Definition - What does Online Advertisement mean?
An online advertisement is any promotional material that is optimized for and distributed via the internet.

Techopedia explains Online Advertisement
Most online ads are embedded in a web page's HTML or served to placeholders through an ad server. That said, there is a wide range of display and delivery options available for online advertisers who want their ads to stand out. Unfortunately, standing out doesn’t always get the results advertisers want. Excessive pop-ups and expanding box ads are certainly noticeable, but they are also intrusive, and can cause viewers to react negatively to the advertisers using them and the sites hosting them.
Done properly, online advertisements offer advertisers more control over how they reach consumers. Moreover, by tracking consumer behavior and their interaction with online advertisements, businesses can obtain valuable analytical data on what factors influence their customers' buying decisions.
