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.
