FAQ

What is the difference between AdTech and MarTech?

AdTech generally refers to the software and platforms used to buy, sell, deliver, and measure digital advertising, such as ad servers, demand-side platforms, and ad exchanges. MarTech, or marketing technology, is broader and includes tools for email marketing, customer relationship management, analytics, personalization, and content management that support the entire customer journey, not just paid media. In practice the two stacks often overlap and integrate, but AdTech is primarily media- and inventory-focused while MarTech is customer- and lifecycle-focused.

How does programmatic advertising actually work in AdTech?

Programmatic advertising uses automated software to buy and sell ad inventory in real time. When a user loads a page or app, a signal is sent to an ad exchange, which holds an auction among demand-side platforms that represent advertisers. These platforms evaluate the impression using data such as context, device, and audience segments, place bids in milliseconds, and the winning ad is then served to the user. This process replaces many manual negotiations and allows for highly targeted, scalable media buying.

What is the role of cookies in AdTech, and what happens as third‑party cookies disappear?

In AdTech, third‑party cookies have been used to recognize users across sites, build audience segments, cap ad frequency, and attribute conversions. As major browsers phase out third‑party cookies, the industry is shifting toward first‑party data, contextual targeting, privacy-preserving identifiers, and clean rooms. Advertisers are investing more in direct relationships with publishers and in measurement methods that rely on aggregated or modeled data rather than individual-level tracking.

How do GDPR and similar privacy laws affect AdTech practices worldwide?

Regulations such as the EU’s GDPR and California’s CCPA/CPRA restrict how personal data can be collected, used, and shared for advertising. AdTech companies must provide transparency about data uses, obtain valid consent or rely on defined legal bases, honor user rights like access and deletion, and ensure appropriate safeguards when sharing data with partners. These rules have pushed the industry toward consent management platforms, data minimization, and greater accountability across the advertising supply chain.

What is ad fraud in digital advertising, and how can AdTech help reduce it?

Ad fraud involves practices that generate illegitimate ad impressions, clicks, or conversions, such as bots, fake sites, domain spoofing, and invalid traffic. It wastes ad spend and can distort performance metrics. Modern AdTech combats fraud with tools that verify viewability, detect invalid traffic patterns, authenticate inventory through initiatives like ads.txt and app-ads.txt, and use machine learning to flag suspicious activity. Working with verified vendors and maintaining transparent supply paths are key mitigation strategies.

How is artificial intelligence changing the AdTech industry?

Artificial intelligence in AdTech powers tasks such as bid optimization, dynamic creative, audience modeling, and budget allocation. Machine learning systems can analyze large volumes of performance and behavioral data to predict which impressions are most likely to drive a desired outcome and adjust bids or creative variants in real time. AI is also being used for brand safety classification, fraud detection, and forecasting, which helps advertisers run more efficient and responsive campaigns.

Why has connected TV (CTV) become such an important part of AdTech?

Connected TV combines the reach of traditional television with the targeting and measurement capabilities of digital advertising. Through CTV and over-the-top (OTT) platforms, AdTech systems can serve ads to specific audiences using data such as geography, interests, or household characteristics and can report on impressions and outcomes more precisely than linear TV. As streaming viewership grows globally, advertisers are increasingly shifting budgets into CTV inventory bought and managed through programmatic platforms.
