Professional image best practices

  1. 1. Profile photo excellence: use a recent, professional headshot with good lighting. Your face should take up 60–70% of the frame.
  2. 2. Banner strategy: complement your professional brand. Include your tagline, showcase your work, or highlight your expertise.
  3. 3. Post image impact: posts with images receive about 2× more engagement. Keep branding consistent.
  4. 4. Company page cohesion: ensure the logo and cover work together for a professional presence.
  5. 5. Mobile optimization: most LinkedIn traffic is mobile — test how images appear on small screens.
