Landing page monitoring Know when a client page breaks.

Why Google Ads landing pages break

A landing page is not done when it goes live. It keeps changing. Most of those changes are made by people who are not thinking about your ads.

Here is how a page that worked last month stops working this month:

• Someone edits it. The client adds a new photo, a banner, or a second form. The new hero image is huge. The page slows down.
• A plugin updates. A form or page builder plugin updates on its own. The thank you page changes, and the conversion stops firing.
• A new script goes in. A chat tool, review widget, or call tracking script gets added. Load time jumps.
• The tracking gets removed. A page is copied or rebuilt, and the Google Ads tag or Tag Manager does not come with it.
• A redirect changes. The domain moves or a URL changes, and the ad now lands somewhere new.

One scan catches what is wrong today. It cannot catch what breaks next Tuesday. That is the job of monitoring.

What to watch on every ad page

For each page your ads point to, you want to know a few things each week.

• Did the score drop? A drop on the 0 to 100 score is the first sign something changed.
• Did it get slower? Watch the performance score and Core Web Vitals, especially Largest Contentful Paint on mobile.
• Is the conversion tag still there and loading? A missing or broken tag means leads come in but Google Ads never hears about them.
• Is the conversion ID real? A placeholder ID from a copied page counts nothing.
• Is the conversion linker on? Google says to put a conversion linker on any page where people land after an ad click, so conversions can be tied back to the click.
• Does the page still load at all? Google's destination rules say ads can be disapproved when the destination does not work or returns an error to Google's ad crawler.

That last one matters. A broken page does not just waste clicks. Under Google's destination requirements, a page that does not work, can't be crawled, or redirects to a different domain can get the ad disapproved.

How ClickMend landing page monitoring works

ClickMend checks the page a Google Ad sends people to, called the final URL. On paid plans, it checks each monitored page every week and sends an alert when a page gets worse.

Each check runs the same tests as a full landing page audit:

• A score from 0 to 100, built from Google PageSpeed Insights: performance (40%), Core Web Vitals (25%), SEO basics (20%), best practices (10%), and accessibility (5%).
• Core Web Vitals from real Chrome users when Google has that data, and lab data when it does not.
• Tracking checks: conversion tag present, tag loaded, placeholder conversion ID, Tag Manager missing, conversion linker off.
• The slow parts named, such as unused JavaScript.

Because the same tests run each week, you can compare. You see what changed, not just where the page stands.

Plans differ by how many client workspaces and pages you need. One workspace per client keeps each client's pages apart.

A simple weekly routine for agencies

If you run Google Ads for ten clients, you might have thirty or more landing pages. Nobody opens all of them every week by hand. Here is a routine that works.

1. Add every final URL. Pull them from each client's active ads. Put each client in their own workspace.
2. Set a baseline. The first check shows where each page stands today.
3. Read the alerts, not every report. Only open a page when it gets worse.
4. Fix tracking first. A missing tag hurts more than a slow image, because it cuts off the data your bidding runs on.
5. Ask the client what changed. Most drops line up with an edit, an update, or a new tool. Knowing the date makes the fix fast.
6. Check again after the fix. Make sure the score came back and the tag loads.

This also helps the client talk. When a client asks why leads slowed down, you can show the date their page changed and what it did to the score.

What monitoring catches

Real results from contractor ad pages. Names are left out on purpose.

The handyman case shows the cost of not looking. The ads ran, but Google Ads was never told about a single form conversion. Nobody looked at the page, so nobody knew.

Start with one free scan of your most important ad page at the health check. If it finds problems, fix them, then put the page on weekly monitoring so you hear about the next one before your client does. For speed problems, see the landing page speed test guide. For tracking, see Google Ads conversion tracking not working.
