Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium, including a method for determining content visibility when a content item is included in a cross-domain iframe. The method includes determining a first estimate of a size of a webpage viewing area of a viewport associated with a browser including reading an outer bound for a size of the viewport. The method further includes determining a second estimate for a size of a content item for display in the webpage viewing area, including reading iframe inside measurements for the iframe from a browser. The method further includes determining content item visibility including determining a location of the content item relative to the webpage viewing area by reading a location of the viewport and the iframe in screen coordinates. The method further includes reporting the visibility.
