Ads are media displayed on a site to alert visitors of products or services that may be of interest to them.
Ads, or advertisements, are media displayed to visitors of a website. The purpose of the ad is to inform visitors of products or services they may be interested in.
Ads may refer to photos, videos, animations, audio clips, or text which prompts a user toward an action: such as purchasing a product, visiting a specific page or website, or calling a phone number. The ad may be for internal use (direct traffic to a particularly important part of one's one website), or external (direct traffic to another website).
In the case of external ads, third party integration is often involved, such as Bing Ads or Google Adsense. This type of arrangement is symbiotic between the website owner (who usually received monetary compensation for successful conversion or exposure), the company hosting the ad service (who receives a cut of the action), and the party that has purchased an advertisement (who hopes to receive an increase in traffic or sales conversions).
