LinkedIn: The giant of professional networking
What exactly is LinkedIn?
Launched in 2003 in San Francisco, LinkedIn is the world's largest professional social network. With millions of LinkedIn members in over 200 countries, it brings everyone together: students, freelancers, entrepreneurs, recruiters, and even CEOs of large companies. Unlike other social networking apps such as Instagram or TikTok, LinkedIn is 100% dedicated to business. Here, we talk about career opportunities, business connections, job hunting, and industry news.
But LinkedIn isn't just an online resume. It's a vibrant platform where you can search for companies, apply for jobs, share professional content, and learn with exclusive tools. Whether you're looking for a part-time job, your dream position, or business insights, LinkedIn opens doors for you.
Why is everyone on LinkedIn?
In a world where connections matter as much as skills, LinkedIn is a must for professionals. It's where you can introduce yourself to recruiters, connect with business contacts, and showcase your expertise. Companies spend hours searching for potential candidates, and a well-crafted LinkedIn profile can make you stand out from the crowd. Plus, it's a hub for staying informed about industry buzz and newsworthy stories.

Features that make LinkedIn a must
Your LinkedIn profile: Your professional showcase
Your LinkedIn profile is your online resume, but better. You can list your skills, professional experience, education, and even add projects, certifications, or portfolios. Recruiters love this because a well-filled profile gives them a complete picture of your expertise. But LinkedIn goes further: you can show your personality by publishing posts, collaborative articles, or interacting with top voices, the influencers who are creating buzz on the platform.
An optimized professional profile is also a magnet for professional connections. By sharing relevant content, you get noticed by the LinkedIn community and increase your chances of being spotted for new job opportunities.
Job search: Find the job of your dreams
LinkedIn is a goldmine for job seekers. With millions of career opportunities posted every month, you can filter by industry, location, experience level, or even job responsibilities. The “simplified application” feature lets you submit applications in just a few clicks, and job alerts send you notifications when a job matches your criteria.
If you want to go further, LinkedIn's premium subscription gives you access to exclusive tools: InMails to contact recruiters directly, candidate statistics, and even courses via LinkedIn Learning. This gives you a serious advantage in securing interviews and standing out from the crowd.
The LinkedIn app: Your network at your fingertips
The LinkedIn app, available on iOS and Android, is super handy for staying connected on the go. Here are some of the features of the LinkedIn app:
Check out the latest business news and catch the industry buzz.
Manage your professional network by adding business contacts or sending connection requests.
Receive notifications about your posts, interactions, or new job opportunities.

The app is secure, requires few permissions (just access to your address book if you want to import contacts), and protects your collected data by only sharing it with trusted partners. You can apply with confidence thanks to options such as secure application.

Advanced strategies for dominating LinkedIn

Build a strategic network
Networking on LinkedIn is an art form. Forget about sending out connection requests en masse. Target professionals in your industry or business contacts who can open doors for you. Personalize each request with a short message, such as: “Hi [First name], I was really inspired by your post on [topic] and would love to chat!”
Once connected, engage: like, comment, and share their posts. This strengthens your relationships and makes you visible in their network.
Create content that makes an impression
To stand out, create content that adds value. Here are a few ideas:
Write collaborative articles on current topics in your industry.
Post selfie videos to share a professional anecdote or piece of advice.
Comment on posts from top voices with relevant remarks.

Use LinkedIn events
LinkedIn also offers virtual and in-person events. Participate in webinars, conferences, or roundtable discussions to expand your network and catch up on the latest business news. It's also an opportunity to connect with industry experts.
