Performance

Online display ads are effective with the right targeting, creative strategy, and performance tracking.

How Effective Is Online Display Advertising Today?

Online display advertising has been a core component of digital marketing for decades. But with ever-increasing competition for user attention, many advertisers wonder: Are display ads truly effective? The answer largely depends on how well they are optimized.

Display ads can be highly effective when used correctly and can influence consumer behavior toward buying your product or using your service. They offer broad reach, visual appeal, and precise targeting options. However, their effectiveness varies based on factors such as ad design, targeting, placement, and user intent.

How to Improve Display Ad Effectiveness

Metrics for Display Ads: Click-Through Rate (CTR)

The effectiveness of display ads is often measured by CTR, which represents the percentage of users who click on an ad after seeing it. CTR is also frequently used as the key performance indicator (KPI) for an online display campaign.

The CTR is calculated by Amount of Clicks / Amount of Impressions * 100

Industry benchmarks for display ad CTRs vary. Here are some general figures:

Average Display Ad CTR0.35%

0.35% on average, depending on industry and platform.

Retargeting Ads CTR0.70% - 1.00%

Usually higher than standard display ads.

Display versus retargeting click-through rate comparison

While these numbers may seem low, display ads still contribute to brand awareness and overall marketing success when combined with other advertising strategies.

Another useful KPI to evaluate the performance of your display ads can be pay-per-click (PPC). With PPC you not only look at the percentage of users who click on your ad, but also compare it to the amount you need to invest. PPC is calculated by ad spend / amount of clicks.

So even if one website or campaign performs better at first glance because the CTR is higher, the results may look different when you consider the overall outcome. Maybe another campaign has a lower CTR, but the CPM is also much lower, which means you may end up paying less per click and generating more total clicks overall.
