Using and making the most of an advertising space, regardless of its dimensions, is vital. Ads must be well designed and attractive, and they should give viewers a reason to click. However, it’s also reasonable to say that the larger the ad, the more likely it is to grab attention and get in front of your target audiences. It’s hard to ignore an ad that takes up most of your screen.
Of course, that doesn’t mean you should disregard other ad sizes. Ad unit sizes impact and influence audiences differently, and over the last few years, we’ve changed our recommended ad sizes to help businesses increase their reach and enhance their performance.
We’ve picked apart data from our network of more than 37,000 advertisers to explore how recommended ad sizes perform, and now we’re passing on those insights to you.
Conversions and cost
The larger the ad, the more it’s going to cost. That’s a given. As a consequence, you’ll need to be able to allocate a significant sum to ensure a large ad gets in front of as many people as possible.
Our research has found that the larger the ad, the more likely it is a viewer will click on it and subsequently become a customer, so the cost can often be entirely justified. But is a large ad exactly what your business needs?
AdRoll recommends advertisers upload multiple versions of each of our six recommended ad sizes, as that allows our ad placement algorithm to test them and give priority to the ones that get the most clicks and conversions. This means that AdRoll advertisers can see the benefits of each ad size without manually tracking its performance.
Variety is the spice of life
While large ads are undeniably effective, incorporating a mix of ad sizes into your ongoing marketing efforts can be incredibly helpful.
Ad inventory—the amount and type of ad space that’s up for grabs in online ad auctions—is a competitive business. There is only a certain number of high-quality ad placements available, so there just aren’t enough to ensure your message reaches everyone you’re targeting. You know that saying about not putting all your eggs in one basket? That’s what we’re getting at.
Websites tend to have more inventory available in the smaller sizes because these are easier to build into most web pages. Having a range of popular ad sizes guarantees you’ll get more opportunities to show off your ad and means you’ll be able to achieve more while spending less.
