If you’re pouring money into Google ads, it’s critical to be aware of the banner ad sizes that generate the most amount of impressions, clicks, and sales.

Display ads are shown to users on websites that are not search engines.

They have the purpose of driving brand awareness by reaching a larger audience on different blogs, news sites, or niche websites. At the same time, they can also be used for remarketing purposes to improve conversions.

Google Ads come in different sizes which is it’s important to know how to optimize them properly to bring the best results.

Unfortunately, not having a correct understanding of banner ad sizes is one of the biggest mistakes made in online marketing.

It’s also one that could cost you a lot of money.

But it doesn’t have to be the case.

While using a banner maker can help in this respect, knowing how to properly optimize your ads can still be quite tricky, which is why we decided to write this article.

top performing banner ad sizes

According to Google, these are the most common ad sizes that you should take into consideration. On top of that, we made a list for you that mentions the top performing banner ad sizes so check them out:

Medium rectangle (300×250 ad size)

This type of banner ad is the most compact one out of all these options so it doesn’t take up too much space on a web page. It performs well when it’s embedded within text content or when it’s placed at the end of an article. Because of the compact size, advertisers tend to favor it because it’s convenient to display. At the same time, it’s a good option when you’re just getting started with display ads.

Large rectangle (336×280 ad size)

Even though this banner ad size doesn’t get as many impressions as the first one, it’s still a popular option for advertisers. Since it’s similar to the medium rectangle, it performs best when it’s placed within text content or at the end of a post. Because it’s slightly bigger than the 300×250 ad size, it means that you will have more ad inventory.

Leaderboard (728×90 ad size)

This type of banner ad is called like this because it’s usually displayed noticeably at the top of a web page. If you want to get your ad in front of as many people as possible, then this is a good option to consider. Also, because you get more ad inventory, you can increase your earnings when text and image ads are enabled. Google advises using this banner ad size on forum sites.  

Half page or large skyscraper (300×600 ad size)

Despite its name, the size of this type of banner ad does not cover half of a page. However, it does take up the most amount of space compared to the large banner sizes. This means that, as an advertiser, you have a lot more elbow room to get your message noticed. But this comes with the pressure of needing to create stunning visuals that draw people in and getting them to click on your banner ad.

Mobile leaderboard (320×50 ad size)

As you can tell from the name, this ad format is optimized for mobile devices. Even though it’s one of the smallest mobile banner sizes available, it should definitely be used as a way to maximize impressions and improve CTRs on mobile.

Why Google Ads Dimensions Are Important

The dimensions of display ads have been developed for different purposes and use cases.

Essentially, the size of a banner ad can impact how a user sees it, or even if they notice it.

Despite the fact that the differences in sizes are not that major, they can make a huge difference in proving their effectiveness.

In the end, your goal is not just for people to see your ad, but rather to get them to click on it and then convert the leads into customers.

This is where banner ad sizes come in handy.

As an advertiser, you want to pick the right banner size ad so you can maximize your campaign reach.

Luckily, we can give you a starting point in this article. This means that you will be able to focus on creating visuals that can bring you results.

However, keep in mind that a specific banner size doesn’t guarantee the success of an ad campaign but it’s definitely something to start with.

Conclusion

These top-performing sizes represent only the first stepping stone in banner ad creation.

The other aspects you should consider are:

  • The copy you use on the banners;
  • The colors;
  • The CTA;
  • The design.

To get started with display advertising, just consider these five sizes first and go from there. Do a few different A/B tests to figure out which size works best for the audience you’re targeting.
