In any Google-search, Adwords appear on the right side of the screen or in a yellow highlighted box at the top, right before the search result. Yes, AdWords in Google are sponsored advertisements.

Each time a “Searcher” clicks on a company’s advertisement on Google, the company pays a specified sum of money (cost-per-click) – depending on the keywords it included in the ad.

Simply, this means that each word a company adds in its Google Ads has a price, and the company pays for the amount of clicks it gets. Last year, Google made $32.2 billion in advertising revenue. This represents about 97% of its total income.
