Introducere: De Ce Analytics E-Commerce Este Diferit Vezi și: Ghid complet E-Commerce, Product Page Optimization, Marketing Analytics, Ghid complet Digital Marketing.
"You can't improve what you don't measure." În 2026, magazine-le online de succes sunt conduse de date, nu intuiție. Diferența între un magazin care crește cu 20% pe an și unul care crește cu 200% este decision-making bazat pe analytics.
Provocări Specifice E-Commerce
- Multe touchpoints: User journey poate include 5-10+ interacțiuni înainte de conversie
- Attribution complexity: Care canal merită credit pentru vânzare?
- Customer lifecycle: Nu doar first purchase contează - LTV (Lifetime Value) e crítica
- Product performance: Thousands de SKU-uri - care produse merg, care nu?
- Cohort behavior: Clienți din ianuarie vs iulie se comportă diferit?
În acest ghid complet:
- Google Analytics 4 (GA4) setup perfect pentru e-commerce
- KPIs esențiali și cum să-i urmărești
- Conversion tracking și funnel analysis
- Customer segmentation și cohort analysis
- Product performance și inventory optimization
- Customer Lifetime Value (CLV) și retention metrics
- Attribution modeling - care canale funcționează?
- Tools ecosistem: GA4 + Hotjar + Dashboard custom
- Raportare și actionable insights
1. Google Analytics 4: Foundation Setup
De Ce GA4, Nu Universal Analytics?
UA (Universal Analytics) a murit 1 iulie 2023. GA4 este singura opțiune în 2026.
Diferențe majore GA4 vs UA:
- Event-based tracking (nu pageview-centric)
- Cross-platform (web + app unified)
- Machine learning predictions built-in
- Privacy-centric (cookieless future-ready)
- Better e-commerce reports (native)
E-Commerce Setup Pas cu Pas
Step 1: Create GA4 Property
Google Analytics → Admin → Create Property
→ Property name: "TechStore.ro - Magazin Online"
→ Time zone: Europe/Bucharest
→ Currency: RON
Step 2: Data Stream Setup
Admin → Data Streams → Add Stream → Web
→ Website URL: https://techstore.ro
→ Stream name: "TechStore Web"
→ ✓ Enable Enhanced Measurement
Step 3: E-Commerce Settings
Admin → Data Display → E-commerce Settings
→ ✓ Enable e-commerce
→ ✓ Enable enhanced e-commerce reporting
Step 4: Install gtag.js (Google Tag)
<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=G-XXXXXXXXXX"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag(){dataLayer.push(arguments);}
gtag('js', new Date());
gtag('config', 'G-XXXXXXXXXX');
</script>
Recomandare: Folosește Google Tag Manager în loc de hard-coded tags - mult mai flexibil.
E-Commerce Events Critical
GA4 E-commerce events (implementează toate):
1. view_item_list (category page view):
gtag('event', 'view_item_list', {
item_list_id: "related_products",
item_list_name: "Related Products",
items: [{
item_id: "SKU_12345",
item_name: "MacBook Pro 16''",
price: 19999,
item_category: "Laptopuri",
item_category2: "Gaming",
quantity: 1
}]
});
2. view_item (product page view):
gtag('event', 'view_item', {
currency: "RON",
value: 19999,
items: [{
item_id: "SKU_12345",
item_name: "MacBook Pro 16''",
price: 19999,
// ... full product data
}]
});
3. add_to_cart:
gtag('event', 'add_to_cart', {
currency: "RON",
value: 19999,
items: [/* product data */]
});
4. begin_checkout:
gtag('event', 'begin_checkout', {
currency: "RON",
value: 19999,
items: [/* all cart items */]
});
5. add_payment_info (payment method selected):
gtag('event', 'add_payment_info', {
currency: "RON",
value: 19999,
payment_type: "Credit Card",
items: [/* cart items */]
});
6. purchase (MOST IMPORTANT):
gtag('event', 'purchase', {
transaction_id: "T_12345",
value: 19999,
tax: 3192, // VAT
shipping: 0,
currency: "RON",
items: [{
item_id: "SKU_12345",
item_name: "MacBook Pro 16''",
price: 19999,
quantity: 1
}]
});
⚠️ CRITICAL: transaction_id trebuie să fie unique - altfel duplicates!
7. refund (pentru returns):
gtag('event', 'refund', {
transaction_id: "T_12345", // same ID ca la purchase
value: 19999,
currency: "RON"
});
Testing Event Implementation
Tools:
- GA4 DebugView (real-time event testing)
- Admin → DebugView → vezi events live
- Google Tag Assistant (Chrome extension)
- Browser console: Verifică
dataLayerarray
Checklist validation:
- All 7 events se trimit corect
- Product data completă (item_id, name, price, category)
- Transaction IDs sunt unique
- Currency corect (RON)
- Values corespund prețurilor reale
2. KPIs Esențiali E-Commerce
Revenue Metrics (Top Priority)
1. Total Revenue:
- Formula: Sum of all purchase values
- Target: Growth YoY (year-over-year): +20-50%
2. Average Order Value (AOV):
- Formula: Total Revenue / Number of Orders
- Benchmark: €50-150 pentru retail general, €200-500 pentru electronics
- Target: Increase cu 10-15% YoY
3. Revenue Per Visitor (RPV):
- Formula: Total Revenue / Total Visitors
- Critical metric - combină traffic ȘI conversie
- Benchmark: €1-5 (varies by industry)
4. Customer Lifetime Value (CLV):
- Formula: Average Order Value × Purchase Frequency × Customer Lifespan
- Example: €100 AOV × 3 orders/year × 4 years = €1,200 CLV
- Critical pentru: Cât poți cheltui pentru customer acquisition
Conversion Metrics
5. Conversion Rate:
- Formula: (Transactions / Sessions) × 100
- Benchmark e-commerce: 1-3% average, 3-5% good, 5%+ excellent
- Variază mult by traffic source (organic > paid usually)
6. Cart Abandonment Rate:
- Formula: 1 - (Transactions / Add to Cart Events)
- Benchmark: 60-75% (lower is better)
- Target: < 60% prin optimizations
7. Checkout Abandonment:
- Formula: 1 - (Transactions / Begin Checkout Events)
- Benchmark: 20-30%
- Critical: Dacă peste 30%, serious checkout issues
Traffic Metrics
8. Sessions:
- Total vizite (session = 30min window)
- Breakdown by source: Organic, Direct, Referral, Paid, Social
9. Unique Visitors:
- Câte persoane distincte
- New vs Returning: Balans sănătos e 60% new / 40% returning
10. Traffic Sources Performance:
Source/Medium Sessions Revenue Conv Rate ROAS
──────────────────────────────────────────────────────────
Organic Search 5,000 €15,000 3.5% ∞
Google Ads 2,000 €8,000 2.8% 4.2x
Facebook Ads 1,500 €3,000 1.5% 2.1x
Email 800 €6,000 6.2% ∞
Direct 3,000 €12,000 4.1% ∞
Product Performance
11. Product Views:
- Câte views per produs
- Identifică products with high views but low conversions (optimization opportunity)
12. Product Revenue:
- Top products by revenue
- 80/20 rule: Often 20% products = 80% revenue
13. Product Conversion Rate:
- (Product Purchases / Product Views) × 100
- Identifică best converters și worst converters
14. Add-to-Cart Rate:
- (Add to Cart / Product Views) × 100
- Benchmark: 5-15%
- Dacă sub 5%, product page needs optimization
Customer Retention
15. Repeat Purchase Rate:
- Formula: (Customers with 2+ Orders / Total Customers) × 100
- Benchmark: 20-30% (varies dramatically by industry)
- Critical pentru: Long-term profitability
16. Purchase Frequency:
- Formula: Total Orders / Total Unique Customers
- Benchmark: 1.5-3 orders/customer/year
17. Customer Retention Rate:
- Formula: ((Customers End - New Customers) / Customers Start) × 100
- Target: > 80% retention
3. Conversion Funnel Analysis
Building the Funnel in GA4
Standard E-Commerce Funnel:
Step 1: All Visitors 100% (10,000 sessions)
↓
Step 2: Product View 40% (4,000 views)
↓
Step 3: Add to Cart 10% (1,000 adds)
↓
Step 4: Begin Checkout 7% (700 checkouts)
↓
Step 5: Add Payment Info 5% (500 payments)
↓
Step 6: Purchase 3% (300 purchases)
Drop-off Analysis:
- Product → Cart: 60% drop → Product page optimization needed
- Cart → Checkout: 30% drop → Cart page issues sau shipping concerns
- Checkout → Payment: 28% drop → Checkout form too complex
- Payment → Purchase: 40% drop → Payment failures sau trust issues
Cum să Creezi Funnel în GA4
Reports → Engagement → All Events → Funnel Exploration
Step 1: view_item (product view)
Step 2: add_to_cart
Step 3: begin_checkout
Step 4: add_payment_info
Step 5: purchase
Insights actionable:
- Biggest drop-off: Focus aici
- Segment by device: Mobile vs desktop funnel poate fi dramatically different
- Segment by source: Organic vs paid - care convertește better?
4. Customer Segmentation & Cohort Analysis
RFM Segmentation (Recency, Frequency, Monetary)
Formula:
- Recency: Cât de recent au cumpărat (0-30 days = 5 points, 30-60 = 4, etc.)
- Frequency: Câte comenzi au făcut (1 order = 1, 5+ orders = 5)
- Monetary: Cât au cheltuit total (< €50 = 1, €500+ = 5)
Customer segments:
RFM Score Segment Action
──────────────────────────────────────────────────────
555 Champions VIP treatment, exclusive offers
544 Loyal Customers Upsell, cross-sell
333 Regular Engage, loyalty program
221 At-Risk Win-back campaigns
111 Lost Reactivation or let go
Implementation în GA4:
- Create audiences based on: days since last purchase, total transactions, total revenue
- Use în remarketing campaigns
Cohort Analysis: Customer Behavior Over Time
Example cohort report:
Cohort Month 0 Month 1 Month 2 Month 3 Month 6
(Acquisition)
──────────────────────────────────────────────────────────────
Jan 2026 100% 35% 28% 22% 15%
Feb 2026 100% 32% 25% 20% —
Mar 2026 100% 38% 30% — —
Insights:
- Retention improving? Mar cohort retains better than Jan → marketing/product improvements working
- Drop-off when? Month 1-2 biggest drop → focus retention efforts here
Cum să creezi în GA4:
Reports → Retention → Create Cohort
Dimension: First user source/medium
Metric: Active users (sau Purchase revenue)
5. Product Performance Deep-Dive
Product Dashboard Essential
Metrics per product:
Product Views Add-to-Cart ATC Rate Purchases Conv Rate Revenue
────────────────────────────────────────────────────────────────────────────────
MacBook Pro 5,000 800 16% 150 3% €2,999,850
iPhone 15 8,000 1,200 15% 200 2.5% €1,600,000
AirPods Pro 3,000 600 20% 180 6% €448,200
Analysis:
- AirPods: Highest conversion rate (6%) - star product, promote more!
- iPhone: High traffic dar low conversion (2.5%) - pricing issue? Competition? Reviews?
- MacBook: Good performer, but poate creștem traffic
Inventory Optimization
Stock-out impact:
-- Pseudo-query pentru analysis
SELECT
product_id,
SUM(revenue) as total_revenue,
SUM(CASE WHEN in_stock = FALSE THEN potential_revenue ELSE 0) as lost_revenue,
(lost_revenue / (total_revenue + lost_revenue)) * 100 as opportunity_loss_pct
FROM product_analytics
Insight: Dacă MacBook e out-of-stock 15% din timp → pierzi 15% revenue potential → restock priority
Product Recommendations Performance
Track performance:
- "Frequently bought together" adds
- "You may also like" clicks
- Upsell revenue attributed to recommendations
A/B test:
- Recommendation algorithm A vs B
- Placement (sidebar vs below description)
6. Customer Lifetime Value (CLV) Optimization
Calculating CLV
Formula simplificată:
CLV = (Average Order Value) × (Purchase Frequency) × (Customer Lifespan)
Example:
- AOV: €120
- Purchase Frequency: 2.5 times/year
- Lifespan: 3 years
- CLV = €120 × 2.5 × 3 = €900
Improving CLV: 3 Levers
1. Increase AOV:
- Upsells ("Upgrade to Pro version +€50")
- Cross-sells ("Customers also bought X")
- Free shipping thresholds ("Add €20 for free shipping")
- Bundles ("Buy 3, save 15%")
Impact: AOV €120 → €140 = CLV €900 → €1,050 (+17%)
2. Increase Purchase Frequency:
- Email marketing (monthly newsletters, promotions)
- Loyalty programs ("Buy 5, get 6th free")
- Subscriptions (consumables)
- Seasonal campaigns
Impact: Frequency 2.5 → 3 times/year = CLV €900 → €1,080 (+20%)
3. Increase Lifespan (Retention):
- Excellent customer service
- Quality products (low return rate)
- Engagement content (blog, videos)
- Community building
Impact: Lifespan 3 → 4 years = CLV €900 → €1,200 (+33%)
Combined impact:
- All 3 levers improved → CLV €900 → €1,680 (+87%)
CLV:CAC Ratio (Critical)
Formula:
CLV:CAC Ratio = Customer Lifetime Value / Customer Acquisition Cost
Benchmarks:
- < 1: Losing money (insustainable)
- 1-2: Barely profitable
- 3: Good (industry standard)
- 5+: Excellent
Example:
- CLV: €900
- CAC: €200 (ads + marketing costs pentru a acquisi 1 client)
- Ratio: 4.5 → Healthy business
7. Attribution Modeling: Care Canale Funcționează?
Problema Attribution
User journey typical:
Day 1: Google Organic Search (product research) → leaves
Day 3: Facebook Ad (retargeting) → adds to cart → leaves
Day 5: Email (abandoned cart) → clicks → leaves
Day 7: Direct (comes back directly) → purchases
Question: Care canal primește credit?
- Last-click attribution: Direct (100%)
- First-click attribution: Organic Search (100%)
- Linear attribution: 25% fiecare
- Data-driven attribution: ML determines optimal (40% Organic, 30% Email, 20% Facebook, 10% Direct)
GA4 Attribution Reports
Location:
Reports → Advertising → Conversion Paths
Insights:
- Assisted conversions: Câte conversii a "ajutat" fiecare canal (chiar dacă nu e last-click)
- Multi-channel funnels: Paths populare (Organic → Paid → Email → Direct)
Action:
- Don't kill channels cu low last-click attribution - s-ar putea fie critical în early-funnel
- Budget allocation based on true contribution
Attribution Models în GA4
Model comparison:
Model Google Ads Facebook Organic Email Direct
────────────────────────────────────────────────────────────────────
Last-click €5,000 €2,000 €8,000 €1,000 €10,000
First-click €12,000 €3,000 €7,000 €500 €2,000
Linear €7,000 €4,000 €8,000 €3,000 €4,000
Data-driven €9,000 €5,000 €9,000 €2,000 €2,000
Insight: Google Ads undervalued în last-click (€5k) dar data-driven shows real value (€9k) → Don't reduce Google Ads budget!
8. Tools Ecosystem: Beyond GA4
Heatmaps & Session Recordings
Tools: Hotjar, Microsoft Clarity (free!), Crazy Egg
Insights:
- Heatmaps: Unde dau click users? Scroll depth?
- Session recordings: Urmărește actual user behavior
- Discovering bugs (e.g., checkout button not clickable pe mobil)
