What topics to choose for a marketing dissertation?

Heyya, folks! How are you all doing! The name’s Alex Gilbert and I am a marketing student currently pursuing my bachelor’s degree from a reputed university in London, England. My final semester is just around the corner and that’s why I have decided to start working on my dissertation so that I can have enough time to finish it within the due deadline. The only thing that I’m confused about is choosing the right topic. I’m not stressed about how to write my dissertation United Kingdom as much as I am stressed about choosing the right topic. Can anyone suggest what kind of topics are best for a marketing dissertation? Should I incline more towards case studies or something like that?
