Google Ads is a powerful advertising platform that allows businesses to display ads across Google's vast network, including search results, YouTube, and millions of websites through the Google Display Network. To show Google Ads on a website, publishers need to sign up for Google AdSense, which connects their site to advertisers using Google Ads. Once approved, website owners place ad code provided by AdSense into their site's HTML. Google then automatically displays relevant ads based on the website content and user behavior. This helps publishers earn money while advertisers reach their target audience more effectively through Google Ads.
