To optimise your LinkedIn profile, start by having a professional profile photo and a compelling headline that clearly defines your expertise and career goals. Use the summary section to tell your story, highlight your achievements, and mention key skills related to your industry. Ensure your experience is detailed, focusing on accomplishments rather than just duties. Add relevant skills and seek endorsements from colleagues. Customise your LinkedIn URL for a more professional appearance, and engage with content relevant to your field to increase visibility. Finally, connect with industry professionals to expand your network.
