LinkedIn profile optimization comes down to nine building blocks: photo, cover image, headline, About, Featured, Experience, contact info, Follow or Connect, and a custom URL. LinkedIn Help sets clear rules for each, such as PNG or JPG up to 8 MB for the photo and 3 to 100 characters for the URL (as of November 2026). LinkedIn's own profile optimization tool, Profile Writing Assistance, is limited to a select group of Premium subscribers. Everyone else can have an AI chat such as Claude draft the headline and About text from their own notes, and check Search Appearances to see whether it helps. What goes live stays your decision.
My LinkedIn posts are drafted by Conny, my AI employee for content, and I approve every one of them. Two of her rules fit a profile just as well, and the prompts below follow them: she invents no personal facts, and when in doubt, the spot stays blank. My own profile is at linkedin.com/in/kevin-welter, linked in the footer of this website. For posts, see AI for LinkedIn Posts: A Step-by-Step Guide; everything else is on LinkedIn with AI: Posts, Profile, Reach.
The LinkedIn profile checklist
Photo and headline: the first impression
The photo. LinkedIn explicitly allows "an illustration, caricature, or other artistic rendering of yourself", but "your profile photo must reflect your likeness." LinkedIn may remove logos, landscapes, animals, stock imagery or fictional characters, so an AI portrait has to show you. How to generate AI images is covered in Creating AI Images: Free and Free to Use.
The headline. The text below your name is, per LinkedIn Help, "displayed in search results", and you can rewrite it any time via the Edit icon in your introduction section. Help gives no character limit; LinkedIn's Talent Blog (February 2025) says: "You get 220 characters", and advises against spending them on your job title, which is shown below anyway.
Three LinkedIn headline examples, made up, not from real profiles:
- "Tax advisor for trade businesses in Ohio | Receipts go digital, not into a shoebox"
- "I help painting contractors hire apprentices through Instagram | Owner, 12 employees"
- "Privacy consultant for medical practices | Data protection explained plainly | Talks and workshops"
The pattern: who you help, with what, and one detail that only fits you, with each search term used once.
About, Featured and Experience
About. LinkedIn describes it as the place to "express your mission, motivation, and skills" and suggests limiting the text "to one or two paragraphs"; bullet points are fine. The Talent Blog puts the cap at 2,600 characters (post from April 2024) and recommends the first person. Lead with your strongest sentence and end with one action.
Featured. Work samples you pick yourself: posts, articles, images, documents and links, unlimited in number, 400 displayed. Content there "will not be discoverable through search", and viewers must be signed in to see it.
Experience. Entries must reflect real professional ties such as employment, contract work, internships, volunteering or board service; being a customer doesn't count. Skills attach to positions, up to 100 in total.
Follow and URL. Whether visitors see Follow or Connect first is set under Settings & Privacy, Visibility, Followers, "Make follow primary". You change the custom URL under "Public profile & URL" on the right of your profile page.
How your profile gets found: on LinkedIn and on Google
On LinkedIn. People search results are, in LinkedIn's words, "unique to each member", shaped by the searcher's activity, network and past searches. Testing with a couple of accounts says little; profile views are the better indicator. More keywords don't automatically help: use accurate terms and avoid keyword stuffing, because "if a profile appears overly optimized, it may be impacted by spam detection systems." Search Appearances, under Analytics, shows how often you appeared and for which job titles.
On Google. Google, Bing or DuckDuckGo show your public profile, a simplified version of your full profile. Its settings control which sections appear; turning it off hides it from search tools but can make account recovery harder. Changes can take "several weeks or months at times" to show up in search tools, and LinkedIn doesn't control that. Nobody can guarantee a top spot, on either side.
Second language. A profile in another language can be added on desktop only, and changes to the primary profile must be repeated there.
Using AI as your LinkedIn profile optimization tool
LinkedIn's Profile Writing Assistance suggests text for the headline and About sections, but only for "a select group of LinkedIn Premium subscribers". Without it, a general AI chat works, as long as it writes from your material. Start a note: services, audience, three real results, two sentences you'd say about yourself. Stored as project knowledge, it's always at hand, see How to Use Claude Projects Right.
A brief for the headline:
Goal: Five options for my LinkedIn headline, in English,
each 220 characters or fewer.
Reader: <who should view my profile, for example owners of
trade businesses in the Midwest>
Material (my note): <services, audience, three real results,
terms people should find me by>
Limits:
- Only facts from my note. If something is missing, write [ADD].
- Use each search term once at most, no keyword lists.
- No superlatives like "leading expert".
Format: five options, each followed by one sentence on who it suits.
A brief for the About section:
Goal: Text for the About section of my LinkedIn profile, first person,
one or two paragraphs, plus up to five bullet points.
Material (my note): <paste>
My tone (two of my posts or emails): <paste>
Structure:
1. First sentence: who I help and with what.
2. How I work, with one result from my note.
3. Close with a single action: <website / booking / message>.
Limits:
- No numbers, clients or experiences that aren't in my note.
If something is missing, mark it with [ADD].
- The result is a draft. Below it, list every claim I need to check.
How AI picks up your tone is covered in Can AI Write Emails in My Voice?; the general form for any text is template 8 in my Prompt Templates, and the basics are in Writing with AI: A Beginner's Guide. Then check every line against your note, because an AI writes what sounds plausible, not what's true (AI Hallucinations: Why AI Makes Things Up). You paste the final text in yourself.
Common LinkedIn profile mistakes
- Extras in the name field. Per LinkedIn, only first and last name belong there; titles and offers go into the headline.
- Keyword stuffing. Repeating the same terms in headline, About and every position doesn't help and can hurt visibility.
- Logo instead of a face. A company logo as your profile photo goes against the guidelines.
- Inflated positions. Experience must be accurate; client relationships are not positions.
- A profile for the company. Personal profiles aren't meant for organizations, LinkedIn says; that's what LinkedIn Pages are for. Whether a Page is worth it is covered in LinkedIn Company Page vs. Personal Profile.
- Forgetting the second language. Your German profile keeps the old headline.
- Unchecked AI text. People who know you notice an invented number.
For business contacts, the profile is the foundation; the search itself is covered in Finding B2B Leads: LinkedIn and Alternatives. How profile and posts add up to a brand is in How to Build a Personal Brand on LinkedIn.
Frequently asked questions
What is the LinkedIn headline character limit?
LinkedIn's Talent Blog says 220 characters (February 2025); the Help page doesn't state a number.
Is there a free LinkedIn profile optimization tool?
LinkedIn's own writing help is a Premium feature for a select group. To see whether you're being found, use Search Appearances in the Analytics section of your profile; LinkedIn Help doesn't list it as a Premium feature. For drafting, any AI chat works with the briefs above.
How long until Google shows my updated profile?
Per LinkedIn, several weeks or sometimes months, and LinkedIn doesn't control that refresh.
Does my network see when I edit my profile?
LinkedIn notifies your network about job, education and work anniversary changes, controlled under "Share profile updates" or with the "Share with network" toggle while editing. Anyone who views your profile sees your edits as soon as you save them.
What to do next
Write your note today, have Claude draft five headlines and an About text with the briefs above, fill in every [ADD] yourself, then work through the checklist. In four weeks, check Search Appearances for the job titles you were found for.
The twelve briefs, a cheat sheet and a fill-in page for your own brief are in the prompt templates file on my free templates page; with it comes my weekly newsletter "From the Engine Room". If you want Conny and the other AI employees as ready-made templates, they're in the Premium tier of my community AI Employee Framework. If AI should also draft your posts, read AI as Your LinkedIn Ghostwriter. What a post needs to get read is covered in How the LinkedIn Algorithm Works in 2026. A PDF works well as a Featured work sample, see How to Make a LinkedIn Carousel with AI.
