One of the most common questions beginners ask after signing up with Google AdSense is which are the highest performing Google AdSense banner sizes?
Some Google AdSense ad formats are more noticeable, which means they get more clicks and bring more revenue.
In this article, we will show you the highest-performing Google AdSense banner sizes and formats, and where to place them for the best results.
How to Properly Setup Google AdSense Ads in WordPress?
By default, you can easily place AdSense ads in your website’s sidebar. Some WordPress themes may also have dedicated areas to display ads.
However, the best way to manage your Google AdSense ads in WordPress is by using an ad management plugin. We recommend using AdSanity, it is super easy to use and allows you to easily insert ads into sidebars, post content, and anywhere else you want.
Why Some Google AdSense Banner Sizes and Formats Work Better?
Google AdSense comes with several banner sizes and ad formats that you can add to your WordPress website. However, not all of them produce the same level of results.
Ads that are closer to the content and easily visible upon page load will get you a higher CTR (click-through rate). You need to make sure that you choose an ad size that is easily noticeable. Some of the Google AdSense ad sizes are too small, and some could be too large to affect user experience.
Next, a factor that affects ad performance on your website is how many advertisers are running ads for that format. Some ad formats and banners are more popular among advertisers, which means using them gets you a larger inventory and better-paying ads.
Lastly, some ad formats are optimized for mobile devices. If mobile users make the most of your traffic, then these ads are going to perform better on your website than other sizes.
Top Performing Google AdSense Banner Sizes and Formats
Most website owners try different banner sizes to determine which formats work best for their websites. Google AdSense engineers also continuously run their own tests to see how ads are performing on participating websites.
We have done several testing with Google AdSense over the years on our own websites. Below are the top-performing Google AdSense banner sizes and ad formats that offer the best value for your advertising real estate.
1. The Medium Rectangle (300×250)
This ad format supports both display/text ads, and it can also be used on mobile layouts. The best part about this ad size is that it’s easy to fit in the sidebar or inside the content area without annoying users.
That’s why this ad format gets a larger ad inventory, that means more and better-paying ads for your site. Since it’s perfectly sized for in-content ads, it is also reported to have the best CTR for most websites.
2. Large Rectangle (336×280)
A large rectangle takes the second position on our list. It is larger and more noticeable than the medium rectangle ad above, but it may not fit in all website sidebars and is not mobile optimized.
If your website’s sidebar or content area is a bit narrow, then the ad could squeeze the content, which is not good for user experience.
That being said, the large rectangle could easily outperform the medium rectangle on your website if placed inside the content area in between paragraphs. It supports both image and text ads.
Due to its size and ideal placement next to content, this ad size gets a better ad inventory as well.
3. The Leaderboard (728×90)
The leaderboard is a traditional banner ad size that is perfect for the website header. It supports both text and image ad formats but doesn’t support mobile ads.
Since the leaderboard is ideal to be placed on the top (inside or immediately after the website header), it gets more ads, which means better ads for your website. Due to its size and prominent placement, it performs fairly well on most websites.
4. Half Page aka Large Skyscraper (300×600)
A large skyscraper is a wide vertical banner also known as half page due to its size. It gets attention from advertisers who want more ad space to effectively communicate their message during retargeting.
It is becoming more popular among publishers because it tends to give more exposure to brands which means better-paying ads.
You can place the large skyscraper in the sidebar or next to the content. However, due to its size, it may not be a good fit for all websites.
5. Large Mobile Banner (320×100)
A large mobile banner is a mobile ad format, and it is equivalent to the leaderboard ad format in terms of effectiveness but for mobile devices. Ideally, it works best when placed on top just below the header.
Since mobile traffic makes up a good chunk of users for most websites, this ad format gets a better ad inventory.
It can be placed as a less intrusive ad and as an alternative to the medium rectangle ad format.
6. Mobile Leaderboard (320×50)
A mobile leaderboard is half in height compared to the large mobile banner ad format. It is slightly less effective but also less intrusive and offers an even better ad experience on smaller mobile devices.
Mobile ads are popular among advertisers, which means it gets a sizable ad inventory. With proper placement, it can work really well with your mobile traffic.
7. Wide Skyscraper (160×600)
The wide skyscraper is a vertical banner ad that is designed specifically for narrow sidebars. It supports both image and text ad formats and is popular among advertisers.
It is a less intrusive ad option and can easily blend in with your website design. However, it is less effective than wider half-page banner ads, which tend to draw more user attention toward the ad.
8. Portrait (300×1050)
A portrait is a slightly wider and longer vertical banner. Due to its size, this ad format attracts brand-centric advertisers who want more ad space for their message.
It is ideally placed next to the content or in the sidebar, where it is more noticeable as your users scan the contents of your page. The tricky part is to implement it without affecting the user experience on your website.
9. The Billboard (970×250)
The billboard is another brand-centric ad format. It is a wide horizontal banner ad that can be ideally placed on top or bottom of your pages. It tends to get better ads due to the space it offers to the advertisers, but it has a smaller ad inventory.
Depending on the content and keywords of your website, it could be a hit or a miss if it fails to attract enough ads for your website.
10. The Square (250×250)
Generally, larger ads are considered more noticeable. However, not all websites are designed in the same fashion. If you are using a minimalist WordPress theme, then this small square ad format could beautifully fit in your layout and still be noticeable.
The downside is that it has a smaller ad inventory which could result in low-paying ads. However, if your website is in a competitive industry, then it can work really well without affecting user experience.
