LinkedIn Headline Optimizer

LinkedIn allows up to 220 characters in your headline. Most default headlines are under 50 characters because LinkedIn auto-fills them with your job title and company name. The highest-performing headlines use 100 to 220 characters because every extra character is a chance to include a keyword, a skill, or a proof point that helps you rank in recruiter searches. The scoring tool above gives full marks (15/15) for headlines that use at least 181 characters. Anything under 50 characters scores zero because it signals you have not customised your headline at all.

LinkedIn truncates your headline in three different places. On desktop search results, only the first 60 characters are visible. On mobile search results, only the first 46 characters show. In the comment section under posts, only the first 50 characters appear next to your name. Your full 220-character headline is only visible on your actual profile page. This means the first 46 to 60 characters of your headline are what most people will ever see. The search results preview above shows you exactly where LinkedIn cuts your headline in each context so you can make sure your job title and strongest keywords appear before the truncation point.

Yes, and it should be near the beginning. Recruiters search LinkedIn by job title more than any other keyword. If your headline starts with your target role, you will appear in more search results. The scoring tool above checks whether your target role appears in the first 40 characters (full marks) or later in the headline (partial credit). It also handles abbreviations: if your target role is "Machine Learning Engineer" but your headline says "ML Engineer," the tool recognises that as a match. The key is to avoid burying your title after filler words like "Passionate about" or "Aspiring to become" — lead with the title, then add context.

Separators like the pipe (|), middle dot (·), slash (/), and bullet (•) break your headline into visually distinct sections. A headline like "Product Manager | Fintech · B2B SaaS | ex-Stripe" is scannable at a glance — the reader can see your role, your niche, and your proof point without reading a full sentence. Headlines without separators tend to read as a single run-on phrase that is harder to parse quickly. The tool above gives full marks (10/10) for two or more separators and partial credit for one. You do not need more than three or four separators — beyond that, the headline starts to feel cluttered.

Social proof is any element in your headline that borrows credibility from an external source. This includes company names (especially recognisable ones like "at Google" or "ex-McKinsey"), quantified metrics ("500+ clients," "$10M in revenue"), credentials ("Certified AWS Solutions Architect"), and authority markers ("Speaker at Web Summit," "Published in Forbes"). Social proof matters because it gives the reader a reason to trust your claims. A headline that says "Growth Marketer" is generic. A headline that says "Growth Marketer | Helped 200+ SaaS companies reduce CAC by 30% | ex-HubSpot" is specific and credible. The scoring tool above detects 12 types of social proof patterns and gives 15 points when at least one is found.
