Add a page to visual monitoring, pick a schedule, and get pixel-diff alerts when it changes.
Quick answer
Open the site, go to Visual Monitoring → Add page, paste the URL, pick a check frequency, and save. Lemwatch captures a baseline screenshot and starts comparing every run.
What it does
Captures full-page screenshots on a schedule (hourly, daily, weekly)
Compares each new capture to the last baseline using pixel + text diff
Flags changes above your sensitivity threshold as incidents
Stores every screenshot for 90 days so you can scrub the timeline
Where to find it in Lemwatch
Site details → Visual Monitoring tab → Add page. Full path: Sites → [your site] → Visual Monitoring.
How to set it up
Open the site and click Visual Monitoring.
Click Add page and paste the exact URL you want watched.
Choose a check frequency — hourly for high-change pages, daily for marketing pages.
(Optional) Add a CSS selector to watch a single element instead of the full page.
Click Save. The first run is your baseline; no alert fires.
