Monitoring

Monitoring is Cosma watching the things that quietly break — conversion tracking that drops out, and budget bleeding into terms that never convert. Set it up once per client and it runs in the background.

Conversion monitoring

Conversion data is the foundation of every ROAS and CPA number you report. When a pixel breaks or a conversion action stops firing, your reporting silently goes wrong. Conversion monitoring catches that.

Where to find it

Open Client Settings → Monitoring. You'll see any existing rules and a button to add a new one. Rules are per-client.

Client Settings → Monitoring, showing Custom Alert Rules and Conversion Monitor Rules sections — Client Settings → Monitoring

Create a conversion monitor rule

Click New rule and pick the ad account to monitor.

Choose the conversion action(s) to watch — search and select the specific conversions that matter (e.g. Purchase, Lead). Use the search box to filter long lists.

Set the volume-drop threshold. By default Cosma alerts when conversions fall more than 30% versus the recent baseline, with a minimum of 3 conversions so tiny accounts don't trigger false alarms. Tune both to your account's size.

Conversion monitor rule modal: triggers, stale-data window, and 30% / min-3 volume-drop threshold — Conversion-drop rule — triggers, stale-data window, and drop threshold

Cosma compares against a rolling baseline, so a normal weekend dip won't fire — only a real, sustained drop will.

What you'll get

When a monitored conversion drops past your threshold, Cosma raises a flag on the brief and (if you've set a channel) sends an alert. The daily conversion digest summarizes any volume drops across the account.

Wasted-spend audit

The wasted-spend audit surfaces budget going to search terms, placements, and audiences that spend but never convert — the classic leak every account accumulates.

It runs automatically across your connected platforms and refreshes regularly. You'll find the wasted-spend widget on your Dashboard and in the Save Money pillar. While it's building you'll see a spinner; once ready, a “Last updated” badge shows how fresh it is.

Cosma advises, you decide. Monitoring surfaces the leak and links you to the exact place to fix it — you make the change in the ad platform.

Recommended setup

Add a conversion monitor for each client's primary conversion action on every connected platform.
Pair it with a delivery channel so drops reach Slack or email immediately.
Review the wasted-spend list weekly — it's where the fastest savings usually are.

That completes the core setup. Head back to the docs home any time, or jump to the Morning Brief guide.
