Why this helps
Visual checks get skipped when page URLs and review notes are scattered across sheets and browser tabs.
- Create a visual review artifact when a tracked URL changes.
- Keep page review tied to the sheet range that triggered it.
- Use screenshots to spot visible layout or content differences.
Setup
Build it in a few focused steps.
- 1Connect Google Sheets and Anchor browser once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3In one instruction, ask Notis to screenshot the webpage URL in the changed range and summarize what is visible.
- 4Choose Cell Range Values Changed as the trigger and select where run reports should go.
- 5Test with one real URL change in the monitored range.
Questions about this workflow
Does this compare the new screenshot with an earlier one?
The screenshot action captures a page image. A comparison needs an earlier screenshot or baseline that you provide or make available.
What should the monitored range contain?
Put the webpage URL you want captured in the monitored cell or range.
