GOOGLE :-

Google’s primary revenue generator is a pair of advertising services known as Ads and AdSense. Advertisers use Ads to submit advertisements to Google that include a list of keywords related to a product, service, or business. When a Google user searches for one or more of those keywords, the ad appears in a sidebar on the SERP. Every time a user clicks on the ad and is directed to the advertiser’s website, the advertiser pays Google.
