LinkedIn's headline field defaults to your current job title, which is the single most wasted piece of real estate on most profiles -- 'Marketing Officer at XYZ Ltd' tells a viewer almost nothing about your actual value. A stronger headline uses the full available space (up to 220 characters) to combine your role, a concrete value statement, and relevant keywords recruiters search for, such as: 'Digital Marketing Specialist | Growing SME visibility through SEO & social campaigns | Ex-XYZ Ltd.' Keywords matter because LinkedIn's internal search and Google both index headlines, and recruiters frequently search by skill or title keyword rather than browsing profiles manually -- a headline with no searchable terms is effectively invisible to that search traffic, regardless of how strong the rest of the profile is.
