Present perfect simple and Present perfect continuous

We use the Present perfect simple:

A to talk about actions and states which began in the past and continue until now.

B to talk about finished actions in the past when we don't say exactly when they happened.

C when we say how much/many things we've done, how many times something has happened, or how far we've travelled.

We use the Present perfect continuous:

D to talk about an action in progress or repeated over a period of time up until now.

E for a recent finished or unfinished activity that explains something in the present.

We use for and since with the Present perfect simple and continuous when we give the duration of an action or state.

We use FOR when we give the total period of time. 

We use SINCE when we give the starting point of the state/action.

 

We use the Present perfect simple to talk about

• actions and states which began in the past and continue until now:
  The company has produced games for thirty years.
• experiences and finished past actions when we don't say exactly when they happened:
  Graphics have become incredibly complex.
• how much/many things we've done, how many times something has happened, or how far we've travelled:
  I've played this game about ten times.

We use the Present perfect simple with state verbs.

How long have you known about this company?

Signal words for the Present perfect simple include ever, never, already, just, still and yet.

We use the Present perfect continuous to talk about

• an action in progress or repeated over a period of time up until now:
  People have been giving me positive feedback in the comments.
• an activity that started in the past and may still be continuing:
  I've been working with three sponsors.
• an unfinished or recently finished activity that explains something in the present:
  Have you been working all night? You look exhausted!

We do NOT use the Present perfect continuous with state verbs.

I've wanted to be an influencer since I can remember.

NOT I've been wanting to be an influencer since I can femember:

Signal words for the Present perfect continuous include all day, recently and lately.

We use the Present perfect simple to focus on the result of a recently completed action, and the Present perfect continuous to focus on the activity and emphasise its duration:

• I've made a new video, it's awesome! (focus is
  on the result = a new video that is finished)
• I've been working on a new video lately. (focus
  is on the activity = working on the video which
  is not finished).

However, sometimes we can use either tense with Little difference in meaning, in particular when we talk about work or study:

• I've worked in fashion since I was nineteen.
• I've been working in fashion since I was nineteen.

For and since

We use for and since with both the Present perfect simple and Present perfect continuous to state the duration of an action or state.

• We use for with periods of time:
  I've had over a thousand followers for a year.
• We use since to indicate the moment in time when the state or action started:
  These videos have been multiplying since 2007.
