  1. What is the pixel dimension of the IAB's standard 'Medium Rectangle' ad unit?

    Answer: 300×250

    The Medium Rectangle (300×250 pixels) is one of the most widely used IAB standard ad units, commonly embedded within webpage content on both desktop and mobile.

  2. What does the IAB's LEAN acronym stand for in its ad principles?

    Answer: Light, Encrypted, Ad-Choices, Non-invasive

    LEAN stands for Light (small file size), Encrypted (served over HTTPS), Ad Choices (user control), and Non-invasive (respects user experience), forming the IAB's framework for better digital ads.

  3. What was the primary purpose of the IAB's 'New Ad Portfolio' introduced in 2017?

    Answer: To create flexible, aspect-ratio-based ad units that adapt across devices

    The IAB New Ad Portfolio introduced flexible 'fluid' ad units defined by aspect ratios rather than fixed pixel dimensions, enabling adaptability across varying screen sizes and devices.

  4. What is the standard pixel dimension of the IAB 'Billboard' ad unit?

    Answer: 970×250

    The IAB Billboard is a 970×250 pixel format, one of the larger standard display units designed for high-impact brand advertising across the top of a webpage.

  5. According to IAB guidelines, what does 'polite loading' mean for display ads?

    Answer: Ad sub-content loads only after the host page's main content has finished loading

    Polite loading delays the heavier sub-load portions of an ad from downloading until the host page has completed its initial content load, preventing ads from degrading page performance.

  6. What is the standard pixel dimension of the IAB 'Half Page' display ad unit?

    Answer: 300×600

    The IAB Half Page ad unit measures 300×600 pixels, also known as the 'large rectangle,' offering significantly more creative space than the standard 300×250 Medium Rectangle.

  7. What is the IAB's recommended maximum initial load file size for standard display ads?

    Answer: 200KB

    The IAB recommends a maximum initial load file size of 200KB for standard display ads to balance creative richness with acceptable page load performance for users.
