You can't hire content writers who are knowledgeable about every topic, which is where subject matter experts (SMEs) come in. SMEs can provide valuable insight, help craft content, and offer feedback.
Using subject matter experts in content marketing means borrowing the first-hand knowledge of people who do the work — product managers, engineers, practitioners — to make your content accurate, original, and credible enough to earn trust from readers, Google, and AI search engines. No content team can be expert in everything, so the best B2B marketers build a repeatable process: find the right expert, prepare well, interview efficiently, make it worth their time, and turn the conversation into content only an insider could produce. Here's how, in five steps.
A subject matter expert (SME) is someone with deep, specialized knowledge of a particular field, built through years of hands-on experience, study, or both. In content marketing, an SME is the person whose first-hand insight makes a piece authoritative — the engineer who can explain why a technical approach actually works, or the practitioner who knows what really happens day to day.

High-quality content drives traffic, builds brand awareness, and strengthens credibility — but doing it well means producing a steady stream of blog posts, e-books, infographics, and videos, often in complex arenas. The hard part isn't volume; it's authority. SMEs supply the experience and first-hand insight that let your content say something only an insider could, which is exactly what builds trust with buyers.
It's also genuinely hard to do, which is why it's worth getting right: B2B marketers consistently rank "accessing subject matter experts" among their top content challenges in the Content Marketing Institute's annual B2B benchmarks research. The teams that solve it have a real edge over those that don't.
When AI tools can generate fluent, generic copy on any topic in seconds, generic copy stops being a differentiator. What AI can't manufacture is genuine first-hand experience — a practitioner's hard-won judgment, a real example from the field, a contrarian take grounded in having actually done the work. That's now your most durable advantage, and it pays off in two places at once:
In other words, the SME workflow below isn't just a quality nicety — it's how you produce content that survives an AI-mediated search landscape.
Before the how-to, it helps to see the collaboration from the expert's side. SME interviews go sideways for a few predictable reasons:
Over time, we found some solid ways to discover, prepare for, interview, encourage, and share subject matter expertise across different fields.
Here are five steps in leveraging subject matter expertise in B2B content marketing:
Chances are, your company or the company you’re working with has a few passionate SMEs. It could be the CEO, someone else in marketing, or the coworker sitting right next to you.
At S&G Content Marketing, our clients usually have SMEs in-house who have a hand in product and service development, and they’re usually eager to dispense knowledge with clarity and depth.
All you have to do: Listen to them.
If you don’t have in-house SMEs and you want to find subject matter experts who really know what they’re talking about, you’ll have to know where to look.
If you need external experts, search industry hashtags and use LinkedIn groups, forums, and trade publications. Social media strategist Paul Gillin recommends looking for SMEs who are already active in social channels, speak at conferences, contribute to trade publications, or lead internal seminars — they're the most likely to say yes. It also helps to remember that many experts want the exposure: contributing builds their personal brand and authority among peers, which is part of what's in it for them.
Your knowledge won't match the SME's — but before you talk, you need to ask the right questions. Ask something too basic and you'll get a basic answer, and experts have limited time, so make it count. You won't become an expert overnight, but a baseline helps. One of our clients works in cybersecurity and compliance, and it mattered that we knew those two terms aren't the same thing; learning the field's vocabulary ahead of time (encryption, tokenization, GDPR, key management, ransomware, authentication, authorization) let the conversation go deep fast.
Most SMEs aren't writers — so do the writing for them and make the interview the easy part. What works:
Then write the piece in the expert's voice and have them review it for accuracy before it goes live. One of our best interviews was with engineers at a lighting company who walked us through everything from LED technology to wavelength radiation and diurnal rhythms — 30 minutes gave us material for the next several articles.
SMEs take a real risk when they put their name to your content — for many, every published piece becomes part of a body of work they'll be judged on, so a misquote stings. When someone takes that risk for you, make sure participating pays off for them:
Do this consistently and experts stop seeing content requests as a burden — they start coming to you.
You've produced something genuinely authoritative — now make it pay off:
The biggest gains come from treating SMEs as long-term collaborators, not one-time sources. Invite them into editorial planning — they can tell you which topics are resonating with customers and which are stale. Ask for their hot takes on industry trends (summarize the research with AI first, then have them react from your company's point of view). And save every transcript and background file: they routinely spark ideas for future pieces.
To put subject matter expertise to work in your content marketing:
SMEs supply the insight, shape the piece, and lend the credibility that makes content worth trusting. In an AI-saturated search landscape, that first-hand expertise is the difference between content that gets cited and content that gets ignored.
An SME is a professional with deep, specialized knowledge of a field who supplies first-hand insight and accuracy to your content — through interviews, bylined contributions, or fact-checking — making the piece more authoritative and trustworthy.
Keep the ask small and specific (a 30-minute interview, not "write a blog post"), explain the purpose and how it benefits them, send questions in advance, and reward participation with recognition, a byline, and promotion that elevates their personal brand.
Learn enough to ask sharp questions, send them in advance, record the session (with permission), keep it to about 30 focused minutes, listen actively, and ask at the end what you might have missed. Then write in their voice and have them review for accuracy.
Where they're willing, yes. A byline or clearly credited quote with the expert's title and credentials strengthens reader trust and supports Google's E-E-A-T signals.
An SME is defined by deep expertise in a subject and can be internal or external. A consultant is typically an external hire engaged for a specific project. Many consultants are SMEs, but not all SMEs are consultants.
