The sizes of your ads play an important part in the overall monetization of your site. The more ad sizes within an ad slot, the greater the competition and the higher the yield potential. We determine the optimal sizes for a given ad slot based on your site's layout and our expertise of which sizes yield the best results. You have full control over what ad sizes you would like available in each ad slot. To request changes, contact your Proper Media Account Manager.
Note, sizes can be modified at any time by Proper. No changes are required to the tags on your site.
Where Can I See My Size Settings?
You can see which sizes are available in each ad slot in the Proper dashboard on the Ad Units page under the Ad Manager tab.
