How to reduce false positives?
If you get false alarms, try to change the screenshot-settings of your job:
Increase Trigger: Avoid using “any” change if small areas of the page changes but are not relevant for what you want to track.
Adjust Selection: Avoid selecting areas that change frequently like ads, carrousels, twitter counts etc. You can select a custom crop area using Visual mode or an element using Element mode. You can monitor specific blocks of text by following the steps outline in this article.
Adjust Compare Type: Use Text Mode instead of Visual if you are only concerned about text changes. Element mode is ideal for when the page layout frequently changes and the area that is monitored shifts vertically.
Use the Block action: This blocks elements from being uploaded before taking a snapshot. Use this to remove pop-ups, banners or ads. You can learn more about this feature here.
