Find pages quietly losing search traffic before they fall off page one, and decide which are worth refreshing. Use when someone asks which content needs updating, what to refresh, whether pages are declining, or wants a proactive content-maintenance list. Requires the aeo-toolkit aeo-search MCP server.
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
# Detecting content decay
Pages rarely collapse overnight. They bleed traffic over weeks, and by the time it shows up
in a monthly report the rankings are usually gone. The point of this skill is to catch that
while the page is still on page one, when a refresh still works.
## Finding candidates
1. Call `list_gsc_sites` and confirm the property.
2. Call `gsc_decay`. The defaults (28-day windows, 100 baseline impressions, 20% decline) are
a reasonable start.
- **Short windows are noisy.** A 7-day window will surface normal week-to-week variance as
decay. Prefer 28 days or more unless investigating something specific.
- **Raise `minDeclinePct` if the list is too long**, rather than cutting it arbitrarily.
A shorter list of worse cases is more useful than a truncated list of mild ones.
The tool compares the recent window against the equal-length window immediately before it,
with no overlap.
## Reading the results
`lostRank` is the field that matters most:
- **`lostRank: true`** — clicks down *and* position slipped. Competitors are outranking the
page, or its content has aged out of relevance. This is the actionable case and is where a
refresh pays.

How to install
mdr add advance-labs/aeo-toolkit/seo-content-decay@sha256:34782a0812d60b27The line at the top of this page pins the label git:20261021.d6e9f7d, 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.
