How B2B Buyers Use AI Search to Choose Software
Buyers use AI assistants to build a shortlist, compare vendors on price and fit, and check reviews. Each stage has its own kind of prompt, and its own chance to be left out.
How do B2B buyers use AI search to choose software?
B2B buyers use AI assistants to name the options in a category, narrow them to a shortlist that fits their team size and stack, compare two or three vendors on price and features, and check what other users say. Most still verify on vendor sites and review sites before they book a demo.
What do buyers ask at each stage?
Buyers ask different questions at each stage, and the stage decides which of your pages can be cited. Early prompts name a problem, middle prompts name constraints, and late prompts name vendors. The examples below are realistic prompts written for this guide, not quotes from real buyers.
| Stage | Example prompt | Pages that tend to help |
|---|---|---|
| Discover | “How do small SaaS support teams handle ticket volume without hiring?” | Explainers, guides, original data |
| Shortlist | “Best help desk for a 4-person team on HubSpot, under $50 per agent” | Pricing, integrations, ‘who it’s for’ pages, review sites |
| Compare | “Fabrikam Desk vs Litware Help for a B2B SaaS team” | Honest comparison pages, feature tables, review sites |
| Validate | “Problems people report with Fabrikam Desk” | Reviews, forums, changelog, support docs |
| Justify | “Help me write a business case for a new help desk” | ROI pages, case studies with numbers |
What does the survey data say?
The survey data says AI answers now shape which vendors make the list. G2’s March 2026 survey of 1,076 B2B software decision makers found 51% start research with AI chatbots more often than Google, up from 29% a year earlier, and 69% changed their planned vendor after AI guidance.
| Finding | Share |
|---|---|
| Rely on AI chatbots for software research | 71% |
| Start research with AI chatbots more often than Google | 51% |
| Chose a different vendor than planned because of AI guidance | 69% |
| Say AI chatbots sped up their purchase decision | 80% |
| Say review sites give the most confidence in a choice | 45% |
| See inaccurate AI recommendations often or very often | 64% |
Do buyers trust what AI tells them?
Buyers use AI answers but check them. In the same G2 survey, 64% said they see inaccurate recommendations often or very often, and review sites were the signal that gave the most confidence. That makes accuracy a sales problem: a wrong price or missing integration in an answer can end a deal you never knew about.
How to correct what answers say about you is covered in why your SaaS isn’t showing up in AI answers.
Answer the buyer’s question before they ask it.
If a buyer can’t find your price, your integrations or who you’re for in one place, an AI answer will fill the gap from somewhere else.
What should a SaaS team do with this?
Write down the ten questions your last five customers asked before buying, turn them into prompts for each stage, and check the answers monthly. Then make sure every fact those prompts need, like price, integrations and customer size, is stated plainly on a page you control.
The prompt method is on measuring AI search visibility. Building a clear ideal customer profile first helps; see ideal customer profile.
