Optimizing profile for conversions

Display name: Full name + value proposition keyword (e.g., "Jane Smith | AI Engineer")
Bio: Lead with what you do, who you serve, proof (numbers), and CTA
Location: Include if relevant to your niche (e.g., "San Francisco, CA" for tech)
Website: Link to your most important conversion page (not just homepage)
Avatar: Professional headshot, face visible, good lighting, contrasting background
Header: Banner showing your work, product, or personal brand tagline

Bio formula (160 chars max)

{What you do} for {who you serve}
{Proof/credentials}
{CTA or link description}

Example: "Building AI tools for indie hackers | 10K+ users | Free at example.com"
