Pay Per Click (PPC) is an online advertising model where advertisers pay a fee each time their ad is clicked. This method allows businesses to gain visibility on search engines and websites, driving traffic to their sites. Advertisers bid on keywords relevant to their products or services, and ads appear in search results or on partner sites. PPC campaigns can be highly targeted, allowing advertisers to reach specific audiences based on demographics, interests, and behaviors. Platforms like Google Ads and Facebook Ads are popular for managing PPC campaigns, providing tools to track performance and optimize ad spending effectively.
