Landing Page Monitoring: How to Catch Broken Forms and Dead CTAs

Why broken landing pages drain budget silently

Landing pages are where paid traffic lands, which makes a silent break unusually expensive. If a form stops submitting or a 'Start Free Trial' button loses its link after a deploy or an A/B-test change, the page still returns a healthy status and looks normal — but the leads and signups simply stop, while your ad spend keeps flowing.

These breaks are easy to miss precisely because the page looks fine. A marketer glancing at the page sees the headline and the form; they do not necessarily test that the form actually submits or that the button still points somewhere. The failure hides in the interaction, not the appearance.

Because conversions are often a small percentage of visits, a broken form can run for days before the drop is obvious in analytics. By then you have paid for a lot of traffic that had no way to convert.

How to monitor a landing page effectively

Monitoring a landing page means testing the conversion action itself, on a schedule, the way a real visitor would. NorthDuty lets you describe the journey in plain text — open the page, fill the form, click submit, or click the primary CTA — and runs it on a schedule, confirming the whole path still works rather than just that the page loaded.

Alongside the journey, NorthDuty's health check renders the page and catches JavaScript errors and broken resources that can disable a form or button, and a journey that clicks the CTA fails at that step, with a screenshot, if a layout change hides it.

When something breaks, you are alerted immediately with the reason, so you can fix it before the next wave of paid traffic arrives. For a page tied directly to ad spend, that speed is the difference between a minor blip and a wasted campaign.

The cost is the ad spend, not the downtime

Do the arithmetic for your own campaign. At $2 a click and 200 clicks a day, a form that stops submitting on Friday afternoon has spent about $1,200 by Monday morning — with no downtime, no alert, and a page that looks entirely normal to anyone who opens it.

Analytics will not rescue you either, at least not quickly. Conversions are a small percentage of sessions, so a complete stop looks like an ordinary bad day for the first day or two. By the time the drop is unambiguous in a weekly chart, the money is gone.

The fix is unglamorous: run the conversion action itself, on a schedule, on every page that paid traffic lands on. A form fill and submit every fifteen minutes turns a weekend of wasted spend into a fifteen-minute gap.

Conclusion

A landing page that loads but cannot convert is worse than one that is down, because you keep paying for traffic with no way to capture it. The failure hides in the form and the button, not the page load.

NorthDuty monitors the conversion path itself — journeys, JavaScript errors, and rendered page health — so a broken form or dead CTA is caught and flagged before it quietly drains your campaign.
