If you're new to online advertising, you have probably come across both Google Ads (formerly Google AdWords) and Google AdSense. The names are similar, but the two programs do opposite jobs. Google Ads is for advertisers who want to promote products or services to a specific audience. AdSense is for website owners who want to earn money by displaying ads on their sites.
In this guide we look at the main differences between the two, when each one makes sense, and what to watch out for if you plan to use both.
What Is Google Ads?
Google Ads helps businesses reach potential customers by placing ads in Google search results, on YouTube and across the Google Display Network. It works like an auction: advertisers bid on keywords and audiences, and ads are triggered when people search for terms related to the business or browse relevant content. Advertisers typically pay per click, per view or per thousand impressions, depending on the campaign type. The goal is to send qualified traffic to a website and turn it into leads and sales.
What Is Google AdSense?
Google AdSense lets website publishers monetize their content by displaying targeted ads on their pages. Google matches ads to the page content and to the visitor, so the ads are relevant to the audience. When visitors view or click those ads, the publisher earns a share of the revenue. Advertisers reach new audiences, publishers get paid for their space and Google runs the marketplace in between.
Google Ads vs Google AdSense at a Glance
| Google Ads | Google AdSense | | --- | --- | | For advertisers | For publishers (website owners) | | You pay Google to show your ads | Google pays you to show ads on your site | | A media-buying channel | An ad-sales channel | | Ads appear on Google Search, YouTube, Display Network and more | Ads appear on your own web pages | | You choose keywords, audiences, locations and devices | Google chooses which ads to show based on your content and visitors | | You set budgets and bidding strategies | You choose ad placements and formats | | Launched in October 2000 (as AdWords) | Launched in June 2003 |
Can You Use Google Ads and AdSense Together?
Yes, but with care. Some site owners buy traffic with Google Ads and hope to earn it back from AdSense clicks. This rarely works: what you pay per click as an advertiser is usually far more than what you earn per click as a publisher, so relying on that gap for income is not a viable strategy.
There are also policy risks. Google Ads expects landing pages to offer useful, original content. Pages that exist mainly to show ads to paid visitors can fall foul of Google Ads destination policies and put your accounts at risk. If you advertise a page, make sure it genuinely serves the people clicking your ad.
Ad placement matters too. Cramming too many ads above the fold hurts the user experience and often reduces clicks, so follow AdSense's placement policies and recommendations.
Do You Need Separate Accounts?
You can use the same Google login for both Google Ads and AdSense, but the accounts are completely independent. You could lose access to one while still having access to the other, so keep that in mind and have a backup plan for each.
When Should You Use AdSense?
AdSense suits websites with steady traffic and useful content, such as blogs, news sites and resource sites. Once it's set up, Google automatically fills your ad spaces with relevant ads from advertisers competing for that inventory, so you can earn revenue without selling ad space yourself. The more valuable your audience and content, the more advertisers will compete to appear on your pages.
When Should You Use Google Ads?
Google Ads lets businesses reach potential customers who are already searching for what they offer. By appearing at the top of the search results, advertisers can capture existing demand. Beyond search, display, video and other campaign types can also reach people in your target market while they browse, which helps build awareness and bring past visitors back.
What the Two Have in Common
Both platforms reward relevance. For advertisers, careful keyword research and well-matched landing pages lead to better results and lower costs. Long-tail keywords help you target your audience precisely without breaking the bank. For publishers, focused, high-quality content attracts more relevant ads and better-paying advertisers.
Which One Is Right for You?
The choice depends on which side of the marketplace you're on.
Your goals
If you want to sell a product or service, generate leads or grow traffic quickly, Google Ads is the tool for you. If you already have an audience and want to earn from it, AdSense is the one to consider.
Your budget
Google Ads costs money: you set a budget and pay for the clicks, views or impressions you receive. AdSense costs nothing to join, but it only pays meaningfully once your site attracts a decent amount of traffic.
Your type of business
Think about what you offer, who your customers are and how they buy. A local service business or online store will usually get more value from advertising, while a content publisher will usually benefit from monetization.
Key Differences Between Google Ads and AdSense
Setup
Setting up a Google Ads account takes a few minutes, with no contracts or commitments. You sign in with a Google account, add billing details and build your first campaign.
For AdSense, you add your site's URL and your payment and contact details, then place the AdSense code on your site. Google reviews the site before ads can be shown. After that you can choose where and which kinds of ads appear, or let Auto ads handle placement for you.
Who pays whom
With Google Ads, you invest in a campaign and pay Google from your budget. With AdSense, you offer your website's space to Google so it can display relevant ads, and you receive a share of the revenue those ads generate.
Who it's for
AdSense is for website publishers, bloggers and other content creators who want to monetize their sites. Google Ads is for businesses that want to advertise within Google's network in a way tailored to their needs.
Competitiveness
In Google Ads, competition determines what you pay: crowded industries usually mean higher click prices. In AdSense, competition works in your favor, because more advertisers bidding for your audience can mean higher earnings.
Ad formats
AdSense offers display, in-feed, in-article and multiplex ads, plus Auto ads that place ads for you. Google Ads offers a much wider range of campaign types, including Search, Display, Video, Shopping, Performance Max, Demand Gen and App campaigns.
Targeting
Google Ads gives advertisers detailed targeting: keywords, locations, languages, devices, audiences and remarketing to people who have already interacted with your website. AdSense publishers don't target anyone. Instead, they can block certain ad categories or advertisers they don't want on their site.
Pricing and bidding
Advertisers can choose from several bidding strategies, such as manual CPC, Maximize clicks, Maximize conversions, Target CPA and Target ROAS, or pay per impression on some campaign types. Publishers have no say in this. They earn according to how advertisers buy the inventory on their pages.
Ad design
Advertisers control the creative: headlines, descriptions, images, logos and videos. AdSense publishers can't change the content of the ads, but they can control which formats appear, where they appear and, for some formats, their style.
History
Google AdWords launched in 2000 and was renamed Google Ads in 2018. AdSense, Google's contextual advertising program for publishers, followed in 2003.
The Bottom Line
Google Ads is for growth: you pay to put your business in front of potential customers. Google AdSense is for monetization: you get paid to show other businesses' ads to your audience. Understanding what each platform is for, and the rules that apply when you use both, will help you pick the right one for your situation.
