Adsense vs Adwords
Google ads(or AdWords) is a tool for advertisers who want to show their products or services to the world while Google Adsense is for publishers. The site which has Adsense integrated to it will be showing ads that are created on Google Ads by any company. This fall is the Google Display network. If any company uses Google Ads and create an ad this ad would be shown in a website which has integrated Adsense into it when a user clicks on that ad, Advertiser would have to pay to Google and some percentage is given to publisher(who is showing the ads).
