LinkedIn: What It Is, How It Works, and How to Use It

Introduction

LinkedIn is a professional networking platform that helps people connect, find jobs, and grow their careers. It also helps businesses promote their services and meet new customers.

You can use LinkedIn to build a professional profile, follow companies, contact recruiters, and share your work. It is useful for students, job seekers, freelancers, business owners, and people who want to learn new skills.

For people in the UK, LinkedIn can be a helpful way to explore local jobs, meet professionals, and learn about different industries. You can start with a free account and use many of its main features without paying.

This guide explains what LinkedIn is, how it works, and how to use it. You will also learn how to create a strong profile, search for UK jobs, build useful connections, and use LinkedIn for business.

What Is LinkedIn?

LinkedIn is an online platform for professional networking. It allows people to create work profiles, connect with others, share ideas, and explore career opportunities.

It was launched in May 2003. Microsoft bought LinkedIn in 2016. Today, it is part of Microsoft’s group of services.

The main aim of LinkedIn is to help people build professional relationships. It is different from platforms that focus mainly on personal photos, entertainment, or daily life updates.

On LinkedIn, users often share:

• Work experience and career updates.
• New skills and certificates.
• Business news and company updates.
• Job openings and career advice.
• Articles and useful ideas.
• Projects and examples of their work.

For example, a marketing assistant in Manchester can use LinkedIn to connect with other marketers. A student in London can follow employers and look for graduate jobs. A small business owner in Birmingham can use it to promote services and meet potential customers.

In simple terms, LinkedIn is a place where people and businesses can build a professional presence online.

How Does LinkedIn Work?

LinkedIn works through personal profiles, connections, posts, company pages, and job listings.

You first create an account and add details about your work, education, and skills. Then you can connect with people, follow companies, and take part in professional discussions.

Here is how the platform works.

1. Create a Personal Account

Start by signing up with your email address or another sign-up method offered by LinkedIn. You then add basic details, such as your name and location.

2. Build Your Professional Profile

Your profile acts like an online CV. It can show your work history, education, skills, projects, and career goals.

3. Connect With Other People

You can send connection requests to colleagues, classmates, recruiters, and people in your industry. When someone accepts your request, you become part of each other’s network.

4. Follow People and Companies

You can follow a company or professional to see their public updates. Following does not always require a connection request.

5. Share Posts and Updates

LinkedIn allows members to share text, images, videos, documents, and other content where these options are available.

For example, you could share a project you have completed or a lesson you learned during a course.

6. Search for Jobs

The Jobs section helps you find vacancies by job title, company, location, and other filters. You can also save suitable jobs and set alerts.

7. Join Professional Conversations

You can comment on posts, ask useful questions, and share your views. This helps you take part in discussions with people who work in your field.

8. Learn New Skills

LinkedIn also offers learning content through LinkedIn Learning. Access to courses depends on the service or subscription available to you.

These activities help you build a professional presence and stay connected with your industry.

What Is LinkedIn Used For?

LinkedIn has several uses. You do not need to be looking for a job to benefit from it.

Here are some common ways people use the platform.

Finding Jobs

Job seekers can search for vacancies, follow employers, and connect with recruiters. They can also learn about companies before applying.

For example, someone looking for a customer service role in Leeds can search for that job title and choose Leeds as the location.

Building Professional Connections

LinkedIn helps people meet others who work in the same field. These connections may share advice, news, or useful opportunities.

Developing a Career

You can follow industry experts, learn about new skills, and see what employers look for in different roles.

Promoting a Business

Businesses can create a Company Page and share news, services, products, and useful information.

Finding Potential Clients

Freelancers and agencies can use LinkedIn to find businesses that may need their services. They can build relationships before discussing paid work.

Recruiting Employees

Employers can share job posts and look for people with the skills they need. Some recruitment tools require paid access.

Sharing Professional Knowledge

People can publish helpful posts, explain ideas, and discuss changes in their industry.

Learning New Skills

Users can explore courses and other learning resources. Topics may include marketing, business, technology, communication, and management.

Following Industry News

You can follow companies and professionals to keep up with news and changes in your field.

How to Create a LinkedIn Account

Creating a LinkedIn account is simple. You can sign up through the website or mobile app.

Follow these steps:

1. Visit the official LinkedIn website.
2. Select the sign-up option.
3. Enter the details requested by LinkedIn.
4. Verify your email address or phone number if asked.
5. Add your name and location.
6. Choose relevant work or career interests if prompted.
7. Add basic details to your profile.
8. Upload a clear profile photo.
9. Start connecting with people you know or who work in your field.

The exact sign-up steps may change as LinkedIn updates its website and app.

Tip: Use an email address that you can access. Keep your login details private and choose a strong password.

How to Create a Professional LinkedIn Profile

A good LinkedIn profile helps people understand who you are and what you do. It can also make it easier for recruiters, clients, and other professionals to find you.

You do not need years of work experience to create a useful profile. Students and beginners can include their education, skills, projects, and career interests.

Profile Photo

Your profile photo is one of the first things people may notice.

For a professional look:

• Use a clear photo of yourself.
• Choose a simple background.
• Make sure your face is easy to see.
• Use good lighting.
• Avoid heavy filters and unclear images.

You do not need an expensive camera. A clear photo taken with a mobile phone can be enough.

Profile Headline

Your headline appears near your name. It tells people what you do or what type of work you want.

Avoid using only a general phrase such as “Looking for opportunities”. Instead, describe your skills or career direction.

Here are some examples:

For a job seeker:

“Marketing Graduate | Interested in Digital Marketing and Content Creation”

For a freelancer:

“Freelance Graphic Designer | Logo Design and Brand Visuals”

For a business owner:

“Founder | Helping Small Businesses Improve Their Online Presence”

Keep your headline clear and honest. Do not claim skills or results that you cannot support.

About Section

The About section gives you space to explain your background, skills, and goals.

A useful About section should answer three simple questions:

• Who are you?
• What skills or experience do you have?
• What type of work or professional opportunities interest you?

For example:

“I am an aspiring digital marketer with an interest in SEO, content writing, and online business growth. I enjoy learning new tools and working on practical projects. I am keen to connect with professionals and businesses in the digital marketing industry.”

Write in your own voice. Keep it easy to read and avoid making claims that are not true.

Work Experience

Add your current and past jobs where relevant. Include the company name, job title, dates, and main duties.

Try to explain what you did rather than only listing your job title.

For example, a marketing assistant could write:

• Helped prepare social media posts.
• Supported basic keyword research.
• Updated website content.
• Assisted with marketing reports.

If you are new to work, you can add internships, volunteer roles, and suitable projects.

Education

Add your school, college, university, or other learning provider. Include your qualification and the dates if you wish.

You can also add relevant courses and training.

Skills and Recommendations

The Skills section shows what you can do. Add skills that match your experience and career goals.

For example, a web developer may add:

• HTML
• CSS
• JavaScript
• WordPress
• Problem-solving

LinkedIn may allow other members to endorse your skills. An endorsement is a simple way for a connection to support a skill shown on your profile.

Recommendations are different. They are written comments from people who have worked or studied with you. Ask for genuine feedback from people who know your work.

Featured Section

The Featured section can help you show examples of your work.

Depending on the options available to your account, you may be able to highlight:

• Projects.
• Articles and posts.
• Certificates.
• Presentations.
• Work samples.
• Links to websites or portfolios.

Choose items that support the type of work you want to do.

How to Find Jobs on LinkedIn in the UK

LinkedIn Jobs can help you explore vacancies across the UK. You can search for full-time, part-time, remote, hybrid, and office-based roles.

Follow these steps to get started.

Step 1: Open the Jobs Section

Sign in to LinkedIn and select the Jobs section. You can use the website or mobile app.

Step 2: Enter a Job Title

Type the role you want to find.

For example:

• Marketing Assistant.
• Software Developer.
• Customer Service Adviser.
• Finance Assistant.
• Graphic Designer.
• SEO Executive.

Use clear job titles. You can try different words if your first search gives few results.

Step 3: Choose a Location

Enter a UK city or area, such as:

• London.
• Manchester.
• Birmingham.
• Leeds.
• Bristol.
• Glasgow.

You can also explore remote roles if you want to work from home.

Step 4: Use Search Filters

Filters help you narrow your results. Depending on the search, you may be able to choose:

• Date posted.
• Experience level.
• Job type.
• Workplace type.
• Company.
• Location.
• Salary range, where shown.

For example, you could search for entry-level marketing jobs in Manchester that were posted in the past week.

Step 5: Read the Job Description

Check the duties, skills, experience, location, and working hours. Make sure the role matches what you are looking for.

Also check the company website when possible.

Step 6: Apply for the Job

Some employers allow you to apply through LinkedIn. Others send you to their own website.

Follow the instructions and provide the details requested. Check your CV and application before submitting them.

Step 7: Save Jobs

If you find a suitable role but are not ready to apply, save it. This makes it easier to return to it later.

Step 8: Set Job Alerts

Job alerts can tell you when new roles match your search. You can use them to keep track of new vacancies.

Review your alerts from time to time. Change the job title or location if the results are not useful.

Step 9: Use Open to Work

The Open to Work feature lets you show that you are interested in new roles.

You may be able to share this with all LinkedIn members or limit visibility to recruiters, depending on the options shown.

Remember that privacy cannot be guaranteed in every situation. Choose the setting that suits your needs.

Important safety tip: Check that the employer and job are genuine before sharing personal details. Never pay an upfront fee to secure a job. Be careful if someone asks for your bank details, identity documents, or money before you have a genuine job offer.

How to Build a Professional Network on LinkedIn

A LinkedIn connection is a person who has accepted your connection request. Your network can include colleagues, classmates, clients, recruiters, and other professionals.

Building a useful network is about making real professional relationships. It is not just about collecting a large number of connections.

Find People in Your Industry

Use the search bar to look for people by name, job title, company, or industry.

For example, if you work in digital marketing, you could search for:

• SEO specialists.
• Content writers.
• Marketing managers.
• Digital marketing agencies.
• Business owners.

Send a Connection Request

When you find someone relevant, you can send a connection request.

If the option is available, add a short personal message. Explain why you want to connect.

Use a Polite Connection Message

Here is a simple example:

“Hello, I came across your profile while learning more about digital marketing. I am interested in this field and would be pleased to connect and learn from your professional updates. Thank you.”

Keep your message short and respectful. Avoid sending the same sales pitch to everyone.

Reconnect With People You Know

You can connect with former colleagues, classmates, teachers, and people you have worked with.

These relationships may help you learn about new roles, projects, and industry changes.

Follow Industry Experts

You can follow people who share useful advice in your field. Their posts may help you understand new ideas and trends.

Take Part in Discussions

Leave thoughtful comments on posts that relate to your work or interests. Share useful information when you can.

Avoid comments that only ask people to visit your profile or buy your services.

How to Use LinkedIn for Business

LinkedIn is not only for job seekers. It can also help companies, small businesses, agencies, and freelancers build their professional presence.

A business can use LinkedIn to explain what it offers, share updates, and connect with potential customers.

Create a LinkedIn Company Page

A Company Page gives your business a place on LinkedIn.

It can include:

• Business name.
• Logo.
• Website.
• Industry.
• Company size.
• Location.
• About section.
• Products or services, where supported.

Use accurate details and a clear description of your business.

You can learn more through LinkedIn’s official Company Pages information.

Share Company Updates

Post useful updates about your work, services, projects, and news.

For example, a UK web design company could share a website project it has completed. A local accountancy firm could publish a simple guide to preparing business records.

Promote Your Services

Explain the problems your services solve. Use clear examples and helpful information.

Avoid making claims that you cannot prove.

Build Brand Awareness

Brand awareness means helping more people recognise and understand your business.

You can build it by sharing useful content, joining relevant discussions, and keeping your Company Page up to date.

Connect With Potential Customers

Search for businesses and professionals who may need your services. Read their profiles and understand their needs before contacting them.

A useful conversation is often a better starting point than a quick sales message.

Find Business Partners

LinkedIn can help you meet suppliers, agencies, consultants, and other business owners. These connections may lead to useful working relationships.

Recruit Staff

Companies can use LinkedIn to share vacancies and find people with suitable skills. Some recruitment features require paid products.

Publish Useful Industry Content

Share practical advice that helps your audience.

For example:

• A marketing agency could explain basic SEO.
• A finance firm could share simple budgeting tips.
• A software company could explain a common technology problem.

Useful content can help people understand your knowledge and build trust over time.

How Freelancers Can Use LinkedIn to Find Clients

Freelancers can use LinkedIn to show their skills and connect with businesses. It can support client acquisition, but it does not guarantee paid work or income.

The best approach is to build trust and start useful conversations.

Create a Service-Focused Profile

Make it clear what service you provide and who you help.

For example:

“Freelance SEO Specialist | Helping Small Businesses Improve Search Visibility”

Only use this type of headline if it accurately describes your skills and work.

Show Your Skills and Previous Work

Add relevant experience, projects, and work samples. If you have helped a client, explain your role and the work you completed.

Ask for permission before sharing private client information.

Publish Useful Content

Share advice that your target customers may find helpful.

An SEO freelancer could post about:

• Basic keyword research.
• Common website SEO problems.
• On-page SEO tips.
• Content planning.
• Link-building best practices.

Keep your advice clear and useful.

Connect With Relevant Business Owners

Find companies that may need your services. You can search by industry, location, company name, or job title.

For example, a freelance web designer could connect with small business owners who are building their online presence.

Build Relationships Before Pitching

Do not send a sales message as soon as someone accepts your request.

Start with a polite conversation. Read their business profile and look for a genuine reason to connect.

Use Recommendations and Work Samples

Positive feedback from real clients can support your profile. You can also share suitable examples of your work.

Never create fake reviews or claim results that you did not achieve.

What Is LinkedIn Premium?

LinkedIn Premium is a group of paid subscriptions that provide extra tools for different professional needs.

A free LinkedIn account is enough for many basic tasks. However, some users may benefit from extra search, messaging, profile, or business features.

LinkedIn offers different products, so Premium is not one single plan for everyone.

Premium Career

Premium Career is designed for job seekers and people who want to develop their careers.

Depending on the current offer and account, features may include:

• Extra job search insights.
• More information about profile viewers.
• InMail messages to some people outside your network.
• Tools to improve your profile.
• Access to LinkedIn Learning.

Premium Business

Premium Business is aimed at professionals and business owners who want more ways to build their network and explore business information.

It may include extra profile and business insights, along with additional search and messaging tools.

Sales Navigator

Sales Navigator is designed for sales professionals. It helps users find potential customers and manage sales leads.

Its tools can include advanced lead and company searches, saved leads, and sales-related alerts.

Recruiter Products

LinkedIn also offers recruitment products, such as Recruiter Lite. These are designed to help employers and recruiters find suitable people for jobs.

They are different from ordinary personal Premium plans.

Premium Company Page

LinkedIn offers paid features for some Company Pages. These may help businesses improve their page and reach potential customers.

LinkedIn Learning

LinkedIn Learning provides online courses for people who want to build professional skills. Access may be included with some subscriptions or offered separately.

Plan names, features, and availability can change. Check the official LinkedIn Premium information before choosing a subscription.

Is LinkedIn Free?

Yes. You can create and maintain a basic LinkedIn account without paying.

A free account allows you to:

• Create a professional profile.
• Connect with other members.
• Follow people and companies.
• Share posts and updates.
• Search for jobs.
• Apply for jobs where applications are open.
• Send messages within the limits of your account.
• Take part in professional discussions.

Some advanced features require a paid subscription.

For example, extra messaging tools, advanced search options, and certain business insights may be part of paid products.

The cost depends on the plan, billing period, location, and any offer available to your account.

Should beginners pay for LinkedIn?

Most beginners should start with the free account. Build your profile, connect with relevant people, and explore the job or business tools first.

Only consider Premium if you have a clear reason to use its extra features. Check the current UK price and renewal terms before paying.

LinkedIn App: Features and Benefits

The LinkedIn app lets you use the platform on a mobile phone. You can manage your profile, connect with people, search for jobs, and read professional updates while away from your computer.

Common app features include:

View and Update Your Profile

You can edit your headline, About section, work experience, education, and other profile details.

Connect With Professionals

Search for people, review profiles, and send connection requests.

Search and Apply for Jobs

Open the Jobs section to find vacancies. You can also save suitable roles and review job alerts.

Read and Share Posts

View updates from your network and share your own posts. You may also be able to add photos, videos, or documents.

Receive Notifications

The app can notify you about messages, connection requests, comments, and other account activity.

You can manage notifications in your settings.

Manage Messages

Use LinkedIn messaging to talk with your connections and, where available, other members.

Download the LinkedIn app from the official Apple App Store or Google Play Store. Check the app publisher before installing it.

LinkedIn Learning and Professional Development

LinkedIn Learning is an online learning service that offers courses in different work and business subjects.

It can help people develop skills at their own pace.

Courses may cover areas such as:

• Digital marketing.
• Project management.
• Business communication.
• Leadership.
• Software development.
• Data analysis.
• Graphic design.
• Microsoft tools.

How LinkedIn Learning Works

You can browse courses and choose a subject that matches your goals. Some courses are short, while others form part of a longer learning path.

A learning path groups related courses around a topic or skill.

For example, a beginner who wants to work in digital marketing could study courses about SEO, social media, and content planning.

Certificates and Your Profile

Some courses provide certificates of completion. You may be able to add these to your LinkedIn profile.

A certificate can show that you completed a course. However, it does not always prove that you can perform a job to a professional standard.

Try to use what you learn in real projects. Practical work can help you build stronger skills.

Course access and subscription requirements may vary. Check the LinkedIn Learning website for current details.

LinkedIn Safety, Privacy, and Account Security

LinkedIn is a professional platform, but you should still take care when sharing information and talking with people you do not know.

Fake profiles, misleading job offers, and suspicious messages can appear on online platforms.

Use these steps to protect your account.

Use a Strong Password

Choose a password that is hard to guess. Avoid using the same password for several websites.

A password manager can help you create and store strong passwords.

Turn On Two-Step Verification

Two-step verification adds another security step when you sign in.

For example, LinkedIn may ask for a code or another form of confirmation after you enter your password.

This can help protect your account if someone learns your password.

Review Your Privacy Settings

Check who can see your profile details and activity.

You may be able to control settings for:

• Your public profile.
• Your email address.
• Your phone number.
• Your activity and visibility.
• Your profile viewing options.
• Notifications.

The available settings may change. Review them from time to time.

Be Careful With Messages

Do not trust every message you receive. Be cautious if someone sends an unexpected link, asks for money, or requests private information.

Check the sender’s profile and the company they claim to represent.

Watch Out for Fake Job Offers

A suspicious job offer may promise high pay for very little work. It may also ask you to pay for training, equipment, checks, or access to a job.

A genuine employer should not ask you to pay an upfront fee to secure a role.

The UK government’s job search safety guidance advises people not to pay upfront fees for job search help and to protect personal and financial details. You can read its official job search safety advice.

You can also read Report Fraud’s guidance on recruitment scams.

Report Suspicious Profiles and Messages

If you find a fake profile, harmful message, or suspicious job post, use LinkedIn’s report options where available.

Do not send money or sensitive documents while you are unsure whether a person or offer is genuine.

Advantages and Disadvantages of LinkedIn

LinkedIn can be useful for careers and business. However, it also has limits.

It is important to understand both sides before relying on it.

Use LinkedIn with a clear goal. Focus on useful activity rather than spending all day on the platform.

Practical Tips to Get Better Results on LinkedIn

You do not need to use every LinkedIn feature. Start with a few simple habits and improve your profile over time.

11. Avoid false claims: Be honest about your skills, experience, and results.
12. Set a clear goal: Decide whether you are using LinkedIn for jobs, learning, networking, or business.

A small amount of useful activity each week can be more valuable than adding hundreds of random connections.
