I'm guessing you mean on your profile? Just because someone looks at a profile doesn't mean they're looking to add you. Some people just float through profiles. Also, each time a profile is viewed it counts as a hit. Including when you go to your own profile.
I rarely send out friend requests. And i turn down at least half of requests i get. And i keep my friends list clean out. My profile has over 25,000 hits. Doesn't have anything to do with number of friend requests. Some people just randomly send out friend requests to strangers just to get a bigger list. The only really valid ones are people you have interacted with. And that requires you getting involved in chats or forums.
