Seven questions your buyers are asking AI before they call you

Maybe your pipeline didn't completely dry up — it went quiet in a specific way: fewer first calls, and the buyers who do show up arrive with a shortlist already formed and opinions already set. That's a visibility problem, masked as a demand problem. Before a technical buyer ever fills out your form, they've run their hardest questions through ChatGPT, Gemini, or Claude, and the answer they got either included you or it didn't.

At illi (B2B brand engagement), we've spent the past year mapping how industrial, manufacturing, construction, and B2B technology buyers use AI search, and where brands disappear from the answer. One finding from the original Princeton research on generative engine optimization stuck with us: content built with citations, statistics, and attributed quotes can lift visibility in AI answers by up to 40 percent (Aggarwal et al., arXiv:2311.09735). The brands getting cited aren't louder, they are structured to be quotable.

Here are the seven questions we see buyers asking AI first, and what each one means for whether you make the answer.

1. "Who are the top suppliers for [my application]?"

This is where shortlists form now. AI engines build vendor lists from listicles, review sites, and trade coverage, not from your homepage. If the roundups in your category don't mention you, the engine has no reason to either. The move: earn placements in the third-party lists AI already trusts, and publish comparison content of your own so there's something citable to pull from.

2. "Compare [you] vs [your competitor]."

Buyers used to build this table themselves. Now the engine builds it in eight seconds, from whatever it can find. If the only head-to-head content in your category was written by your competitor, you're being compared on their terms. Honest comparison pages, including where you're not the right fit, are among the most-cited content formats in B2B.

3. "What are the risks of switching from [the incumbent]?"

This is the person on the buying committee who owns continuity and gets blamed for disruption. They're asking AI because it feels safer than asking a salesperson. If your content never addresses switching risk, downtime, and integration honestly, the engine answers with generic caution, and caution favors the incumbent every time.

4. "What do customers say about [you]?"

Engines treat third-party voices as more credible than your own. Reviews, case studies with named customers, trade press, even forum threads. A brand with strong work and no public proof reads to AI the same way it reads to a skeptical engineer: unverified. The fix isn't more claims, it's more attributable evidence from people who aren't you.

5. "What certifications and standards apply to [this product category]?"

Compliance questions carry some of the highest intent in industrial buying, and they're often asked by the person holding veto power. If your certification and standards content lives inside a PDF spec sheet, it's invisible to the engine. Clear, current, plain-language compliance pages get cited, and they put you in the room before the first call.

6. "How do I justify the cost of [this solution] to leadership?"

Once a buyer finds you they still have to sell you internally, and they're asking AI to help build that case. Content that hands them ROI framing, total-cost math, and a story they can defend up the chain gets carried straight into their board deck. Most industrial brands skip this content because it doesn't feel like marketing. That's exactly why it works.

7. "What questions should I ask a [category] vendor?"

The buyer asking this is preparing to sit across from you. If your content shaped their checklist, you set the criteria before the meeting started. If a competitor's content shaped it, you're answering their questions. Publishing a genuinely useful buyer's checklist feels like giving away the test. It is. You want to be the one who wrote it.

What the seven have in common

The buying conversation starts before you're in it, and AI decides who's at the table based on what it can parse, verify, and cite. That's the whole case for generative engine optimization (GEO): structuring your expertise so the engines answering your buyers can find it, trust it, and name you. And because AI downranks content older than about six months, this isn't a launch, it's a discipline.

If you want to know how your brand shows up today, run these seven questions yourself. Type your category into ChatGPT and see who gets named. If it stings, you just found your content plan.
