Unless you want endless YouTube generated ads after adding your Fiverr gig videos read on…
After doing the first common step of posting my Fiverr gig videos on YouTube. I realized the three choices
for thumbnails were not at the beginning of my videos where my face and gig text are. “custom thumbnails not allowed on this account”. Darn! I thought so naturally clicked “learn more” within YouTube “How to choose a custom thumbnail” . Not much came up specifically but one distinctive video with two guys explaining how to get this feature working. They tell you to turn Google Adsense on and then go back to videos and turn off “Ads” from the pull-down menu…but its not there! You my friend just got fooled and signed up to Adsense. Not nice Google ;-(
REAL simple fix to get the custom Thumbnails, is to confirmed your phone number do that and boom.
