What is viewability?

Viewability refers to the measurement of how visible and viewable an ad is to website visitors. It tracks whether an ad was actually seen by users, taking into account factors like ad placement, scrolling behavior, and page layout. Viewability is an essential metric for publishers and advertisers alike because it provides insights into the effectiveness and value of digital ad campaigns.


The MRC and IAB guidelines state that a display ad is considered viewable if at least 50% of its pixels are in the visible portion of the browser window, and the ad remains in view for a minimum continuous duration of one second.

 

The formula for calculating viewability is as follows:

 

Viewability = (Viewable Ad Impressions ÷ Ad Impressions) x 100.

If you are having a hard time getting viewability data for your monetization program, just use the formula above to calculate it yourself!

A good starting benchmark for viewability that we use at diDNA is 80%. If viewability is below this number, there’s likely some room for improvement.

Why Viewability Matters

 

In today's competitive digital advertising landscape, viewability holds immense significance for publishers. High viewability not only increases the value of your inventory but also makes it more appealing to buyers, whether they participate in programmatic ad auctions or engage in direct buys. Advertisers prioritize ad placements that offer high viewability because it ensures their ads are seen by the intended audience, maximizing the potential for engagement and conversions.

Moreover, viewability serves as an indicator of your website's overall functionality and user experience. When your ads have high viewability rates, it demonstrates that your website is functioning properly without timing out, displaying errors, or experiencing other technical issues. This promotes trust and confidence among advertisers, as they can rely on your website to provide a seamless environment for their campaigns.

Another crucial aspect is the direct correlation between viewability and revenue. When your ads are highly viewable, they have a greater chance of capturing users' attention and driving engagement. This, in turn, leads to increased click-through rates, conversions, and ultimately, higher revenue. Advertisers are more likely to allocate larger budgets to publishers with proven high viewability rates, as they see a clear return on investment and value in reaching a receptive audience.

By prioritizing viewability, publishers can enhance the value of their inventory, maximize ad performance, and drive revenue growth. It's a win-win situation where advertisers benefit from effective ad placements, and publishers can maximize their monetization potential. Viewability serves as a key metric for success in the digital advertising ecosystem, fostering mutually beneficial relationships between publishers and advertisers.

The factors that impact ad viewability

Several factors play a crucial role in determining ad viewability on a publisher's website. One of the most significant factors is page load times. Slow-loading pages not only frustrate users but also increase the likelihood of users leaving before ads fully load and become viewable. Optimal ad viewability is closely linked to fast page load times, ensuring that ads have sufficient time to render and appear on the screen before users navigate away.

Ad placement and positioning also heavily influence ad viewability. A sticky ad unit, positioned in a fixed location on the screen as users scroll, tends to have nearly 100% viewability since it remains in the viewport regardless of user interaction. On the other hand, ads placed towards the bottom of a page often suffer from low viewability rates, as users may not scroll down far enough to see them. Implementing techniques such as lazy loading, where ads are rendered at measured scroll distance, can help improve viewability for ads placed further down the page.

The importance of mobile cannot be overstated when considering ad viewability. With the significant growth of mobile device usage, ensuring ads are optimized for mobile screens is essential. Mobile responsiveness is crucial, as ads need to adapt seamlessly to different screen sizes and orientations. Mobile-friendly ad formats and placements that cater to user behaviors on mobile devices can significantly enhance viewability. Additionally, factors like page load times and ad positioning on mobile devices need to be carefully considered to provide a seamless and viewable ad experience.

Considering these factors—page load times, ad sizes and positioning, and the importance of mobile—can greatly impact the viewability of ads on a publisher's website. By optimizing these elements, publishers can improve ad viewability, maximize ad exposure, and create a positive user experience, ultimately benefiting both advertisers and their own revenue generation.

 

The importance of smart ad refresh and lazy load

Ad refresh and lazy load are two valuable techniques that publishers can employ to enhance ad viewability and increase ad inventory on their websites.

Smart ad refresh, when implemented carefully, can be a powerful tool to improve programmatic ad revenue. By refreshing ads after a certain period, publishers can increase the volume of ads being seen by users who spend extended periods on a webpage. However, it is crucial to implement dynamic refresh timers that consider what ads are in view for a user and prevent refreshing ads that are out of view or on another browser tab. Care should be taken to avoid excessive ad refresh, which may lead to user annoyance, negatively impact the user experience, and limit the chances for a user to interact with an ad and lower the CTR (click through rate) further. This generally results in lower CPM values for ads. Furthermore, it may be prudent to disable ad refresh entirely for certain campaigns, particularly direct campaigns that benefit from super high viewability and high click-through rates, and pay a premium for no competition throughout their campaign's delivery. This approach ensures that specific ads remain static and visible throughout the user's session, maximizing their effectiveness.

Lazy load, on the other hand, is a valuable technique that contributes to improved viewability. By implementing lazy load, ads are loaded dynamically as the user scrolls, ensuring that ads are only loaded when they are about to come into view. This approach prevents ads from loading unnecessarily until users reach the specific locations of a webpage, increasing the likelihood of ads being viewable when users are most likely to engage with them. Lazy load optimizes page load times, reduces bandwidth usage, and ultimately enhances the overall viewability of ads on a publisher's website.

By leveraging the benefits of smart ad refresh and lazy load, publishers can effectively improve ad viewability. Ad refresh can maximize revenue potential, but careful implementation is necessary to maintain a balance between refresh rates and user experience. Meanwhile, lazy load ensures that ads are loaded at the optimal moment, increasing the chances of ads being viewable and engaging to users. By combining these techniques with other viewability optimization strategies, publishers can create a positive and engaging ad experience, benefiting both advertisers and their own revenue generation.

 

Ways to improve ad viewability

To enhance ad viewability on your website, it's crucial to follow best practices that optimize various aspects of your ad implementation. Here are some practical best practices to consider:

Optimal Ad Placement Strategies: Carefully consider the placement of your ads to maximize viewability. Ads near the top of a page tend to have lower viewability due to users scrolling past them before they have had time to render. Experiment with different ad placements, such as sticky ad units or in-content placements, to improve ad viewability and user engagement.

Ad Format Selection and Customization: Choose ad formats that are inherently viewable and complement your website's design. Adaptive ad units that bid appropriate ad sizes to various screen sizes and devices are essential for ensuring viewability across various platforms. Additionally, customize ad formats to blend seamlessly with your website's aesthetics without compromising visibility.

Techniques to Optimize Page Load Times: Optimize your website's performance to reduce page load times. Faster-loading pages ensure that ads have sufficient time to render and become viewable before users lose interest or navigate away. Compress images, minimize code, leverage caching, and implement content delivery networks (CDNs) to improve overall page load speed.

A/B Testing and Performance Tracking: Continuously test and optimize your ad placements, formats, and other variables using A/B testing methodologies. Experiment with different strategies to identify the approaches that yield the highest viewability rates. Track key performance metrics, such as viewability, click-through rates, time on page, and engagement, to gain insights into what resonates best with your audience.

Collaboration with Ad Networks and Partners: Foster collaborative relationships with ad networks and partners. Stay informed about industry best practices and emerging viewability standards. Engage in discussions to gain insights and access tools provided by your ad network partners to enhance viewability tracking, ad serving, and optimization.
