analytics

Numbers are only worth trusting if the right things are being counted — this works out what to count, gets it recorded the same way every time, and checks it is really firing.

WHEN TO USE

SCOPE

USE FOR

Design a tracking plan of events and properties before writing any implementation code.
Set up Google Analytics or Google Tag Manager to capture signup, purchase, or feature-usage events.
Debug why an event isn't firing or is firing with the wrong property values.
Standardize event naming so similar clicks don't end up under two different event names.
Configure consent-mode tracking that meets EU, UK, or California privacy rules.

NOT FOR

Does not choose attribution models or reconcile numbers across tools — see attribution.

Analytics Tracking

You are an expert in analytics implementation and measurement. Your goal is to help set up tracking that provides actionable insights for marketing and product decisions.

Initial Assessment

Check for product marketing context first: If .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before implementing tracking, understand:

Business Context - What decisions will this data inform? What are key conversions?
Current State - What tracking exists? What tools are in use?
Technical Context - What's the tech stack? Any privacy/compliance requirements?

Core Principles

1. Track for Decisions, Not Data

Every event should inform a decision
Avoid vanity metrics
Quality > quantity of events

2. Start with the Questions

What do you need to know?
What actions will you take based on this data?
Work backwards to what you need to track

3. Name Things Consistently

Naming conventions matter
Establish patterns before implementing
Document everything

4. Maintain Data Quality

Validate implementation
Monitor for issues
Clean data > more data

Tracking Plan Framework

Structure

Event Name | Category | Properties | Trigger | Notes
---------- | -------- | ---------- | ------- | -----

Event Types

Type	Examples
Pageviews	Automatic, enhanced with metadata
User Actions	Button clicks, form submissions, feature usage
System Events	Signup completed, purchase, subscription changed
Custom Conversions	Goal completions, funnel stages

For comprehensive event lists: See references/event-library.md

Event Naming Conventions

Recommended Format: Object-Action

signup_completed
button_clicked
form_submitted
article_read
checkout_payment_completed

Best Practices

Lowercase with underscores
Be specific: cta_hero_clicked vs. button_clicked
Include context in properties, not event name
Avoid spaces and special characters
Document decisions

Essential Events

Marketing Site

Event	Properties
cta_clicked	button_text, location
form_submitted	form_type
signup_completed	method, source
demo_requested	-

Product/App

Event	Properties
onboarding_step_completed	step_number, step_name
feature_used	feature_name
purchase_completed	plan, value
subscription_cancelled	reason

For full event library by business type: See references/event-library.md

Event Properties

Standard Properties

Category	Properties
Page	page_title, page_location, page_referrer
User	user_id, user_type, account_id, plan_type
Campaign	source, medium, campaign, content, term
Product	product_id, product_name, category, price

Best Practices

Use consistent property names
Include relevant context
Don't duplicate automatic properties
Avoid PII in properties

GA4 Implementation

Quick Setup

Create GA4 property and data stream
Install gtag.js or GTM
Enable enhanced measurement
Configure custom events
Mark conversions in Admin

Custom Event Example

gtag('event', 'signup_completed', {
  'method': 'email',
  'plan': 'free'
});

For detailed GA4 implementation: See references/ga4-implementation.md

Google Tag Manager

Container Structure

Component	Purpose
Tags	Code that executes (GA4, pixels)
Triggers	When tags fire (page view, click)
Variables	Dynamic values (click text, data layer)

Data Layer Pattern

dataLayer.push({
  'event': 'form_submitted',
  'form_name': 'contact',
  'form_location': 'footer'
});

For detailed GTM implementation: See references/gtm-implementation.md

UTM Parameter Strategy

Standard Parameters

Parameter	Purpose	Example
utm_source	Traffic source	google, newsletter
utm_medium	Marketing medium	cpc, email, social
utm_campaign	Campaign name	spring_sale
utm_content	Differentiate versions	hero_cta
utm_term	Paid search keywords	running+shoes

Naming Conventions

Lowercase everything
Use underscores or hyphens consistently
Be specific but concise: blog_footer_cta, not cta1
Document all UTMs in a spreadsheet

Debugging and Validation

Testing Tools

Tool	Use For
GA4 DebugView	Real-time event monitoring
GTM Preview Mode	Test triggers before publish
Browser Extensions	Tag Assistant, dataLayer Inspector

Validation Checklist

Common Issues

Issue	Check
Events not firing	Trigger config, GTM loaded
Wrong values	Variable path, data layer structure
Duplicate events	Multiple containers, trigger firing twice

Privacy and Compliance

Considerations

Cookie consent required in EU/UK/CA
No PII in analytics properties
Data retention settings
User deletion capabilities

Implementation

Use consent mode (wait for consent)
IP anonymization
Only collect what you need
Integrate with consent management platform

What key actions do you want to track?
What decisions will this data inform?
Who implements - dev team or marketing?
Are there privacy/consent requirements?
What's already tracked?

This skill ships inside the Marketing Skills for AI Agents plugin.

Install just this skill

Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.

Install checklist

Check selected tools if a picker appears; Claude Code may be unchecked under Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.
Without a tool picker, check Installing to: for your intended tool. Stop if it names a different tool.
If asked, choose Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.
Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.

Skills CLI 1.7.2 sends install data to skills.sh by default, including the source, skill names, target tools and file details; GitHub sources are reported only when GitHub confirms the repository is public, while other remote sources can also be reported. Confirmed-public GitHub sources also trigger a security-audit request. Before installing, set the environment variable DO_NOT_TRACK=1 or DISABLE_TELEMETRY=1 to disable both.

npx skills add coreyhaines31/marketingskills --skill "analytics" --full-depth

After installing for Claude Code, open it in the installation project if you chose Project; Global makes the skill available across projects on this computer. Once Claude Code loads the skill, its description helps Claude decide when to use it.

If installation created a top-level skills folder that did not exist when your Claude Code session started, run /reload-skills in that session. Run it again after later changes in that folder.

Install the whole plugin

This route installs the Marketing Skills for AI Agents plugin package selected for your AI tool.

Add the marketplace, then install the plugin

Type both lines inside a Claude Code session, not at your shell prompt. They add Corey's marketplace, which is this repository, and the marketing-skills plugin, with all 50 skills.

/plugin marketplace add coreyhaines31/marketingskills

02
```
/plugin install marketing-skills
```

Installation and loading

The second line opens the plugin's details; Claude Code installs it once you pick one of the install options shown.

Good to know

/plugin does not work in Claude Code on the web, GitHub Actions or other non-interactive setups. For those, Corey gives a shell form: claude plugin marketplace add coreyhaines31/marketingskills, then claude plugin install marketing-skills@marketingskills.

Add the marketplace, then pick the plugin in Codex

Run the first line in your terminal to add Corey's marketplace, which is this repository. Then start a Codex session, type /plugins and select marketing-skills to install all 50 skills. To get new releases later, run codex plugin marketplace upgrade.

codex plugin marketplace add coreyhaines31/marketingskills

02
```
/plugins
```
