Campaign launch monitoring
Don't let a broken landing page waste your ad spend
A landing page that quietly breaks keeps spending your budget while nothing converts. Sitewatch continuously checks the pages behind your campaigns and alerts you the moment forms, checkout flows or critical content stop working. You find out in minutes — not when the week's numbers come in short.
- Know before the click count climbs — not when conversions look strange on Friday
- We check what a visitor experiences, not just whether the server answered
- Add a campaign URL and you are live in two minutes. Nothing to install
Signup form stopped submitting
Plain-English summary
The form's script is missing, so visitors arriving from your ads can click submit and nothing happens. The page itself loads normally.
01What can go wrong
You have already paid for the click.
The ad is live and the budget is spending. Somewhere between the click and the conversion, one small thing quietly breaks — and nothing tells you.
- 01You are spending real money sending traffic to a single landing page.
- 02An edit or a deploy ships the page without its stylesheet, so it loads as raw text.
- 03The signup form's script goes missing, so clicking "submit" does nothing at all.
- 04The tracking script disappears with it, so the conversions you do get go uncounted.
- 05The page still loads. Your uptime tool still reports everything as healthy.
- Nobody notices until the budget is gone.
02Why traditional monitoring misses this
Your monitor said the page was healthy. It only checked one thing.
Traditional uptime monitoring stops the moment the server answers. We don't just check that your page is online — we check that people can actually use it.
Traditional uptime monitoring
Two steps. Everything after "it answers" is invisible.
Sitewatch
Only "healthy" once the whole page holds together.
03How Sitewatch catches it
One question, on every check.
Not "did the server respond?" — but the one that decides whether your ad spend converts: can a visitor actually use this page?
- ✓The layout loads
- ✓Buttons are still there
- ✓Form scripts load
- ✓Images appear
- ✓Fonts load
- ✓Tracking scripts load
- ✓Linked APIs respond
- ✓Redirects land on the right offer
04Typical failures we catch
The campaign breakage that quietly costs you conversions.
Landing page loads without its styling
The stylesheet fails and the page renders as raw text.
→Visitors bounce in seconds and the click is wasted
Signup form stopped submitting
The script the form depends on is missing or broken.
→Leads disappear and nobody notices
Tracking script disappeared
The analytics or ad-platform script is no longer being served.
→Conversions go uncounted and retargeting audiences stop filling
The call-to-action is hidden
A broken layout pushes the main button below or behind other content.
→Traffic arrives with nothing to click
Consent banner covering the page
A stalled consent script leaves the overlay stuck open.
→Visitors cannot reach the offer at all
Redirect sends traffic to the wrong page
A changed rule drops campaign traffic on the homepage or an old offer.
→You pay for the click and lose the message match
Hero and product images missing
A media or CDN change leaves the main images blank.
→The page looks abandoned and trust collapses
Countdown or offer timer fails
A launch timer errors and never renders.
→The urgency your creative promised is gone
Embedded video no longer loads
A video embed goes missing and leaves a blank block.
→The demo your ad promised never plays
05A real example
A broken form, caught before the spend adds up.
Paid click
A visitor lands on your campaign page from an ad.
Form breaks
Its script goes missing after an edit to the page.
Incident opened
Sitewatch confirms it is real and opens an incident.
Your team is alerted
Slack or email, with the exact file that is missing.
Fixed
Before the budget goes anywhere near a full day.
06What happens the moment we find it
Detection is not the outcome. Getting it fixed is.
Every incident arrives already diagnosed, so the first thing your team does is fix it.
We confirm it is real first
Every issue is re-checked before anyone is alerted, so a momentary blip never wakes you at 3am.
Explained in plain English
"The form's script is missing, so visitors can click submit and nothing happens." Not a status code — a sentence you can forward to whoever owns the page.
Sent where your team already works
Slack, email, webhook, PagerDuty, Opsgenie or SMS, with the exact page and the exact file that broke.
You can verify the fix
Run a check on demand the moment the fix ships and watch the incident close — before the next click lands.
07The cost of waiting
The same broken form, with and without monitoring.
The page never went down. That is exactly why it went unnoticed for so long.

09Everything we detect
The full checklist on every campaign page
The parts of the page
- Missing scripts — a form, tracking or widget file that is no longer being served
- Missing stylesheets — the page renders unstyled
- Missing images and fonts — blank heroes, fallback type
- Files served as the wrong kind of file, so the browser refuses them
- Script tags present in the page but pointing at a file that is gone
The page itself
- Hard outages, timeouts and server errors on the landing page
- Redirects that send visitors in circles
- Redirects that hand traffic to a domain you do not control
- A URL that returns something other than a web page
- Unexpected content changes after launch — a CMS edit, a cache purge, an overwrite
10vs. checking it yourself
Manual QA vs Sitewatch for campaign pages
| Scenario | Manual QA | Sitewatch |
|---|---|---|
| Broken form or tracking | Only if someone thinks to test the form today | Every file the page depends on, checked on every run |
| Redirects | Spot-check a few URLs before launch | Loops and wrong destinations caught on every check |
| Mid-campaign breakage | Open the page once before launch and hope | Checks every 5–30 minutes for the life of the campaign |
| Content changed after launch | No visibility once it is live | Unexpected changes flagged automatically |
| Who notices first | Usually the weekly report | You, within minutes, in Slack |
| Cost of being wrong | A day of paid clicks | Minutes |

Not a ping. Not a status code. The whole page — opened, loaded and verified — so a working ad always points at a working page.
11Questions
Campaign monitoring questions, answered
The landing page and everything a converting visitor touches: the form, the tracking and analytics scripts, images, fonts, styling and any redirect in the path. Sitewatch checks all of it on a schedule, not just whether the server answered.
Yes. It verifies that the scripts your form depends on are still being served. If one goes missing or is replaced with an error page, Sitewatch raises an incident — even though the page itself is "up" and your uptime tool stays green.
Not at runtime, and we would rather say so. Sitewatch checks that the tracking and analytics scripts your page references are present and still being served — which catches the common failure, where a script silently disappears. Sitewatch does not execute JavaScript, so it cannot confirm a pixel sent an event. For that, pair it with a browser-based tool like Google Tag Assistant.
Yes. Add each campaign URL on its own. Sitewatch treats them as critical pages and checks each one on its own schedule with its own alerts, so a problem on one offer does not hide behind another.
Yes. Point Sitewatch at a staging or pre-launch URL and run a check before you spend a single click. You can also trigger a check from a deploy hook, so every change to a live campaign page is verified the moment it ships.
Checks run every 30 minutes on the free plan, every 15 on Starter and every 5 on Pro, and you can run one on demand at any time. Issues are confirmed with a retry before you are alerted, so what reaches you is real.
It can. Sitewatch does the fundamental availability checks — outages, timeouts, server errors, certificate problems — and then keeps going to verify the page works. A campaign page that is "up" but broken still raises an incident.
No. Sitewatch focuses on whether the page works: the parts that load, the redirects, availability and content changes. It does not measure load time or Core Web Vitals. Pair it with PageSpeed Insights if speed is what you need.
