5 Best Google Ads Display Sizes To Increase Your ROI

Here are 5 best performing ads sizes that you can use Google Ads and AdSense.

1. 300 x 250 (Medium Rectangle)

This ad size is popular among advertisers. A medium rectangle size works well for mobile, text and display ads. Usually they put 300×250 ads embedded within the text content or at the end of their articles.

2. 336 x 280 (Large Rectangle)

Compared to the medium rectangle, this ad size doesn’t fit for mobile display ads. So if your ad campaign doesn’t target mobile users, a 336×280 ad would be a great alternative for a 300×250 since they both can be used the same way.

3. 728 x 90 (Leaderboard)

Unlike the rectangle ads (medium or large), leaderboards tend to perform well on top or above your content page. Marketers usually use this ad size for forums.

4. 300 x 600 (Half Page)

If your campaign wants an impactful ad, then you should use a half page ad. You will have a lot of room to communicate your product or services and hook your target audience with this ad size.

5. 320 x 100 (Large Mobile Banner)

If you only want your ads to cater only to mobile users then a 320×100 can do the job effectively. You can have doubled pixel height with this size which allows you to have more space to work with your ad compared to other standard mobile banner sizes.

How Would a Wrong Google Display Ad Size Affect Your Campaign?

Every Google Ad gets different results and click through rate depending on its size and having only one or 2 sizes will limit the locations available for your ads to show throughout the Google Display Network.

Tips: Making a Google Display Ad

1. Always Have the Right Format

Google only allows specific file formats for your display Ads and those are:

• JPG
• PNG
• GIF

As a rule of thumb, JPEG has the most compression options that would allow you to adjust your file size better in case you need to change it.

2. Keep Your Ad Clear and Simple

Always remember that people only take a few seconds at most when looking at advertisements on a page. So in order to catch your audience’s attention, you should have a high quality image but make sure it can be recognized easily  and the text on your headline be as clear and concise as possible. 

In addition, your ad should convey the value of your service/product as they see your ad. You can use context words that could get their attention and build trust while telling them what they are missing out if they let your ad pass by.

3. Stay True to Your Brand

Customers like consistency. Consistency to your brand can build trust and increase your page’s conversion. You can do this by coordinating your ads to your brand or landing page. An example of this is avoiding colors that could clash with your logo or other branded images.

4. Utilize a Direct To Call Action

Since the goal of your ad is to convert customers, you should use keywords that could urge them into taking action. These words could be see, try or click, in combination with words that could also make them want to click on your ad as they see them.

5. Test Your Display Ads

Your ads wouldn’t be complete if you don’t test it to find out what’s the best. Making two variations of your ad could let you know what works best and what part should need changes to further improve the effectiveness of your ad. 

These variations to your ad shouldn’t be big, you can use different call to actions, different wordings and some little changes on the image could be enough.

Using Google Experiments inside of Google Ads, you can quickly determine which is more effective and keep iterating on that design.
