what is the difference between Article writer/ content writer/ copy writer/ Ghost writer?

Ghost writers write articles for others. They will be paid, but they won't get credits.
I think article writer chooses his own topics to write while content writer has to write according to given topics.
I don't know what's this copy writer :blink: :dry:

Article writer- writes according to his choice.
Content write- is almost same but in some cases can write as per sit's demand
Copy write- mostly writes for advertisements' script or short notes used for publicity.
Where as the
Ghost writer writes for other 'so called' writers for good money.
