Pay-Per-Click (PPC) is an online advertising model in which advertisers pay a fee each time one of their ads is clicked. It's a way to buy visits to a website rather than earning those visits organically through techniques like search engine optimization (SEO).

Here's how PPC typically works:

Ad Campaign Setup: Advertisers create ad campaigns using platforms like Google Ads (formerly known as Google AdWords), Bing Ads, Facebook Ads, and others. These campaigns involve selecting keywords or phrases relevant to their business.

Bid for Keywords: Advertisers bid on how much they are willing to pay for a click on their ad when a user searches for those keywords. The ad platforms often use an auction system to determine which ads appear when someone searches for a particular keyword.

Ad Creation: Advertisers create text or display ads that will appear when their chosen keywords are searched. These ads typically include a headline, description, and a link to the advertiser's website.

Ad Placement: When a user enters a search query matching the chosen keywords, the ad platform runs an auction to determine which ads are displayed and in what order. The order is based on factors like bid amount, ad quality, and relevance to the user's query.

Payment: Advertisers are only charged when a user clicks on their ad and is directed to their website. Hence the name "Pay-Per-Click." The cost of each click can vary widely depending on factors such as competition for keywords and the quality of the ad.
