<p>A method, apparatus, system, article of manufacture and computer program product provide the ability to determine the opportunity to see an online advertisement. Determinations are made regarding whether the advertisement is in a visible portion of a webpage, whether the advertisement is in an active tab of a web browser, and whether a browser window is visible. A confirmation is conducted that the visibility of the advertisement is not hindered by an element or a parent element property. A percentage of the advertisement that has an opportunity to be seen is calculated by dynamically inserting visibility trackers into the advertisement and detecting which of the trackers are concurrently visible at a same time. Times each of the trackers are visible are calculated to determine a time in view measurement by ad percentage. A determination is made whether the advertisement is shown to a real, human, non-automated website visitor.</p> |
