"CHECK", "CHECK OUT", "VIEW", "LOOK AT" SOMEONE'S PROFILE (Meaning and Difference)

Question

In the context of a website, for example, a dating site, I would like to know the meaning of the following expressions:

• "to check someone's profile"
• "to check out someone's profile"
• "to view someone's profile"
• "to look at someone's profile".

Do those expressions have to do with turning one's eyes towards something or do they mean to examine something or do they mean to read something?

What should I think of or should I imagine when I hear or see those expressions?

I have some examples:

1. Someone likes your profile. Why not CHECK OUT their profile and see if you're interested.
2. Susan just VIEWED your profile!
3. Megan Fox just LOOKED AT your profile!
4. Alizee just CHECKED your profile!

Answer 1

The meaning of each example is the same. It is the connotation that is different. Connotation varies among subcultures, but for me Ex.1 brings a sense of excitement and a little urgency, implies new possibilities, and warrants a high level response (action or reply). Ex.2 is only informative, FYI, no sense of importance, and doesn't warrant a response. Ex.3 is also informative, but draws a level of curiosity that warrants a low level response. Ex.4 is informative as well but implies importance, perhaps as if one is waiting for such an notification.
