PPC, or Pay-Per-Click, 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 social media platforms, driving traffic to their websites. Advertisers bid on keywords relevant to their products or services, and ads appear in search results or on websites that match those keywords. The most common platform for PPC is Google Ads, where businesses can create targeted ads that appear when users search for specific terms. PPC campaigns can be highly effective, as they allow advertisers to reach potential customers actively searching for their offerings.
