B2B Influencer Strategy Shifts as AI Search Reshapes Vendor Discovery
B2B marketers are rebuilding creator and influencer programs around a buyer who now starts with an AI answer. EMARKETER published research on August 18, 2026 on how trusted third-party voices shape B2B buyer research and AI-driven discovery. It reports that 77% of B2B marketers worldwide plan to increase paid social investment over the next 12 months.
What EMARKETER’s B2B Social and Influencer Report Covers
The report is titled B2B Social Media and Influencer Marketing 2026 and is authored by Kelsey Voss. EMARKETER frames it around a single question: how can B2B marketers adapt social and influencer strategies as buyers and AI systems place more weight on outside sources.
The premise EMARKETER sets out is that B2B brands build credibility beyond their own messaging. Buyers lean on experts, customers and peers to evaluate vendors. AI systems then cite many of the same third-party sources when they answer a buyer’s question. The report examines whether paid social investment and influencer programs are keeping pace with that behaviour.
The headline figure EMARKETER publishes is the planned spending increase: 77% of B2B marketers worldwide expect to raise paid social investment in the next 12 months, which EMARKETER identifies as the fastest-rising planned investment area it tracked.
Marketing Week reached a similar conclusion in analysis published the next morning. B2B decision-making, it argued, is being fundamentally recast, with AI-driven search, digital communities and the weight of peer advocacy forcing brands to adapt quickly to how purchase decisions now get made.
Where the B2B Influencer and AI Search Reporting Comes From
The research is published by EMARKETER as B2B Social Media and Influencer Marketing 2026, dated August 18, 2026. Marketing Week’s Emily Manock published the companion analysis on August 19, 2026. Both are partly subscriber-only. The figures and framing above are drawn from the publicly available portions of each, and nothing here is taken from the gated sections.
How Creator Strategy Fits B2B Buying in 2026
The platforms have been building toward this for months. LinkedIn moved to formalise brand and creator partnerships when it launched its Creator Marketplace and BrandWorks for B2B marketers. The demand side explains why. LinkedIn’s own research found that 74% of B2B marketers say buyers distrust traditional marketing, which pushes budget toward voices that do not sound like a brand.
Buyer behaviour is moving in parallel. TrustRadius found that 63% of B2B buyers use AI to research purchases while 94% of them fact-check what it tells them. That second number is the important one for creator strategy. A buyer who checks an AI answer goes looking for a human source, and the sources they find are reviews, communities and creators.
Marketing Week reported in April that Forrester had found two-thirds of B2B buyers choose a vendor before engaging, describing buying as “an act of confirmation, not selection.” Third-party voices are doing much of that confirming.
Talking Shift: A Creator Program Is Now an AI Visibility Program
Start Some Shift sees these as one budget line wearing two labels. AI answer engines describe a vendor by pulling from sources they treat as independent. Your website is a source about you. A creator’s post about you is something an AI reads as outside validation, and it is far more likely to end up quoted in an answer a buyer never traces back.
That changes what a creator program is for. Most B2B teams still measure creator work on impressions and engagement, which are human metrics. Start Some Shift’s take: “Creator content is the only marketing asset you fund that an AI will repeat back to your buyer as if it were neutral.” Fund it accordingly. Ask whether the creator content you paid for last quarter shows up when you ask ChatGPT about your category. If it does not, you bought reach and missed the part that compounds.
What B2B Marketers Should Do About Creator Strategy in AI Search
- Query your category in ChatGPT and Google AI answers, then check whether any creator content you funded appears in the response.
- Brief creators to publish on indexable, public platforms rather than gated formats an AI system cannot read.
- Add citation appearances to your creator reporting alongside impressions and engagement.
- Fund fewer creators for longer, since repeat coverage from a consistent voice builds a stronger source record than one-off posts.
- Give a buyer a reason to pick you inside a short AI-generated shortlist, because the answer names your competitors in the same breath.
- Route paid social budget toward the creators buyers already read, since 77% of B2B marketers plan to raise that spend and competition for the same voices will rise with it.
- Encourage your own executives to publish consistently, so your brand has named humans in the record and not only a website.
What to Watch Next in B2B Influencer Marketing
Watch whether measurement vendors start reporting creator content citations inside AI answers, which would turn a theory into a metric. Watch too whether that 77% planned increase in paid social spend survives contact with budget season, since planned intent and booked spend often diverge in B2B.
