Below is a video published by Google Adsense.
In the video, the Adsense team claims that the most viewbable position is not the top of the page but rather right above the fold (0.50sec) as seen in the screenshot below:
According to the video, “above the fold” is the highest viewable position across both desktop and mobile web.
The video also claims that the most viewable ad sizes are vertical ad units because they stay longer as user move around the page.
What’s your take on this?
Do you earn more from vertical ad units especially those placed on the sidebar?
