Best Viewability Vendors For Publishers in 2020

Updated on: January 8, 2024
Looking for a specialized vendor to track and report on your viewability? Then, we got you a handy list.

When running ad campaigns, whether in desktop web, mobile web, or mobile app; ad viewability is one of the top concerns that bubbles up often in a publisher’s mind. Although it can be tracked in your ad server or your ad-tech vendor’s dashboard, you might require a dedicated vendor at a point of time.

So, When Should You Start Looking for an Ad Viewability Vendor?

We all know that no publisher can ever display 100% viewable ads on the website. However, the positive aspect is that viewability can be increased to a certain level by optimizing ads and implementing effective strategies. But, to what extent? When you realize that you are no longer able to enhance your viewability score, then it’s high time to look for a vendor*.

Besides, publishers cannot control and track all variables related to ad viewability as there are external factors (such as ad fraud) that affect the viewability score. And in many cases, they need to prove the buyers that the ad inventories are viewable inventories and by real humans. In such an instance, you need a vendor who is specialized in viewability measurement and can help you with detecting low viewable ads on the website and the reasons behind that.

Not only this, but a vendor can also tell you about your best-performing audience, ad formats, placements, and so on with respect to viewability. Moreover, with the advancement of technologies, you can expect a lot more from the viewability providers in the industry.

*Please note that the viewability vendors may or may not help you with the optimization of ads. However, they can help you with providing insights into viewability and suggestions to improve the score. Ultimately, it’s up to you to learn from the advanced insights and messages to reach intended audiences.

However, choosing the right may be difficult for some publishers. After all, there are hundreds of companies that aren’t MRC-accredited and claim they can help you with your objectives.
