DefinitionInternet advertising (インターネット広告) is the umbrella term for ads that are placed on or delivered through online media such as web pages, search results and email.
ExplanationCompared with TV or newspaper ads, it is easier to measure in numbers how often an ad was shown, how often it was clicked and how many purchases it led to. Many of its methods can also narrow down who sees the ad, based on users' attributes and behavior.
AnalogyJust as street signs, flyers and shop-front posters can all be lumped together as "street advertising," this is one name for every kind of ad that runs online.
