What Is a Marketing Portfolio? (And Why You Need One)

A marketing portfolio is a curated collection of your work—case studies, campaign assets, writing samples, client testimonials—that demonstrates your skills and expertise.

• Employers and clients want proof of results.
• A strong portfolio differentiates you from other marketers.
• It’s your personal brand hub: a place where people can see who you are, what you do, and why you’re the right fit.
