LinkedIn dominates B2B social media with 86% marketer adoption and 113% return on ad spend—the only major platform achieving positive returns for B2B companies. For marketing managers planning 2025 strategies, success requires prioritising video content, employee advocacy programmes, and AI-powered workflows integrated with platforms like HubSpot. At Whitehat, we help B2B companies transform their social media from random acts of marketing into predictable pipeline generators.
The B2B social media landscape has fundamentally shifted. Buyers now complete 57-70% of their research before ever contacting sales, engaging with an average of 13 pieces of content before purchase. With 75% of B2B buyers using social media to inform purchasing decisions—rising to 84% among C-level executives—your social presence directly impacts pipeline.
This comprehensive guide synthesises the latest 2024-2025 research to give you actionable strategies backed by data. Whether you're optimising LinkedIn campaigns, implementing employee advocacy, or integrating social media with your HubSpot CRM, you'll find benchmarks and tactics that work.
Which Social Media Platforms Generate the Most B2B Leads?
LinkedIn generates 97% of all B2B social media leads, making it the undisputed leader for professional marketing. The platform hierarchy for B2B marketing has crystallised in 2024-2025, with clear leaders and emerging challengers that Whitehat tracks across our client base.
LinkedIn's dominance is comprehensive: 86% of B2B marketers use it, 44% rank it as their most important platform, and 97% use it for content marketing distribution. The platform delivers 2x higher conversion rates than competitors. With 45 million UK users representing 64.9% of the population and ad reach growing 15.4% between 2024 and 2025, LinkedIn's position in the UK market is particularly strong.
| Platform | B2B Marketer Usage | Key Strength |
|---|---|---|
| 86% | 97% of B2B leads, 113% ROAS | |
| 79% | Broad reach, lower CPL | |
| YouTube | 56% | 50.9% of buyers prefer for research |
| 60% | 20x more engagement than LinkedIn | |
| TikTok | 19% | Emerging for younger B2B buyers |
Platform trends reveal significant movement: 68% of marketers increased LinkedIn usage in the past year, while 32% have decreased X/Twitter usage due to brand safety concerns—only 4% of marketers now consider X brand-safe. For B2B marketing managers, this data supports concentrating resources on LinkedIn while experimenting with emerging platforms like Threads (320 million users) for early-adopter advantages.

How Does the LinkedIn Algorithm Work in 2025?
LinkedIn's 2025 algorithm intentionally prevents content from going viral to surface professionally relevant content instead. This fundamental shift means views have dropped 50%, engagement 25%, and follower growth 59%—but this represents a quality filter, not a failure. Understanding these changes helps Whitehat clients create content that actually reaches decision-makers.
The algorithm now prioritises substance over sensation. Content with specific data points receives 3.7x more reach than generalised content. Interactions from industry experts carry 7-9x more algorithmic value than random connections. The algorithm shows older posts (2-3 weeks) if more relevant to users' professional interests, extending content lifespan for quality creators.
LinkedIn Best Practices for 2025:
- Post 3-5 times per week—companies posting weekly see a 5x lift in followers
- Best times: Tuesday through Thursday, 9AM-2PM local time
- Use native formats: Videos, carousels, and text posts outperform external links
- LinkedIn newsletters provide a 4x boost compared to standalone articles
- First-degree connections see content 5x more often than second-degree
Employee advocacy has become critical under the new algorithm. B2B brands using employee advocacy see 40% higher engagement rates, making it essential for any serious inbound marketing strategy. The algorithm rewards authentic professional voices over polished corporate messaging.

What ROI Should B2B Companies Expect from Social Media?
A solid B2B social media ROI is 3:1 for organic efforts and 5:1 for paid campaigns—earning £3-£5 for every £1 spent. These benchmarks vary significantly by platform, with LinkedIn delivering the only positive returns among major platforms for B2B SaaS companies. Whitehat helps clients establish realistic targets based on these industry benchmarks.
LinkedIn advertising delivers 113% ROAS—outperforming Google (98%) and Meta (104%) for B2B. Marketers see up to 2x higher conversion rates on LinkedIn, leading B2B marketers to increase LinkedIn advertising allocation from 31% to 39% of total ad spend in 2024. This shift reflects the platform's superior targeting for professional audiences.

Why Is Video Essential for B2B Social Media Success?
Video content generates 1200% higher engagement than text and images combined, making it non-negotiable for B2B social media success. In 2025, 89% of businesses use video as a marketing tool—the highest ever recorded—with 93% reporting good ROI from video marketing. Whitehat recommends video as the anchor of any B2B content strategy.
For B2B specifically, 87% actively incorporate video in strategies, 58% rank video as their most effective content strategy, and 70% of B2B buyers engage with video during purchasing decisions. Video marketers experience 49% faster revenue growth compared to non-video marketers.
Video length matters for engagement. Research shows 73% of marketers believe videos between 30 seconds and 2 minutes are most effective, while videos under 90 seconds maintain 50% retention rates. Interestingly, videos over 60 minutes show 58% average play rate and 13% conversion rate—higher than shorter videos for in-depth educational content.
LinkedIn is now the #1 most widely used video marketing platform at 70% of video marketers—a first in 2025. Live video also delivers exceptional results: 91% of B2B professionals rank webinars as their favourite content format, and 73% of B2B webinar attendees become leads versus 20-40% for B2C. Integrating video with your HubSpot CRM enables tracking from first view to closed deal.

How Can Employee Advocacy Transform B2B Social Results?
Content shared by employees receives 8x more engagement than brand-shared content, making employee advocacy the highest-leverage opportunity in B2B social media. Yet 74% of marketers cite getting employees to participate as their greatest obstacle. Understanding both the opportunity and implementation challenges helps Whitehat clients build programmes that actually work.
The ROI from employee advocacy is substantial. Companies with advocacy programmes see 20% faster revenue growth, and sales leads through employee advocacy convert 7x more often than other channels. Employee advocacy either doubles (73% of cases) or triples (26%) social media engagement, delivering cost-per-click under £1 for 23% of organisations.
Building an Effective Employee Advocacy Programme:
The solution to participation challenges lies in making sharing effortless. 75% of successful programmes provide ready-made images and graphics, while 68% provide video content. Critically, 72% of engaged users say they would post about their company if content was written for them.
Start small: identify 5-10 enthusiastic employees, provide them with weekly shareable content, track results for 90 days, then expand based on what works. HubSpot's social tools can streamline content distribution to employee advocates.
The business case is clear: 76% of businesses have now implemented employee advocacy programmes, recognising that authentic employee voices outperform corporate messaging. For UK B2B companies using inbound marketing strategies, employee advocacy represents the fastest path to increased reach without increased ad spend.
How Is AI Changing B2B Social Media Marketing?
95% of B2B marketers now use AI-powered applications, with 89% using AI specifically for content creation—making AI adoption essentially table stakes for competitive B2B marketing. At Whitehat's AI consultancy, we help companies implement AI that enhances rather than replaces human creativity.
ChatGPT dominates with 81.85% global market share for AI chatbots, while 91% of generative AI users rely on free tools. AI usage for social media content writing increased from 45% in 2024 to 67% in 2025. The productivity gains are clear: 87% report improved productivity from AI content creation, and 83% say generative AI helps them create significantly more content.
However, consumer concerns about AI authenticity are growing. The top concern is companies posting AI-generated content without disclosure, while consumers' number one request for brands in 2026 is human-generated content. This creates a paradox: AI is essential for productivity, but authenticity remains a premium. Only 39% see improved content performance from AI, and 12% report quality actually decreased.
For social media automation specifically, 76% of companies use marketing automation, delivering £5.44 return on every £1 spent over three years and generating a 10% increase in sales pipeline for B2B users. Social media post scheduling ranks as the #1 marketing automation use case at 88%. Integrating AI tools with HubSpot creates a unified workflow from content creation through to lead attribution.

How Much Should B2B Companies Spend on Social Media?
UK B2B companies allocate 10.78% of budgets to marketing for product companies and 9.44% for services—above the US average of 8.7%. Marketing leaders allocate 12.1% of their budgets specifically to social media marketing, projecting this will reach over 19% within five years. UK digital marketing spending for B2B increased 14.6% year-over-year.
The typical organic versus paid split for B2B success is 70/30—70% to organic efforts (brand building, thought leadership) and 30% to paid social (targeted conversion campaigns). However, organic reach continues declining: Facebook organic reach has dropped to 2-5%, Instagram to approximately 4% (down 18% year-over-year), while LinkedIn maintains around 6.4%.
| Platform/Industry | Cost Per Lead | Notes |
|---|---|---|
| LinkedIn (UK/Europe) | £100-£150 | Higher quality, 2-3x better conversion |
| Facebook B2B | £5-£50 | Lower quality, volume play |
| B2B SaaS average | £188 | Industry benchmark |
| Financial Services | £461 | High-value, competitive |
| IT & Managed Services | £501 | Complex sales cycles |
Most B2B organisations operate with 1-3 person social media teams, with 58% having small or one-person content marketing teams. The resource constraints make efficiency critical—which is why Whitehat recommends focusing on LinkedIn and video content where ROI is highest, rather than spreading efforts thin across all platforms.
