Hey guys,
I've been testing Youtube ads for retargeting of some Ecom product but results have been quite disappointing.
The avg CPC was $4,35 which of course is crazy high (geo is US), normally for this product CPC would be way way lower than that.

Since this is retargeting, the users targeted have already shown interest in the product so the only reason for such low CTR I can think of is something within the ad.
I'm not very knowledgeable of Youtube ads but, based on the ad-preview, this is the only CTA that's shown to users during the video:

Do you see something sub-optimal with this? Is there something else in your experience that might explain such low CTR?
