Content Decay Monitor Setup
Overview
Configure a recurring monitor that checks a list of pages or topics for organic performance changes. The monitor runs on a schedule (weekly/monthly) and alerts when performance drops below a threshold.
Inputs
- List of URLs or topics to monitor
- Monitoring frequency (weekly, biweekly, monthly)
- Alert threshold (e.g., 15% click decline, 20% impression drop)
- Optional: GSC property or GA4 property
Workflow
- Define the monitor scope: pages, topics, or both.
- Set baseline performance from current GSC/GA4 data.
- Configure the check frequency and alert threshold.
- Store the monitor configuration in a local file or agent config.
- On each check cycle: fetch current data, compare to baseline, flag pages below threshold.
- Route alerts to the user (with traffic-decay-detector for deeper analysis).
Output
Monitor configuration file and recurring check instructions for the agent runtime.
