Abstract: Methods, systems, computer-readable media, and apparatuses for providing responsive advertisements are described herein. In some embodiments, a computing device may send a presentation including multiple advertisements to a user device. The computing device may receive an indication that an advertisement has been overlaid by a window and may, in response, determine to resize or relocation the advertisement. The computing device may determine impression credit for the advertisement based on a display duration for the advertisement prior to being overlaid by the window and a display duration for the resized or relocated advertisement while not being overlaid by any window.
