Here’s a scene playing out across your competitive landscape right now. Your ideal customer — a VP of Revenue at a 200-person SaaS company — opens ChatGPT and types: “What’s the best revenue intelligence platform for a Series B company with a PLG motion?”
In three seconds, they get back a curated, confident answer. Three to five vendors are named. Comparisons are drawn. A recommendation lands. Your buyer never visits Google. Never clicks a blog post. Never finds your carefully-crafted SEO content.
And if your brand isn’t in that answer — you simply don’t exist.
of B2B buyers now start purchasing research in an AI chatbot — not Google
chose a different vendor than originally planned — based on AI chatbot guidance
higher conversion rate — AI-referred visitors vs. traditional organic search
One in three B2B buyers purchased from a vendor they’d never heard of because an AI recommended them. That’s not a future scenario — that’s April 2026 data from G2 's survey of over 1,000 software buyers.
"The Yellow Pages compressed the market into the big book. Google compressed it into the first page. Now, AI chatbots are compressing it into a single answer."
Chief Innovation Officer, G2 · Executive Fellow, Harvard Digital Data Design Institute
That compression is your new competitive reality. The question is no longer "do we rank on Google?" The question is: when a buyer asks AI about your category, are you the answer?
BrightEdge's 12-month analysis (Feb 2025–Feb 2026) found AI Overviews now trigger on 48% of all tracked queries — a 58% year-over-year increase. For B2B technology the trigger rate jumped from 36% to 82%.
But here’s what most doom-and-gloom coverage misses: the traffic didn’t disappear. It moved. AI platforms generated 1.13B referral visits in June 2025 — a 357% increase year-over-year. AI-sourced sessions surged 527% in H1 2025 .
"By 2028, AI agents will mediate 90% of B2B purchases. Citation authority in agent retrieval data determines shortlist presence — and there is no recovery mechanism for brands outside that retrieval."

Imagine you’re a researcher asked to write a 200-word summary on “the best revenue intelligence tools for Series B SaaS.” You have 10 minutes and the entire internet. You’d cite content that answers directly, contains specific verifiable data, comes from a recognised authority, and can be extracted cleanly as a standalone paragraph.
AI language models make the same call. The academic term is extractability. Here’s what the research actually says moves the needle:
“Best RevOps for PLG SaaS”
GPTBot / ClaudeBot fetch candidates
G2, LinkedIn, press recognition?
Clean paragraph lift? Schema present?
Your brand in the answer
The seminal research comes from Princeton University, IIT Delhi, Georgia Tech, and the Allen Institute for AI. Their paper GEO: Generative Engine Optimization (KDD 2024) tested 9 tactics across 10,000 queries. What actually moves the needle:
Brand search volume is the strongest predictor of LLM citations — 0.334 correlation, outweighing traditional backlink signals. Digital Bloom, 2026 Building brand awareness and building AI visibility are now the same motion.

Each AI platform has its own crawl priorities. Google rankings do not transfer to AI visibility. Semrush, 2026 ↗
| AI Platform | Primary Source Signal | Bot to Allow | Top Schema |
|---|---|---|---|
| Bing index + web crawl | GPTBot, ChatGPT-User | FAQPage, Article, HowTo | |
| Own index + Brave Search | PerplexityBot | Organization, WebPage | |
| Google index | Googlebot, Google-Extended | FAQPage, HowTo, Article | |
| Brave Search grounding | ClaudeBot, anthropic-ai | Article, Organization | |
| Bing (IndexNow priority) | Bingbot | All schema via Bing | |
| X platform + web crawl | Grok crawler | Organization, Article |
Gets pages ranked in Google’s traditional blue-link results. Still necessary — Google retains ~90% of search market share — but no longer sufficient for full-funnel B2B visibility.
Gets your content extracted and cited in AI-generated answers. Focuses on schema markup (FAQPage, HowTo, Article), extractable content blocks, and answer-first page formatting.
The broader science of structuring content so LLMs cite it when generating responses from training data and web retrieval. Covers entity building and cross-platform coherence.
A brand fully optimised across all 6 AI platforms. This is what citedby is built to get you to.
A prioritised, effort-ordered action plan for B2B revenue leaders. Start Step 1 today — see citation results in as little as 2 weeks.
You can’t fix what you can’t measure. Get a citedby baseline across four dimensions: AI bot access, schema markup presence, content extractability, and cross-platform entity coherence. The audit tells you exactly which AI bots can crawl your site, how many of your buyer’s questions you currently answer, and which competitors are cited instead of you.
In our audits of 8,000+ brands, the majority of B2B SaaS sites inadvertently block at least one major AI crawler — making them completely invisible to that platform’s recommendations.
If AI bots can’t crawl your site, nothing else matters. Check that none of the following are blocked in your robots.txt:
robots.txt — Required AI Bot Permissions
Also check for Client-Side Ghosting: React / Next.js sites rendering via JavaScript serve a blank <div id="root"> to AI crawlers. Fix with SSR that delivers 300–500 words of real HTML on first load.
Schema markup explicitly tells AI systems what your content is about. Without it, AI has to infer your content's structure — and frequently skips your page entirely. Missing schema is the #1 blocker in citedby audits, ahead of content quality, backlinks, and page speed combined.
Prioritise these schema types in order:
JSON-LD — FAQPage Schema Template
app/robots.ts + app/sitemap.ts + metadata exports per route covers AI crawlability, sitemap discovery, and per-page schema in the App Router.Lead with the answer. Every key page should open with a direct 40–60 word answer to the question it addresses. This is Bottom Line Up Front (BLUF) — the structural format AI extracts from most readily.
