What are Custom Alerts in Google Analytics
Custom alerts are bespoke notifications set up in Google Analytics to help you monitor important changes to your data, so you don’t have to perform daily manual checks. Custom alerts are set up at the view level of your Google Analytics account. Once an alert is set up, you will recieve an email when the alert conditions trigger. A custom alert email will have the following:
- The date of the alert
- The analytics property number
- The property view the alert is for
- The name of the alert. Example: sessions loss alert

Which Google Analytics Custom Alerts Should I Set?
There are no hard rules on what you can set custom alerts on, basically, you can set alerts on whatever you want. We advise clients to set alerts on at least the following: metrics that have an immediate impact on KPI’s, promotion campaign and site use I.e. Increase in 404s or 404 pages viewed.

- Session loss
- Increase in 404s
- Increase in 404 pages viewed
- Decrease in traffic YoY
- Increase in bounce rate
- Decrease in page views
- Slow loading page
