Google has a plethora of products, such as Google AdSense, AdX, Ad Manager, AdMob, etc., which can quickly overwhelm publishers aiming to monetize and scale revenue via their site. Two such tools that mostly lead publishers to dilemmas are Google AdSense and Google AdX.
If you’re getting started with AdSense monetization or planning to scale AdSense revenue, understanding what sets these two products apart will help you to pivot to relevant channels at the right time to tap into potential opportunities.
This blog lists the similarities and differences between Google AdSense and AdX, who should use these products, eligibility criteria, etc., to help you choose the platform that can generate optimal revenue and opportunities for your site.
Google AdSense Overview
Google AdSense is an ad network designed for small to medium-sized publishers, bloggers, individual website owners, etc., to help them monetize site traffic by displaying ads. Publishers who comply with Google AdSense policies can run ads and earn revenue by leveraging their online visibility.
Eligibility Criteria to Opt-in for Google AdSense are:
- The user should be above 18 years old
- The site should have high-quality original content
- The site should attract legitimate traffic.
- The site should consistently follow Google AdSense policies and terms and conditions.
Comparatively, Google AdSense maintains a beginner-friendly environment where new or growing publishers can easily sign up, run ads, manage inventory and generate revenue without expert assistance. It is also compatible with desktop, mobile and H5 games, making it flexible for publishers to attract audiences across different modes without compromising user experience.
How does Google AdSense Work?
The mechanics behind Google AdSense are fairly simple. Publishers should add Google-assigned code to their site, allocate ad units to display ads, and select ad types, position sizes etc., to start running ads.

Once the ad inventory is available, Google matches ads relevant to the site and ad preferences. The ad inventory is sold to the highest bid placed on the ad units. Earlier, Google AdSense was led by a second-price auction model; however, the first-price bidding model has become a custom, where advertisers pay the highest bid price to win an ad inventory.
Google acts as an intermediary between publishers and advertisers, matching demand with existing advertising opportunities. Hence, publishers receive a standard 68% of revenue regardless of location. AdSense is also transitioning from CPC to a CPM payment model, allowing publishers to monetize the impression generated for the ads displayed on the site. CPM can potentially generate more consistent and higher revenue than CPC, especially if its ad placements have high viewability rates.
Google AdX Overview
Google AdX is an ad exchange platform that enables large publishers to connect with a vast network of premium advertisers in real time to tap into lucrative advertising opportunities and earn more revenue via ads. Powered by programmatic advertising, Google AdX offers multiple options for publishers to connect with relevant advertisers and gain more control over the ads displayed on their sites.
There are three types of auctions for publishers to reach advertisers:
1. Open Auction: Real-time bidding process where publishers open slots for all advertisers and maintain anonymity.
2. Private Auction: An invitation-only auction where select advertisers are given the opportunity to bid on premium ad inventory.
3. Preferred Deal: A direct deal between a publisher and advertiser with pre-negotiated pricing, offering the advertiser priority access to inventory before it enters the open auction.
The basic eligibility criteria to opt in for Google AdX include:
- 5 million page views and 10 million ad impressions per month
- Abide by geographical and language restrictions
- Content should not fall under sensitive categories
- You can also sign up with third-party Google MCM partners to access AdX if you don’t meet the first criteria. However, this will also be an invite-only opportunity. Your profile will be reviewed and validated before approval.
How Does Google AdX Work?
When a user visits a publisher’s site, the ad impression is sent to AdX, and an ad auction is conducted in real-time to sell ad units to the highest bid. AdX operates as a second-price auction where the highest bidder wins but pays the second-highest bid plus a small increment. If you’re using AdX via third parties, a standard fee percentage will be deducted from your revenue.
Google AdX connects publishers with multiple ad sources, such as ad networks, agencies, brands, demand-side platforms, etc., offering more opportunities than AdSense. Publishers also get advanced customization options, such as audience behaviors, location, preferences and more, to reach the ideal group of advertisers.
Unlike Google AdSense, AdX is accessed from the Ad Manager, and the onboarding process is comparatively complex. Once publishers make their ad inventory available on AdX, they can set floor prices (the price for the available ad units), specify which ads they want to allow and determine other parameters to control how their inventory is sold. Publishers get more control over ad preferences and choices in AdX.
While AdSense is fairly easy to manage with basic knowledge, AdX requires expert assistance to ensure optimal prices are set to meet potential advertisers at the same level. Setting high floor prices without a data-driven strategy can negatively impact performance. However, AdX is a profitable platform for publishers as they have multiple ways to reach advertisers who campaign high-quality ads.
