How to Monitor Broken Links: Scheduled Crawls or Manual Checks?
Compare scheduled crawl monitoring with manual broken link checks, see how automated crawl alerts and change comparison work, and pick the right mix for your site.
Broken links frustrate visitors and quietly erode trust in your site.
The question most operators face is not whether to monitor them, but how: run scheduled crawls that surface problems automatically, or check manually at intervals you choose.
This article compares both approaches, shows what a scheduled crawl setup looks like in practice, and helps you decide which mix fits your site and team.
Why broken links matter to revenue teams
A broken link is any link that points to a page that no longer exists, typically returning a 404 error.
Internal broken links send visitors and search engine crawlers into dead ends on your own site.
External broken links, where a page you cite has moved or been deleted, make your content look stale.
For revenue operations leaders, the cost is practical rather than abstract.
A prospect clicking from a campaign email to a retired pricing page creates friction exactly when you wanted momentum.
The same happens when a sales enablement deck links to a deprecated help article.
Monitoring exists to catch these before someone important does.
Manual checks: when they are enough
A manual check means someone opens a crawler, runs it against the site, and reviews the results.
Done well, this is a legitimate approach for small sites with infrequent changes.
The practical workflow is straightforward.
You crawl the site, filter for client error responses, and inspect each broken link to find the page that links to it.

Manual checks suit these situations:
- Small sites where a full crawl takes minutes and changes are rare.
- One-off audits before a launch, migration or redesign.
- Teams that want a human to judge every finding before anything is fixed.
The tradeoff is coverage.
Manual checks only protect you on the day someone remembers to run them.
Say a page is deleted shortly after your last audit: the links pointing to it stay broken until the next check.
If your publishing cadence is active, that gap is where problems accumulate.
Scheduled crawls: monitoring that runs without you
A scheduled crawl runs on a recurring basis and reports results automatically.
The value is not just detection but delivery: the findings arrive where your team already works, usually email, without anyone opening a tool.
Screaming Frog's SEO Spider supports this directly.
You can configure email notifications on crawl completion, either globally for every crawl or per scheduled task.
The notification email includes a summary and an issues table.
You can also attach specific exports, such as a broken links report.

Two features make scheduled crawls genuinely useful for monitoring rather than just repeated audits:
- Change comparison. Auto Compare compares the two most recent crawls in a project and highlights what changed, including changes in error counts and newly appearing issues, directly in the notification email. This turns a raw crawl into a signal: you see what is new, not everything that was already there.
- Targeted attachments. Selecting the broken links export in the scheduled task means developers or content owners receive exactly the list they need to fix, on the schedule you set.
One setup detail matters: Auto Compare works on the two most recent crawls within a project folder.
Each domain needs its own project to avoid comparing unrelated sites.
What a scheduled crawl actually catches
A crawl finds links that return error responses.
That covers most broken link problems, but not all of them, and knowing the boundaries helps you set expectations.
Standard crawls detect 404 responses.
They also surface redirect chains, which matter because a link may appear to work while passing through several hops before landing on an error page.
Screaming Frog's tutorial notes that the reported source URL can itself be a redirect.

Some breakage does not produce a 404 at all.
Jump links, which point to a named anchor within a page, fail silently when the target section is renamed or removed, because the page itself still loads normally.
These need separate handling.
There is also a structural blind spot worth understanding: a crawler can only find links it can reach.
If navigation or markup prevents a crawler from following certain links, the crawl will not see them either.
Our guide on internal links crawlers cannot follow covers how to check for that before trusting any crawl report as complete.
Choosing the right mix for your site
The honest answer is that most teams benefit from both, weighted by how often their site changes and who fixes what.
Use scheduled crawls as your baseline when any of these apply:
- Content is published or updated regularly, so new broken links can appear at any time.
- Multiple people own different sections, and findings need routing to the right owner automatically.
- You manage several sites or client properties and cannot audit each one by hand.
- You want trend visibility, such as whether error counts are rising after a migration.
Lean on manual checks when the site is small and stable, or when you need judgment-heavy review.
That includes deciding whether a broken external citation should be updated, replaced or removed.
A scheduled crawl can flag that a link is broken; only a person can decide the best replacement.
A common pattern is to run scheduled crawls for detection and hold a short manual review session for triage.
The crawl does the looking; the team does the deciding.
This mirrors the broader principle that recurring monitoring is an infrastructure decision, not a tooling decision.
Our article on automation infrastructure and manual handoffs explains why the handoff design, not the tool choice, determines whether monitoring actually leads to fixes.
Routing alerts to the right owner
Monitoring fails quietly when alerts go to a shared inbox nobody owns.
Before scheduling anything, decide who acts on each type of finding.
- Internal broken links usually belong to whoever owns the linking page, often content or web teams.
- External broken links in editorial content belong to the content owner; in documentation or sales material, they may belong to enablement.
- Redirect chains ending in 404s typically need someone with access to redirect rules or server configuration.
Export attachments make this routing practical.

Also decide what deserves attention.
A single broken external citation is a low-priority content fix.
A sudden appearance of many internal 404s after a page deletion is urgent, because every affected page now dead-ends.
Change comparison in scheduled crawls is what makes this distinction visible without reading full reports.
Practical setup checklist
If you are setting up scheduled monitoring, work through these steps:
- Choose a crawler that supports scheduling and email notifications, and connect an email account to send from.
- Create a separate project per domain so crawl comparisons stay meaningful.
- Enable change comparison so notification emails highlight new and changed issues rather than repeating the full list.
- Select the broken links export as an attachment so the fix list arrives with the alert.
- Set a crawl frequency that matches your publishing cadence; a site that changes weekly does not need the same interval as one that changes quarterly.
- Agree in advance who handles internal links, external links and redirect fixes, so alerts have an owner from day one.
For teams coordinating marketing and sales systems, the same pattern applies beyond links: detection should be automated, and human effort reserved for decisions.
Our piece on manual handoffs in content operations explains why unowned handoffs, not missing tools, let broken links persist.
The bottom line
Manual checks are fine for small, stable sites and for judgment calls about what to fix.
Scheduled crawls with change comparison and targeted email attachments are the better baseline for sites that change regularly or have multiple owners.
They surface new problems and route them without depending on someone remembering to look.
Most teams do best with scheduled monitoring for detection and a lightweight manual review for triage and repair decisions.
Monitor automatically, decide manually: let scheduled crawls find the breakage, and keep people in charge of choosing the fixes.
