Content Decay Kit — for agencies with 5–50 client properties

Know which client article is dying — before your client notices

Content decay is invisible until a client calls. This kit watches every property you manage through Google's official Search Console API, flags the pages losing clicks — with a noise floor, so junk alerts don't exist — and renders a white-label weekly digest: your agency's name on top, refresh priorities P1–P3 inside. One payment of ฿1,990 — then it runs on your own host, free, forever.

What's inside the kit

One zip, zero npm dependencies, no database, no vendor login — one Node script on your own host, watching your clients' Search Console.

Official GSC data

Reads each property via the Search Console API

Read-only scope, Google's official API. You add your own (free) service account as a Viewer on each property — about two minutes per client — and the script reads clicks, impressions and position per page.

Decay math with a noise floor

28 days vs a 92-day baseline, honestly normalized

Clicks are compared per day so the different window lengths can't fake a trend. A page flags at −20% or worse — and only if its baseline cleared 200 impressions, so low-volume pages never cry wolf.

The why, not just the what

Ranking slipped, seen-not-clicked, or demand cooled

Every flagged page is classified: position lost, CTR lost while demand held, or search demand itself cooled — each with a matching refresh suggestion in the digest.

White-label digest

Your agency's name on every client report

Each client gets their own weekly HTML digest — logo slot, refresh priorities P1–P3, a "what happens next" checklist — print-ready, script-free, and free of any vendor name.

Cron + Actions

Weekly schedule, copy-paste

Ready-made crontab lines for any host, or a bundled GitHub Actions workflow on a private repo — free. Optional Slack-style webhook nudge when P1 pages appear.

Sell it

14-day playbook + single-agency license

How to pitch the digest as a $29–99/month care-plan add-on — one client covers the kit. The license covers every client property your agency serves.

Self-hosted on purpose: your credentials, your data, your brand

Your Google credentials — never ours. You create the free Google service account, you add it to Search Console as a Viewer, and the key stays in your config folder. There is no account with us and no hosted service to trust: stop using the kit, delete the key, done.

Client data stays in your out/ folder. The script talks only to Google's documented API endpoints and writes the dashboard, the digests and the run history on your machine. No telemetry, no third party anywhere in your clients' data.

Monitoring, not another optimization suite. This kit deliberately does not score content, suggest keywords, or promise rankings — it tells you which page lost traffic, why, and what to refresh first. That is the deliverable your retainer was missing.

How it works

From zip to a client-ready digest in three steps. Try before you buy the workflow: node decay/decay.mjs --demo runs the whole pipeline on demo data, no credentials.

Step 1

Connect your clients

Create one service account, add it as a Viewer on each Search Console property, list the properties in properties.json. Your credentials, your config.

Step 2

Run it weekly

Paste a crontab line or push the bundled GitHub Actions workflow. The script scans every property and rewrites the dashboard and the digests.

Step 3

Send the digest

Attach the client's white-label digest to your weekly email — your logo, the flagged pages, the refresh plan — before anyone has to ask.

One price. You own it.

No per-property fee, no per-seat fee, no subscription — and it runs on free infrastructure.

Frequently asked questions

What does the license cover?

A single-agency commercial license: one buyer (a person or a company) runs the kit for all of their own client properties, forever. The digests and dashboards you generate are yours to brand, print and deliver. Redistributing or reselling the kit files themselves is not allowed — each agency needs its own license.

Do I have to share my Google access with you?

No — and the kit wouldn't accept it anyway. You create your own free Google service account, add it as a Viewer on the properties you monitor, and the key lives in your config folder. The script talks straight to Google's official Search Console API from your machine; there is no server of ours in the middle and nothing to revoke later except deleting the key.

Do I get updates?

Yes — every v1.x update (detection refinements, digest templates, scheduling recipes) is free. Re-download any time from your purchase page with your email and password. If a v2.0 ever ships, existing buyers get a clear upgrade path — never a surprise paywall.

What is the refund policy?

If the kit doesn't fit how you work, email zicula06@gmail.com within 14 days of purchase and we'll refund you in full — the zip is yours to keep or delete. One refund per purchase; we only ask for optional feedback.

How is this different from Semrush, Ahrefs or Surfer?

Those are optimization and rank-tracking suites — excellent at telling you what to build, priced per seat per month. This kit deliberately does one narrow thing they don't put front and center: portfolio-level decay monitoring on official Search Console data, with a client-facing white-label weekly digest as the output. It complements them; it doesn't replace them.

What does my client actually see?

Only their own weekly digest — your agency name and logo on top, their flagged pages with priorities and refresh suggestions, a "what happens next" checklist. No vendor name, no "powered by", no scripts, and no data about your other clients. The all-clients dashboard stays internal.

Next week's digest could carry your logo
