Questions people ask
Q.01 What percentage of B2B buyers use AI for vendor research in 2026?
94% of B2B buyers used a large language model somewhere in their purchase research, according to Forrester's 2026 Buyers' Journey Survey of roughly 18,000 buyers — making generative AI their top vendor-research source. Separately, G2's April 2026 research found 51% of software buyers now start vendor research in an AI chatbot rather than a search engine.
Q.02 Do AI search visitors actually convert?
Yes — disproportionately. Exposure Ninja's March 2026 cross-client analysis found visitors arriving from AI assistants converted at 14.2% versus 2.8% for classic organic search, roughly a 5× multiplier, because the assistant has effectively pre-sold the recommendation before the click.
Q.03 Why doesn't AI traffic show up in analytics?
About 70.6% of AI-assistant-driven visits arrive with no referrer header (The Digital Bloom, February 2026), so they land in the 'Direct' bucket. Most teams therefore systematically under-count AI's contribution — which is why share of voice on a fixed prompt panel, not referral traffic, is the honest KPI.
Q.04 What single change most increases the chance of being cited by AI engines?
In controlled testing (Aggarwal et al., SIGKDD 2024 — the original GEO study from Princeton, Georgia Tech, IIT Delhi and the Allen Institute), adding citable statistics and quotations to a page raised its citation odds by roughly 30–40% — the strongest of all tactics tested. Empty persuasive language ranked near the bottom.
