Diving deeper: using advanced options
Use AlertChecker's advanced options to set notification criteria, checking priority etc.
By default, AlertChecker watches for a statement to become true, requires two consecutive matching results, and disables the alert after notifying you. Advanced options let you change the behaviour when your alert needs a different balance of speed, certainty, or repeat notifications.
Choose how you are notified
Under "More options", choose email, push notifications, or both. Email is useful when you want a record of the alert and its result; push notifications are useful when you want to see a result on a supported device right away. Push notifications need to be enabled in your browser after creating the alert.
Check priority controls how much checking capacity an alert receives. Leave it at medium for ordinary alerts. Choose high when a time-sensitive outcome matters more, or low when it does not. Higher priority means checks are scheduled relatively more often, although actual frequency still depends on demand and the complexity of the alert.
Choose the result that matters
The "Notify when" setting can trigger on true, false, or both. True is the normal setting for a typical “tell me when it is available” alert. False could be used if you'd prefer not to negate a statement and instead get notified when it isn't true. Choose both when a change in either direction is of interest.
Keep "Only when answer changes" switched on when you care about transitions, such as a price crossing a threshold or stock appearing. Switch it off only when repeated confirmations are useful. In that mode, AlertChecker keeps the alert active and limits notifications to once a day, rather than sending a notification for every matching check.
Balance speed against confidence
"Confidence" controls how many consecutive matching results are needed before notifying you: "low" needs one, "medium" needs two, and "high" needs three. Use "low" when speed matters and you can verify the result yourself; use "high" when a false alert would be especially disruptive. "Medium" is a sensible default for most alerts.
For change-only alerts, "Notify at most" controls whether you can be notified whenever the result changes or no more than once a day. "Disable after notifying" is useful for one-off outcomes, such as an item returning to stock. Leave it unticked for a recurring alert that should continue monitoring after each notification.
Start simple, then adjust
The defaults are usually a good starting point. If you receive alerts too soon, too late, too often or not often enough, find the alert in the "My alerts" page and adjust the option that addresses that specific problem.
