In the modern world, advertising effectiveness is directly linked to its visibility. Viewability is a key metric for an ad unit because ads that users don't see don't generate revenue. Let's delve deeper into what ad viewability is, why it is so important, and how it can be improved.

What is Ad Viewability?

Ad viewability is defined as the amount of time during which most of the ad is visible to the user. According to the standards of the Media Rating Council, an ad is considered viewable if 50% of its pixels are on the screen for at least one second for display ads and two seconds for video ads. This means that the ad must be on the screen long enough for the user to notice it.

Yandex goes further, requiring ads to be visible for more than two seconds. Otherwise, the impression is not considered viewable and is not paid for. This strict criterion helps to improve the quality of ad impressions.

Why is Viewability Important?

Simply put, it's all about the money. Ads that users do not see will not be paid for. Ad viewability directly affects its effectiveness and profitability. The closer the ad is placed to content that attracts the user's attention, the more often it is seen, the more ad-related actions users take, and the more often it gets paid for. This makes viewability one of the most important metrics for both advertisers and platforms.

What Influences Ad Viewability?

• Ad placement on the page plays a key role in its viewability. Well-chosen ad placements can significantly increase viewability. For example, ads placed at the top of the page or next to popular content are more likely to be seen by users.
• Device type. Ad viewability on mobile devices is higher than on desktops and tablets. This is because users interact more frequently with mobile devices and spend more time scrolling pages.
• Ad format. Different ad formats demonstrate different levels of viewability. Video ads, for example, usually have higher viewability compared to display ads. Native ads, which are seamlessly integrated into the content, also show high results. Aggressive formats that overlay content can negatively impact user experience but have the highest viewability rates.
• Content density and quality. Content with high informational density, such as long articles or infographics, can increase ad viewability. Users spend more time viewing such materials, which increases the likelihood of viewing the ad. The longer the user stays on the page, the higher the chances they will notice the ad.

Technologies and Tools for Measuring Viewability

There are many technologies and tools for measuring ad viewability. Among them are Western tools like Google Active View, IAS and Russian tools like AdRiver, Weborama. These technologies allow for measuring ad viewability and provide detailed reports that help optimize ad placements.

How to Improve Viewability?

Improving ad viewability starts with analyzing current metrics and identifying problem areas. It is important to consider page load times and the presence of engaging content around the ad units. Fast page load times and attention-grabbing content can significantly improve ad viewability.

• Placement optimization. One of the most effective methods for improving ad viewability is optimizing its placement. Place ad units above the fold and within content so they are visible without the need to scroll. Look at which content blocks attract the most user attention and think about how you can integrate an ad unit nearby.
• Responsive design is very important. Ad units, like the entire site design, should be responsive for proper display on any device. This ensures ad viewability across all platforms and devices, whether it's a smartphone, tablet, or desktop. You may want to create different ad units for the mobile version and desktop to avoid mixing metrics across different devices. Also, consider that ad unit placement may differ for different device types.
• A/B testing. Regular A/B testing helps determine the best ad placements and optimize their viewability. Test different positions and formats of ad units to find the optimal combination for maximum viewability and effectiveness.

User Journey

Ads should not kill your site's metrics. If you overstuff everything with the most conversion-oriented ads, you'll get a short-term spike in profitability, but you'll lose in the long run. It is important to integrate ad units in such a way that they do not interfere with the user consuming the content, but at the same time they understand that they are paying with their attention to the ad for the conditionally free viewing of the content.

Use analytics tools to understand where the user's attention is directed and what behavior patterns can be seen, for example, in Yandex.Metrica or Google Analytics.

Conclusion

Ad viewability is a key metric for both the publisher and the advertiser. The techniques discussed will help improve viewability and increase ad profitability. Remember that user attention is a limited resource and cannot be infinite. You have only a few seconds to capture the user's interest with your content and/or show them an ad. It is important to maintain balance, improve the overall user experience, constantly analyze viewability metrics, and make necessary changes to improve results.
