Why Should I Use Display Advertising? 

We all see online display ads while we’re cruising the internet each day. In fact, according to some digital marketing experts, we all see between 4,000 and 10,000 ads each day. Online ads are extremely prevalent these days and a hugely popular form of advertising. Display ads feature well-designed text, fonts, colors, pictures, graphics, and sometimes even animation!

Display ads are particularly helpful when it comes to raising brand awareness and remarketing to past visitors. They do have a slightly lower direct click-through rate than search ads. However, display advertising does push customers down the sales funnel. It can persuade them to hit the purchase button in their cart on your product or service. The key to display ads is to make them memorable, so that someone will remember your business and search for it later, even if they don’t click on your ad right away.

How to Design Effective Display Ads

Are you ready to design your own AdWords advertisements? They can seem difficult to design, but with the right tools and information, you can build your own display ad campaign! Let’s discuss how to design effective Google AdWords display ads.

Keep Rules and Restrictions in Mind

There are a few rules and restrictions put in place by Google that you will want to remember as you create your ads. For instance, Google display ads need to be under 150 KB, as mentioned above. Additionally, your ads can’t have a white background without a border outline. This is so that ads do not blend in to the background of the website on which they are being served. Facebook has a rule that means that ads can only have 20% text, which includes logos.

It is better to know all the rules before you create your ads so you don’t have to go back and fix them later. Make sure your ads are the correct size, have a border or a colored background, and adhere to text restriction rules.

Consider Your Color Choices

One of the first choices you will make me when designing your ads is the colors you will use. This is an important decision. You will want your colors to stand out on the web page, but on the other hand, you also don’t want them to be overly stimulating. Your colors should also match your company’s branding. You want to keep your colors consistent across the board, or in this case, across the web. It also will confuse your visitor if someone clicks on your ad and is taken to a website that doesn’t match the ad whatsoever.

Images and Graphics

The huge advantage to display ads over search ads is that you get to use visuals in your advertisements. You will need to consider your images and graphics carefully when you are designing your ads. While your text is important, your visuals are what will most likely initially grab your audience’s attention. Try to pick images that will resonate with your audience and elicit the feelings that you are trying to communicate.

Include a Call to Action 

One of the most important, if not the most important, aspects of your ad is its call to action. Urge the people who see your ad to take your desired action. Your call to action should be short, clear, and to the point. Consider a button that says “Buy Now!” or “Read More!” A simple button can be very effective.

Content and Layout

Lastly, when you are designing your ad, try to make it clean and clear. When in doubt, simpler is better. A simple image is more compelling than a complex graphic that is hard to understand. Try not to overwhelm your audience, and certainly don’t include too much text.


Once you are done designing your ads (congratulations!) you might think you’re done. However, an important step in your ad-designing process is to test your ad against another version. This will help you know which version is most effective. It is extremely worth the process and time of creating two different ads and testing them against each other. This process is sometimes referred to as A/B testing.
