Detect content decay from Google Search Console exports by comparing current and previous page performance, flagging quarter-over-quarter traffic drops, dropped pages, and refresh, consolidate, prune, or query-shift actions. Use when the user says "/blog decay", "content decay", "traffic drop", "QoQ decline", "GSC decay", or "refresh declining posts".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Blog Decay

Use `/blog decay` to find pages whose Google Search Console performance has
declined quarter-over-quarter. The command compares a current-period export
against a previous-period export, flags pages with a 20% or larger decline by
default, and recommends the next content action.

## Default Offline Workflow

Run the local analyzer against two GSC page exports:

```bash
python3 scripts/content_decay.py current.json previous.json
```

Useful options:

```bash
python3 scripts/content_decay.py current.json previous.json --threshold 0.30
python3 scripts/content_decay.py current.json previous.json --metric impressions
python3 scripts/content_decay.py current.json previous.json --format markdown --output decay-report.md
```

The script accepts JSON lists of page rows with `page` or `url`, `clicks`, and
`impressions`. It also accepts the object shape returned by `blog-google` when
the rows are under a top-level `rows` key.

## Optional Live GSC Export

For live data, use `/blog google gsc` or the underlying `blog-google` command
to create each period export, then run the offline analyzer:

```bash

How to install

The exact contents, by fingerprint

mdr add agricidaniel/claude-blog/blog-decay@sha256:7371597aa5fe8a93

The line at the top of this page pins the label git:20260709.9bf0b3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
