TL:DR
We ran a quick internal test to understand LinkedIn’s Social Selling Index (SSI) and what actually drives influence on the platform. Our goal? To find out whether it’s worth the effort for B2B marketers, especially in niche sectors to invest time into personal posting. The headline takeaway: yes, personal posts often outperform company ones, but success depends on the size of your network and the quality of engagement you can generate. It’s not about posting more, it’s about posting smarter. And for those who crack it, the impact can be meaningful.
We ran a little experiment. Nothing rigorous, nothing lab-coated, just a simple test using our own team’s LinkedIn SSI scores. We looked at how active each person was, what kind of posts they shared, and how their profiles stacked up.
The reason? We’ve noticed something: personal posts from individuals often outperform branded company content. But not every team member sees the same success. So we asked ourselves: how much effort does it actually take to be effective on LinkedIn? Is it worth the time? Is becoming more influential on LinkedIn a smart investment or just more work?
What is LinkedIn SSI?
Lets start at the beginning. LinkedIn’s Social Selling Index (SSI) is a score between 0 and 100 that reflects how well you use LinkedIn to establish your professional brand, connect with the right people, engage with insights, and build relationships. In simple terms: the higher your score, the more the algorithm will amplify your content. It turns thought leadership into a game of influence. You can see yours here.

Why this matters
SSI is tightly linked to your visibility on LinkedIn. A stronger score means better distribution of your content more reach, without more effort. It also elevates your authority and discoverability, helping you get found by peers and prospects. More impact, same effort.
Essentially, SSI is a numerical score for how much the LinkedIn algorithm favours what you post.
Quality vs Quantity: The LinkedIn reality
The test made one thing clear: quality beats consistency every time. The classic advice is to post 2–4 times a week. But if your posts get tumbleweed-level engagement, it won’t move the needle.
What does work is one solid post that prompts conversation. And that’s where your network size comes in.
The larger your initial network, the more likely you’ll get early engagement triggering the network effect and helping your post travel further. Small networks struggle to break through this barrier, making that first 500+ milestone more meaningful than it seems.
The SSI scoring ladder
From what we tracked, four rough thresholds emerged:
- 0–30: You’ve got a profile, but little activity
- 30–40: You’re liking and occasionally commenting, but not posting
- 50–70: You’re posting regularly, earning engagement, and have a network of 500+
- 70+: You’ve entered the influence elite of your sector
Here’s the kicker: you don’t get to 50+ without two things: a decent-sized network and posts people actually respond to.
Complete profiles and original content matter. So do thoughtful comments and likes. Reshares? Less so. Shares of your posts? Much more.
How people move between tiers
To go from 0–30 to 30–40, you need to:
- Be more active in liking others’ content
- Start commenting, even occasionally
- You don’t need to post yet, but adding connections will help
To get from 30–40 to 50+, you’ll need:
- 500+ connections
- Original posts that generate engagement especially comments
- Ongoing activity that shows you’re building your network
Once you’re in the 50–70 bracket, you’re considered a credible voice in your industry. But the score decays quickly. You’re only as visible as your last post – LinkedIn’s way of encouraging (or coercing) constant activity.
The niche market challenge
If you’re in a specialist B2B sector like most of Velo’s clients, there’s an added hurdle. Your market might not move fast enough to generate hot takes every week, yet LinkedIn’s algorithm rewards originality and debate. That’s easier in fast-changing spaces like cybersecurity or AI. But in areas like engineering, the built environment or compliance, where the fundamentals shift slowly, it’s harder to keep content feeling fresh.
Repeating yourself won’t work. Your network will only engage if you bring new thinking, which requires deep insight or a fast-evolving landscape. Ideally, both.
What doesn’t influence SSI
This might sting: your authority on other platforms doesn’t help.
We saw no crossover benefit from large followings or high engagement on Twitter/X, TikTok or Instagram. LinkedIn only cares about LinkedIn. Sad, considering we have 3 Instagram influencers in our team.
What does move the needle?
Based on what we saw, here’s what makes the biggest difference:
- Post original content regularly. 2–4 times a week is fine, but quality trumps quantity. Focus on posts that prompt comments – they count more than likes.
- Be part of the conversation. Comment meaningfully on others’ posts in your space. It builds goodwill and visibility.
- Optimise your profile. Follow Tom’s guide here – a complete, detailed profile gets rewarded.
- Connect with purpose. Get past the 500+ mark. Connect with colleagues, clients, and collaborators. It’s a network, not a vault.
Do these well, and you’ll start to see better traction. Same effort, more return.
