Hello

I am interested in this field and have work and research experience in this field.

That's great, and it's nice to meet you...

I am a second-semester PhD Student from Pakistan... I want to focus on these areas to find a good research topic...

Can you please help me if you have some knowledge related to that area?

Given its newness, I suggest you research social listening or listening to social networks. I refer you to my article:

I am also s second semester Ph.D. Business student from the U.S. and I'm working on digital marketing - more narrowly focused - as a central Research Objective. My advice is to define your central Research Objective you think you want to explore for your dissertation now (it can evolve), read a number of literature reviews, outline the topic you want to explore and then write a literature review. Ideally this should be integrated into your coursework for a central area of focus. Hope this helps.
