Google AdWords (now known as Google Ads) and Google AdSense are two of Google’s key advertising platforms. Both play a significant role in the online advertising ecosystem, but they serve different purposes and are designed for different users. Google Ads is a platform where advertisers create and run ads, while Google AdSense is a program that allows website owners or publishers to display ads on their sites and earn revenue. While they both deal with advertisements, their functions, goals, and users are distinct.
Definitions of Google Ads and Google AdSense
What is Google Ads (formerly Google AdWords)?
Google Ads, formerly known as Google AdWords, is an online advertising platform that allows businesses, marketers, and individuals to create and display ads across Google’s search engine results, its partner sites, and on platforms like YouTube and Gmail. Advertisers use Google Ads to promote their products or services and reach specific target audiences based on keywords, demographics, and online behavior. Google Ads operates on a pay-per-click (PPC) model, meaning advertisers pay only when a user clicks on their ad.
Key Characteristics of Google Ads:
- Advertiser-Oriented: Google Ads is designed for businesses and marketers who want to promote their products or services.
- Pay-Per-Click (PPC) Model: Advertisers pay when users click on their ads, making it a performance-based advertising system.
- Keyword Targeting: Ads are triggered based on specific keywords that users search for on Google.
- Ad Placements: Ads can appear on Google Search, the Google Display Network, YouTube, and other partner websites.
What is Google AdSense?
Google AdSense is a program that allows website owners or publishers to monetize their online content by displaying ads on their websites. AdSense provides a way for publishers to earn money when visitors view or interact with ads that are automatically placed on their websites by Google. These ads are usually text, image, or video ads that are relevant to the content of the website. Google AdSense uses a pay-per-click (PPC) or pay-per-impression (CPM) model, meaning publishers earn revenue when users click on the ads or when the ads are viewed.
Key Characteristics of Google AdSense:
- Publisher-Oriented: Google AdSense is designed for website owners, bloggers, and content creators who want to monetize their websites by displaying ads.
- Automated Ad Placement: Ads are automatically matched to the website’s content and visitor profile, ensuring relevance.
- Revenue Model: Publishers earn money either through clicks on the ads (PPC) or based on impressions (CPM), which is the number of times an ad is displayed.
- No Upfront Costs: Publishers do not pay to use AdSense, but rather earn revenue through the ads shown on their websites.

Google AdSense Revenue Models:
- Pay-Per-Click (PPC): Publishers earn revenue when visitors click on ads displayed on their websites. The amount earned per click varies depending on the advertiser’s bid and the relevance of the ad.
