  1. Online advertising (en-US)

    Online advertising is the use of digital channels to promote products, services, or ideas to specific audiences. It typically appears on websites, mobile apps, search engine results, social media platforms, streaming services, and email. Advertisers choose targeting methods such as keywords, user interests, location, device type, or past behavior, then pay based on models like impressions (CPM), clicks (CPC), or actions (CPA).

  2. How it works

    Most online advertising relies on ad platforms and automated systems that match ads to users in real time. Campaigns are managed through dashboards where advertisers set goals (e.g., traffic, leads, sales), budgets, and creative assets (text, images, video). Measurement is done using analytics and tracking tools to estimate reach, engagement, conversions, and return on investment. Privacy practices and consent requirements can affect what data is available for targeting and measurement.

  3. Common types

    Common formats include search ads, display banner ads, video ads, social media ads, sponsored content, retargeting ads, and email marketing. Many campaigns use landing pages to guide users toward a desired action, and they may run A/B tests to improve performance.
