If you were curious about what vampires looked like in real life, you would probably do what Bella did. People on the internet have been making jokes about her searching online for what vampires look like. Do you think that Dracula would show up? Yup, that would be correct. But since this is another universe with supernatural beings, of course you would want to make sure what they actually look like.
So if you were living in a world where Robert Pattinson was a vampire, then the looks of a vampire are different. None of them would look like Nosferatu. So just allow Bella search what they actually look like.
