Key Topics Covered

Understanding Programmatic Buying

Programmatic buying is the automated process of purchasing digital advertising that targets the right user, at the right time, on the right device, with the right message. Unlike traditional media buying where you call publishers individually and negotiate placements, programmatic advertising uses technology platforms to automate the entire process.

The Evolution from Traditional to Programmatic

Traditional Digital Buying (Pre-Programmatic):

  • Called individual publishers (Onet, WP, TVN24)
  • Negotiated placements manually
  • Signed individual insertion orders
  • Managed invoices separately for each publisher
  • Limited transparency and control

Affiliate Networks Era:

  • Aggregators representing multiple publishers
  • Simplified buying but reduced transparency
  • Issues with brand safety and ad fraud
  • Rising CPMs without clear value

Programmatic Revolution:

  • Single platform managing thousands of publishers
  • Real-time bidding and optimization
  • Complete transparency into where ads appear
  • Advanced targeting using first-party and third-party data
  • Automated campaign management at scale

Demand-Side Platforms (DSPs) Explained

DSP (Demand-Side Platform) is the technology that advertisers and agencies use to buy digital advertising programmatically. The major platforms discussed:

Google Display & Video 360 (DV360):

  • Enterprise-grade programmatic platform
  • Access to Google Display Network plus external exchanges
  • Advanced targeting and optimization capabilities
  • Integrated with Google Marketing Platform

The Trade Desk:

  • Independent DSP with global reach
  • Access to premium inventory and data partnerships
  • Advanced attribution and measurement tools

Amazon DSP:

  • Access to Amazon’s first-party shopping data
  • Premium placements on Amazon properties
  • Retail media network integration

Other Major DSPs:

  • Adform
  • Xandr
  • And approximately 100 ad exchanges globally

The Four Types of Programmatic Deals

1. Open Auction (Open Market)

What it is: Public marketplace where any advertiser can bid on available inventory

How it works:

  • Lowest priority in the waterfall
  • Real-time bidding against all other advertisers
  • Access to Google Display Network and other open exchanges
  • No guaranteed impressions or pricing

Best for:

  • Performance campaigns seeking scale
  • Finding users across the entire web
  • E-commerce and direct response advertising
  • Budget-conscious campaigns

Example scenario: E-commerce company selling office supplies wants to retarget users who browsed their website across thousands of publisher sites

2. Private Auction (Private Marketplace)

What it is: Invitation-only auction with selected advertisers

How it works:

  • You must be invited by the publisher
  • Bid against other invited advertisers only
  • Higher priority than open auction
  • No guaranteed impressions
  • Competitive bidding determines winner

Best for:

  • Premium inventory access with flexibility
  • Campaigns requiring optimization and price discovery
  • Advertisers wanting quality placements with bidding control

Think of it like: An exclusive art auction where only select collectors receive invitations, and they bid against each other for premium pieces

3. Preferred Deal (Fixed Price Deal)

What it is: Pre-negotiated fixed-price access to inventory

How it works:

  • Fixed CPM negotiated in advance
  • First look at inventory before it goes to auction
  • No impression guarantees
  • You buy at the agreed price if inventory matches your targeting

Best for:

  • Budget predictability and control
  • Safe testing for teams new to programmatic
  • Campaigns with strict cost parameters
  • Multi-campaign management requiring stable pricing

Key advantage: Protection against overbidding – even if someone sets the wrong bid by adding extra zeros, you only pay the negotiated rate

Example scenario: Large advertiser managing 50 campaigns simultaneously wants cost certainty across all markets

4. Programmatic Guaranteed (PG)

What it is: Guaranteed delivery deal with fixed pricing and impressions

How it works:

  • Highest priority in the waterfall
  • Guaranteed number of impressions
  • Fixed CPM and delivery timeframe
  • Reserved inventory exclusively for you

Best for:

  • High-visibility brand campaigns
  • Executive/stakeholder visibility requirements
  • Product launches requiring guaranteed reach
  • Campaigns where delivery certainty matters most

Example scenario: CMO wants to ensure the company’s new product appears on the homepage of major news sites during launch week

Deal Priority Waterfall

Understanding how programmatic deals prioritize (from highest to lowest):

  1. Programmatic Guaranteed – Gets first access to inventory
  2. Preferred Deal – Second priority with fixed pricing
  3. Private Auction – Invited bidders compete
  4. Open Auction – Everything remaining goes to open market

Important note: Some publishers reserve premium placements (like homepage top banners) exclusively for PG or Preferred Deals and never release them to open auction.

DSP vs. Google Ads: When to Use Each Platform

Use Google Ads When:

✓ Small to medium budgets (under €5M annually)
✓ Simple targeting requirements
✓ Limited team resources
✓ Only need access to Google Display Network
✓ Single-market campaigns

Use DSPs (Programmatic) When:

✓ Larger budgets justifying technology fees
✓ Need access beyond Google’s ecosystem
✓ Require advanced targeting granularity
✓ Want complete campaign transparency
✓ Managing multi-market operations
✓ Need direct publisher relationships
✓ Require detailed performance reporting
✓ Building in-house media capabilities

Technology costs: DSPs charge platform fees (typically percentage of spend or monthly fee), so budget size must justify this additional cost.

Understanding the Programmatic Ecosystem

Advertiser Side (Buy-Side):

Trading Desk → DSP → Ad Exchange → SSP → Publisher

  • Trading Desk: Team managing campaigns
  • DSP: Technology platform for buying ads
  • Ad Exchange: Virtual marketplace connecting buyers and sellers

Publisher Side (Sell-Side):

Publisher → SSP → Ad Exchange → DSP → Advertiser

  • SSP (Supply-Side Platform): Technology publishers use to sell inventory
  • Ad Server: Delivers and tracks ad impressions
  • Header Bidding: Simultaneous auction across multiple demand sources

The Real-Time Bidding Process (Happens in 0.04 Milliseconds):

  1. User visits publisher website and accepts cookies
  2. SSP sends bid request to ad exchanges with user data
  3. DSPs receive bid request and evaluate against campaign targeting
  4. DSPs submit bids based on user value
  5. Highest bid wins
  6. Winning ad creative serves to user
  7. Impression tracking and attribution recorded

What data is passed:

  • User browsing behavior
  • Previous site visits
  • Search history (with consent)
  • Device information
  • Geographic location
  • Demographic signals
  • Interest categories
  • Purchase intent signals

Programmatic Deal Scenarios: Which to Choose?

Scenario 1: Brand Awareness – CEO Wants Visibility

Situation: New product launch. CEO/CMO wants to see the company’s ads on major news sites like TVN24.

Solution: Programmatic Guaranteed

Why:

  • Guarantees delivery and visibility
  • Can target specific IP addresses (executive’s office)
  • Ensures premium placement on high-profile sites
  • No risk of missing delivery targets
  • Complete control over when and where ads appear

Setup:

  • Negotiate PG deal with premium publishers
  • Reserve homepage placements
  • Set specific dayparting for peak visibility
  • Include frequency caps for target executives
  • Confirm delivery with publisher before campaign starts

Scenario 2: E-commerce Performance Campaign

Situation: Online retailer selling office supplies wants to drive sales with best possible ROI.

Solution: Open Auction

Why:

  • Access to maximum scale across thousands of sites
  • Find users wherever they are online
  • Dynamic pricing based on user value
  • Real-time optimization for conversions
  • No commitment to specific publishers

Setup:

  • Retargeting website visitors
  • Prospecting using lookalike audiences
  • Bid optimization for target ROAS
  • Exclude poor-performing placements
  • Focus on conversion metrics, not publisher prestige

Scenario 3: Multi-Brand Corporate Campaign Management

Situation: Large corporation managing campaigns for 10 brands across 15 European markets with strict budget controls.

Solution: Preferred Deals

Why:

  • Fixed pricing prevents overbidding accidents
  • Predictable costs for budget planning
  • Access to quality inventory without price fluctuations
  • Safe for teams with varying skill levels
  • Stable performance reporting

Setup:

  • Negotiate preferred deals with major publishers
  • Create templates for quick campaign deployment
  • Train teams on fixed-price deal mechanics
  • Set naming conventions for tracking
  • Build centralized reporting dashboard

Supply-Side Platform (SSP) and Publisher Monetization

How Publishers Sell Inventory

SSP Configuration:

  • Define which ad placements are available programmatically
  • Set minimum CPM floors
  • Create deal types (open, private, preferred, PG)
  • Configure brand safety rules
  • Set up header bidding partners

Monetization Strategies

Waterfall (Legacy):

  • Sequential requests to demand sources
  • First source gets priority, then next if they pass
  • Inefficient – doesn’t maximize revenue
  • Lacks transparency

Header Bidding (Modern):

  • Simultaneous requests to all demand sources
  • Real-time competitive auction
  • Maximizes publisher revenue
  • Better for advertisers (fair competition)

The Google Exception:

  • Google historically didn’t participate in header bidding
  • Publishers had to run separate auction
  • Led to creative workarounds
  • Dynamic continues to evolve

First-Party Data and Cookie Consent

Why Cookie Consent Matters

When users accept cookies on a publisher’s site, they enable:

  • Behavioral tracking across websites
  • Retargeting capabilities for advertisers
  • Audience segmentation based on interests
  • Attribution connecting ads to conversions
  • Personalization of ad messaging

The User Journey

1. User searches “microphones reviews” on Google
2. Visits YouTube to watch microphone comparison videos
3. Browses several audio equipment websites
4. Visits major news site and accepts cookie consent
5. SSP collects all this behavioral data
6. Passes it to ad exchange with bid request
7. DSP recognizes high-value audio equipment buyer
8. Microphone retailer bids $10 CPM for this user
9. User sees personalized microphone ad

All happens in 0.04 milliseconds

❌ Ignoring brand safety – Ads appearing next to inappropriate content

❌ Poor campaign structure – Lack of proper naming conventions and organization

❌ Over-targeting – Too many targeting layers limit scale

❌ Not using verification tools – Paying for invalid traffic and bot impressions

❌ Expecting instant results – Programmatic requires optimization time

❌ Ignoring creative quality – Even perfect targeting fails with poor creative
