Quality and trust
Viewability
Definition
Whether an ad was actually visible on screen, rather than merely loaded. The common standard is 50% of pixels in view for one second.
Why it matters if you sell your own ads
Viewability is what advertisers use to argue your inventory is worth less. Placements above the fold and in-content generally measure better, which is a good reason to price them higher.
