LinkedIn profile optimizer
Paste your headline and About section and get an honest review for what you want from LinkedIn: a job, clients, an audience or a network. You get a score, the fixes that matter most, missing search keywords and rewrites written from your own facts.
How do you optimize a LinkedIn profile?
Start with the two things strangers actually read. Your headline follows you everywhere: next to your name in search results, comments, invitations and the feed. Your About section is where someone who clicked decides whether to message you. Both should say what you do, who it is for and why you are worth talking to, in words the right person would search for.
This tool reviews both against your goal, because a profile written to get hired reads differently from one written to win clients. It checks the setup with fixed rules, then an AI review tells you what a stranger understands, which search terms are missing, and what to change first, with rewrites that keep your facts.

What the LinkedIn profile score measures
| Score | What it measures | How it is worked out |
|---|---|---|
| Headline | Whether someone seeing only your name and headline knows what you do and why it matters to them. | AI review against your goal. |
| About section | Whether the opening earns the click on "see more" and the rest ends with a next step. | AI review against your goal. |
| Searchability | Whether the terms a recruiter or buyer would type are on your profile. | AI review of the keywords you use and the ones you are missing. |
| Profile setup | A full headline, a real About section, a way to reach you and no stock phrases. | Fixed rules. Each gap costs points. |
The LinkedIn profile problems we see most
A headline that is only a job title
"Marketing Manager at Acme" is the default, and it tells a stranger nothing about what you are good at or who you help.
An About section that starts with your history
"I started my career in 2012..." spends the only visible lines on the least interesting part. Lead with what you do now.
Stock phrases
"Passionate, results-driven team player" appears on thousands of profiles. A specific result or example does the same job and is believed.
No next step
If someone wants to hire you or work with you, the end of the About section should tell them how: message you, email you or book a call.
Missing search terms
If you are a "growth lead" but people search for "performance marketing", you will not show up. Use the words your audience uses.
Written for the wrong reader
A profile aimed at recruiters puts off clients, and the other way round. Decide who the profile is for, then write for them.
LinkedIn profile character limits
| Field | Limit | What to do with it |
|---|---|---|
| Headline | 220 characters | Put the words people search for first. Only the start shows next to your name in feeds and comments. |
| About | 2,600 characters | Use the first two or three lines as a hook. Everything after them is behind "see more". |
| Job title | 100 characters | Use the title people search for, not only your internal one. |
| Custom profile URL | 3 to 100 characters | Claim linkedin.com/in/yourname so the link looks clean on a CV or email signature. |
Post on LinkedIn without writing everything twice
A strong profile gets visits. Recent posts are what turn those visits into connections. MicroPoster publishes what you already write on X, Threads, Bluesky or Mastodon to LinkedIn as a native post, so your profile never looks abandoned.

Frequently asked questions
What is a good LinkedIn profile score?
Above 75 means a stranger quickly understands what you do and who it is for, and the right search terms are there. Between 50 and 75 is a decent profile with clear gaps. Below 50 usually means a title-only headline or an empty About section, which are quick to fix.
Why do I paste my profile instead of entering a URL?
LinkedIn does not let other apps read a member's profile, and we do not scrape it. Pasting takes ten seconds: open your profile, copy the headline and the About text, and paste them in.
Is what I paste saved?
No. Your text is sent to an AI model to write the review and is not stored by MicroPoster. Nothing is posted to LinkedIn and you do not need an account.
Which parts are AI and which are rules?
The profile setup score uses fixed rules: headline length, whether the headline is only a job title, the length of your About section, whether it ends with a way to reach you, and stock phrases. The headline, About and searchability scores, the rewrites and the keyword suggestions come from an AI model that is told never to invent employers, numbers or credentials.
Is it free?
Yes. Three reviews a day, no account and no credit card.
Does it look at my experience, skills or photo?
Not yet. It focuses on the headline and About section because they are what strangers read first and what you can improve in a few minutes. Keep your job titles in the words people search for and add skills that match the keywords it suggests.
