Social Selling: What It Is and How It Differs from Spamming on LinkedIn

In this article you will find the definition of social selling, the four pillars it stands on and what is left of the Social Selling Index after the 2026 changes. I also show how social selling differs from social media marketing and from cold calling, in what order to roll it out in a B2B sales team and what not to do at the start.

I will start with what social selling is not, because that is where most of the confusion comes from. It is not selling on social media, and it is not sending an offer to everyone who accepted your connection request. It is also not a bot that writes for you, “I see we are in the same industry, can I present our offer?”. That is cold calling moved to another channel, with the difference that here the other person can see your name and your company. The effect shows in the numbers: the conversion of mass connection requests and templated messages fell from 60% to 30% in two years.

What social selling is: the definition

Social selling is a sales strategy that uses social media to build relationships, trust and credibility with potential customers before a sales conversation happens. It relies on the salesperson’s personal brand, on sharing knowledge and valuable content, and not on sending offers. The point is not to sell on LinkedIn, but to win business customers from a warmer starting point: by the time you start the conversation, the other side already knows who you are and why they should listen to you.

Where does so much confusion come from? From the name. “Social selling” sounds like “selling on social media”, so companies roll it out as one more outreach channel and are surprised that it does not work.

Social selling on LinkedIn

Facebook and Instagram are social platforms too, so why LinkedIn for B2B? Because in Poland that is where decision makers look for solutions and where their companies and job titles are listed. The basic tool is an ordinary profile, and for teams that want to look for customers systematically, it is Sales Navigator.

The four pillars of social selling

1. A profile that survives scrutiny

The first thing an interested person does is visit your profile. A salesperson’s profile has to be consistent with what they sell, and that is not a matter of looks. The algorithm judges that consistency the same way a human does.

I found that out on my own account. I listed on my profile all the universities where I lecture, and the algorithm stopped treating me as a consultant and digital marketer. It put me among academic lecturers, and my reach among clients dropped. It only helped when I removed those entries. I described it in the post on how the LinkedIn algorithm really works.

2. The right network of contacts

A network built from random people is a counter, not a network. What matters is how well your contacts match the people you sell to, because only that kind of network has sales potential. The most common mistakes I see are no segmentation and one and the same connection request sent to everyone.

That is why I am for a note in the connection request. My software has sent a few million connection requests, so I know what works: the note says who you are, how you know about this person, why you are connecting and what happens next. I talked about it more in the Escola Mobile podcast.

3. Content that gives people a reason to talk

This is the pillar everyone wants to start with, and most people get it wrong. Content in social selling is not the company’s marketing materials, but valuable content from the salesperson’s experience. And it does not have to mean your own posts. Comments on LinkedIn get disproportionately large reach compared to posts, and a good comment can collect over ten thousand impressions. That is the best start for a salesperson who says “I have nothing to write about”.

My rule is three to five in-depth comments a day. In-depth meaning they add something to the conversation, not “great post!”.

4. Relationships that are kept up, not renewed when there is an offer

A contact you only reach out to when you have something to sell is not a relationship. With every contact who matters to me, I get in touch at least once every six months for no sales reason, with a plain “how are you?”. A bot reminds me who I have not talked to for six months, but I write the message myself. You can automate the reminder about a contact, never the content of the relationship.

On top of that comes speed. In social selling campaigns plenty of deals are lost only because the salesperson replies after a week.

Social selling, social media marketing and cold calling

	Social selling	Social media marketing	Cold calling
Who runs it	the salesperson	the brand, the marketing team	the salesperson
From which account	personal profile	company page	phone, email
What to measure it by	sales conversations started	reach and engagement	number of calls and meetings
Where the conversation starts	the recipient already knows you	the recipient knows the brand	the recipient does not know who you are

The last row matters most. In a B2B buying process the first thing an interested person does is open your profile, so in social selling the conversation starts from a warmer point. It just takes time. Companies that roll out social selling expecting leads within a week usually give up just when the process starts to work.

Social Selling Index: what is left of it

LinkedIn has a Social Selling Index (SSI) on a scale of 0 to 100, made of four pillars worth 25 points each: establishing your professional brand, finding the right people, engaging with insights and building relationships. Since 8 September 2026 the full report at linkedin.com/sales/ssi is only visible on an account with a Sales Navigator license, and everyone else gets the message “You do not have access to SSI”. I described it in the post on SSI behind the Sales Navigator paywall.

How do I treat it? For years as a vanity metric. SSI counts activity, not results: none of the four pillars includes conversations or signed deals. My score is 65 out of 100 with an industry average of 34. I once pushed it up to 88 and nothing changed in my sales. LinkedIn itself admits: “A high SSI score doesn’t always represent the efficacy of a sales person or correlate with measurable sales outcomes”.

It has one useful thing: the card with the industry the algorithm has assigned you to. For me it is “Sales professionals in the Business Consulting and Services industry”. If you do not have a Navigator license, you can check the same thing by the posts LinkedIn puts in your feed and by who views your profile. Everything about the score itself is in the guide to the Social Selling Index.

How to roll out social selling in a B2B team

Rolling out social selling is a change of habits, not a tool purchase. The order matters, and most companies do it backwards: they start with an order to publish and end up with a discouraged team.

1. Profiles first. Before anyone publishes anything, the salespeople’s profiles must be consistent with what they sell. An empty account is not enough to start.
2. Then reading. Each salesperson follows people from their segment and industry discussions and reads what is going on in their world. That is the map of the industry.
3. Then comments. Three to five in-depth ones a day. This stage builds visibility without inventing your own topics.
4. Only then your own posts, coming from experience, not from a publishing calendar.
5. Tools last, meaning Sales Navigator and bots that remind you about contacts. A tool scales a habit, but it does not replace it.

How long does it take? Less than you think, but every day. To managers who have 20 minutes a day for LinkedIn I say: pick four people and spend five minutes talking to each.

What not to do at the start

• Do not send everyone the same connection request or the same message with an offer in a PDF. Templates are exactly those 30% conversion instead of 60%.
• Do not connect salespeople’s accounts to bots that write for them. I have seen Sales Navigator accounts blocked after installing such a tool, and LinkedIn kept charging for the license anyway.
• Do not set up groups where members like each other’s posts. Since 2026 LinkedIn shows the content of such groups only inside the group, so the reach outside drops.
• Do not measure success by impressions or SSI.

How to measure the results of social selling

Measure conversations, not impressions. I look at the number of sales conversations started, InMail replies, connection request conversion and sales opportunities in the CRM. Of the signals inside LinkedIn itself, the ones that tell me the most are saves and sends of posts, not likes, as I wrote in the text on how to use LinkedIn in 2026.

The most honest measurement is a control group: some of the salespeople work the new way, some the old way, and after a quarter or two you compare sales opportunities in the CRM and deal closing time. With my clients the average is 47% more qualified leads in the first three months after the training.

If you want to roll out social selling in your team and skip the most common mistakes, I run a B2B social selling training on LinkedIn. We do 80% of the exercises on your accounts.
