One thing I keep reading on the Internet is the expression “How does it look like?” Sadly, this sentence doesn’t make any sense. The correct way to express the thought is either “What does it look like?” or “How does it look?” For example:
Although both questions are correct, there may be a slight difference in meaning. “How does it look?” is usually answered with a mere adjective:
A: It looks good. / It’s all right. / It’s ugly.
Of course, the thing you are asking about doesn’t have to be “it”, for example:
A: I think he’s cute.
On the other hand, if you ask “What does he/she/it look like?”, you are inviting the other person to give you a more precise description (often using the word “like” and a noun, but not necessarily):
A: He looks a little bit like Johnny Depp and has beautiful blue eyes.
