Hello Friend,
The thing to do is look at the LITERATURE REVIEW in an article that is interesting to you. Most professional journal articles will have a lit review, or it might be called "background" or something similar.
You have to read that section in an article that interests you, and it has to be a recent one. That way, it will show all that people like you have been doing in recent years. If you want to know a good topic to use, just look at the topic of the article that was recently published. That will give you a sense of what is being done in the field.
Read one article's intro, lit review, and conclusion, and you will be ready to start. That is your "way in" to the subject.
If you still have trouble, find another article. Soon, you will have read so many marketing articles that no one will be more prepared than you to tell what topic should be covered next.
*** Another important way to prepare is to read about the various research designs: survey, case study, grounded theory, correlative, etc.
:-) I hope that helps you! If you just want a list of topics, google this: list, research topics, "marketing management" "real estate"
