Content Decay Monitor

Pro Feature

Track and prevent content performance decline using Google Search Console data

Overview

The Content Decay Monitor uses real Google Search Console data to identify content losing search traffic over time. It provides two main views: a Dashboard tab that runs decay analysis comparing Search Console periods and displays decline metrics (Traffic Change, Impressions, CTR Change, Position, Severity), and an Analytics tab with chart visualisations of the same data.

Understanding Severity Levels

The Content Decay Monitor categorises declining content into three severity buckets based on performance drop:

Mild
20-30% decline
Monitor situation
No immediate action
Moderate
30-50% decline
Schedule content review
Within 2 weeks
Severe
>50% decline
Urgent refresh needed
Immediate
How severity is calculated: The shipped dashboard uses performance-based severity labels (Severe, Moderate, Mild) tied to decline thresholds, not content age. The internal severity score (1–5) is calculated from the percentage traffic change between the two comparison periods.

Frequently Asked Questions

How often should I run decay analysis?

For most sites, weekly analysis is optimal. High-traffic sites may benefit from daily checks, while smaller sites can use bi-weekly or monthly schedules.

What causes content decay?

Common causes include algorithm updates, increased competition, outdated information, seasonal changes, technical issues, and shifts in user intent.

How long before seeing recovery?

Recovery timelines vary: Minor updates (2-4 weeks), Major refreshes (4-8 weeks), Complete rewrites (8-12 weeks). Results depend on crawl frequency and competition.

What's the minimum traffic for accurate detection?

For GSC-based decay detection, pages need at least 10 clicks in the comparison period. The Dashboard tab uses content age as a proxy for decay, which works for all content regardless of traffic.

Is Google Search Console data required?

GSC is recommended for accurate traffic-based decay detection. However, the Dashboard tab can list posts by modification date even without GSC connected, but decay scoring requires GSC data.
