Google AdX and Google AdSense are the two main digital advertising platforms from Google for publishers. Both platforms enable website owners to monetize their traffic, so what’s the difference and what’s why are so many publishers switching?
Knowing which platform to use will save you time, development resources, and late-night headaches. Best of all, it will also help you increase your ad revenue.
In this guide, we’ll examine the differences between Google AdX and Google AdSense and show you which platform is the best fit for your website.
What Is Google AdX?
Google AdX (previously called DoubleClick Ad Exchange) is a marketplace where digital advertising space is bought and sold. As a programmatic advertising exchange, Google AdX uses real-time bidding (RTB) to determine the price of advertising space. It works like a stock exchange, where advertising space is openly traded.
For publishers, Google AdX is a marketplace where they can sell advertising space to a wide range of advertisers in real-time. Publishers retain control over which ads are shown on their websites and receive data on who purchased their inventory and for what price.
For advertisers, Google AdX provides a way to purchase ad space from publishers. Since a wide range of publishers uses the platform, AdX is an easy way to scale campaigns or target specific demographics of users. Advertisers also benefit from real-time bidding, which enables them to bid for ad space in real-time, depending on how much they value the impression.
Overall, AdX is an ad exchange that connects publishers and advertisers at scale, allowing both parties to more efficiently buy and sell display advertising space.
Is AdX owned by Google?
Google currently owns AdX. DoubleClick Ad Exchange was founded in 1995 and purchased by Google in 2008, when it was quickly rebranded as Google Ad Exchange (Google Ad Exchange or AdX for short). Microsoft and other companies raised concerns about the purchase as it was believed it would give Google too much control over online advertising. The Federal Trade Commission (FTC) and the European Union looked into the arrangement, and both gave the green light for the acquisition.
Is Google AdX A SSP?
Google AdX is widely regarded as one of the best SSPs in the market. As the world’s largest exchange of global inventory, AdX provides strong performance for publishers. Other popular SSPs include OpenX, Pubmatic, and Magnite. You can use header bidding to connect to these SSPs to increase your ad revenue.
What is AdX called now?
The programmatic buyers and networks formerly called “AdX buyers” are now known as “Authorized Buyers”. Google retired the AdX brand in 2018 when it integrated AdX into Google Ad Manager. The change was rolled out in the Ad Manager UI over several months.
What Is Google AdSense?
Google AdSense is an easy-to-use platform that enables website owners to monetize their content by serving ads. Website owners need only install a small piece of code on the site and select the spaces they want ads to appear.
Once AdSense is live, advertisers bid on the new ad space based on the website visitor’s profile. After an ad is served, AdSense bills the advertiser and pays the website owner per click or per impression. AdSense serves ads from advertisers who are using Google Ads, the Google Display Network, or other Google products.
AdSense helps reduce the manual input required from the publisher. Criteria such as ‘ad size’ and ‘ad placements’ can be automatically taken care of by using responsive ad units. In addition, the entry criteria for the platform are low. Publishers need to have family-friendly content, no invalid traffic, and no copyright complaints. As a result, AdSense is one of the most popular digital ad platforms for publishers – far more popular than AdX.
Google AdX vs Google AdSense: What Are the Key Differences?
The key differences between Google AdX and Google AdSense are:
- AdX delivers more ad revenue when optimized correctly for tier 1 Geos. With an optimized dynamic flooring setup, Google Open Bidding, and preferred deals, publishers can expect their ad revenue to increase between 20%-50% when switching from AdSense to AdX for tier 1 Geos
- AdSense is almost always best for tier 3 Geos. AdSense almost always outperforms AdX for tier 3 Geos.
- AdX has higher entry requirements than AdSense. With AdX, publishers need to have at least 5 million page views per month before they are eligible for consideration.
- AdSense is easy for non-technical publishers to use. To get the most out of AdX, you will need an AdX partner, advertising operations expert, and ad tech developer.
- AdX is accessed through Google Ad Manager. This is a separate platform from Google AdSense.
- AdSense has a low minimum payout. AdSense almost always outperforms AdX for tier 3 Geos. In addition, it has a $10 minimum for US-based publishers, making it ideal for websites with low traffic levels.
- AdSense can be automatically configured. While AdSense can automatically place ads on a website, AdX gives publishers more control over the way ads are sold and displayed. For example, publishers can’t set floor prices for impressions, and they can’t also sell ad space directly to advertisers.
Is AdX better than AdSense?
AdX provides more ad revenue than AdSense for tier 1 Geos, but other factors must be considered. In general, AdX is a good fit for larger websites with premium ad inventory. In comparison, AdSense is suitable for the long tail of smaller websites that don’t have a lot of resources to invest in their advertising technology stack.
How Do I Get Access to Google AdX?
You can access Google AdX directly in Google Ad Manager or through a Google MCM and AdX partner like Snigel. You’ll get maximum flexibility with direct access, but you’ll also need an advertising operations expert to maximize your ad revenue from the platform. When using a channel partner, you will need to share part of your revenue, but the channel partner will take care of the ongoing advertising operations work.
How To Access Google AdX Through A Channel Partner
It is easier to access Google AdX through a channel partner or network partner manager (NPM) like Snigel. You will need to meet the NPM’s minimum criteria to gain access. In general, a channel partner will want to see that your site has at least:
- 500k pageview per month
- 10% or more of your traffic coming from tier 1 countries
- Family-friendly content
- No invalid traffic
- A good history with Google AdSense or Google Ad Manager
How To Join Google AdX Directly
For direct access, you will need to first sign up for a Google Ad Manager (GAM) account and establish good scores for viewability, family-friendly content, and invalid traffic. After that, your Google account manager will be able to invite you to AdX at their discretion. You can ask your Google account manager to assess your suitability after your GAM account has been live for a few months. If you receive direct access, you will get the flexibility to manage your own AdX account. However, getting the most out of AdX is time-consuming.
The most successful AdX users constantly run tests and update their settings to take advantage of new features, pricing rules, technology, and ad formats. Overall, getting direct access makes sense if you have an ad operations expert and an ad tech developer on your team. For example, large publishers like Forbes and ESPN have these resources in-house. Otherwise, you’ll get more ad revenue and fewer headaches if you go through a Google channel partner.
What Are The Minimum Requirements For Google AdX?
To access Google AdX directly, you will need:
- A Google Ad Manager (GAM) account
- No history of policy violations, unsafe content, or invalid traffic
- An updated ads.txt file with details of all buyers
- At least 5 million pageviews per month
- A minimum of 10 million ad impressions per month for at least 6 months
It’s important to note that even if you meet these requirements, access to Google AdX is invite-only and at the discretion of your Google Account Manager. In addition, there may be further requirements from Ad Exchange with regard to content types and ad viewability.
How does Google Ad Exchange work?
What is Google Ad Manager?
Google Ad Manager is an ad management platform for large publishers who want granular control over their website setup. Ad Manager provides more functionality than AdSense and supports multiple ad exchanges and networks, including AdSense, Ad Exchange, third-party networks, and third-party exchanges. Here’s a detailed breakdown of the differences between AdManager and Ad Exchange.
Once you have gained access to Ad Exchange as a publisher, you will see a set of new features available in your Google Ad Manager account.
Google’s Ad review center provides features to help you find specific Ad Exchange ads to review and block. This can be helpful if you’re looking to monitor or improve your website’s ad quality. Google MCM partners like Snigel use the ad review center to continuously refine ad quality.
In an open auction, all advertisers connected to Ad Exchange can bid on the publisher’s ad inventory. This is also known as open exchange, real-time bidding (RTB) or open marketplace. It is the most traditional form of programmatic auctions. In an open auction, publishers can set a floor price for an ad but the final price is determined by how much advertisers are willing to bid. The inventory in this auction is not guaranteed.
Preferred deals allow publishers to offer inventory to specific advertisers before it goes to a private auction or open auction. Preferred deals can give buyers priority tier inventory, or be used to sell unique inventory. As such, this auction format is generally used to give premium advertisers the first option to buy inventory at a higher price than would be fetched through an open auction or private auction. Advertisers pay more in preferred deals because they get access to ad inventory that aligns with their brand or produces higher click-through and conversion rates.
Private Auctions allow you to invite a set of buyers to bid on a selection of your ad inventory via an auction. Here you specify a minimum CPM floor price, and that buyer must exceed the floor price to be eligible for the auction. The winner is determined using the same auction model that applies to the open auction.
What are the benefits of Google AdX?
Ad Exchange benefits for publishers:
- More ad revenue for the same ad space. Without AdX, many sellers have inventory that goes unsold or is sold for a price below its potential market value. AdX provides access to more premium advertisers which leads to better rates for ad inventory. The platform is most effective for tier 1 Geos while AdSense can outperform AdX for tier 3 Geos
- Access to more advertisers. While still being able to control who can advertise on the site
- Simplified reporting and payments. A single exchange manages it all
Ad Exchange benefits for advertisers:
- Get access to many more websites and more ad space. This means more options for your ad campaigns
- Use real-time bidding (RTB) technology. This allows advertisers to bid on ad space in real-time, depending on how much they value a particular ad impression
- More control. Decide where ads run and don’t run
Ad Exchange benefits for Google AdWords advertisers:
- Easy access to the websites in the Ad Exchange. In addition, advertisers can access all the existing websites in the Google Content Network through their AdWords interface.
Google AdX vs AdSense – which is better for your site?
If your website has less than 5 million page views per month, you will have no option but to go through an ad tech company since you do not meet the minimum criteria for a direct account. The good news is that ad tech companies are often able to offer additional services like header bidding and video ads that can further increase your ad revenue.
Alternatively, if you prefer to have an ad setup that is easy to maintain and doesn’t require working with a third party, you could stick with AdSense. While your ad revenue will be 10% – 40% lower with this option, you will still have access to text, image, or video ads. Overall, AdSense is a great fit for smaller independent publishers who are looking to focus on content creation rather than monetization.
