From the author

When the user wants to set up, improve, or audit analytics tracking and measurement. Also use when the user mentions "set up tracking," "GA4," "Google Analytics," "event tracking," "UTM parameters," "tag manager," "GTM," "analytics implementation," "tracking plan," "how do I measure this," "Mixpanel," "Segment," "are my events firing," or "analytics isn't working." Use this whenever someone asks how to know if something is working or wants to measure marketing results. For getting conversions into ad platforms (pixels, conversion tags, CAPI, server-side) and verifying they arrived, see conversion-tracking. For choosing attribution models, comparing multi-touch/MMM/incrementality, or reconciling conflicting numbers across tools, see attribution. For A/B test measurement, see ab-testing. Rate metrics divide matching closed windows — never full-period spend by partial-period results.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured approach to analytics implementation, emphasizing data quality, consistent naming conventions, and alignment with business goals. It guides users through the entire lifecycle of tracking—from defining what to measure based on decision-making needs, to technical implementation in tools like GA4 and GTM, and finally to validation and debugging. It includes specific patterns for UTM parameters, event naming, and data layer structures to ensure clean, reliable data collection.

What it does

  • Defines a tracking plan framework to map business questions to specific events.
  • Provides standardized event naming conventions (Object-Action) and property structures.
  • Offers implementation guidance for GA4 and Google Tag Manager.
  • Establishes best practices for UTM parameter strategy and traffic source tracking.
  • Includes a validation checklist for debugging event firing and data accuracy.
  • Provides principles for data quality, including reconciliation and observation window matching.

When to use it

  • When you need to set up tracking for a new website, app, or marketing campaign.
  • When you are auditing existing analytics to fix broken events or improve data quality.
  • When you need to define a consistent naming convention for events and properties.
  • When you need to implement or troubleshoot GA4 or GTM configurations.
  • When you are unsure how to measure specific marketing results or user behaviors.

Advantages

  • Ensures tracking is tied to actionable business decisions rather than vanity metrics.
  • Promotes consistency across teams through established naming and property patterns.
  • Reduces data corruption by enforcing strict validation and reconciliation practices.
  • Provides clear, repeatable patterns for complex setups like partner/influencer tracking.
  • Helps maintain privacy compliance by discouraging PII collection.

Usage examples

“How should I set up tracking for my new SaaS signup flow?”
The agent will help you define a tracking plan, identify key events like signup_started and signup_completed, and provide the GTM or GA4 implementation steps.
“My GA4 data looks wrong, how do I audit it?”
The agent will guide you through a validation checklist, including checking GTM triggers, using DebugView, and verifying event property population.
“What is the best way to track traffic from our newsletter partners?”
The agent will provide a UTM parameter strategy, including specific source/medium patterns and instructions for creating custom channel groups in GA4.
“How do I ensure my event tracking is consistent?”
The agent will introduce the Object-Action naming convention and provide a template for a tracking plan to document all events and properties.

Documentation by Corey Haines

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:

  1. Business Context - What decisions will this data inform? What are key conversions?

  2. Current State - What tracking exists? What tools are in use?

  3. 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

5. Compute, Don't Eyeball
  • Derive every total, rate, and delta from row-level data with a script or spreadsheet — never by scanning rows and summing mentally. One silently dropped row corrupts every figure downstream of it.

  • Cross-check each headline figure a second, independent way (a reconciliation total, a recomputation from a different grouping) before reporting it, and chase any mismatch to the exact row.

  • When a claim is about one segment — a single campaign, ad set, channel, or week — report that segment's own numbers. Never fold it into a neighboring group and let the group's total speak for it.

6. Match Observation Windows
  • A rate or efficiency metric divides a numerator and denominator that cover the same closed observation window. Never divide a full period's spend by a partial period's conversions or revenue — restate both over the weeks that actually have data, and say which weeks those are.

  • Cohort rates use only cohorts whose observation window has ended. A trial or signup still inside its window is pending, not failed — exclude it from the denominator and label it as pending rather than counting it against the rate.

7. Recommend Against the Stated Goal
  • Analysis ends in a recommendation, and the recommendation must be argued from the goal the brief states — the launch target, audience, revenue, or positioning objective — not only from what is operationally easiest. Name which stated goal each option serves and what it trades away.


Tracking Plan Framework

Structure
Event Name | Category | Properties | Trigger | Notes
---------- | -------- | ---------- | ------- | -----
Event Types
TypeExamples
PageviewsAutomatic, enhanced with metadata
User ActionsButton clicks, form submissions, feature usage
System EventsSignup completed, purchase, subscription changed
Custom ConversionsGoal completions, funnel stages

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


Event Naming Conventions

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

  • Keep provider-defined names when using automatic or recommended events (e.g. GA4 click, view_search_results, purchase). Map internal business names explicitly; naming a custom event does not make the provider collect it automatically.

Best Practices
  • Use consistent property names

  • Include relevant context

  • Don't duplicate automatic properties

  • Avoid PII in properties


GA4 Implementation

Quick Setup
  1. Create GA4 property and data stream

  2. Install gtag.js or GTM

  3. Enable enhanced measurement

  4. Configure custom events

  5. Mark conversions in Admin

Event Example
// GA4's recommended sign_up event, not a custom name, so it feeds built-in reports.
// Your tracking plan can still call this signup_completed; map the name explicitly.
gtag('event', 'sign_up', {
  'method': 'email',
  'plan': 'free'
});

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

TagsCode that executes (GA4, pixels)
TriggersWhen tags fire (page view, click)
VariablesDynamic values (click text, data layer)
Data Layer Pattern
dataLayer.push({
  'event': 'form_submitted',

  'form_location': 'footer'
});

UTM Parameter Strategy

Standard Parameters
ParameterPurposeExample
utm_sourceTraffic sourcegoogle, newsletter
utm_mediumMarketing mediumcpc, email, social
utm_campaignCampaign namespring-sale
utm_contentDifferentiate versionshero-cta
utm_termPaid search keywordsrunning-shoes
Naming Conventions
  • Lowercase everything. GA4 treats LinkedIn and linkedin as two sources, and the split never merges back.

  • Hyphens between words. No spaces, underscores, or +. Pick one separator for the whole company; this skill uses hyphens.

  • One spelling per source. linkedin, never also li or linkedin.com. Keep the allowed values in a shared sheet and build links from it.

  • No personal data. Never put emails, names, phone numbers, or user IDs in a UTM. They land in analytics reports and in referrer logs, and Google's terms prohibit sending PII to GA4.

  • Specific but short: blog-footer-cta, not cta1.

  • Test the final URL. Shorteners and redirects can drop or double parameters. Click the live link and check the landing URL before the campaign ships.

UTM Patterns by Partner Type

Partner links break most often because each deal gets named on the spot. Fix the pattern per partner type once: utm_medium names the kind of deal, utm_source names who sent the traffic.

Partner typeutm_sourceutm_mediumutm_campaignutm_content
Newsletter{partner} (one per partner, across all their publications)newsletter{partner}-{publication}-{yyyy}-{mm}{placement}-{yyyy-mm-dd}
Creator (YouTube, LinkedIn, TikTok){platform}creator{creator}{post-date} or the video ID
Podcast{podcast}podcast{podcast}-{yyyy}-{mm}{spot}-{yyyy-mm-dd} (pre-roll, mid-roll)
Affiliate{partner}affiliate{partner}-affiliateplacement, if they have several
Community{community}community{community}-{program}the channel or post, if known
  • Use creator as the medium for paid creator deals, not social (which mixes them with your organic posts) or video (which mixes them with paid video ads). The platform goes in utm_source.

  • One link per placement. A newsletter that runs you on two dates gets two links, so each date's clicks stay separate. The monthly utm_campaign rolls them up.

  • Add a custom channel group in GA4. GA4's default grouping sends mediums like newsletter, creator, podcast, and community to Unassigned (only affiliate and email map to a default channel). Create a channel group with a rule per medium so partner traffic shows up as its own channels.

  • Podcast and video links often aren't clickable, so pair the UTM link with a promo code or vanity URL. See influencer-marketing for the rest of partner measurement.

The partner-type pattern is adapted from Wispr Flow's link-creator skill (MIT), published in the skills.marketing library.

Traffic From AI Assistants

You can't tag links that ChatGPT, Claude, Perplexity, Gemini, or Copilot put in their answers. Some of those visits arrive with a referrer (chatgpt.com, perplexity.ai) or an assistant-added utm_source; many arrive as direct, or come later through a branded search.

  • Add a GA4 channel group rule that matches known assistant referrers and sources into an "AI assistants" channel, and update the list as new assistants appear.

  • Treat that channel as the floor. Assistant-driven visits that show up as direct or branded search can be most of the effect, and they won't carry the referrer.

  • For measuring the full effect (exposure, delayed visits, and longer attribution windows), see ai-seo. For reconciling it with other sources, see attribution.
