Google Ad Manager
Google DFP enables the publishers to manage their ad inventory in a more effective way by offering an intuitive set of features. Let's dive deep into what they are.

Did you know 81% of small publishers are using Google Ad Manager to monetize their ad inventories? Whether you knew it or not, the statistic must have astounded you. The market share of Google Ad Manager proves how it is leading in the advertising industry. 

However, due to the existence of several Google’s publishing products, it happens to be quite difficult for beginners to understand the difference. And how each product works. If you are also in the same boat, this article is catered to you. Here we are going to discuss everything related to Google Ad Manager from the basics to how to set it up and start serving ads. So, shall we start?

Table of Contents:

What is Google Ad Manager?

In short, Google Ad Manager is an ad server. But what’s an ad server? It is a technology that enables the publishers to define, manage, and monitor ad inventories on their web, mobile app, or video ad inventories in order to display various types of ads.

Being an ad server, Google Ad Manager behaves as the central place that manages all direct advertisers, indirect advertisers, ad networks, ad exchanges, and other ad-tech partners. It enables the publishers to:

  • Display ads on the website including direct-sold ads, programmatic ads, and house (publisher’s in-house products/services) ads.
  • Control the ads and define rules to determine where the ads will be displayed on the pages.
  • Monitors and tracks the performance of ads.

Versions of Google Ad Manager

There are two types of Google Ad Manager accounts – Google Ad Manager for Small Business and Google Ad Manager 360. Let’s have a quick overview of both types.

Google Ad Manager for Small Business

Google Ad Manager for Small Business is a free version of Ad Manager, and it is designed for small to medium-sized publishers. With this version, you can have:

  • 90 million monthly display ad impressions to 200 million monthly display ad impressions based on the country*, and
  • 800,000 monthly video ad impressions monthly.

In addition to the ad serving, it provides various decent features including reporting and access to API.

However, these features are limited since it is a free version and designed for publishers with a few million impressions. To use advanced features and serve the ad impressions more than the threshold, a publisher has to upgrade to Google Ad Manager 360.

Google Ad Manager 360

Google Ad Manager 360 is the premium or paid version of Ad Manager and provides access to features including advanced reporting, video solutions (hosted video size limit, interactive ad formats, etc.), audience solutions for better segmentation, and so on. Not only this, but you can also get direct access to Google support, integrate Google’s Data Studio for better reporting, and more.

Basic Terminologies Involved in Google Ad Manager

  • Inventory: The ad units available for you to sell is called as an inventory. These can be grouped into various categories.
  • Tags: Tags are the HTML and JavaScript codes that are placed on your website for the purpose of linking ad units to your inventory.
  • Placement: The pattern of various ad units.
  • Trafficking: Ad trafficking is the process of creating and managing ad campaigns. You can create inventory by targeting a specific audience.
  • Ad unit: Ad Units are the places on a web page where an ad or group of ads can appear.
  • Forecasting: Depending on the website impressions, Forecasting calculates the amount of ad inventory needed in the future. It prevents the overselling of inventories.
  • Reporting: The process of analyzing the ad data to see the performance of every ad is called Reporting. These reports are customizable and enable you to create a more effective ad campaign.

How does Google Ad Manager Work?

As Google Ad Manager is an ad server, publishers are using it to manage their direct and indirect advertisers. At a basic level, the Ad Manager works as described below:

  1. A publisher defines the ad inventories (or ad units) in the ad server. There are a variety of ad units’ sizes available in Google Ad Manager
  2. While defining, he/she can generate the ad tags that need to be added to the page’s source code. These ad tags are snippets of HTML or JavaScript code.
  3. Publisher creates line items* and orders that are basically ad campaigns and represent the type of advertisers.
  4. When the user visits a web page, the ad tag sends a request to return an ad from Google Ad Manager.
  5. Ad Manager finds the right advertisers (or you can say line items) according to the details sent via the ad request and displays the ad on the specified inventory.

*A line item is the primary element in Google Ad Manager that helps the ad server to decide which ad to serve, how to serve and when to serve it. Here’s a complete guide that you can refer to understand everything about line items.

How is Google AdSense different from Google Ad Manager?

Although Google AdSense and Ad Manager enable the publishers to sell ads on their websites, each of them offers different kinds of features and services. AdSense is an ad network that helps publishers to sell their bulk of ad inventories to Google Ads advertisers. 

Whereas Google Ad Manager is an ad server that allows you to sell your ad inventories to Google advertisers as well as non-Google advertisers. Because Adsense is an ad network, you cannot connect with other ad networks to monetize your ad inventories. However, with Google Ad Manager, you can.

Moreover, there are various other differences between Google Ad Manager and Google AdSense that we have outlined here.

Can you use AdSense with Google Ad Manager?

Of course. In fact, it is recommended to publishers to use Google AdSense along with Ad Manager in order to maximize the ad revenue. How does it increase revenue?

Selling all of the ad inventories is essential to reach the potential revenue. However, many publishers cannot sell all ad inventories every time. In such situations, Google AdSense helps to sell the unsold ad inventories to its Google advertisers. Serving a Google ad is definitely better than leaving the ad inventory remnant, right?

You can run multiple other ad networks along with Google AdSense to increase the yield further. But make sure that other ad networks are compatible with AdSense. Here’s a detailed guide on how to run multiple ad networks in Google Ad Manager.

When do you need Google Ad Manager?

Getting more than 500,000 monthly visitors on your website? It’s high time to sign-up for Google Ad Manager. Google Ad Manager would be needed if:

  • You want to manage both direct and programmatic advertising campaigns at one place,
  • You want to take advantage of Google’s marketplace Ad Exchange, and
  • You want to run multiple ad networks/SSPs/exchange*s to increase the demand for your ad inventories. 

*SSPs and Ad exchanges are the middlemen that connect you to the advertisers. Unlike Google AdSense or any other ad network, SSPs and Ad Exchanges can offer you to sell your ad inventories to multiple advertisers in real-time and at higher eCPM rates.

Is Google Ad Manager an Ad Server or an SSP?

Basically, both. As Google says “Not just an ad server or sell-side platform (SSP)”, Google Ad Manager is a complete platform that can act as an ad server as well as an SSP. How does it behave like an SSP? Since Google integrated its Ad Exchange into Ad Manager, Google Ad Manager enables the publishers to bring additional demand via AdX.

Organizing your Ad Partners in Google Ad Manager

If you already have an ad partner with you, it’s quite simple to organize them in Google Ad Manager. Some best practices to Organize your Ad partners are as follows:

  1. Each advertiser should be created under a separate order number. This will simplify your reporting.
  2. Maintain a considerate hierarchy of orders and campaigns.
  3. Always use passbacks so that your unfilled inventories get filled by the house line items or any other passback network by GAM. Thus, there is no impression left unattended. (Hint: You can also use ‘Header Bidding‘ which increases your revenue and eliminates the need for any passbacks).
