Your Headline Gets the First Look. The Rest May Never Get One. Write Accordingly.
Eight out of ten people who see your headline will read it. Two out of ten will read what comes after. Write accordingly.
Eight out of ten people who encounter a headline will read it. Two out of ten will read what comes after. This is not a finding about blog posts or content marketing. It applies to email subject lines, LinkedIn headlines, resume summaries, presentation titles, and any piece of writing where the first line is visible before the rest.
The implication is uncomfortable. Most of what you write, most of the people who could have read it, never will. The only guarantee you have is the first line.
Why Labels Fail
Professional communicators have understood this for decades. Most professionals still treat headlines as labels. They write the content first, add a title at the end that summarises what they just wrote, and move on. “Marketing Tips for Beginners.” “Resume Advice.” “How to Use LinkedIn.” These titles are accurate. They make no promise worth investigating. They create no gap between what the reader knows and what they might know. There is no reason to click, open, or read on.
What a Strong Headline Does
A strong headline does one of two things. It makes a specific, credible promise, such as “How to Cut Your Resume From Two Pages to One Without Losing Impact,” or it creates genuine curiosity based on something counterintuitive, such as “The Resume Section Most Hiring Managers Skip.” In either case, the reader finishes the headline with a reason to continue. Closing that gap requires engaging with what comes next.
The contrast between the two titles for the same content makes this concrete. “Email Etiquette in the Workplace” versus “The Email Habit That Makes You Look Junior to Every Senior Colleague.” The first is a category label. The second is a specific, slightly provocative claim that anyone who has ever worried about professional email will want to resolve. Same subject matter. Completely different pull.
Beyond Blog Posts: LinkedIn, Email, and Everything Else
A student’s LinkedIn headline is the first text a recruiter sees after their name. “Marketing Student at Hanyang University” locates them. “Content Strategist Building Brand Voice for B2B Technology Clients” positions them. The second version tells a reader what the person does and who they do it for. The first version simply describes a status.
Email subject lines follow the same logic. “Following Up” gets opened less than “Quick question about the Kakao application, two minutes.” The second version is specific, low-pressure, and tells the reader exactly what they are agreeing to before they open it. In Korean professional communication, the concept of 첫 인상 (cheot insang) captures this precisely: the opening gesture that earns the next moment. Your headline is the cheot insang of every piece of professional writing you produce. Write it last, after you know exactly what case you are making. Then make it earn the read.

Frequently Asked Questions
Why is the LinkedIn headline the most important line on your profile?
Because it is almost always the only line that gets read. In search results, connection requests, and notification previews, the headline is the only text visible alongside your name and photo. Eight out of ten people who see your headline will read it. Two out of ten will read what comes after. The headline is your entire pitch for most of the people who encounter your profile.
What should a strong LinkedIn headline include?
A specific role or function, what you do or solve (not just what your title is), and optionally a differentiating detail. ‘Marketing Manager at X Company’ tells the reader your title. ‘B2B content strategist helping SaaS companies convert technical expertise into pipeline’ tells them what you do and who you do it for. The second version takes a position. The first one simply occupies space.
What are the most common LinkedIn headline mistakes?
The three most common are: using only the job title (too generic), using the current employer as the primary identifier (the employer’s brand, not yours), and using buzzwords without specificity (‘dynamic leader,’ ‘passionate communicator’). The antidote to all three is specificity — the more precisely you describe what you actually do, the more useful the headline is to both the people looking for you and the algorithm.
