Viewability Rates by Ad Size

  • Try interactive ads like rich-media ads, sticky ads, and pop-up ads when the user is about to exit. Since the user is already ready to exit, this will not hurt the user experience but will instead get you viewable impressions.

  • Use server-side header bidding. It shifts the workload from the website to the server, improving the user experience and ad viewability.

Ad latency vs. impression change

You can improve ad loading time with strategies like Asynchronous tags and Content Delivery Network (CDN) to load ads quicker and increase viewability.

What Is Next After Viewability and vCPM for Cookie-less Era? It’s Attention

As the adtech ecosystem trails in the vital cookieless era, publishers and advertisers prioritize the attention metric more than viewability.

Attention metric is measured with various parameters such as viewability, creative size, ad position, eye tracking, page frequency, etc. It measures how users interact with the ad and to what extent.

While the attention metric includes such extensive insights, viewability measures only the opportunity for ads to be seen. This data is not enough and will not contribute much to the results and ROI.

That is why attention is next after viewability, and it is gaining prominence. The reason is cookie demise and the decreased consumer attention span due to the oversaturation of ads and content online.

There are more chances of introducing pricing models that emphasize attention, like vCPM for viewability. The key to adapt all these dynamic changes is maintaining a good user experience.

The changes you make to the website by keeping users at the forefront will always keep you ahead. Also, you can see a consistent rise in ad revenue, or in the least case, you will not face a severe downfall due to sudden changes in trend.

True Views, Higher Revenue Potential

In the ever-changing adtech landscape, the auction system moves towards true value and demands accuracy in everything it does.

In that sense, you should embrace vCPM and ad viewability next.

Focus on meaningful ad views that matter and positively impact ad revenue. Prepare flexible ad inventory that attracts high prospect demands, improves market value, and increases ad yield.

By doing so, your website will stay strong and resistant to cookie demise, changes in the diversity of programmatic channels, and the rise of attention metrics. Specifically, the ad inventory with a higher viewability rate is easy to move forward to a digital landscape where attention matters more.

Hence, you can enjoy constant revenue flow irrespective of market fluctuations.
