Competitor SERP Monitor
Overview
Monitor a set of competitor domains for changes in their organic search presence: new pages appearing in top positions, ranking shifts, SERP feature acquisition or loss, and content strategy changes.
Inputs
- List of competitor domains to monitor
- Optional: shared keyword list or topic cluster
- Check frequency (default: weekly)
Workflow
- Define the competitor set and shared keywords or topics.
- For each keyword, fetch the current SERP and record:
- Which competitor domains appear and at what rank
- SERP features (featured snippets, PAAs, video, images)
- New URLs from competitors (not seen in previous check)
- Compare against the prior SERP snapshot.
- Flag changes: new competitor entries, rank improvements, SERP feature gains.
- Analyze new competitor content for angle, format, depth, and entities covered.
- Surface threats (competitor gaining on your positions) and opportunities (competitor losing ground).
Output
Competitor movement report with new pages, rank changes, SERP feature shifts, and content analysis.
