LinkedIn, AI and the end of ‘spray and pray’: where social media is heading in 2026

Social media for professional services has always been a strange beast — too serious for TikTok, too buttoned-up for memes, and too time-poor for constant posting. But 2025 is quietly redrawing the rules…So what awaits for us in 2026? Platforms like LinkedIn are shifting, algorithms are maturing, and artificial intelligence is weaving itself into every stage of content creation and client listening.

The good news? For marketers who prefer substance over spectacle, this is the best environment we’ve seen in years.

LinkedIn doubles down on video and creators

LinkedIn is finally taking B2B content seriously — and professionally. The platform has expanded its BrandLink programme (formerly “Wire”) to include publishers and individual creators, encouraging firms to use short-form video and storytelling to reach decision-makers. Video views are up by more than 30% year-on-year, and ad spend from professional services is following suit.

Why it matters: LinkedIn is betting on human-to-human engagement rather than faceless corporate updates. For example, Deloitte UK recently launched a “60 Seconds of Strategy” series featuring partners discussing client challenges in punchy, 45-second clips. Each video ends with a direct takeaway — no fluff, no jargon — and routinely gains more traction than traditional whitepaper posts ever did.

For smaller firms, this signals opportunity rather than intimidation. You don’t need cinematic production; you need clarity and presence. A short, well-lit clip of a partner explaining how their firm helped a client navigate ESG reporting will now outperform a PDF link every time.

Action point: Audit your firm’s LinkedIn presence. If video isn’t yet part of your marketing plan, start small — think monthly thought-leadership clips or client-story snippets — but start now.

The algorithm is rewarding originality, not repetition

LinkedIn’s 2025 algorithm refresh has quietly changed the game. Posts that generate meaningful interactions — thoughtful comments, saves, and discussions — are being prioritised over likes and shares. Meanwhile, recycled or generic content is being demoted.

In practice, this means professional services marketers need to stop treating LinkedIn like a noticeboard. A partner reposting the same event photo with “Great day at the conference!” will now sink without trace. But when that same partner shares one sharp insight from a client conversation or project — for instance, “Most mid-market CEOs still underestimate how AI impacts client data compliance” — the platform rewards it.

A mid-sized accountancy firm in Manchester recently tested this approach. Their marketing team replaced two generic weekly posts with one in-depth reflection by a tax partner explaining upcoming HMRC digitalisation changes. Engagement jumped 270% in a month — and two inbound client enquiries followed.

Action point: Encourage subject-matter experts to post stories, not announcements. Train them to translate their technical expertise into insights that spark dialogue.

The great channel rethink: fewer, smarter, AI-powered

According to Axios, nearly 40% of communications professionals have abandoned X (formerly Twitter) for professional use this year. Meanwhile, AI adoption among marketers has surged from 28% to 75% in just two years. The message is clear: the market is consolidating around fewer, more focused channels — and smarter use of data.

Professional services marketers are recognising that maintaining five platforms poorly is far less effective than owning one or two strategically. LinkedIn remains the clear leader for B2B engagement, followed by YouTube for long-form storytelling and niche podcasts for thought leadership.

AI is reshaping how content is planned and measured, not just written. Forward-thinking firms are using AI to identify trending discussion themes among their target audience, or to audit which past posts drove the most qualified leads. Some are even using AI to listen — analysing client feedback, comments, and sentiment to detect early signs of shifting priorities.

Action point: Review where your firm’s audience actually spends time. Cut channels that deliver little but vanity metrics. Use AI tools for listening, insights, and scheduling — but keep the human voice firmly in the foreground.

The bottom line

Social media in 2025 is less about presence and more about precision. The firms winning visibility aren’t shouting louder — they’re listening better, speaking authentically, and showing their people. LinkedIn is maturing into the professional stage it always promised to be. And for marketers who value intelligent storytelling, that’s an opportunity worth seizing before your competitors do.
