When we use the present perfect, there is a connection with now. The action in the past has a result now:

I can’t find my bag. Have you seen it? (= do you know where it is now?)

 

Compare gone (to) and been (to):

Amy is back home now. She has been to Italy. (= she has now come back)

Present Perfect Continuous Tense is used for the actions that started in the past and still continues.

We use the present perfect continuous in this way, especially  with how long, for … and since … . The activity is still happening (as in this example) or has just stopped.

Where have you been? I’ve been looking for you for the last half hour.

 

You can use the present perfect continuous for repeated actions:
