Pay-per-click (PPC) is an online advertising model where advertisers pay a fee each time their ad is clicked. It's a way of buying visits to your site rather than attempting to "earn" those visits organically through search engine optimization (SEO) efforts. PPC is commonly associated with search engine advertising, but it also extends to social media platforms and display advertising networks. Here's how PPC typically works:

Ad Placement: Advertisers bid on specific keywords or phrases relevant to their target audience. When a user conducts a search using those keywords, the search engine displays relevant ads alongside the organic search results.

Ad Auction: Search engines like Google and Bing use an auction-based system to determine which ads to display and in what order. Factors such as bid amount, ad quality, and relevance to the user's search query influence ad placement.
