For example, when I was living in Japan around 1996, we needed a kerosene heater for our apartment. We went to the big department store, and they had a lot of different ones. Each of them had a sticker affixed describing the various features and advantages, but they were mind-numbingly similar. But one of the stickers had a photo of Mai-chan, the cheerful and engaging child star of a cooking show that we had enjoyed on Japanese TV a couple years earlier.
My wife pointed it out to me, and we ended up getting that heater. Not because it was any better, but because we liked Mai-chan, and her photo was on it. Of course Mai-chan has absolutely nothing to do with heaters, and we knew it. But we didn't care.
We always called it the "Mai-chan" heater, and even though we left it behind when we returned to the states, I guarantee if I mention the Mai-chan heater to my wife today, nearly 20 years later, she'll smile and know exactly what I'm talking about.
The puppy screenshot in the original post has a similar effect on me. A part of me wants to reach out and pat the cute dog on the head. But I can't. But I can click the button, which is what he obviously wants me to do. Sure it's not at all rational. But it motivates people. I suggest keeping the dog and adding it all your advertising. Make it your mascot. You can't go very wrong with a puppy!
