What Programmatic Advertising Actually Is
Programmatic advertising is the automated buying and selling of digital ad space.
Instead of negotiating directly with individual publishers, you use technology to bid for ad impressions across thousands of websites and apps in real time, often in the milliseconds it takes a page to load.
The result: your charity's ad can appear on news sites, blogs, apps, and digital platforms in front of precisely defined audiences, at scale, with a level of targeting and measurement that manual ad buying cannot match.
How the Technology Works
When someone visits a website that sells its ad space programmatically, an auction takes place in real time.
Advertisers who have defined their target audience profile bid for the opportunity to show that specific person an ad. The highest relevant bid wins, the ad is served, and the whole process takes milliseconds.
This is called Real-Time Bidding (RTB). The infrastructure behind it, Demand-Side Platforms (DSPs), Supply-Side Platforms (SSPs), and Data Management Platforms (DMPs), is complex.
For charities, the practical implication is straightforward: you can reach the right people across the open web without needing direct relationships with individual publishers.
The Targeting Power of Programmatic
Programmatic advertising offers several powerful targeting methods:
Audience targeting: Reach people based on their browsing behaviour, interests, and demographic data
Contextual targeting: Show ads alongside content related to your cause, a charity focused on mental health targeting articles about wellbeing
Retargeting: Reach people who have previously visited your website or engaged with your digital content
Geographic targeting: Focus spend on specific regions, cities, or even postcodes relevant to your work
Programmatic Formats
Programmatic can serve a wide range of ad formats:
Display banners: Image ads of various sizes across websites and apps
Native ads: Ads that match the look and feel of the surrounding content
Video: Pre-roll and mid-roll video ads on streaming platforms and video content sites
Digital out-of-home: Digital billboards and screens in public spaces, increasingly available programmatically
Connected TV: Ads served on smart TV platforms and streaming services
When Programmatic Makes Sense for Charities
Programmatic is not a starting point for most charities. It becomes relevant when:
You have exhausted the reach of search and paid social at your target audience
You are running a large-scale awareness campaign that requires broad reach
You need to retarget website visitors at scale beyond what social platform retargeting offers
You have a minimum budget to make the technology worthwhile (typically £2,000 or more per month)
For smaller charities, the Google Display Network offers a simplified entry point into programmatic-style advertising without the complexity of a full DSP.
Brand Safety and Quality Control
Programmatic's scale can be a liability if not managed carefully. Your charity's ad could appear next to harmful or inappropriate content without brand safety controls in place.
When working with programmatic, always specify brand safety categories to exclude (violence, adult content, misinformation), use allowlists of pre-approved publishers where possible, and review placement reports regularly.
10-Minute Exercise: Assess Your Readiness
Ask yourself three questions:
Is our charity already running search and paid social campaigns effectively?
Do we have a budget that would make programmatic viable?
Do we have the internal capacity or agency support to manage a programmatic campaign responsibly?
If the answer to all three is yes, programmatic is worth exploring. If not, focus on maximising the channels you already have before adding complexity.
Why is this important to know?
Programmatic advertising represents the future of digital media buying, and charities that understand how it works are better positioned to evaluate agency proposals, manage partnerships with media buyers, and eventually use the technology themselves.
Even if your charity is not ready to run programmatic campaigns today, understanding the ecosystem means you will not be left behind as the digital advertising landscape continues to evolve.
