My page has changed but I didn't receive a notification
There are some cases where we can't detect changes:
- Where the change is in an iframe
- Where the change is to an image - we just track text
- Where the only change is a deletion - we only track new text
We'll also ignore certain types of changes if you have the "Ignore small changes" option set. More on that here: What does the "Ignore small changes" option mean when creating a track?
Tracking changes on webpages is a complex business - and there will always be situations where we get it wrong. Bear in mind we offer a "best effort" service and can provide no guarantee that we'll alert you to a particular change.
