Advertising platforms are online services that allow businesses to promote their products or services to a targeted audience. These platforms, such as Google Ads and Facebook Ads, provide tools for creating ads, selecting target demographics, and analyzing campaign performance. They help advertisers reach potential customers based on their interests, behaviors, and online activity. These platforms operate on various models, including pay-per-click (PPC) and cost-per-impression (CPM). Advertisers can set budgets and bid for ad placements, ensuring they only pay when users engage with their ads. This flexibility makes advertising platforms accessible for businesses of all sizes.
