PPC stands for Pay-per-Click, which is a model of online advertising where advertisers pay a fee each time one of their ads is clicked. This is a way for businesses to reach people who are searching for specific products or services online, and to get their website to appear in front of the right audience.

In PPC advertising, an advertiser creates ads and then bids on specific keywords that are relevant to their target audience. When a user performs a search using one of those keywords, the advertiser's ad may appear on the search engine results page (SERP) or on other websites that participate in the advertising network. If the user clicks on the ad, the advertiser is charged a fee.

PPC advertising is a popular way for businesses to drive traffic to their website and increase their online visibility, as it allows them to reach potential customers at the moment they are searching for what they offer. The cost of a PPC ad campaign can vary depending on a number of factors, such as the competition for the keywords being targeted, the cost-per-click bid set by the advertiser, and the relevance of the ad to the user.

There are many different platforms that offer PPC advertising, including Google Ads, Bing Ads, and Facebook Ads. Each platform has its own unique features and targeting options, so it is important for businesses to choose the platform that is right for their needs and goals.
