Real-browser monitoring
Checks run through actual browser execution rather than relying solely on HTTP uptime checks.
SpotCheck.ad
Your ads go missing. So does your revenue.
SpotCheck.ad checks your advertising placements in a real browser, detects suspicious failures, and captures the evidence you need to investigate—before silent problems go unnoticed.
SpotCheck.ad isn't just ad monitoring. It's protection against silent revenue loss.
The silent failure
Your website can be working perfectly while your ads aren't.
A page can load normally even when an advertising placement fails. Broken integrations, layout changes, blocked resources, or missing elements can go unnoticed until an advertiser complains—or someone happens to check the page by hand.
How it works
From page to placement evidence in four steps.
Built so a nontechnical publisher can understand what is being monitored and why a check matters.
- 01
Add your website
Register the website and pages that contain advertising placements you care about.
- 02
Identify your placements
Select the placements you want to monitor and establish a confirmed baseline of expected conditions.
- 03
Check in a real browser
SpotCheck uses SiteLens to load the page, inspect configured placement signals, progressively scroll where enabled, and capture evidence.
- 04
Investigate problems
Review check results, repeated verification, screenshots, and incident history when something looks wrong.
Capabilities
What SpotCheck watches for—and what it shows you.
Focused advertising placement monitoring with browser evidence, not a generic uptime dashboard.
Placement baselines
Confirm expected placement conditions once, then compare later checks against that baseline.
Progressive scrolling
Where configured and supported, SpotCheck can check placements that sit below the fold.
Evidence capture
Browser screenshots and execution evidence help you investigate what a check observed.
Conservative failure verification
Suspicious results are not automatically treated as confirmed incidents. SpotCheck uses repeat verification to reduce noise—without promising perfect accuracy.
Incident history
Track observed problems and their status over time so recurring issues are easier to spot.
Alerts
Configure notification preferences for monitored placements as your workspace is ready. Delivery channels should be verified in your environment before relying on them operationally.
Evidence, not guesswork
Don't just hear that an ad failed. See what happened.
Browser evidence and check history help publishers investigate advertising problems—with screenshots, placement inspection results, and a timeline of what SpotCheck observed.

Who it's for
Built for publishers who depend on advertising.
When advertising revenue matters, silent placement failures are an operational risk—not just a technical detail.

- Digital magazines
- News websites
- Content networks
- Teams managing multiple advertising placements
