What do marketers do? A clear look at the role and how AI is changing the field

Marketing sits at the center of how organizations grow. It connects products and services with the people who need them, using a mix of data, creativity, and strategy to drive results.

You see strong marketing every day. Major product launches from brands like Apple build momentum long before anything is available to buy. Other companies rely on shared values to connect with their customers; the clothing brand Patagonia comes to mind.

What do marketers do?

At a high level, marketers identify audiences, understand what those audiences need, and communicate value in ways that lead to action, whether that’s a purchase, sign-up, download, or increased awareness.

In practice, marketers research audiences, shape messaging, launch campaigns, and measure what works to improve results over time.

On a day-to-day basis, marketers:

• Study customer behavior to understand what drives decisions
• Shape messaging and tell stories that make a product or service feel relevant
• Stay connected to customers through channels like email, apps, and social media
• Launch campaigns across digital and traditional platforms
• Track what’s working and adjust based on real results

These responsibilities reflect what marketers do across industries. The work is both analytical and creative, requiring an understanding of people as well as the tools and platforms to reach them effectively.

That same thinking—how brands build connection and create value over time—is at the center of CSU Global’s Bachelor of Science in Marketing. The program explores product and brand management across both goods and services, with a focus on creating value for specific audiences, from early ideation and planning to execution and refinement. It culminates in a capstone course in marketing strategy and execution, where students apply what they’ve learned to real-world scenarios.

While the day-to-day work can vary, these responsibilities typically fall into a few core areas.

1. Market research and audience insights

Marketing work often begins with understanding who you’re trying to reach. This includes analyzing customer data, studying competitors, and identifying trends. The goal is to answer: Who is this for, and what do they care about?

2. Strategy development

Once the audience is clear, marketers build a plan. This might include defining goals, selecting channels like social media, email, and search, and setting a budget.

3. Content creation and campaign execution

Marketers develop content that attracts and engages audiences. This can include blog posts, ads, videos, emails, and landing pages. Campaigns are then launched across selected platforms.

4. Performance tracking and optimization

Marketing is highly measurable. Marketers track metrics like website traffic, conversion rates, and return on investment (ROI). Based on results, they refine campaigns to improve performance over time.

These responsibilities show up across a wide range of roles, from digital marketing and content strategy to brand and product marketing.

How AI is changing marketing

Artificial intelligence is changing how marketing gets done, but not why it works.

AI tools can now help generate content, analyze data, personalize messaging, and optimize campaigns. As a result, the role of marketers is shifting to a greater focus on strategy, judgment, and understanding emerging technologies that are changing the way organizations connect with their audiences.

The fundamentals haven’t changed. Marketing still depends on understanding human behavior, building trust, and creating something people want to be part of. AI can support that work, but it can’t replace it.

This shift is reflected in how marketing is taught and practiced. CSU Global’s Bachelor of Science in Marketing emphasizes both the technical tools and the strategic thinking needed to adapt as the field evolves.

How a Degree Can Prepare You for Marketing

While some people enter marketing through experience, earning a degree can help build a strong foundation and stand out to employers.

CSU Global’s undergraduate marketing degree includes 30 credits of core coursework, completed across ten 3-credit courses designed to build skills progressively.

Students start with foundational concepts in marketing and leadership, including Applying Leadership Principles and Introduction to Marketing, then move into deeper study of how consumers think and make decisions in Consumer Behavior. From there, courses like Product and Brand Management and Integrated Marketing, Promotions, and Advertising focus on how brands are developed, positioned, and brought to market.

As students advance, they explore broader and more complex areas of the field, including International and Multi-Cultural Marketing, Digital Marketing, and Strategic Marketing. They also gain hands-on experience with data and insights in Marketing Research.

The program culminates in Capstone: Marketing Strategy and Execution, where students apply what they’ve learned to real-world marketing challenges.

CSU Global undergraduate alumni report a median annual salary increase of $29,000 within three to five years of graduation, and 89% of graduates are employed. Those results speak to the degree having a solid return on investment, even more so because CSU Global is designed for working adults, offering 100% online, 8-week classes.
