What Is Programmatic Advertising and Why UK Brands Are Adopting It

23 Mar What Is Programmatic Advertising and Why UK Brands Are Adopting It

What Is Programmatic Advertising?

Programmatic Advertising is the automated process of buying and selling digital ad inventory using software, algorithms, and real-time data. Instead of manually negotiating placements with publishers, advertisers use technology platforms to bid on impressions — all within milliseconds.

Three core components power the process:

• Demand-Side Platform (DSP): The tool advertisers use to set targeting parameters, budgets, and bids across thousands of websites and apps
• Supply-Side Platform (SSP): The tool publishers use to make their inventory available in automated auctions
• Ad Exchange: The marketplace connecting DSPs and SSPs through real-time bidding (RTB)

When a user loads a page, the ad exchange runs an auction. The DSP evaluates whether that user matches the advertiser’s target and places a bid. The highest bid wins, and the ad is served before the page finishes loading.
