What is online advertising?

• A. Charging a company a fee to place an ad or text on your site.
• B. Email marketing to customers
• C. Displaying ads in television
• D. Developing a mobile app for users

Answer: (A)

Online advertising means earning revenue by selling space on your website or platform for advertisements. When a publisher has traffic, they can charge a company a fee to display an ad or sponsored text on that site, allowing the advertiser to reach the site’s audience. This is how ads appear as banners, text links, or other formats across web pages and apps. The other activities described are different: email marketing involves sending promotional messages to customers via email; displaying ads on television is traditional TV advertising; developing a mobile app is creating software for users to download and use, not placing ads on a site. So the clear idea of online advertising is selling ad space on your site for a fee.
