ADTAGS

In my experience of building banner ads I've learned there are limits on ad submission sizes. For example Google Ads has a cap on the package ad size not to exceed under 150 kb no matter that file type including Gifs, AMPs, JPEGS. Hence this can limit potential creative. Adtags on the other hand remove the ad package size obstacle. However in order to take advantage of this new freedom a third party or an upgraded account with Google Ads is required to host your ads that generate the Adtags. The example shown use a third party resource.
