Monitor
Broken link monitor that emails a single sentence, not a 12-page PDF.
Most small sites have a handful of outbound links that quietly rot to 404. SiteGuardian re-probes them weekly and emails you the moment one breaks. One short sentence, the link, the new status.
- Weekly re-probe of every URL on your outbound-link list.
- One short email the second a link returns 404 or fails.
- Recovery email the day the link answers again.
- No crawler to install on your server. SiteGuardian probes from the outside.
- Free on every plan. Starter, Pro, and Lifetime all ship it.
How it works
Setup, in three beats.
Step 01
Paste the URL list you maintain yourself
SiteGuardian pings the URLs you give it. If you want it to find your outbound links automatically, give it your home page and SiteGuardian will read the visible links from there. Either way the watch starts inside the next minute.
Step 02
Let the weekly cadence run
SiteGuardian probes each link on a weekly cadence and emails you when one returns 404 or 5xx. The alert is one sentence: the link, the new status, and a one-line suggestion to fix or remove.
Step 03
Patch as you read each one
Most small sites accumulate 5 to 20 broken links over a year. The boring safeguard is the weekly cadence: you fix them as you find them, and your site stays clean without anyone having to run a quarterly audit.
