A featured deal on the Kobo eBook site looks like this (this is not clickable and the deal may have ended ten years ago by the time you see this, so apologies if this was your most-anticipated book ever and you can’t buy it at the price shown):
Seems fine, right? Now imagine if for some reason the site wasn’t rendering the image of the book properly. Here’s the same ad, with the book cover obscured:
No big deal, right? But let’s say you don’t have time to click the Learn more link when you see it, so you make a note to check later. But later the ad is no longer in rotation. Still no big deal, because you made a note of the title of the book–oh wait, you didn’t, because if the image doesn’t display, the text has no mention of the book title anywhere. Whoops. And this is applied inconsistently as well, as here’s another featured ad from the same page and it does mention the title in the last paragraph:
This isn’t world-ending bad design, of course, it’s really more of a nitpick. Still, an ad for a book should perhaps mention the book, no?
