Paid Ads is online advertising that one pays for. Examples of paid advertising include Google Ads, Google Display, Facebook Ads, LinkedIn Ads, Instagram Ads, Twitter Ads, Pay-Per-Click (PPC), Programmatic Advertising, and more.
Paid ads are then presented to an audience that a marketer defines in the ad platform. And as the name suggests, you pay when someone clicks your ad. In addition to paying for each click, some advertisers set up their ads to pay per 1000 views (CPM), otherwise called impressions. Conversely, there are also organic/ free ads, especially in the social media.
