After reviewing thousands of design portfolios and hiring designers for client projects, I've noticed patterns in what separates portfolios that land $10k+ projects from those that don't. Here are the mistakes costing you premium clients.

The Wrong Case Studies Stop showing:
Personal projects without clear goals
Dribbble-style eye candy
Projects without business context
Work from five years ago
Instead, showcase:
Real client problems solved
Measurable business impacts
Strategic thinking process
Recent, relevant work
Presentation Matters Your portfolio should:
Load in under 2 seconds
Work flawlessly on mobile
Show prices confidently
Include clear call-to-actions
Client-Focused Language Replace "I designed a website" with "The new website increased conversions by 40%." Premium clients buy outcomes, not deliverables.
Pro Tip: Have a "ghost" portfolio of your best work that's only shown to qualified prospects. This creates exclusivity and helps justify premium rates.
Remember: The goal isn't to show everything you can do. It's to show exactly what your ideal clients need to see to hire you.
