Understanding Google Display Ads

What are Google Display Ads?

As a business in the digital age, it's essential to meet customers where they are — online. One of the avenues to do this is through Google Display Ads. They are visually engaging ads that are shown on over 2 million websites and apps in the Google Display Network. In other words, Google Display Ads give businesses a chance to reach customers wherever they're browsing online.

But here's the real kicker: these ads are not just about wide reach. They're also about targeted reach. Google Display Ads allow businesses to tailor their ads to specific demographics, times, and regions. This focused targeting means your brand is placed right in front of the people who are most likely to be interested in what you offer.

Importance of Google Display Ads for E-commerce Businesses

In the bustling digital marketplace, making your brand stand out can seem like a daunting task. But that's where Google Display Ads come in. They're a powerful tool for businesses, especially for e-commerce, to cut through the noise and capture the attention of potential customers.

Google Display Ads not only increase your brand's visibility but also play a pivotal role in building trust and driving conversions. They complement your SEO strategies by tracking the performance of specific keywords, helping you target your SEO content more effectively. This dual approach of SEO and display ads can boost your brand's online presence and growth.

At First Pier, we believe in the power of Google Display Ads. We've seen how it drives visibility, increases interaction, and most importantly, boosts sales. That's why we are committed to helping our clients leverage the full potential of Google Display Ads.

As Steve, our topic expert at First Pier, often says, "The path to unlocking online success lies in harnessing the power of Google Display Ads."

With the right understanding and strategic use of Google Display Ads, you can amplify your brand's reach and take your e-commerce business to new heights of success.

In the next sections, we'll delve deeper into the nitty-gritty of Google Display Ad sizes — a crucial aspect of maximizing the efficiency of your Display Ads. Stay tuned!

The Basics of Google Display Ad Sizes

Creating successful ad campaigns is a combination of art and science. One key aspect that impacts the effectiveness of your Display Ads campaign is the size of your ads. Understanding Google Display Ad sizes is an essential part of maximizing your ads' efficiency and success.

Size Limit for Google Display Ads

When it comes to Google Display Ad sizes, it's important to understand the specifications and size limits. For AMPHTML ads, the dimensions of all ads must be declared using a meta tag - <meta name="ad.size" content="width=W,height=H">. The supported ad dimensions for AMPHTML are the same as those for HTML5.

When uploading a zip file containing your ad assets, the total size of the compressed zip should not exceed 150KiB (153600 B) - this includes your primary HTML document and up to 39 media assets.

Common Sizes for Google Display Ads

There are a variety of ad sizes supported by the Google Display Network. The most common google display ad sizes include the Medium Rectangle (300x250), Large Rectangle (336x280), Leaderboard (728x90), Half Page (300x600), and Large Mobile Banner (320x100).

For example, the square ad size (250x250) is available for text and display ads on both desktop computers and mobile devices. However, inventory is usually limited for this size, and these ads may perform poorly as a result.

Another popular size is the leaderboard banner (728x90). This ad size sits at the top of the webpage and is typically more noticeable to viewers.

It's important to note that while some ad sizes may be more popular, this doesn't necessarily mean they will perform better. The performance of an ad size can vary depending on a variety of factors, including the content of the ad, the audience, and the placement of the ad.

The Role of Ad Sizes in Display Campaigns

Ad sizes play a crucial role in the performance of your Display Ads campaigns. Larger ad sizes generally perform better than smaller ones, as they are more likely to capture the viewer's attention.

However, this doesn't mean you should only use large ad sizes. Google's ad inventory impacts the availability of display ad space in its network. Google tends to have a lot of inventory for medium and small ad spaces, and less inventory for larger ad spaces.

As our expert Steve at First Pier explains, "If you only publish large-sized ads, you might achieve a high click-through rate (CTR), but you may not be reaching a diverse audience or achieving a broad placement. To maximize the reach of your display ads, it's essential to choose a mix of the most popular and best-performing ad sizes for which there is sufficient inventory available."

In the following sections, we will go into more detail about the top performing Google Display Ad sizes and how to choose the right size for your e-commerce business. So, stay with us as we continue to navigate the world of Google Display Ads!

Top Performing Google Display Ad Sizes

As we dive deeper into the realm of Google Display Ads, it's crucial to understand the top-performing ad sizes. Our expert Steve at First Pier has handpicked the five most effective ad sizes based on Google's internal data, and these are widely recognized in the industry as the go-to dimensions for high-performing ad campaigns.

Medium Rectangle (300x250)

This ad size is commonly referred to as the "medium rectangle". Owing to its higher availability of ad inventory, it is a top performer in the Google Display Network. The 300x250 ad size can be strategically placed mid-article or on the sidebar, breaking up text and catching the reader's attention.

Large Rectangle (336x280)

Leaderboard (728x90)

The "leaderboard" ad is another high-performing ad size. Typically placed at the top of a webpage, this horizontal ad format offers a broad visibility space. However, it's crucial to ensure that you're purchasing top-of-page slots, as bottom-of-page slots aren't viewed as frequently.

Half Page (300x600)

This size can accommodate more information and creative designs, making it a popular choice for advertisers.

Large Mobile Banner (320x100)

As the name suggests, the "large mobile banner" ad size is specifically designed for mobile devices. It's the fifth top-performing ad size according to Google and is the mobile counterpart to the leaderboard. It's a great way to reach your audience on the go.

Understanding and utilizing these top-performing Google Display Ad sizes can significantly improve your ad performance. But remember, while size does matter, it's not the only factor determining your ad's success. The quality of your ad content and its relevance to your audience are equally important. In the next section, we'll guide you on how to choose the right Google Display Ad size for your e-commerce business. Let's continue our journey to mastering Google Display Ads!

How to Choose the Right Google Display Ad Size for Your E-commerce Business

Navigating the world of Google Display Ads can seem complex, but it doesn't have to be. At First Pier, we're experts in helping businesses like yours make the most of their online advertising. When it comes to selecting the right Google display ad sizes, there are three key factors to consider: understanding your audience, conducting A/B testing, and considering the available ad space.

Understanding Your Audience

The first step in selecting the right ad size is understanding your audience. This involves analyzing the demographics, interests, and behaviors of your target market. By using Google Ads Audience Insights, you can gain a wealth of information about your audience, helping you create more effective ads. Remember, the goal of your ads isn't just to reach as many people as possible, but to connect with potential customers who are likely to be interested in your products or services.

A/B Testing and Performance Analysis

Once you have a solid understanding of your audience, it's time to test different ad sizes. This is where A/B testing comes in. By running two different ad sizes simultaneously, you can compare their performance and determine which one is more effective.

At First Pier, we believe in the power of data. Monitoring and analyzing the performance of your ads is crucial to optimizing your campaigns. Regularly review your campaigns and use the data gathered to make necessary adjustments. Remember, maximizing ROI with Google Display Ads is a continuous process of testing, learning, and optimizing.

Considering the Available Ad Space

Finally, consider the available ad space on the websites and apps where your ads will be displayed. The size and location of your ads can significantly impact their visibility and effectiveness. Larger ads such as the half-page (300x600) or the leaderboard (728x90) can be more prominent and thus more likely to catch a user's attention. However, the availability of these ad sizes may be limited on some websites or apps, so it's important to consider this when planning your campaign.

In conclusion, choosing the right Google display ad sizes for your e-commerce business involves a combination of understanding your audience, testing different ad sizes, and considering the available ad space. At First Pier, we're here to help guide you every step of the way, unlocking the immense potential of Google Display Ads to boost your online success.

Future of Google Display Ads: Changes in 2023

As we continue our deep dive into the world of Google Display Ads, it's crucial to stay informed about upcoming changes and how they may affect your e-commerce business. Specifically, there are some significant changes coming by the end of Q1 2023 that will impact the way ads are displayed on Gmail. Let's explore these in more detail.

Gmail's Discontinuation of Certain Ad Templates

By the end of Q1 2023, Gmail will no longer support certain ad templates such as Single Image Ad and Custom HTML Ad. If your current campaigns use these templates, you'll need to adjust your strategy to keep your ads running effectively. But don't worry, at First Pier, we're here to guide you through these changes and ensure your campaigns continue to thrive.

There are two key options you can consider to navigate this transition:

  1. Stay within Display campaigns: You can continue running Display campaigns, but you'll need to use the supported ad templates and formats.

  2. Move to new campaigns: Alternatively, you can transition to other types of campaigns like Discovery campaigns or Performance Max campaigns, depending on your specific goals.

Transitioning to Discovery Campaigns and Performance Max Campaigns

Let's take a closer look at these two new campaign types and how they can benefit your e-commerce business.

Discovery campaigns are customizable and can run ads on Gmail, YouTube, and the Discover feed. This offers a broader reach and more opportunities to capture your audience's attention. Learn more about Discovery campaigns.

On the other hand, Performance Max campaigns utilize automation to run ads across all Google Ads channels. This means your ads can reach customers no matter where they are on Google, from search results to YouTube videos, and everything in between. Learn more about Performance Max campaigns.

Transitioning to these new campaign types can ensure your ads continue to reach your audience effectively. As a bonus, they may also introduce new opportunities to engage your customers and expand your reach.

At First Pier, we understand that these changes may seem daunting. But with our expert guidance, we can help you navigate these transitions smoothly and effectively. We're dedicated to helping your e-commerce business adapt and thrive in the ever-changing digital landscape.

In the next section, we'll delve into creating effective Google Display Ads for your e-commerce business. Stay tuned!

Creating Effective Google Display Ads for Your E-commerce Business

When it comes to building a successful online campaign, we at First Pier understand that it's not just about choosing the right Google Display ad sizes. It's also about creating engaging and effective ads that resonate with your audience and drive conversions. Let's explore some strategies to achieve this.

Using Responsive Display Ads

Remember, size matters, but so does flexibility. Google Ads offers a fantastic feature called responsive display ads. These ads are designed to automatically adjust their size, appearance, and format to fit just about any available ad space. This means your ad could show up as a small square on one site and a large rectangle on another.

By using responsive display ads, you're ensuring that your ad fits perfectly in any ad space, maximizing your potential reach. You can upload multiple assets (like images, headlines, logos, and descriptions), and Google's AI will automatically generate optimized ads for you.

Utilizing AMPHTML Ads for Mobile Devices

In our fast-paced digital world, loading speed can make or break an ad's performance, especially on mobile devices. That's where AMPHTML ads come in. These are ads built with AMP (Accelerated Mobile Pages), which load faster than regular ads. As Google's support page explains, faster load times can improve ad visibility, increase click-through rates, and generate more revenue for your business.

Creating AMPHTML ads might require a bit more technical know-how, but the payoff in terms of performance can be substantial. If you're not sure how to create these ads, we're here at First Pier to help guide you through the process.

Engaging Users with HTML5 Ads

HTML5 ads are another great option for creating engaging and interactive display ads. These ads allow you to incorporate advanced features like video, audio, and complex animations into your ads, making them more engaging and likely to capture users' attention.

However, you should remember that Google supports image files in only three formats: JPG, PNG, and GIF. And the file size of any display banner should not exceed 150KB, regardless of its dimension. So, while HTML5 ads can be more engaging, they also need to be optimized to ensure they load quickly and don't consume too much of your audience's data.

Creating effective Google Display Ads for your e-commerce business is a combination of art and science. It's about choosing the right Google Display ad sizes, creating engaging ad content, and leveraging the right ad formats. And, as always, we at First Pier are here to help you every step of the way.


In the ever-evolving digital marketplace, navigating the world of Google Display Ads can seem complex. However, understanding the role and significance of google display ad sizes can help you make informed decisions that boost your brand's visibility online.

As our expert, Steve, emphasizes, there's no one-size-fits-all when it comes to Google Display Ads. Different ad sizes cater to different objectives and audiences. The most common sizes, such as Medium Rectangle (300x250), Large Rectangle (336x280), Leaderboard (728x90), Half Page (300x600), and Large Mobile Banner (320x100), offer a broad range of visibility options across various platforms.

Remember, the success of your ad campaign is not solely dependent on the size of your ad but also on your messaging, creative elements, and audience segmentation. Regularly conducting A/B testing is key to understanding which ad sizes and formats bring the most engagement and conversions for your brand.

Looking ahead, Google's discontinuation of certain ad templates by the end of Q1 2023 encourages a shift towards Discovery campaigns and Performance Max campaigns. These changes highlight the need for adaptable and responsive advertising strategies.

Using responsive display ads, AMPHTML ads for mobile devices, and engaging HTML5 ads are all ways to create effective Google Display Ads. These formats bring together the power of eye-catching visuals, compelling content, and strategic placement to engage customers at various stages of their buying journey.

At First Pier, we understand that every brand is unique, and so are its advertising needs. Our team continually monitors results, analyzes data, and adjusts strategies to ensure your Display Ads campaign aligns with your business goals and delivers the highest ROI. Whether you're new to Google Display Ads or looking to optimize your existing campaigns, we're here to guide you through the process.

In conclusion, Google Display Ads, despite their lower CTR compared to Search Ads, play a crucial role in enhancing brand awareness. By choosing the right Google Display Ad sizes and utilizing the various ad formats effectively, you can maximize your online advertising efforts and boost your e-commerce business growth.

Remember, advertising is a journey, not a destination. As you explore the possibilities with Google Display Ads, you'll discover new opportunities to connect with your audience, increase brand visibility, and drive conversions.
