An ad group is an essential part of a pay-per-click (PPC) campaign that organizes ads around a common theme. But to truly answer the question “What is an ad group?”, it’s necessary to think of it as a way to group a set of ads that share similar keywords and targeting settings. This organization allows for more precise control over which ads are shown to users when they search for specific terms.

Ad groups enable advertisers to target specific keywords with tailored ad copy, ensuring the right message reaches the right audience. For example, within a Google Ads campaign, each ad group will contain a set of keywords, ads, and a bid amount that together determine when and where your ads appear. The result is better click-through rates (CTR) and, ultimately, higher conversion rates.

Structure of an Ad Group

An ad group has several components working together to target the desired audience effectively. At the core, an ad group includes:

• Keywords: The specific words or phrases that trigger ads when searched by users. These keywords should be relevant to your products or services and aligned with the ad copy within the ad group.
• Ads: The actual advertisements that will be shown to users when their search queries match your selected keywords. Each ad group can have multiple ads, allowing for variations in messaging to be tested.
• Bidding Strategies: The approach you choose for how much you’re willing to pay for clicks or conversions. This can be set at the ad group level, giving you control over how much you invest in each group of keywords and ads.

Ad Group vs Campaign 

While both ad groups and campaigns are important to your PPC strategy, they serve different purposes. A campaign is an overarching structure that contains multiple ad groups. It defines the broader goals of your advertising efforts, such as budget, location targeting, and overall bid strategy. An ad group, on the other hand, is more granular. It focuses on specific themes within a campaign, organizing ads and keywords to target a more precise segment of your audience.

In essence, a campaign sets the stage for your advertising strategy, while ad groups execute the finer details of targeting and messaging within that strategy.

Ad Group Example

To clarify the difference, imagine you run an online store that sells various types of footwear, and you're setting up a Google Ads campaign (or in other PPC ad networks). You create a campaign called “Footwear Collection” to promote all types of shoes your store offers. This campaign might have an overall budget of $1,000, target customers in the United States, and use a bidding strategy focused on maximizing clicks.

Within the “Footwear Collection” campaign, you create specific ad groups for different types of shoes:

• The “Running Shoes” ad group might include keywords like “best running shoes,” “lightweight running shoes,” and “men's running shoes,” paired with ads that highlight the features and benefits of your running shoe selection. The bidding strategy in this ad group might be adjusted based on the competitiveness of the “running shoes” keywords.
• The “Dress Shoes” ad group would focus on keywords like “leather dress shoes,” “formal shoes,” and “women's dress shoes,” with ads tailored to customers searching for dress footwear.
• Similarly, the “Sandals” ad group would have ads and keywords specifically targeting customers looking for sandals.

Types of Groups in Ad 

Ad groups vary significantly depending on campaign goals and the types of ads running. Each type of ad group plays a distinct role in marketing campaigns, allowing advertisers to reach their audience across various channels and formats. Here are a few common types of ad groups based on different objectives and ad formats:

• Search Ad Groups: These groups are focused on targeting users through search engine queries. Keywords are matched to search terms, and relevant text ads are shown to users.
• Display Ad Groups: Used in display campaigns, these groups target users through visual ads on websites, apps, and videos. Instead of keywords, targeting might be based on audience demographics or interests.
• Shopping Ad Groups: Specific to e-commerce, these groups contain product ads that appear in search results with product images, prices, and descriptions.
• Video Ad Groups: These are tailored for video campaigns, particularly on platforms like YouTube, where video ads are shown to targeted audiences based on their viewing habits.

How to Create Ad Groups

Creating ad groups is a straightforward process, but it’s important to get the structure right to maximize efficiency. Here's a step-by-step guide to how to create ad groups in Google Ads:

1. Log in to Google Ads: Access your Google Ads account and select the campaign in which you want to create an ad group.
2. Create a New Ad Group: Click on the “Ad groups” tab within your campaign and then click on the “+” button to create a new ad group.
3. Name Your Ad Group: Choose a clear and descriptive name for your ad group that reflects the theme or product you’re targeting.
4. Select Keywords: Add related keywords that will trigger your ads when users search for those terms. Google Ads will provide suggestions based on your initial input.
5. Create Ads: Write the ads that will be shown when your keywords are triggered. Ensure the ad copy is closely related to the keywords for better relevance and performance.
6. Set Bids: Determine your bid strategy for the ad group, choosing either manual bidding or automated options like Target CPA or Enhanced CPC.
7. Save and Launch: Once everything is set, save your ad group and launch it. Monitor its performance regularly to make necessary adjustments.

Best Practices for Ad Group Management

Managing ad groups involves regular monitoring, testing, and optimization to ensure your ads perform well. Here are some best practices:

• Keep Themes Tight: Focus each ad group on a single theme or product to improve relevance and lead to a higher Quality Score.
• Use Negative Keywords: Implement negative keywords to prevent your ads from showing for irrelevant search queries, which can waste your budget.
• Test Multiple Ads: Create multiple ads within each ad group to test different messages and see which one performs best.
• Monitor Performance: Regularly review key metrics such as CTR, conversion rates, and Quality Score to identify areas for improvement.
• Optimize Bids: Adjust bids based on performance data to get the best possible return on investment (ROI) from each ad group.

How Many Ads Should Be Implemented Per Ad Group?

To maximize your ad group results, it's recommended to have between 3 to 5 ads per ad group. This allows you to test different headlines, descriptions, and calls-to-action (CTAs) while still keeping enough data concentrated to make informed decisions. Google Ads will automatically rotate these ads and prioritize those that perform best, helping optimize your ad strategy.

How Many Ad Groups Per Campaign?

The ideal number of ad groups per campaign varies depending on the scope of your campaign and the variety of products or services you're promoting. However, a good rule of thumb is to start with 5 to 10 ad groups per campaign. This provides a balance between targeted segmentation and manageability, since too few ad groups might limit your ability to target specific audience segments, while too many can make management more complex without necessarily improving performance.
