Honestly, I have no idea about ad campaigns. However, I've felt that the ad itself wasn't good enough.

And, when you say "a typical YouTube ad is 30 seconds" doesn't mean you have to make one so long, you could have considered it more as an upper limit instead of a goal. Your message was simple, and i've felt the ad was unnecessarily slow and long. Being more specific, you lost me exactly after the first 8 seconds.

On the other hand, the ad taught me that it's possible to buy japaneses candies easily and where i could get them. If someday I, or one of my friends, want japanese candies, I could simply point to your website. (And in fact, I already made a friend interested about it before reading your post).

Lastly, the ad itself is boring, maybe with some background music or even a voice more like "Hatsune Miku" could been a little more fun to see entirely.
