Everyone’s favourite rectangle, 300×250 is a highly versatile ad unit that still yields the highest interaction rate of all the IAB standard-compliant graphical ad units. It seamlessly blends in with page content and at the same time provides advertising space that is suitable for most rich media solutions. As such it is often the preferred base unit for ad formats that involve out-of-banner experiences:

  • Floating: attention-grabbing uninitiated overlay
  • Expandable: user-initiated overlay with substance

Generic Flash Example:

Video and Audio

Not available on Yahoo! Direct Response (Top 250) and VEVO.

A 30 second video can also play in this unit and must not loop. Video play can be uninitiated or user-initiated; however sound must be user-initiated and must have a one- second delay if it is initiated by roll-over of the mouse and also must be muted on roll-out. There must also be controls to pause video play and mute the sound.
