The easiest way to describe this concept is simply using the internet to tell people about a product or a service. In the past, businesses used big billboards on the road or short clips on television to get attention from the public. Today, those same businesses use websites, social media apps, and search engines to find the exact people who might want to buy from them. It is just a modern way of connecting sellers with buyers through digital screens. Does this explanation make the concept easy for a complete stranger to understand?
