Choozle What is Viewability

What is viewability?

What is viewability? How is it measured? Is it the same as above-the-fold? Let’s clear it all up in plain, human English.

Simply put: Viewability is a metric that helps digital marketers understand how much of their ad inventory was seen during a campaign.

The purpose of viewability is to help advertisers pay only for the ads that users will see. However, there are many marketers and advertisers who will argue that viewability is a bogus metric.

 

How is it measured?

Viewability is measured by embedding code into a creative that fires when the ad is served and then measures if, when, and how the creative is viewed.

A display impression is viewable if 50 percent or more of its pixels appear on the user’s screen for at least one continuous second. A video impression is viewable if 50 percent of its pixels appear on-screen for at least two consecutive seconds.

 

It sounds like viewability is the same thing as above-the-fold, no?

That’s a common misconception. To understand the difference, let’s first cover the basics of above and below-the-fold.

Think of it like a newspaper folded in half, hamburger-style. Anything you see without having to unfold the paper (on the top half) would be considered above-the-fold, or ATF, and whatever you have to open the paper to see (on the bottom half) is below-the-fold, or BTF. On a website, below-the-fold is anything a user has to scroll down to see.

Oftentimes, viewability is mistaken as being the same thing as above-the-fold because you would assume that an ad that’s placed ATF equals viewability, right? Maybe not. Technically, if an ad is above-the-fold, it is more likely to be actually seen by a user, but ad position does not equate to viewability.

 

Is there a way to tell viewability in Choozle?

In a word: Yes! For those with Strategic Accounts, Choozle has several partners who offer viewability tracking and reporting for an additional CPM. Reach out to your Strategist to see how you can implement those into your campaigns.

Regardless of what type of account you have with us, Choozle proactively monitors the viewability of inventory run through our platform and applies to a platform-wide block list any sites with poor viewability. (P.S., You guessed it, viewability is a close cousin of brand safety.)
