Frequently Asked Questions

What makes a good digital marketing dissertation topic?
A strong digital marketing dissertation topic should be specific, timely, researchable, and academically grounded. Because digital marketing changes rapidly, the best topics engage with recent developments (the past two to three years) while connecting to established marketing theory. Avoid topics that are too broad (“the impact of social media on marketing”) and narrow down to a specific platform, behaviour, consumer segment, or industry context.

What research methods are used in digital marketing dissertations?
Digital marketing dissertations use a wide range of methods. Quantitative approaches include online surveys, secondary data analysis (Google Analytics, social media metrics), and experiments. Qualitative approaches include in-depth interviews with marketing professionals or consumers, focus groups, and content analysis of digital campaigns. Mixed methods combine both. The choice should be driven by your research question.

Do I need industry access to write a digital marketing dissertation?
Not necessarily. Many excellent dissertations rely on survey data from consumers, publicly available campaign data, social media content analysis, or systematic literature review. However, if you have access to a company’s marketing analytics data through work experience or a contact, this can provide a distinctive empirical contribution to your research.

What referencing style is used for digital marketing dissertations?
Most UK business and marketing programmes use Harvard referencing. Some use APA. Always check your programme or module handbook for the required style.
