Skill4 starsChanged 8 months agoMITView on GitHub

SEO monitoring and alerting system. Tracks ranking fluctuations, competitor activity, technical health, content performance, and AI search visibility. Generates alerts at configurable thresholds. Use when user says "monitor", "alert", "watch", "track changes", "SEO dashboard", "weekly digest".

We split this skill into the rules it gives an agent

5 rules. About 0 are common, 5 are distinctive, and 0 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈5

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Check Google Search Status Dashboard

    line 33
  2. Distinctive:

    If confirmed update: document affected pages, defer changes 2-4 weeks until stable

    line 36
  3. Distinctive:

    Check if search intent shifted (SERP comparison)

    line 103
  4. Distinctive:

    Check for technical issues (speed, mobile, broken elements)

    line 105
  5. Distinctive:

    Test brand queries across ChatGPT, Perplexity, Gemini

    line 122

≈ “Common” is an estimate: at least 1 in 5 of the 308,232 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Google Update Correlation

When volatility spikes:

  1. Check Google Search Status Dashboard
  2. Cross-reference with industry volatility tools (SEMrush Sensor, Moz MozCast)
  3. Identify pattern: site-wide vs topical vs page-level
  4. If confirmed update: document affected pages, defer changes 2-4 weeks until stable

Competitor Activity Monitoring

Content Monitoring

  • New page detection: Compare competitor sitemap weekly, flag new URLs
  • Content updates: Track last-modified dates on competing pages
  • Topic expansion: Detect when competitors enter new topic areas
  • Publishing velocity: Track competitor content output rate

Ranking Monitoring

  • Position changes: Track competitor positions on your target keywords
  • New keyword entries: Detect when competitors rank for keywords they previously didn't
  • SERP feature captures: Monitor when competitors gain/lose featured snippets, PAA

Technical Monitoring

  • Speed changes: Detect CWV improvements/degradation
  • Schema additions: New structured data types deployed
  • Site structure changes: New sections, navigation changes, URL restructures

Backlink Monitoring

  • New links: Weekly check for competitor's newly acquired backlinks
  • Lost links: Opportunities when competitors lose high-quality links
  • Link velocity comparison: Your growth rate vs competitors

Technical Health Monitoring

Index Coverage Tracking

SignalThresholdSeverity
Indexed pages drop >10% weekly🟠 HighCheck robots.txt, noindex, server errors
Indexed pages drop >20%🔴 CriticalImmediate investigation
"Excluded" pages increase >20%🟡 MediumReview exclusion reasons
New crawl errors spike🟠 HighFix 5xx, check redirects

CWV Degradation Detection

MetricWarningCritical
LCP>2.5s (was passing)>4.0s
INP>200ms (was passing)>500ms
CLS>0.1 (was passing)>0.25

Trigger re-audit via seo-performance when any CWV degrades from "good" to "needs improvement".

Security Monitoring

  • Manual action notifications (GSC)
  • Malware injection detection (unexpected scripts, iframes)
  • SEO spam injection (hidden text, cloaked links, Japanese keyword hack)
  • SSL certificate expiration warnings (30/14/7 day alerts)

Content Decay Detection

  • Traffic decline: Organic sessions drop ≥20% for 3 consecutive weeks
  • Ranking erosion: Position drops ≥5 from peak
  • CTR decline: Click-through rate drops ≥30% from historical average

Decay Response Protocol

  1. Check if search intent shifted (SERP comparison)
  2. Evaluate if competitors published superior content
  3. Check for technical issues (speed, mobile, broken elements)
  4. Determine refresh strategy: update stats, add sections, restructure, or rewrite

Top Content Protection

  • Identify top 20 pages by organic traffic
  • Set tighter monitoring thresholds (any ranking drop ≥2)
  • Schedule proactive refreshes before decay (quarterly for evergreen, monthly for trending)

AI Search Visibility Monitoring

AI Overviews Tracking

  • Monitor target queries for AI Overview presence/absence
  • Track whether your content is cited in AI Overviews
  • Detect when competitors gain/lose AI citations
  • Measure citation share: your citations / total AI Overview appearances

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
