a URL or import your sitemap. CiteRanger extracts every outbound link together with the claim it is attached to in your text.

  2. 2

    Two checks per link

    First the technical one: does the link resolve, and where does it end up after redirects. Then the one that matters: does the target page still contain the statement, number or fact your page attributes to it.

  3. 3

    Fix with a replacement in hand

    Dead and drifted sources are listed per page with the original claim. Where a current source confirms the claim, CiteRanger shows it, so the fix is a link swap instead of a research task. Export the list or set an alert for pages whose sources keep changing.

What CiteRanger checks in every article

The scan extracts every factual claim from the page and verifies it against current sources. Six claim types cover most of what goes stale.

Statistics and numbers

Market sizes, growth rates, survey results, percentages

Prices and plans

Product prices, subscription tiers, fees, cost comparisons

Company facts

Employee counts, headquarters, leadership, acquisitions

Dates and timelines

Product launches, deadlines, historical events, schedules

Product details

Specifications, features, integrations, limitations

Legal and regulatory

Regulations, requirements, certifications, standards

More than a link status report

Claim-to-source matching

Each link is judged against the specific statement it supports, not as an isolated URL.

Judged at the final destination

Links are followed through redirects and checked where they actually land, so a source that now points at a homepage or an unrelated page counts as lost.

Replacement sources

When a current source confirms the claim, it is shown next to the dead one.

Site-wide, on a schedule

Run it across the archive via sitemap and put link-heavy pages on scheduled scans with email alerts.

Frequently asked questions

Is this a broken link checker?
It includes one, but that is the smaller part. Broken-link checkers test whether a URL returns an error. CiteRanger also tests whether the page behind a working link still contains the claim you cite. Most bad citations on the web are of the second kind.
What is a drifted source?
A page that still exists but has changed so that it no longer supports your claim: a statistic updated to a new figure, a price changed, a documentation page rewritten, a study replaced by a newer edition at the same URL. Link checkers cannot see this; CiteRanger compares the claim to the current page content.
Does it check internal links?
The focus is outbound links, because those are the ones you do not control. Internal link problems show up in any crawler; drifted external citations do not.
Why do outbound links matter for SEO?
Google's guidance asks whether content has easily verified factual errors and its raters assess trust partly through sourcing. A citation that no longer holds is a factual error with a link on it. The one controlled experiment on outbound links (Reboot Online, 2016 and 2020) found a positive effect from linking to authoritative sources.
How often should I check external links?
Once across the whole archive, then on a schedule for the pages that carry the most links and traffic. Quarterly is a reasonable default for time-sensitive topics; scheduled scans with alerts handle the pages you cannot re-read by hand.
What does it cost?
One credit per page scanned, and the outbound link check is part of every scan. The free plan includes 15 credits with no credit card.
