LinkedIn Profile Optimization: A Practical Checklist

Go section by section with LinkedIn’s own specifications and steps, from your photo and headline to Featured, skills and recommendations.

In short: use a clear photo of at least 400 × 400 px and a 1584 × 396 px cover image, write a headline that says your role, who you help and your specialism (it shows in search results), set a custom URL, write an About section with proof and a call to action, feature your best work, list relevant skills (up to 100), ask for recent recommendations and add a free verification if eligible.

Why your LinkedIn profile matters

Your LinkedIn profile is often the first thing a prospect, recruiter, investor or partner checks after seeing your name. It works like a landing page: in a few seconds the visitor decides whether you are relevant, credible and worth contacting.

This checklist goes section by section, from the top of the profile down, with the steps and specifications LinkedIn publishes in its Help Center. LinkedIn changes its interface often, so if a button has moved, the linked Help page has the current steps. We don’t quote profile-view statistics here; measure your own results in LinkedIn’s profile analytics before and after you make changes.

The 10-minute checklist

  • Profile photo: clear, recent, your face, at least 400 × 400 px.
  • Cover image: 1584 × 396 px, saying what you do or who you help.
  • Headline: role + who you help + outcome, in plain words people search for.
  • Custom public URL: a variation of your name.
  • About: who you help, how, proof, and how to contact you.
  • Featured: your best post, case study or offer.
  • Experience: outcomes, not just duties, for each recent role.
  • Skills: the skills you want to be found for, kept relevant.
  • Recommendations: two or three recent ones from clients or managers.
  • Verification: add a free verification if you are eligible.

Details for each item follow.

1. Profile photo and cover image

LinkedIn’s page on photos that won’t upload gives the specifications:

ImageLinkedIn’s specification
Profile photoBetween 400 × 400 and 7680 × 4320 px; PNG or JPG; max 8 MB; GIFs not supported
Cover (background) image1584 × 396 px recommended; JPG or PNG; under 8 MB

From LinkedIn Help: Photo won’t upload to your profile and Add or change the cover image on your profile. See all platforms in our social media image size guide.

LinkedIn says your profile photo must reflect your likeness; an illustration is allowed if it looks like you. Choose a well-lit photo where your face fills most of the frame. For the cover image, keep text short and away from the lower left, where your profile photo overlaps it. LinkedIn notes that photos tend to look better than images with logos, and that a blurry cover is usually fixed with a larger, higher-quality file.

For banner layout and the area your photo covers, see our LinkedIn banner size guide.

2. Headline: the most important line

LinkedIn’s Help page on editing your headline says the headline is the text below your name, is displayed in search results, and can be different from your current job title. Edit it from the Edit (pencil) icon in your introduction section.

A practical formula is Role | Who you help | Result or specialism:

  • Weak: “Founder at Acme”
  • Better: “Founder, Acme | Payroll software for UK restaurants | Cut payroll time”
  • Weak: “Looking for opportunities”
  • Better: “Data Analyst | SQL, Power BI | Retail and e-commerce analytics”

Use words your buyers or recruiters would actually type. LinkedIn doesn’t state a headline character limit on that Help page, so we don’t quote one; the edit box will stop you if you go over.

Stuck for wording? Our free LinkedIn headline generator turns your role, skills and results into options you can edit.

3. Custom public profile URL

LinkedIn’s page on managing your public profile URL says you can customise the last part of your URL from Public profile & URL on your profile. Its rules:

  • 3 to 100 characters, with no spaces, symbols, special characters or the word “LinkedIn”.
  • Case doesn’t matter, and custom URLs are first come, first served.
  • You can change it up to five times in six months; after the fifth change you have to wait six months.

LinkedIn recommends a variation of your name or professional brand. Add the URL to your email signature, website and CV.

4. About section

About is part of the Core sections you add through Add profile section (LinkedIn Help: Add sections to your profile). Write it in the first person, for the reader you want:

  1. Opening line: who you help and the problem you solve.
  2. How: your approach, services or specialisms in two or three short lines.
  3. Proof: named clients (with permission), results, awards or credentials you can back up.
  4. Call to action: how to contact you, for example “Message me here or book via the link in Featured”.

Keep paragraphs short; most people read on a phone. Draft it in our character counter so you can see its length as you edit.

5. Featured, Experience and Skills

Featured. LinkedIn’s page on featured samples of your work says you can feature posts you have created or re-shared, articles you published on LinkedIn, links to external websites and uploaded media such as images, documents, presentations and videos. Add your strongest case study, a lead magnet, a popular post or a short intro video.

Experience. For each recent role, add two to four lines on outcomes: what changed because you were there. Add media or links where they prove the point.

Skills. LinkedIn says you can add up to 100 skills, and that a relevant list helps others understand your strengths and match you with opportunities (Add and remove skills on your profile). Prioritise the skills you want to be found for and remove outdated ones.

6. Recommendations and verification

Recommendations. LinkedIn lets you request a recommendation from a connection’s profile (More, then Request a recommendation) or from the Recommendations section of your own profile. You choose the relationship and your position at the time, and can personalise the message. LinkedIn notes that recommendations can only be requested in your primary profile language. Ask recent clients or managers, and suggest what to mention, such as a specific project.

Verification. LinkedIn’s page on verifications on your LinkedIn profile says you can currently verify your identity, workplace or educational institution, that verification is optional and has no additional cost, and that availability depends on the type of verification and where you are. A verified badge appears next to your name for signed-in members.

Open to Work (job seekers). LinkedIn’s Open to Work setting lets you choose whether all members, recruiters only or only you can see your job preferences. LinkedIn says it takes steps to hide this from recruiters at your current company but can’t guarantee complete privacy.

Step-by-step instructions for each method, including DigiLocker in India and work email codes, are in our LinkedIn verification guide.

7. Keep the profile active

A strong profile gets more attention when people see you posting. Share useful posts regularly: lessons from your work, short case studies, opinions on industry news and answers to common customer questions. LinkedIn’s post limit is 3,000 characters, which you can check in our social media character counter.

  • Plan a month of topics with our content calendar generator.
  • Pin your best post to Featured and update it every quarter.
  • Reply to comments on your posts and leave thoughtful comments on others’.
  • Check that your public profile settings show the sections you want people outside LinkedIn to see (Control your public LinkedIn profile).

When you post, use your own analytics to pick the slot: see our guide to the best time to post on LinkedIn.

Personal profile vs Company Page

This checklist is for personal profiles. For a business, your Company Page and your founders’ or employees’ personal profiles do different jobs:

  • Personal profiles carry trust and conversation, which suits opinions, lessons and behind-the-scenes posts from founders and leaders.
  • The Company Page is the official home for jobs, product news, events and company updates, and it is where employees link their experience.

Align both: the same positioning in the founder’s headline and the Company Page tagline, consistent visuals, and regular cross-sharing. Use our image size guide for page images.

Setting up the Page itself? Follow our LinkedIn Company Page optimization checklist.

Common LinkedIn profile mistakes

  • A headline that only says your job title. It wastes the line LinkedIn shows in search results.
  • No cover image, or one with tiny text that is unreadable on a phone.
  • An About section written in the third person like a press release.
  • Old or irrelevant skills listed above the ones you want to be found for.
  • No proof: no Featured items, no results under Experience and no recommendations.
  • Changing the custom URL too often, which LinkedIn warns can make you harder to find.
  • A perfect profile with no activity. Visitors notice when the last post was a year ago.
