Ads that are easily visible when your pages load and are closer to your content will get higher click-through rates (CTR). This highlights the significance of choosing ads that come in sizes that are easily noticeable. If you select ad sizes that are either too large or too small, users won’t pay attention to them.

You also have to consider the number of advertisers who are running ads in the format that you have chosen. Some ad banners and formats are popular with advertisers. This means that when you use them, you get larger inventories as well as better paying ads.

Some ad formats and banners are optimized for mobile. If most of your users access your site via mobile devices, these ads will undoubtedly perform better on your site compared to other sizes and formats.

What are the Best-Performing Google AdSense Banner Formats and Sizes?

Often, website owners try out different banners in a bid to determine the formats and sizes that work best on their sites. On their part, Google AdSense technicians regularly run tests to determine how ads perform on participating websites. These are some of the best performing ad formats and banner sizes.

1. The Medium Rectangle (300×250)

If you are looking for an ad format that supports text and display ads, and can also work with mobile layouts, consider using The Medium Rectangle. Arguably, the most incredible thing about this ad size is the fact that it is easy to find on your sidebar and within the content areas without annoying users.

It doesn’t come as a surprise that The Medium Rectangle often gets a more significant ad inventory. Consequently, it attracts better-paying ads to your website. The ad format is perfectly-sized for most in-content ads and also has the best click-through rates for most sites.

2. Large Rectangle (336×280)

This ad format is larger than The Medium Rectangle. Similarly, it is also more noticeable but may not fit onto all website sidebars. The ad format also isn’t mobile optimized. If the content area of your website or the sidebar is narrow, the ad can squeeze your content. This isn’t good as far as the user experience is concerned.

The Large Triangle also outperforms The Medium Triangle on your site, especially if it’s placed within your website’s content area between paragraphs. The ad format supports both text and image ads.  Due to its ideal placement and size, The Large Triangle can also attract a good ad inventory.

3. The Leaderboard (728×90)

The Leaderboard is a typical banner ad size, which is perfect for website headers. It supports both image and text ad formats. Nonetheless, The Leaderboard does not support mobile ads.

5. Large Mobile Banner (320×100)

If you are searching for mobile ad formats, look no further than Large Mobile Banner. It has a striking resemblance to The Leaderboard ad format especially when it comes to ad effectiveness. Large Mobile Banner is most effective with mobile devices. It works best if you place it before or just below your website’s header.

What makes this ad banner popular is the fact that it is less intrusive. Similarly, it easily blends with any web design that you choose. Nonetheless, Wide Skyscraper is less effective compared to greater half-page banner ads that tend to attract more user attention towards ads.

For excellent results, you should place this banner ideally next to your content or within the sidebar. Here, it is more noticeable since it allows users to go through your page’s content. However, implementing this ad banner is tricky since it will affect the user experience.

9. The Billboard (970×250)

Arguably, The Billboard is among the most brand-centric ad formats. Since it’s a full horizontal banner ad, you can place it either at the top or at the bottom of your pages. The fact that this ad format offers unlimited space to advertisers means that it often gets better ads.

The Billboard has a small ad inventory. It can also be a hit or miss when implemented since you can never be sure that this ad format will attract a high number of ads for your site. The number of advertisements that The Billboard will attract depends on your website’s content and keywords.

10. The Square (250×250)

Typically, larger ads are more noticeable than smaller ads. Nevertheless, not all sites are designed similarly. If you’re using a simple WordPress theme, The Square can work best for you.

In this case, this ad format can fit seamlessly into your layout and be noticeable in the process. On the flipside, however, The Square‘s ad inventory is small. Therefore, the ad banner will most probably attract low paying ads only.

This ad format can only work well if your site is in a highly competitive niche. In this case, The Square can function effectively without affecting users’ experience.
