The Modern Customer Journey

Harvard Business Review found that 73% of consumers use multiple channels during shopping:

Discover on social media (Instagram, TikTok)

Research on search engines (Google)

Compare on review sites and marketplaces

Consider via retargeting ads

Purchase in app, website, or store

Engage through email, SMS, loyalty programs

Building an Omnichannel Strategy

Step 1: Map Customer Touchpoints

Document every interaction point:

Awareness Touchpoints:

• Social media ads
• Display advertising
• Video ads (YouTube, CTV)
• Influencer content
• Organic search
• PR and content

Consideration Touchpoints:

• Retargeting ads
• Email marketing
• Comparison shopping
• Review sites
• Product pages

Conversion Touchpoints:

• Shopping ads
• Cart abandonment emails
• Promotional offers
• In-store experience
• Sales team

Retention Touchpoints:

• Order confirmation
• Delivery updates
• Post-purchase follow-up
• Loyalty programs
• Customer service

Step 2: Unify Your Data

Data unification requirements:

Customer Data Platform (CDP) — Single customer view

Cross-device identity resolution — Connect devices to people

Unified measurement — Attribution across channels

Real-time activation — Act on data immediately

Step 3: Coordinate Messaging

Create message sequences that work together:

Touchpoint	Message	Goal

Discovery (Social)	Problem awareness	Generate interest
Education (YouTube)	Solution introduction	Build consideration
Consideration (Display)	Product benefits	Strengthen preference
Conversion (Search)	Offer + CTA	Drive purchase
Retention (Email)	Onboarding + value	Increase LTV

Step 4: Personalize at Scale

AI enables personalization across channels:

• Dynamic creative optimization — Personalized ads
• Triggered sequences — Behavioral responses
• Predictive targeting — Anticipate needs
• Real-time bidding — Channel and message selection

Channel Integration Tactics

Paid Social + Email Integration

Connect paid acquisition with owned channels:

Lead generation — Capture via social ads

Welcome sequence — Immediate email nurture

Suppression — Remove converters from acquisition

Reactivation — Retarget email non-openers via social

Search + Display Coordination

Complement high-intent with awareness:

Branded search — Capture demand

Non-brand search — Expand reach

Display retargeting — Re-engage abandoners

Display prospecting — Feed top of funnel

CTV + Digital Integration

Connected TV extends reach:

CTV brand awareness — Reach cord-cutters

Second-screen retargeting — Capture mobile attention

Sequential messaging — CTV exposure → digital conversion

Measurement — Cross-device attribution

Cross-Channel Marketing Intelligence

Building a Unified View

Components of cross-channel intelligence:

Component	Function

Data warehouse	Central data storage
Identity graph	Cross-device matching
Attribution platform	Journey analysis
Visualization	Dashboard and reporting
Activation	Real-time decisioning

Key Metrics to Track

Channel performance:

• ROAS by channel
• CAC by channel
• Assisted conversions
• Attribution weight

Customer journey:

• Path length (touchpoints to conversion)
• Time to conversion
• Channel sequence patterns
• Cross-device behavior

Business impact:

• Blended ROAS
• Customer lifetime value
• Retention rate
• Net promoter score

Overcoming Omnichannel Challenges

Challenge 1: Data Silos

Problem: Each platform has its own data, creating fragmented views. Solution:

• Implement a CDP or data warehouse
• Use server-side tracking for unified data collection
• Create consistent UTM and naming conventions
• Regular data reconciliation processes

Challenge 2: Measurement Complexity

Problem: Attribution across channels is difficult. Solution:

• Multi-touch attribution models
• Incrementality testing
• Marketing mix modeling (MMM)
• Holdout groups for validation

Challenge 3: Organizational Alignment

Problem: Teams operate in silos (social team, email team, etc.). Solution:

• Cross-functional collaboration frameworks
• Shared KPIs and incentives
• Regular cross-team planning sessions
• Unified customer journey ownership
