D378: Digital Marketing Science

D378 is Digital Marketing Science in the Marketing Analytics specialization of WGU's Master of Science in Marketing, in the third term. The program guide lists it at 4 competency units, one more than most courses around it.

WGU describes foundational knowledge across social media, email and content marketing, marketing automation, SEO, paid search (PPC), conversion rate optimization (CRO), mobile marketing and web analytics, plus how a digital strategy is developed and integrated.

It offers the HubSpot Marketing Software certification, and the content aligns with the OMCA certification.

What D378 Covers

Key Concepts Explained

The Science in the Title

In the analytics track, each discipline is judged by what it measures. Treat every activity as a hypothesis: what you expect to change, which metric will show it and how long you will test.

Metrics by Discipline

Match a key metric to each channel: organic traffic and rankings for SEO, cost per click and conversions for paid search, open and click rates for email, conversion rate for CRO.

Automation and Data

Automation depends on clean data and clear rules. Explain how contacts are segmented, what triggers a message and how performance is tracked.

Typical Assignments and How to Approach Them

Testing, Experiments and Learning

The word science in the title points to a testing mindset. Rather than assuming what works, set up comparisons and let results guide choices.

• Change one thing at a time: headline, image, audience or offer.
• Split traffic fairly: randomly and in similar sizes.
• Run long enough: avoid stopping on early noise.
• Record the result: what you learned, even when the new version loses.

If a task asks for a plan, show a table with the hypothesis, the metric, the sample, the duration and the decision rule. For example, a plan might compare two email subject lines on 1,000 subscribers each over 48 hours, with click-through rate as the measure. Showing the decision rule in advance proves that you understand why tests are run.

Allocating a Digital Budget

Analytics-focused tasks often ask how you would spend a budget across channels. Show your thinking with a simple allocation and the reasons for it.

The percentages are illustrative; your own numbers should reflect the case. Explain how you would review them after the first month and move spend toward the channels that meet their targets.

Self-Check Questions

Does each discipline in your answer have a metric and a target? Have you described how you would test an assumption? Is automation explained with real data inputs and a measurable goal? As the course carries four competency units, expect the work to be broader than in a standard course, so check your plan against every rubric aspect early.

Where Students Get Stuck

• Breadth. Use a one-page map to keep disciplines straight.
• Metrics without targets. State what counts as success.
• Not testing. Include how you will compare alternatives.
• Tool focus. Strategy and objectives come before software.

Study Tips for D378

• Allow extra time; this course carries one more competency unit than most.
• Pair each discipline with its main metric and a typical benchmark source.
• Practice reading a small A/B test result and explaining it.
• Keep notes if you take the optional certification, since they help with tasks.
