If a check ran after the change but did not capture it, check the selected area, page loading and actions, alert criteria, and access restrictions. If the dashboard shows a detected change but no email arrived, troubleshoot notification delivery separately.
1. Confirm a check ran after the page changed
Open the monitor’s Check History in the dashboard and compare its timestamps with when the site changed. A scheduled monitor checks and compares the page; it does not alert at the instant the site updates. A long interval can therefore make an alert arrive well after the change. Visualping’s Help Center recommends checking history first: Navigating Alerts.
- If there is no check after the change, confirm the monitor is active and review its schedule.
- If the monitor is local, make sure Chrome was open and the device was available for the scheduled check. Cloud monitors run on Visualping’s servers and do not rely on your computer being on.
- If a check did run, use the remaining steps to determine whether it saw the relevant content and whether the alert criteria accepted it.
Visualping explains the timing plainly in its setup guidance: a check must happen before the service can detect a change and alert you. See Navigating Alerts and How to create a basic monitoring job.
2. Check whether Visualping is monitoring the right content
Whole page or selected element
Review the monitor preview and confirm the capture covers the changed content. A monitor aimed at one element will not alert on a change elsewhere on the page. If the selection tool did not identify the intended area, Visualping’s setup guidance suggests using a direct XPath, class, or selector. Check whether the element is inside an iframe, too: content in an iframe may not be covered by the selection you made. See How to create a basic monitoring job.

Content that appears after loading or interaction
Some pages reveal content only after scrolling, opening a dropdown, dismissing a popup, or completing another page action. Check the preview and any warnings for failed pre-actions. Use the available action or scroll settings when needed, then confirm the target content appears in the monitor’s preview. Visualping’s setup guide also recommends checking page limitations when expected content is missing: How to create a basic monitoring job.
3. Review the alert criteria and focus area
A check can run successfully without producing an alert if the selected area or detection criteria do not treat the observed difference as a reportable change. If you need to catch any difference, Visualping’s setup guide offers an Any changes choice; the trade-off is that it can create more false alerts. For fewer irrelevant alerts, refine the prompt and focus area, and avoid volatile content such as ads or counters. See How to create a basic monitoring job.

4. Investigate access, security checks, and location
A page may look different to the monitor because it presents a login gate, bot check, security challenge, or location-specific version instead of the expected content. Inspect the preview for those signs. Visualping suggests trying Basic Proxy or a checking location in the website’s country for bot detection, security checks, or geoblocking, and reviewing the Block ads and cookies advanced setting. These are troubleshooting options, not a guarantee that a particular site will allow monitoring. See How to create a basic monitoring job.
5. Separate change detection from email delivery
If the dashboard shows a detected change but you did not receive an email, the monitor may have detected the change correctly while notification delivery failed or was disabled. Check the monitor’s Notifications tab and verify email is enabled. Then check whether the workspace is muted, whether other workspace users received the alert, and whether your spam or junk filter caught it. Visualping says email is enabled by default, but confirm the monitor’s current setting rather than assuming it is on. Its notification overview also lists other channels—including CC email, SMS, webhook, n8n, Telegram, API, MCP, Slack, Google Sheets, Microsoft Teams, Discord, and RSS—with availability depending on channel and plan. See Navigating Alerts and Visualping notifications.

If the monitor history confirms detection and the notification settings look right, Visualping says an alert can still be suppressed by system configuration or fail the job’s alert settings. Contact support with the page URL or job name, what changed, and when it happened.
6. Check website-error alerts separately
If the page failed to load or the crawler was blocked, that is different from a successful check that found no relevant content change. Visualping documents a separate Alert on Website Error setting. Its Help Center says that monitors without a prior error-alert configuration now alert after consecutive failures based on the check interval: its examples are five failures for a five-minute schedule and three for a daily schedule. Explicitly turning the option off keeps error alerts off. Because defaults and behavior can change, inspect the setting on the monitor rather than relying on an old configuration or assuming an error alert will be sent. See Website error alerts.

7. Send support enough detail to investigate
If the cause remains unclear, give Visualping support the evidence needed to distinguish a missed check, a capture problem, and a notification issue:
- The monitored page URL or job name.
- When the page changed, or when the check failed.
- What you tried, including any settings or actions you changed.
- The relevant error message or preview warning.
These details are specifically requested in Visualping’s support guidance: Navigating Alerts and How to create a basic monitoring job.
