Social Selling Index (SSI) is a metric developed by LinkedIn that measures how effectively you build business relationships and generate leads on the platform.
A score from 0 to 100 reflects your activity across four key areas.
In 2026, SSI is one of the most important parameters for sales professionals, freelancers and B2B specialists - companies with a high SSI score generate 78% more leads than those with a low one.
If you want to know what SSI is, how to check it and how to improve it systematically, this guide is for you.
What Is the Social Selling Index (SSI)?
The Social Selling Index is a metric introduced by LinkedIn that measures how effectively you carry out sales and networking activity on the platform.
The score is updated weekly and ranges from 0 to 100 points - the higher, the better.
LinkedIn introduced SSI in 2014, when the platform began promoting the concept of social selling - that is, selling through relationship-building and sharing valuable content, rather than classic cold calling.
SSI quickly became a standard tool for B2B sales teams, HR professionals and personal branding specialists.
According to LinkedIn data:
- people with a high SSI have 45% greater odds of hitting their sales targets in a given quarter
- they generate 78% more new leads than those with a low score
- they are 51% more likely to exceed their sales quota
- they achieve 80% higher productivity in prospecting
Important note: SSI measures activity and engagement, not sales results directly. It is a correlation, not causation - but a very strong one worth taking seriously.
How to Check Your Social Selling Index on LinkedIn
Checking your SSI is completely free and takes less than a minute. You do not need a LinkedIn Premium account or Sales Navigator subscription.
Step by step:
- Log in to your LinkedIn account
- Go to: linkedin.com/sales/ssi
- Click "Get your free score" (if you see a sales page)
- You will see your overall score and points for each of the 4 pillars
- Below the chart you will find a comparison with the average in your industry and your network
The dashboard also shows a trend - whether your score is rising, falling or staying stable. This is key information, because SSI is dynamic - it changes every week depending on your activity.
Tip: The SSI tab is only accessible via a desktop browser. The LinkedIn mobile app does not display the full SSI dashboard.
The 4 Pillars of the Social Selling Index - a Detailed Overview
Each of the four SSI pillars is scored on a scale of 0 to 25 points.
Together they add up to a maximum of 100 points. Below I cover each pillar in detail and provide concrete ways to improve your scores.
1. Establish Your Professional Brand
This pillar evaluates how complete and professional your profile is, and whether you publish content that builds your authority in your field.
What counts towards this pillar:
- profile completeness at "All-Star" level
- professional profile photo and banner
- a well-written summary (the "About" section)
- publishing articles and posts regularly
- skill endorsements from your connections
- recommendations from colleagues and clients
This is one of the pillars where first impressions matter enormously. A profile without a photo, or with an outdated low-quality image, will immediately lower your score - and the trust of potential clients.
2. Find the Right People
This pillar measures whether you actively search for potential clients and expand your network with people from your target audience.
What counts towards this pillar:
- using the LinkedIn search with filters (industry, job title, location)
- viewing profiles of people from your target audience
- sending connection requests with a personalised message
- regularly accepting and sending connection requests
- using the "People You May Know" section
3. Engage with Insights
This pillar assesses whether you actively participate in discussions and whether your content is valuable to the LinkedIn community.
What counts towards this pillar:
- publishing posts and articles (consistency beats a one-off viral moment)
- commenting on other users' posts (especially within your industry)
- sharing valuable content with your own commentary
- reacting to posts (likes, reactions)
- participating in industry groups
4. Build Relationships
This pillar measures the quality and activity of your relationships - whether you communicate with your connections regularly and whether you build your network among decision-makers.
What counts towards this pillar:
- sending and receiving InMail messages and DMs
- responding to messages promptly
- engaging with people in decision-making roles (managers, directors, business owners)
- staying in touch with current and former colleagues
- being active with 2nd-degree connections
What Is a Good SSI Score? Benchmarks for 2026
The average SSI score for active LinkedIn users is around 30-40 points. The table below shows how to interpret your score:
| SSI Score | Rating | What It Means |
|---|---|---|
| 0 - 25 | Weak | Incomplete profile, no activity, LinkedIn barely used |
| 26 - 50 | Average | Basic activity, but LinkedIn is not being used to its full potential |
| 51 - 75 | Good | Deliberate use of the platform, effective network-building |
| 76 - 100 | Very good / top | Social selling expert, LinkedIn is the primary business channel |
LinkedIn also provides average scores by industry. The highest SSI scores are typically found in technology, finance, consulting and marketing.
If your score is above the average for your industry - that is already a positive sign.
It is worth monitoring your score weekly and comparing it with the average in your network - this information is available directly on the SSI dashboard.
How to Improve Your Social Selling Index - 7 Proven Tips
Improving your SSI requires consistency, not one-off actions. Below are 7 tips that produce the fastest score gains:
- Update your profile to All-Star level - fill in every section: headline, summary, experience, education, skills. LinkedIn rewards complete profiles with greater reach and a better SSI score in the "professional brand" pillar.
- Switch to a professional profile photo - this is one of the first things potential clients and recruiters notice. Research shows that profiles with a professional photo receive 14x more profile views than those without one. Avoid party selfies or holiday snaps - invest in a professional business photography session that immediately builds your credibility.
- Post consistently - at least 3 times a week - you do not need to write lengthy articles. Posts of 150-300 words sharing concrete industry observations are equally effective. The key is regularity - LinkedIn's algorithm rewards those who publish consistently.
- Comment on other people's posts - at least 5 comments a day - this is the fastest way to grow your "Engage with Insights" pillar score. Comments must be substantive (at least 2-3 sentences); "Great post!" is not enough.
- Expand your network with people from your target audience - send 5-10 connection requests a day with a personalised message. Mention where you came across the person or why you would like to connect. The acceptance rate for personalised requests is 3-4x higher than for default ones.
- Reply to messages promptly - the "Build Relationships" pillar is sensitive to response time. If someone writes to you, reply within 24 hours. Set up LinkedIn notifications so you never miss a message.
- Use LinkedIn search with filters - spend 10-15 minutes each day searching for decision-makers in your industry. Simply browsing their profiles already boosts your "Find the Right People" pillar score - even without sending a connection request.
Social Selling Index and Sales Results - Does SSI Actually Matter?
This is a question that often comes up among sceptics. The answer is: yes, but with a caveat.
According to LinkedIn data from 2025, salespeople with an SSI above 70 close 45% more deals than those with a low score.
More importantly, the time from first contact to signing a contract shrinks by an average of 20%.
It is worth bearing one thing in mind though: a high SSI is the result of activity, not its cause. In other words - if you are active on LinkedIn, your SSI grows.
And if you are active on LinkedIn, your sales results grow too. The correlation stems from the same underlying behaviour.
But that does not change the practical conclusion: consistent activity on LinkedIn - brand-building, engagement, relationships - translates into real business outcomes.
SSI is a metric that helps you monitor whether you are heading in the right direction.
An additional argument: 76% of B2B buyers are willing to have a conversation with a salesperson via social media, and 62% respond to messages from salespeople when those messages are properly tailored to their needs. LinkedIn is simply where your clients are.
The Role of Photography in Social Selling - Why Visual Personal Branding Matters
When a potential client lands on your LinkedIn profile, the very first thing they see is your profile photo and banner.
Not your experience, not your recommendations, not your posts - your photo. And in a fraction of a second, it determines whether they stay or click back.
This is not a subjective opinion - it is the finding of UX research and first-impression psychology. Profiles with a professionally shot photo receive:
- 14x more profile views
- 36x more messages
- significantly higher connection acceptance rates
In the context of SSI: a profile with a professional photo scores higher in the "Establish Your Professional Brand" pillar and builds the credibility that carries over into the other pillars - people are more likely to accept your connection requests, respond to your comments and reply to your messages.
If you sell physical products, add professional product photography to the mix as well.
More and more companies on LinkedIn publish posts featuring packshots, unboxing shots and lifestyle images. The quality of these visuals directly affects engagement and conversion rates.
At marszalstudio we help you build a visual personal brand on LinkedIn - from business and portrait photography sessions, through personal branding, to professional product photography for e-commerce brands.

FAQ - Frequently Asked Questions About the Social Selling Index
Is the Social Selling Index free?
Yes - checking your SSI is completely free. Simply go to linkedin.com/sales/ssi while logged in to your LinkedIn account.
You do not need a Premium subscription or Sales Navigator to view your score and the detailed dashboard broken down by all 4 pillars.
How often is the Social Selling Index updated?
The Social Selling Index is updated once a week. It is not a real-time metric, so you will not see changes immediately after publishing a post or adding a connection.
The score reflects your activity over the past 7 days and is recalculated once a week.
What is a good SSI score for a B2B salesperson?
For an active B2B salesperson, the target should be a score above 60 points.
According to LinkedIn data, salespeople with an SSI above 70 have 45% more sales opportunities and are 51% more likely to exceed their quota.
A score of 75+ places you among the top LinkedIn users in your industry. The average for active users is 30-40 points.
Does SSI affect the reach of your posts on LinkedIn?
Directly - no. LinkedIn does not officially confirm that SSI is a ranking factor in the feed algorithm.
Indirectly - yes.
A high SSI results from activity (publishing, commenting, building your network), and that same activity leads to greater reach.
The larger and more engaged your network, the more people will see your posts - regardless of SSI itself.
