Banner content and design rules
The left third belongs to your face. Everything you want read goes centre or right.
Content: value proposition, social proof (logos, metrics, awards), a content or product showcase, a CTA. Design: text centred or right-aligned because the profile circle crops the left, large high-contrast type, brand colours, room around the photo, readable on mobile; avoid clutter, low-res images and generic stock or quote graphics.
Most banners fail on placement, not taste.
