Her videos get people excited, that's why so many of them have super-high view counts. She never really tends to go "overboard" with her performances, and she performs at so many places that she's basically become a staple on awards shows.
But the thing I like best is that her songs can be huge in their own right without the need for a video/performance. Like how California Gurls just shot out of nowhere to #2 in its first week without any help from that stuff.
