There is a lot mislabeling. The Stephanie Plum series has been put into Romance but they are not romances. I've seen other cozies and mysteries stuck in there as well. Why? They know it will sell better categorized as a romance.
Not all Chicklit is about the chicks as you put it. I've read plenty that were about the lead female and had strong romantic elements but not a happy ending for the couple. They are a lot like cozies in that way. I've seen Urban Fantasy categorized as romance alot when there is hardly any romantic elements at all.
A more modern way to tell is covers like shirtless hairless men, pretty dresses that go on and on, sexy couples and sweet couples in uncomfortable poses. These are almost always romances.
