First of all, Welcome to the forum.
Internet marketing is a very vast concept, so it would be a little bit difficult to share all the information about it. Internet marketing is all about marketing and promoting products or services online.
I am sure you will require more information than this, so one thing we can do is that you share your basic interests or motives (or about your work or job); I would recommend you to search about it on the web. You will get a lot of information from google and youtube itself.
