Content Decay Detection

Find declining old content that needs refresh

What is Content Decay

Content "rots" over time:

Information becomes outdated (2023 data is stale in 2026)
Competitors publish better content
Search intent changes
Google algorithm updates

Result: Rankings drop → Traffic drops → Revenue drops

Detection Criteria

Metric	Threshold	Description
Publication Date	>6 months	New content doesn't count as decay
Traffic Change	Down >20%	Compared to 3 months ago
Ranking Change	Down >5 positions	Primary keyword
CTR Change	Down >15%	Title may need updating

Trigger Refresh: Meeting any 2 criteria = needs refresh

Workflow

Method A: With GSC Data

User provides GSC export (CSV)
↓
Analyze each URL:
- Impression trends
- Click trends
- Average position trends
- CTR trends
↓
Identify decaying content
↓
Output refresh priority list

Method B: Without GSC Data

User provides URL list
↓
Check each page:
- Publication date / Last updated date
- Content timeliness signals (years, "latest", etc.)
- Competitor SERP analysis (your content vs Top 10)
↓
Identify potentially decaying content
↓
Output recommendation list
