An ad that displays in a new browser window.
Pop up windows come in many different shapes and sizes, typically in a scaled-down browser window with only the Close, Minimize and Maximize commands.
There is a strong resentment by some Web surfers towards pop-up ads. Marketers often do not realize the ill-will generated by pop-ups because it is easier to click the “close” button than send an email to complain. What can often be seen is an above-average click-through rate, although some of this can come from “false positives,” unintentional clicks when the pop-up gets in the way of the desired target. Advertisers can get a better picture of the effectiveness of pop-up advertising by paying attention to conversion rates and return on investment (ROI).
