What Is LinkedIn? Complete Guide 2025 | Job Hunting, Resume Optimization, and Scam Prevention

Have you ever received a message from a headhunter but didn't know how to respond? Or wanted to change jobs but had no idea where to start? LinkedIn might be exactly what you've been looking for.

This is not a typical job board — it's a professional career networking platform where headhunters come to find you.

This guide answers every question from registration through to successfully landing a job, giving you complete command of LinkedIn.

LinkedIn in Taiwan's Job Market: A Professional Platform with 6 Million Users

Over 6 million people in Taiwan use LinkedIn.

That number is growing rapidly.

Why? Because more and more Taiwanese companies — especially multinationals and startups — are using LinkedIn to find talent. Traditional job boards like 104 and 1111 remain important, but LinkedIn offers a completely different approach.

On 104 or 1111, you actively submit applications.

On LinkedIn, headhunters come to you.

That's the core difference. You stop being just a job seeker and become a professional passively waiting for the right opportunity. With a well-optimized profile and the right keyword placement, recruiters will find you through LinkedIn's search — reaching out directly to ask about your job search status, and sometimes recommending you to employers directly.

But it also means you need to understand how to be "found."

What Is LinkedIn? Why Do You Need It?

LinkedIn's Core Definition

LinkedIn is the world's largest professional career networking platform.

As of 2025, it has over 900 million users globally.

It is not Facebook, Instagram, or Twitter. LinkedIn is focused entirely on "careers." What you share here are professional achievements, industry insights, and expert articles — not travel photos or restaurant check-ins.

Simply put:

• Facebook = life and social
• Instagram = visual sharing
• LinkedIn = career networking

LinkedIn's role in Taiwan is clear: a professional network for working professionals. Whether you're a job seeker, employed professional, entrepreneur, salesperson, or student, LinkedIn provides value.

LinkedIn's 3 Core Values

1. Job Searching and Passive Job Searching (Headhunters Come to You)

This is the primary reason most people use LinkedIn.

On traditional job platforms, you need to:

• Search for jobs
• Write cover letters
• Submit applications
• Wait for responses

On LinkedIn, you can:

• Optimize your profile
• Enable "Open to Work"
• Wait for headhunters to message you

This isn't laziness — it's a smarter approach. With a well-optimized profile, headhunters use LinkedIn's search to find you and proactively ask about your job search intentions, sometimes referring you directly to employers.

2. Career Brand Building (Personal Influence)

LinkedIn lets you build a personal brand.

By publishing articles, sharing industry insights, and participating in discussions, you demonstrate your expertise to your connections, recruiters, and potential employers — gradually building influence in your field.

Imagine: when an HR manager wants to find a "digital marketing expert," they Google the topic and find your LinkedIn article. Your credibility immediately gets a boost.

3. Industry Networking

LinkedIn's core feature is "connection."

You can add other professionals as connections (LinkedIn's term for friends), expanding your network. These connections aren't just numbers — they're real resources:

• Considering a career change? Ask someone who's already in that field
• Want to know a company's culture? Find someone who works there
• Looking for career advice? Reach out to an experienced mentor

Networking is one of the most important assets in career development, and LinkedIn digitalizes and systematizes it.

LinkedIn vs. Traditional Job Boards

The table makes it clear: LinkedIn and traditional job boards are not competitors — they're complementary.

104 and 1111 are best for quickly finding jobs and submitting many applications.

LinkedIn is best for building long-term career brands and waiting for better opportunities.

Smart job seekers use both, adjusting their strategy based on their career stage.

Finding Jobs on LinkedIn: The Complete Approach

The logic of job searching on LinkedIn is completely different from traditional job platforms.

On 104/1111, you find the jobs.

On LinkedIn, jobs find you.

Of course, you can also actively search for roles and apply on LinkedIn — but the greatest value is in "passive job searching": optimize your profile and let recruiters and HR come to you.

Why LinkedIn Is Especially Effective for Job Searching

According to research, over 70% of recruiters use LinkedIn to find candidates.

What does this mean?

If you don't have a LinkedIn account, or your profile isn't optimized, you're missing a massive pool of opportunities. Especially in multinationals, startups, and tech companies — LinkedIn is the primary recruiting channel.

LinkedIn's 3 advantages for job searching:

1. Recruiter Search — Recruiters can search by keyword, industry, and location. If your profile matches, you appear in results.
2. "Jobs You May Like" Recommendations — LinkedIn's algorithm recommends suitable roles based on your profile, skills, and history.
3. Referral and Network Advantage — If you know someone at a target company, you can ask them to refer you — dramatically increasing hiring chances.

LinkedIn Job Search: 7 Steps Overview

For the full detailed guide, see: LinkedIn Job Search Complete Guide 2025.

Here is a summary:

Step 1: Optimize Your Profile (Increase Searchability by 30%)

This is the most important step.

Your LinkedIn profile is a "permanently online resume" that recruiters can find at any moment. Profile completeness, keyword placement, and professional photos are all crucial.

Key elements include:

• Professional profile photo
• Compelling Headline
• Complete About section
• Detailed work experience
• Relevant skills

For full resume writing tips, see: LinkedIn Resume Writing Complete Guide 2025.

Step 2: Use Advanced Search Features

LinkedIn's job search is extremely powerful. You can filter by:

• Job title
• Industry
• Company
• Location
• Years of experience
• Salary range

Even better, you can "Save Searches" — LinkedIn will automatically notify you of new matching jobs.

Step 3: Use the "Open to Work" Feature

When enabled, your photo displays a green border indicating "Open to Work," telling recruiters you're available. You can set it to:

• Visible to recruiters only (so your current employer won't find out)
• Visible to everyone

If you're still employed, the recruiter-only setting is recommended.

Step 4: Timing for Submitting Applications

Research shows Tuesday to Thursday mornings (10:00–11:00 AM) have the highest response rates.

Why? This is when HR has the most time to review applications. Monday is too busy, Friday people are checking out, weekends nobody's in.

Also — always write a customized cover letter rather than using a generic template.

Step 5: Build Your Network as a Job Search Channel

LinkedIn's networking is your greatest asset.

Strategic connection building:

• Add professionals in your target industries
• Add employees at target companies
• Add alumni and former colleagues

When applying to a company, if you have a connection there, politely ask whether they can provide a referral — success rates improve dramatically.

Step 6: Keep Optimizing — Long-Term Management

LinkedIn is not a one-time tool.

Even when you're not looking, regularly update your profile, publish posts, and participate in discussions to stay active. When future opportunities arise, your profile is already ready.

Step 7: Stay Safe — Avoid Scams

LinkedIn also has scammers.

Fake headhunters, fake HR, fake companies all exist. How to identify them? See our full prevention guide: LinkedIn Scam Prevention Guide 2025.

LinkedIn Resume Writing Guide

LinkedIn resumes are fundamentally different from traditional resumes.

A traditional resume is written for HR to read.

A LinkedIn resume is written for a search engine to index.

What does this mean? LinkedIn has a search algorithm that recruiters use with keywords. If your resume doesn't include the right keywords, you won't appear in search results — no matter how qualified you are.

LinkedIn Resume vs. Traditional Resume

Key Section Optimization Tips (Overview)

This is a summary only — for full writing techniques, examples, and templates, see: LinkedIn Resume Writing Complete Guide 2025.

Section 1: Profile Photo

Photos matter enormously.

Profiles with photos are clicked 14x more often.

But not just any photo. A LinkedIn photo should be:

• Professional (business casual or formal attire)
• Clear (high resolution, good lighting)
• Simple background (avoid clutter)
• Face clearly visible (smiling, eye contact)

Selfies, travel photos, and avatar images are not appropriate.

Section 2: Headline Optimization

Your Headline is your "career tagline" — only 120 characters, but critically important.

Bad example: "Marketing Specialist"

Good example: "Digital Marketing Specialist | SEO/SEM Expert | Helped 10+ Brands Increase Traffic by 200%"

See the difference? A good Headline includes:

• Job title
• Area of expertise
• Quantified achievement

Section 3: About / Summary

The About section is the most important block — you have 2,600 characters to work with.

Don't just list work history — tell a story:

• Who are you?
• What do you do?
• What are your strengths?
• What value can you provide?

Use the WHY-HOW-WHAT framework:

1. WHY — Why did you choose this career path?
2. HOW — How do you achieve results?
3. WHAT — What value / services can you offer?

Section 4: Work Experience

Work experience is not a task list — it's an achievements showcase.

Use the STAR method:

• Situation
• Task
• Action
• Result

Example: "Managed company social media" → too vague

"Over 6 months, through content strategy and paid advertising, grew Instagram following from 5,000 to 50,000, increased engagement rate by 300%, and generated NT$1,000,000 in revenue" → specific and compelling

Section 5: Skills and Certifications

LinkedIn allows up to 50 skills.

But quality matters more than quantity — especially the top 3 skills, which appear in search results and determine whether you get found.

When selecting:

• Is this a core strength?
• Will recruiters search this keyword?

Certifications are equally important. If you have Google Ads certification, PMP, or language proficiency scores — add them to boost credibility.

LinkedIn Scam Prevention: Complete Guide

Are there scams on LinkedIn?

Yes — and there are quite a few.

As LinkedIn grows in Taiwan, scammers have moved in too. They impersonate recruiters, HR managers, and investment advisors — attempting to steal your personal data, your money, or draw you into pyramid schemes.

Common LinkedIn Scam Tactics (Overview)

For full scam tactic breakdowns, real case studies, and reporting procedures, see: LinkedIn Scam Prevention Guide 2025.

1. Fake Recruiter / Headhunter Scam

Scammers impersonate recruiters and tell you about a high-paying opportunity — but require you to:

• Pay a "background check fee" upfront
• Provide credit card information
• Transfer a "training fee"

Legitimate recruiters never ask you for money. If anyone does, it's 100% a scam.

2. Fake HR Scam

Scammers pose as HR from a well-known company and invite you for an interview — but the location is suspicious (not the company's office), or they ask you to pay a document processing fee upfront.

How to verify: call the company's main reception line directly and ask whether they have an HR by that name and whether they truly sent you an interview invitation.

3. Investment and MLM Scams

Someone adds you on LinkedIn, chats for a bit, then starts recommending "guaranteed investment opportunities" or "business ventures."

This typically involves cryptocurrency, forex trading, or health product MLM schemes.

LinkedIn is a professional career platform, not an investment platform. Anyone proactively pitching you investments deserves serious skepticism.

How to Identify Scam Accounts: 5 Standards

1. Low profile completeness — no photo, few work entries, very few connections
2. Poor-quality connections — all their connections look suspicious too
3. Urgent-sounding messages — "limited time opportunity," "decide now"
4. Requests for money or personal data — legitimate job offers never require upfront payment
5. Company information can't be verified — can't find the company on Google, or company information is suspicious

LinkedIn Account Verification

When registering or using LinkedIn, you may encounter verification requirements.

Why is verification needed?

To confirm you're a real person and not a bot or scam account. Verification enhances account security and unlocks full functionality.

4 Verification Methods

Method 1: Phone Verification (Most Common)

The simplest method. LinkedIn sends a verification code via SMS — enter it and you're done.

But some users encounter "didn't receive the code" issues. Possible causes:

• Incorrect phone number format
• SMS blocked
• Carrier issues
• Phone settings

Method 2: Email Verification

LinkedIn sends a verification email. Click the link inside to complete verification.

Remember to check your spam folder — verification emails sometimes get misclassified.

Method 3: Persona Identity Verification (Advanced)

If your account is locked or requires advanced verification, LinkedIn may ask for Persona verification — uploading an identity document (passport, driver's license, national ID) for manual review by Persona, a third-party verification company.

Method 4: Work Email Verification

If you registered with a company email, LinkedIn automatically verifies your company affiliation, increasing profile credibility.

10 Must-Know LinkedIn Features for Beginners

LinkedIn is far more than a job-finding tool.

It has many practical features that help you build your career brand, expand your network, and learn new skills.

Here are 10 essential features for beginners:

Basic Features

1. How to Register and Set Up Your Profile

Registration is straightforward:

1. Go to LinkedIn.com
2. Enter your email and password
3. Fill in basic information (name, location, industry, job title)
4. Complete verification

After registering, immediately optimize your profile. The more complete it is, the higher your search visibility.

2. Full Privacy Settings Check

LinkedIn is public by default, but you can adjust privacy settings:

• Who can see your profile?
• Who can see your connections?
• Should others know when you browse their profile?

Go to "Settings & Privacy" → "Privacy" to adjust.

3. Notification Management

LinkedIn sends a lot of notifications, which can become overwhelming.

Recommended: turn off less important ones and keep only:

• New job opportunity alerts
• Someone sent you a message
• Someone viewed your profile

This reduces distractions and keeps you focused on what matters.

Advanced Features

4. Who Viewed Your Profile

One of LinkedIn's most useful features.

You can see who has browsed your profile. If it's a headhunter or HR from a target company, you can proactively send a message — creating an opportunity.

The free version only shows the last 5 visitors with limited information. To see the full list, you need to upgrade to Premium.

For a full feature breakdown, see: LinkedIn Who Viewed My Profile Tutorial.

5. LinkedIn Search (SOLI)

This is LinkedIn's internal SEO.

SOLI stands for Search on LinkedIn Index — your profile's ranking in LinkedIn's internal search. Ways to improve your ranking include:

• Complete your profile fully
• Add relevant keywords
• Obtain skill endorsements
• Collect profile recommendations

6. Is LinkedIn Premium Worth It?

LinkedIn Premium is a paid subscription offering more features:

• Full "Who viewed your profile" list
• InMail (message people who aren't connections)
• More job application insights

Is it worth subscribing? Depends on your needs. If you're actively job hunting, Premium may help. If you're a casual user, the free version is sufficient.

An online course platform built into LinkedIn.

Over 20,000 courses covering programming, marketing, project management, data analysis, and more. Premium subscribers get unlimited access. Courses come with completion certificates you can display on your profile.

Designed for B2B salespeople, it offers advanced lead search, real-time tracking, and up to 50 InMail messages per month. It's the most powerful tool on LinkedIn for active sales outreach.

Built for HR and talent acquisition teams — enables advanced candidate search, project management, and collaborative hiring workflows.

10. LinkedIn Events and Groups

• Events: Online and in-person industry events for networking and learning
• Groups: Industry communities for discussions, insights, and hidden job opportunities

LinkedIn FAQ: Quick Answers

Q1: Is LinkedIn in Chinese or English?

LinkedIn's interface supports Traditional Chinese, but content language depends on each user.

For resumes, bilingual (Chinese + English) is recommended:

• Chinese makes it easier for Taiwanese HR to read
• English ensures multinational headhunters can find you

Q2: Do you have to pay to use LinkedIn?

Not necessarily.

The free version includes most features and is sufficient for most job seekers. Premium makes sense for people who need advanced tools — such as salespeople, recruiters, and senior executives.

Q3: Is LinkedIn really effective for finding work?

Very — especially in multinationals, tech, and startups.

According to surveys, over 70% of headhunters use LinkedIn to find candidates. If those are your target industries, LinkedIn is essential.

If your target is traditional industries (manufacturing, basic services), 104 or 1111 may be more effective.

Q4: How detailed should a LinkedIn resume be?

The more detailed, the better — but maintain readability.

Don't just list duties — emphasize results:

• Bad: "Responsible for marketing activities"
• Good: "Planned 5 marketing campaigns generating NT$5,000,000 in revenue with a 300% ROI"

Q5: How do I avoid my current employer finding out I'm job searching?

If you're still employed but exploring options:

• Set "Open to Work" to "Recruiters only"
• Turn off "Notify network of profile changes" (so your employer doesn't see frequent updates)
• When messaging about job opportunities, use LinkedIn messages — not your company email

Q6: Does your connection count matter?

Quality over quantity.

Having 500+ connections looks professional, but if they're all strangers, it's meaningless. Prioritize:

• Professionals in your industry
• Employees at target companies
• Alumni and former colleagues

Q7: Do you need to post regularly on LinkedIn?

Not necessarily, but it helps.

Posting increases your visibility and demonstrates expertise. But don't post for the sake of posting — content needs to add value. 1–2 posts per week is enough.

Q8: How do you spot LinkedIn scams?

5 quick identification standards:

1. Low profile completeness
2. Very few connections
3. Message requests money or personal data
4. Company information unverifiable
5. Messages full of urgency and pressure
