Monitor one section of a webpage for changes
Receive scheduled email alerts when selected text or HTML on a public webpage changes.
Stay on top of changes without checking manually
MonitorCat returns to the section you selected on each scheduled check and compares its text, HTML or both with the last successfully found version.
How it works in MonitorCat
Add the public page
Enter the page URL and choose Content Change as the monitor type.
Select the relevant element
Highlight the section you want to follow rather than monitoring the entire page.
Choose text, HTML or both
Text detects wording changes. HTML can also detect structural or markup changes inside the selection.
Receive a scheduled-change email
When a check finds a difference from the previous comparable result, MonitorCat records it and can email you.
Everything you need to review a change
Select one page section
Changes to navigation, adverts, timestamps and recommendations are ignored when they sit outside your selection.
Text and HTML detection
Watch readable text, underlying HTML or both, depending on the kind of change you want to catch.
Recent check history
See whether each check changed, stayed the same, failed or could not find the selected element.
Scope and limitations
MonitorCat needs to load the public page and find the selected element again. Page redesigns, consent screens, personalisation or dynamic rendering can make an element unavailable. A missing selection is reported as not found, not automatically treated as a genuine content change.
Common questions
Should I monitor text or HTML?
Use text to follow wording changes. Add HTML when you also want to detect markup or structural changes inside the selected element.
