How to Build Your LinkedIn Network from Scratch: First Connection Strategy

Everyone who has a strong LinkedIn network started with zero connections. Building from scratch feels slow — but it follows a predictable pattern, and the first hundred connections are the most important to get right.

Here is how to approach it systematically.

Why the First 100 Connections Matter Most

LinkedIn treats profiles with fewer than 100 connections differently from those with more. The platform's search algorithm gives some preference to more connected profiles, and having fewer than 100 connections makes your profile feel less established to visitors.

The other reason the first 100 matter: your early connections define your network's quality. The right 100 connections — people genuinely relevant to your career and sector — are more valuable than 500 random accepts.

Start with Existing Contacts

The fastest and warmest connections you can make are with people you already know:

Former colleagues

Search for everyone you have worked with. Former managers, peers, and reports are all appropriate connections. A connection request with a brief personalised note ("I worked with you at [company] from 2019 to 2021 — would love to stay in touch") takes thirty seconds and is almost always accepted.

University contacts

Former classmates, course mates, society members, and university staff. Search your university's alumni network.

Clients and professional contacts

People you have dealt with professionally outside of your employer — suppliers, clients, collaborators, conference contacts.

Friends who are professional contacts

Not every friend belongs on LinkedIn, but friends who are in your industry or relevant sectors are fair game. The distinction: would you recommend each other professionally?

Importng Contacts

LinkedIn allows you to import contacts from your email address book (Gmail, Outlook, and others). This surfaces people you know who are already on LinkedIn. Use this sparingly and selectively — do not send bulk invitations to everyone in your inbox.

Warm Outreach Strategy

Once you have connected with everyone you know, the next step is warm outreach: people you do not know personally but have a specific reason to connect with.

Alumni from your university at companies you are targeting

LinkedIn's alumni tool (available on your university's page) lets you find graduates who now work at specific companies. A personalised request referencing your shared university is a warm opening.

People you engage with online

If you comment on someone's LinkedIn post and they respond, follow up with a connection request referencing the conversation. This converts a public interaction into a direct connection.

Speakers and attendees at events you have attended

Conference, webinar, and training event organisers often have LinkedIn groups. Connecting with fellow attendees is a natural follow-up.

Recruiters in your sector

Recruiters benefit from a large network — they accept connection requests frequently. Connecting with recruiters in your target sector is productive and generates little friction.

How to Send Connection Requests

Always personalise your connection requests when possible. LinkedIn gives you 300 characters.

Examples:

• "Hi [Name], I came across your profile while researching [company]. I work in [field] and would love to connect with other professionals in this space."
• "Hi [Name], I noticed we are both alumni of [university] — always keen to connect with fellow graduates working in [sector]."
• "Hi [Name], I enjoyed your comment on [post topic] — would love to add you to my network."

Personalised requests have significantly higher acceptance rates than blank requests.

Quality Over Quantity

It is tempting to accept every connection request to build numbers. Resist. An irrelevant network is not useful. Be selective about who you connect with, and build a network of people who are genuinely relevant to your professional world.

At the same time, do not be too precious. LinkedIn is a professional network, not an exclusive club. A thoughtful connection request from someone in a related field is generally worth accepting.

After Connecting

Thank new connections with a brief message when their acceptance makes sense — especially for warmer connections. Do not immediately pitch yourself or ask for anything. Let the connection establish naturally.

Over time, engage with your connections' content. This maintains the relationship and keeps you visible in their network.

Use CVCircuit alongside your growing LinkedIn network — when your connections lead to opportunities, you need a CV that represents you as well as your profile does.
