How to Build a Network on LinkedIn During Your Job Search

Building a network online is essential, but it is by no means easy!

When you are looking for work, LinkedIn is one of the few places where you can reach almost anyone in your field directly. The challenge is that it does not work the way in person networking does. There is no body language, no shared coffee, and no easy small talk to break the ice. Instead, you are building relationships through profiles, comments, and short written messages.

That actually plays to your advantage, especially if face to face networking drains you (if that sounds like you, our companion post, How to Network for a Job When You’re an Introvert, covers the mindset and energy side in more detail). This guide is about the tactical side: how to set up your profile, get on people’s radar, and grow a network of useful connections on the platform itself.

Here is the arc to follow: get your profile right, warm people up by engaging with their posts, reconnect with people you already know, and then expand outward by adding new people thoughtfully.

Step 1: Fix Your Profile Before You Reach Out

Every time you comment, message, or send a connection request, people click your profile to decide whether you are worth their time. If your profile is outdated or sparse, you lose them before the conversation starts. Treat this as the foundation for everything else.

Focus on the parts that matter most:

•  A clear, friendly headshot and a readable headline that says what you do (not just “Open to Work”).

•  A short “About” section written in the first person that explains your experience and what you are looking for.

•  An experience section with a few concrete accomplishments under each role, not just job titles.

•  The “Open to Work” setting turned on (you can make it visible to recruiters only if you would rather be discreet).

You do not need a perfect profile, just one that looks current and makes a stranger comfortable replying to you.

Step 2: Warm People Up by Commenting on Their Posts

This is the step most people skip, and it is the one that makes everything else easier. Before you ever send a message or a connection request, you can get on someone’s radar simply by engaging with what they share. By the time you do reach out, your name already looks familiar.

Comment with substance, not just praise

A comment that says “Great post!” does nothing. A comment that adds a thought, asks a genuine question, or shares a brief related experience gets noticed (both by the author and by other people reading). Aim for one or two sentences that show you actually read the post.

Be consistent with a small group

Pick a handful of people whose work matters to your search (hiring managers, leaders at target companies, peers in your field) and engage with their posts regularly over a few weeks. Familiarity builds quietly, and a connection request from someone who has been thoughtfully commenting is far more likely to be accepted.

Post occasionally yourself

You do not have to become a content creator, but sharing the occasional update (an article you found useful, a reflection on your field, a note that you are exploring new roles) keeps you visible in other people’s feeds and gives your connections a reason to reach back out to you.

Step 3: Reconnect With Past Coworkers

The warmest connections you have are people you have already worked with. They know your work, they are usually happy to hear from you, and they are often the ones who pass along referrals. The hard part is breaking the silence after months or years, so keep it simple and genuine.

Acknowledge the gap, then get to the point

There is no need to apologize for being out of touch. A short message works best: note that it has been a while, mention something you genuinely remember about working together, and explain that you are exploring new opportunities. Most people respond warmly to a sincere, low pressure note.

Make a specific, easy ask

Vague requests are hard to answer. Instead of “let me know if you hear of anything,” try something concrete: ask whether they would be open to a fifteen minute catch up call, or whether they know how things look at a particular company you are targeting. A clear, small ask is easy to say yes to.

Reconnect before you need something

If you can, send a friendly message before you have a specific request (congratulating them on a new role, for example). It makes the later conversation feel natural rather than transactional, though a direct reach out during your search is still completely reasonable.

People are always looking for connection. Don't be afraid to reach out to past acquaintances (even if it feels awkward!)

Step 4: Add New People Thoughtfully

Once your profile is solid and you are engaging regularly, you can start expanding your network to people you do not yet know. This is where many job seekers get nervous, but cold adding people on LinkedIn is normal and expected. The key is to be targeted and personal rather than sending requests in bulk.

Target the right people

Focus on people who are relevant to your search: others in your role or industry, employees at companies you would like to work for, recruiters in your field, and people whose posts you have already been engaging with. A smaller network of relevant connections is worth far more than a large random one.

Almost always add a note

A connection request with a short personal note gets accepted far more often than a blank one. You only get a couple of sentences (LinkedIn caps the note at a few hundred characters), so be brief: say why you are reaching out and mention something specific, such as a shared background, a mutual connection, or a post of theirs you appreciated.

Respect the platform’s limits

LinkedIn limits how many connection requests you can send (roughly 100 per week for most accounts), and sending too many at once can get your account temporarily restricted. This is good news for a thoughtful approach: spread your requests out, personalize them, and withdraw old ones that are never accepted to keep your account in good standing.

Do not pitch in the first message

When someone accepts, resist the urge to immediately ask for a job. Open with a thank you and a light, genuine message. Build a little rapport first, then move toward your actual goal once there is a real conversation going. The connection is the start of a relationship, not the finish line.

Time to Build That Network!

Building a network on LinkedIn is less about volume and more about sequence: a current profile, steady engagement, warm reconnections, and targeted new requests with a personal touch. Done in that order, each step makes the next one easier, and none of it requires you to be loud or pushy.

Start today by updating one section of your profile and leaving two thoughtful comments on posts in your field. Small, consistent actions are what turn a quiet LinkedIn presence into a network that actually helps you land your next role.
