# Ignore zones for visual monitoring

> Mask ads, cookie banners, or rotating widgets so visual monitoring only alerts on real changes.

## Quick answer

 Draw a box over any part of the screenshot Lemwatch should skip when comparing. Ads, cookie banners, live chat widgets, and rotating carousels are the top candidates.

## What it does

- Excludes the boxed region from both pixel diff and text diff

- Applies the mask to every future capture on that page

- Shows the mask overlay on all historical screenshots so you can audit it

## Where to find it in Lemwatch

 **Visual Monitoring → [page] → Ignore zones** → click **Draw zone**.

## How to add one

- Open the page in Visual Monitoring.

- Click Ignore zones → Draw zone .

- Drag on the screenshot to cover the noisy region.

- Name it (e.g. "Cookie banner") so you remember why it's masked.

- Click Save . The mask applies on the next capture.

## FAQ

### How many ignore zones can I create per page?

 Up to 10. If you need more, consider watching a [CSS selector](https://lemwatch.com/help/css-selector-monitoring) instead.

### Can I ignore based on element rather than pixel box?

 Yes — CSS selector monitoring is the element-based version.
