**From manual media buying to automated, data-driven advertising**
Digital advertising has changed dramatically over the last decade.
Brands are no longer dependent only on traditional advertising channels or manually purchasing individual advertising placements. Today, technology enables advertisers to make data-driven decisions and purchase digital advertising inventory automatically.
This technology-driven approach is known as **Programmatic Advertising**.
For anyone looking to build a career in digital marketing, AdTech, media buying, or performance marketing, understanding programmatic advertising is becoming increasingly valuable.
What Is Programmatic Advertising?
Programmatic Advertising is the automated buying and selling of digital advertising inventory using technology, data, and algorithms.
Instead of manually contacting publishers and negotiating every advertising placement, advertisers can use programmatic platforms to identify relevant advertising opportunities and participate in automated auctions.
The basic ecosystem looks like this:
**Advertiser → DSP → Ad Exchange → SSP → Publisher → Audience**
The entire process can happen extremely quickly when a user loads a webpage or app.
A Simple Example
Imagine that an automobile company wants to advertise a new SUV.
The company wants to reach people who are interested in automobiles and are located in specific cities.
Instead of showing the advertisement to everyone, the advertiser can use programmatic technology to identify relevant audiences and bid on suitable advertising opportunities.
If the impression matches the campaign's targeting requirements, the advertiser's platform can participate in the auction.
The winning advertisement is then displayed to the user.
This automated process helps advertisers make media-buying decisions based on campaign objectives and available data.
How Does Programmatic Advertising Work?
Let's simplify the process.
Step 1: A User Visits a Website
A user opens a webpage or application containing an available advertising placement.
Step 2: The Advertising Opportunity Is Sent to the Marketplace
The publisher's technology makes the available impression available through its supply-side platform.
Step 3: Advertisers Evaluate the Impression
Demand-side platforms evaluate the opportunity based on campaign requirements.
Factors may include:
* Audience characteristics
* Location
* Device
* Context
* Campaign objectives
* Previous interactions
* Budget
* Bid strategy
Step 4: Advertisers Bid
If the impression is relevant, the advertiser's DSP can submit a bid.
Multiple advertisers may compete for the same impression.
Step 5: The Auction Determines the Winner
The programmatic marketplace determines which eligible bid wins according to the applicable auction and marketplace rules.
Step 6: The Advertisement Is Displayed
The winning creative is delivered to the advertising placement.
All of this can happen within a very short period.
## Understanding the Programmatic Ecosystem
To build a career in programmatic advertising, you need to understand the major components.
DSP — Demand-Side Platform
A **Demand-Side Platform** helps advertisers and agencies purchase digital advertising inventory programmatically.
DSPs can provide capabilities for:
* Campaign management
* Audience targeting
* Bidding
* Budget management
* Creative management
* Reporting
* Optimization
SSP — Supply-Side Platform
A **Supply-Side Platform** helps publishers manage and monetize their advertising inventory.
While the DSP represents the buying side, the SSP represents the selling side.
Ad Exchange
An ad exchange provides a marketplace connecting buyers and sellers of digital advertising inventory.
It facilitates the buying and selling process between demand and supply.
Why Do Companies Use Programmatic Advertising?
Programmatic advertising can provide advertisers with greater automation, scalability, targeting capabilities, and measurement.
Some important advantages include:
**Automation**
Reduce the need for manual media-buying processes.
**Targeting**
Reach audiences based on available targeting signals and campaign requirements.
**Scalability**
Manage campaigns across large volumes of digital inventory.
**Measurement**
Monitor campaign performance using advertising metrics.
**Optimization**
Use performance data to make campaign adjustments.
Important Programmatic Advertising Metrics
Anyone learning programmatic advertising should become comfortable with common digital advertising KPIs.
CPM
**Cost Per Thousand Impressions**
Used to understand the cost of delivering impressions.
CTR
**Click-Through Rate**
Measures the percentage of impressions that resulted in clicks.
CPC
**Cost Per Click**

### ROAS
