**Get told when an ad campaign's cost per result jumps.** Revnu watches your live campaigns and tells you when one's cost per booked call or sign-up jumps well above its normal, with its view on why.

_Watch · Ads and outbound_

## What it does

Costs drift up a little, then a lot. Revnu watches each campaign's cost per result against its own normal, trips when it jumps well above it, and tells you why it thinks it happened.

**Trips when:** Cost per result jumps well above the campaign's normal

**Checks:** Every few hours

## What Revnu does when it trips

1. Reads each campaign's spend and results.
2. Compares cost per result with the campaign's normal.
3. Trips on a real jump.
4. Says what changed: audience, creative, bids or tracking.

## What you get

**Cost per booked call jumped**

- Campaign and platform
- Likely reason

| What changed | Before | After |
| --- | --- | --- |
| Cost per booked call, 3 days | The campaign's normal | Well above it |

_The shape of a real alert. The numbers come from your own account and its usual pattern._

## FAQ

### Will it pause the campaign?

Only if you agree that when you set it up. Pausing follows your ads settings.

### Do I have to set anything up?

No. Ask in chat in your own words. Revnu writes the check, runs it once to make sure it works, and tells you what it's watching and how often.

### How often does a watch check?

Anywhere from every 5 minutes to once a week. Revnu picks a sensible interval, such as daily for a page that rarely changes, and you can change it any time.

### Will it message me when nothing happens?

No. A quiet watch messages no one. It trips once when something changes and won't fire again until things are back to normal.

### Can a watch read pages behind a login?

No. Watches read public pages and your own Revnu data: sends, replies, booked calls, ad spend, website tracking, Search Console and your leads.

### What does it cost?

Plans start at $99 a month, and Revnu starts on what you typed as soon as you sign up. Cancel any time in Settings.

### Does anything run before I sign up?

No. Nothing is checked or generated on this page. Revnu does the work inside your account, where it can read your website, keep what it finds and carry on from there.

### Where do I learn how Revnu works?

The docs at revnu.com/docs/get-started walk through your first day, and revnu.com/docs/what-revnu-can-do lists everything it can do.
