Platform-Specific Setup

Meta (Facebook & Instagram)

META ADS UTM CONFIGURATION
============================

WHERE TO CONFIGURE:
├── Ad Level → Destination → URL Parameters
├── Or: Campaign/Ad Set Level → Tracking → URL Parameters

RECOMMENDED TEMPLATE:
utm_source=facebook
&utm_medium=paid-social
&utm_campaign={{campaign.name}}
&utm_content={{ad.name}}
&utm_term={{adset.name}}

DYNAMIC PARAMETERS META:
┌─────────────────────────┬────────────────────────────────────┐
│ Parameter               │ What it contains                   │
├─────────────────────────┼────────────────────────────────────┤
│ {{campaign.name}}       │ Campaign name                      │

&utm_medium=paid-social
&utm_campaign={{campaign.name}}
&utm_content={{ad.name}}_{{placement}}
&utm_term={{adset.name}}

NOTE:
├── fbclid is automatically added by Meta
├── GA4 does NOT recognize fbclid for attribution
├── UTM is essential for GA4 tracking
├── Test in Events Manager for parameter validation
└── Meta Pixel is still needed for Meta Attribution

LinkedIn Ads

LINKEDIN ADS UTM CONFIGURATION
================================

WHERE TO CONFIGURE:
├── Campaign Manager → Campaign → Ad → Destination URL
├── Or: Bulk upload via campaign CSV

RECOMMENDED TEMPLATE:
utm_source=linkedin
&utm_medium=paid-social
&utm_campaign={{CAMPAIGN_NAME}}
&utm_content={{CREATIVE_NAME}}
&utm_term={{CAMPAIGN_GROUP_NAME}}

DYNAMIC PARAMETERS LINKEDIN:

└─────────────────────────┴────────────────────────────────────┘

LINKEDIN INSIGHT TAG:
─────────────────────
In addition to UTM, install LinkedIn Insight Tag:
├── Required for LinkedIn Attribution
├── Required for LinkedIn Audiences
├── Required for Conversion Tracking
└── Implement via GTM or directly

<!-- LinkedIn Insight Tag (in GTM or head) -->
<script type="text/javascript">
_linkedin_partner_id = "XXXXXX";
// ... rest of Insight Tag code
</script>

NOTE:
├── LinkedIn adds li_fat_id (for first-party tracking)
├── This is NOT sufficient for GA4
├── UTM is essential for GA4 attribution
└── B2B: consider longer attribution windows

GA4 Channel Groupings Impact

UTM → GA4 CHANNEL GROUPING MAPPING
====================================

HOW GA4 DETERMINES CHANNELS:
GA4 looks at source/medium combination:

┌─────────────────────────────────┬─────────────────────────────┐
│ Source/Medium                   │ GA4 Default Channel         │
├─────────────────────────────────┼─────────────────────────────┤
│ facebook / paid-social          │ Paid Social                 │
│ facebook / cpc                  │ Paid Social (cpc matched)   │
│ linkedin / paid-social          │ Paid Social                 │
│ tiktok / paid-social            │ Paid Social                 │
│ facebook / organic-social       │ Organic Social              │
│ google / cpc                    │ Paid Search                 │
│ google / organic                │ Organic Search              │
│ newsletter / email              │ Email                       │
│ (direct) / (none)               │ Direct                      │
│ example.com / referral          │ Referral                    │
└─────────────────────────────────┴─────────────────────────────┘

COMMON MISTAKES:
────────────────
WRONG: utm_medium=social
   → GA4 sees this as "Organic Social" instead of "Paid Social"

CORRECT: utm_medium=paid-social
   → GA4 puts in "Paid Social" channel

WRONG: utm_medium=Facebook
   → Case mismatch, inconsistent data

CORRECT: utm_medium=paid-social
   → Consistent with naming convention

MEDIUM VALUES THAT TRIGGER PAID SOCIAL:
├── paid-social
├── paidsocial
├── paid_social
├── cpc (if source is a social platform)
├── ppc (if source is a social platform)
└── cpm (if source is a social platform)

Tracking Verification

UTM TRACKING VERIFICATION STEPS
=================================

STEP 1: URL VALIDATION (before launch)
───────────────────────────────────────
┌────┬────────────────────────────────────────────────────────────┐

│    │ https://ga-dev-tools.google/campaign-url-builder/         │
├────┼────────────────────────────────────────────────────────────┤
│ 2  │ Test URL in browser - does page load correctly?           │
├────┼────────────────────────────────────────────────────────────┤
│ 3  │ Check special characters are encoded                      │
├────┼────────────────────────────────────────────────────────────┤
│ 4  │ Verify no spaces or uppercase                             │
└────┴────────────────────────────────────────────────────────────┘

STEP 2: GA4 DEBUGVIEW TEST
───────────────────────────

├────┼────────────────────────────────────────────────────────────┤
│ 4  │ Check in DebugView:                                       │
│    │ - page_view event appears                                 │
│    │ - campaign, source, medium parameters correct             │
└────┴────────────────────────────────────────────────────────────┘

STEP 3: REALTIME VERIFICATION
──────────────────────────────
┌────┬────────────────────────────────────────────────────────────┐
│ 1  │ GA4 → Reports → Realtime                                  │

├────┼────────────────────────────────────────────────────────────┤
│ 3  │ Verify source/medium/campaign correct                     │
├────┼────────────────────────────────────────────────────────────┤
│ 4  │ Check that channel grouping is correct                    │
└────┴────────────────────────────────────────────────────────────┘

├────┼────────────────────────────────────────────────────────────┤
│ 3  │ Verify sessions and events appear                         │
├────┼────────────────────────────────────────────────────────────┤
│ 4  │ Check channel grouping is correct                         │
└────┴────────────────────────────────────────────────────────────┘

2026: Cross-Channel Budgeting in GA4

GA4 CROSS-CHANNEL BUDGETING (BETA, 2026)
==========================================

WHAT IT IS:
├── A budget planning tool inside GA4 that combines data from multiple ad platforms
├── Supported platforms: Google Ads (native), Meta, LinkedIn, TikTok, Snapchat (import)
├── Location: GA4 → Advertising → Cross-channel budgeting
└── Uses GA4's data-driven attribution as the single source of truth

WHY IT MATTERS FOR TRACKING SETUP:
├── Consistent UTMs are critical for this feature to work correctly
├── Meta, LinkedIn, TikTok data must be connected via GA4 product links
├── Platform performance is compared using GA4 attributed conversions (Key Events)
└── Accurate channel groupings are prerequisite (Paid Social must not fall into Unassigned)

SETUP REQUIREMENTS:
├── All paid platforms must have UTMs on every ad
├── Channel groupings must be clean (Unassigned < 5%)
└── Key Events must be correctly configured with values

MCP TOOL - Check cross-channel attribution:

ga4_run_report( property_id="YOUR_PROPERTY_ID", metrics=["keyEvents", "totalRevenue"], dimensions=["sessionDefaultChannelGroup", "sessionCampaignName"], start_date="30daysAgo", end_date="yesterday" )

Output: Cross-Platform Tracking Template
