What Is Dark Social and How Can Marketers Use It?

Hello!

Digital marketing is a constantly evolving field. New trends emerge, fresh channels appear, and marketers must continually adapt to stay ahead.

One key area for B2B, SaaS, and technology marketers is far from new—it has existed for years, even decades. Only recently has it been properly named and recognized for its true value in the digital age: “dark social.”

What exactly is dark social? Is it some mysterious group exchanging messages in secret? Not at all.

In this article, we explore:

• What “dark social” really means
• Real-world examples, especially in B2B marketing
• Dark social’s role in demand generation
• Challenges of tracking dark social—and how to overcome them
• The most effective content types for leveraging dark social

What Is Dark Social?

Just as astrophysicists describe “dark matter” as the invisible force holding the universe together, dark social represents the vast majority of online conversations that remain hidden from public view. It happens in private Slack threads, email exchanges, direct messages, and even offline—at trade shows or around the office water cooler.

Because these interactions occur privately, two realities emerge:

• Marketers find it difficult to track and attribute leads or conversions accurately
• Dark social remains one of the most powerful channels for building genuine interest and trust, especially in B2B

Which drives more impact: discovering a blog post on your own, or receiving a recommendation from a trusted colleague who believes it’s relevant to your business? (Blog posts certainly have their place—we’ll discuss that later.)

Dark social has existed since the earliest instant-messaging tools and continues to be one of the most common ways professionals share information.

Examples of Dark Social in B2B

Here are typical B2B scenarios:

• Andrew, an accountant, messages his manager Maureen on Slack about productivity software discussed in a professional group
• CIO Colin emails his technical team asking for recommendations on reliable help-desk outsourcing providers
• VP Victor mentions a podcast solution for budget challenges to President Patricia during a coffee break

Dark social spans multiple formats:

• Private group chats on Slack or Discord
• Direct messaging via WhatsApp or Facebook Messenger
• Links shared by others on forums like Reddit
• In-person conversations at events or in the office
• Individual emails and direct messages

In short, dark social is simply word-of-mouth marketing updated for the digital era—nothing new or suspicious.

Why Dark Social Matters for B2B Marketing

The core reason is trust. Professionals are bombarded daily with sales messages across every channel. While many offerings are genuinely valuable, it’s hard to separate signal from noise.

Now imagine logging into Slack and hearing from a trusted colleague who has already researched solutions relevant to your business. That personal recommendation carries far more weight than any advertisement.

Dark Social and Demand Generation: A Perfect Match

Traditional lead generation (demand capture) typically reaches only about 5% of your potential audience. The remaining 95% may not even know your brand or the problems you solve exist.

Demand generation changes that equation. By creating valuable content—podcasts, videos, and thought leadership—you reach early adopters who then share insights through dark social with colleagues and decision-makers they trust. This ripple effect can dramatically expand your reach.

How to Measure Dark Social

Dark social is inherently difficult to track, but not impossible. Here are proven methods:

Ask Directly

Include an optional “How did you hear about us?” field on conversion forms. You’ll often discover that recommendations from colleagues or industry peers played a key role.

Monitor Brand Searches

Sustained increases in branded search volume after targeted outreach frequently signal dark social activity.

Use GA4 Attribution

Google Analytics 4’s Attribution reports reveal the full journey of touchpoints leading to conversion, helping identify patterns linked to dark social influence.

Track Facebook-to-Google Conversions

Meta’s tracking pixel can measure how many users who viewed your content later searched for your brand on Google, providing valuable indirect insight.

Best Content Types for Dark Social

To maximize dark social impact, create content that is both informative and easily shareable:

• Informative: Clearly explain how your solution solves real business problems and why your company delivers the best results
• Shareable: Keep messages concise, engaging, and suitable for quick sharing across messaging apps and social platforms

Short-form videos (TikTok, Instagram Reels, YouTube Shorts) and podcasts excel at meeting both criteria.
