Real-Time Bidding (RTB)

Apa Itu RTB?

RTB adalah metode programmatic dimana ad impressions dijual melalui real-time auction. Setiap ad impression dilelang secara individual dalam hitungan milidetik.

Jenis Auction

Second Price Auction (Traditional):

Bidder A: $5.00
Bidder B: $4.00
Bidder C: $3.00

Winner: Bidder A
Pays: $4.01 (second price + $0.01)

First Price Auction (Current Standard):

Bidder A: $5.00
Bidder B: $4.00
Bidder C: $3.00

Winner: Bidder A
Pays: $5.00 (what they bid)

Bid Shading

Dalam first price auction, DSP menggunakan bid shading:

• Algoritma yang mengurangi bid
• Mencegah overpaying
• Estimate what’s needed to win

AdSense vs Ad Manager

Targeting dalam Programmatic

Types of Targeting

1. Contextual Targeting

   • Based on page content
   • Keywords on page
   • Category of site

2. Behavioral Targeting

   • Based on user history
   • Sites visited
   • Past purchases

3. Demographic Targeting

   • Age
   • Gender
   • Income
   • Location

4. Device Targeting

   • Mobile vs desktop
   • OS
   • Browser

5. Retargeting

   • Cart abandoners
   • Past customers

Data Sources

First-Party Data:
- Publisher's own data
- User registration
- Site behavior

Second-Party Data:
- Partner's first-party data
- Data sharing agreements

Third-Party Data:
- Purchased from data providers
- Aggregated from multiple sources
- (Decreasing due to privacy)

Header Bidding

Apa Itu Header Bidding?

Header bidding adalah teknik yang memungkinkan publishers menawarkan inventory ke multiple ad exchanges secara simultan, sebelum calling ad server.

Traditional Waterfall vs Header Bidding

Waterfall (Sequential):

Ad Request → Exchange A (pass) → Exchange B (pass) → Exchange C (win)

Problems:
- Sequential = slower
- Miss higher bids from later exchanges
- Suboptimal revenue

Header Bidding (Simultaneous):

Ad Request → [Exchange A: $2.00]
           → [Exchange B: $2.50] ← Winner
           → [Exchange C: $1.80]

Benefits:
- All bids at once
- Best price wins
- Higher revenue

Header Bidding untuk AdSense Publishers

AdSense sendiri tidak support header bidding, tapi:

Option 1: Upgrade ke Ad Manager

• Untuk publishers besar
• Full header bidding support
• More control

Option 2: Open Bidding (Google’s solution)

• Available di Ad Manager
• Server-side bidding
• Less latency

Header Bidding Impact

Studies show header bidding can increase revenue:

• 10-50% lift untuk publishers
• More competition = higher CPMs
• Better fill rates

Privacy dan Future of Programmatic

Privacy Challenges

1. Third-party cookie deprecation

   • Chrome blocking 3P cookies (2025)
   • Safari already blocks
   • Firefox already blocks

2. Privacy regulations

   • GDPR (Europe)
   • CCPA (California)
   • Other regional laws

3. App Tracking Transparency (iOS)

   • Users opt-out of tracking
   • Limited IDFA access

Adaptations

Contextual Advertising Return:

Instead of: "Target user who visited car sites"
Now: "Target content about cars"

Benefits:
- No personal data needed
- Privacy compliant
- Still relevant

First-Party Data Focus:

Publishers with:
- User logins
- Email subscribers
- Direct relationships

Have advantage in:
- Audience targeting
- Data for advertisers
- Higher CPMs

Privacy Sandbox (Google):

New APIs replacing cookies:
- Topics API (interest-based)
- FLEDGE (retargeting)
- Attribution Reporting

Goal: Targeting without individual tracking
