I created this guide for CMOs and Marketing Directors in complex B2B to understand how AI systems interpret your content - and what's actually happening when procurement teams, engineers, and executives use AI to research vendors.
If you're new to AI visibility, start here.
What is AI visibility?
AI visibility is how well AI systems understand, represent, and trust your content.
When buyers use ChatGPT, Perplexity, or Google AI Overviews to research vendors, AI systems interpret your website to answer their questions. That interpretation determines whether you appear in responses, how you're described, and whether AI trusts your content enough to cite you.
This isn't about rankings. It's about interpretation.
Most companies think they need more content. They're wrong. AI doesn't care about content volume - it cares about structural interpretation. Publishing 50 blog posts whilst homepage entity conflicts persist creates noise without fixing the core issue.
Can AI extract what you do from your homepage? Does it understand how your products relate? Can it map your capabilities to buyer needs? Does it trust your technical claims enough to mention you?
If AI systems can't interpret your content structure clearly, buyers filter you out before they ever visit your website.

SEO vs AI visibility: the strategic shift
| Dimension | SEO | AI visibility |
|---|---|---|
| Objective | Earn clicks and traffic | Earn citations in AI answers |
| Core signal | Keywords, backlinks | Structured entities, E-E-A-T |
| Success metric | Rank position | Citation accuracy and frequency |
| Content format | Blog posts, gated PDFs | Modular, parseable answers |
| Output | Page views | Vendor shortlist inclusion |
Legacy SEO treats search as a destination. AI visibility treats search as a distribution layer for trusted facts.
Why it matters now
AI visibility matters because buyers already use AI to research, compare, and shortlist vendors before making contact.
This is happening now in B2B:
Procurement teams ask AI to build vendor lists before issuing RFPs. "List qualified suppliers of industrial wastewater treatment systems." AI provides 8-12 companies. If you're not in that list, you don't receive the RFP.
Engineers use AI to understand technical approaches before contacting suppliers. "Compare injection moulding vs compression moulding for PEEK components." AI explains both approaches and mentions specific manufacturers. If AI doesn't mention you, engineers don't know you offer that capability.
Executives ask AI for market landscapes before engaging vendors. "Who are the leading advanced materials suppliers for aerospace?" AI describes the market and names 6-8 companies. If you're not named, you're not in consideration.
This filtering happens pre-contact. Before website visits. Before sales conversations. Before traditional marketing metrics register the lost opportunity.
If AI systems misunderstand your business, your customers never reach you.
In the next 6-12 months, 60-70% of industrial B2B supplier research will shift through AI systems. Companies building AI visibility now secure 18-month discovery advantage over competitors still optimising for human search.
The market reality: 77% of B2B purchases are classified as "very complex" (Gartner), 74.6% of deals take over four months to close (MarketingCharts), and only 48% of digital initiatives meet targets (Gartner 2024). For industrial companies with lean marketing teams, these pressures collide: long sales cycles now compete where AI determines visibility before humans engage.
We ran a pilot with Victrex, a leader in advanced materials - analysing pages with traction but near-zero AI visibility. Within 30 days: 52% increase in search visibility, 32% more new users, 440% increase in CTA conversions. The diagnostic found 47 specific fixable issues. Each one had a surgical fix.
The three pillars
AI visibility depends on three interconnected factors:
1. LLM parsability
Can AI systems understand your content structure?
LLM parsability is how easily AI can extract meaning from your pages. If content is cryptic, ambiguous, or poorly structured, AI cannot interpret what you do, how products relate, or which problems you solve.
(This surprises people, but the most sophisticated companies often have the worst parsability - because technical teams assume everyone understands their domain language. They don't.)
Common parsability problems:
- Jargon without explanation
- Cryptic product names without descriptive text
- Complex information locked in PDFs
- JavaScript-heavy navigation AI cannot follow
- Inconsistent terminology across pages
When AI cannot parse your content, it cannot represent you accurately.

2. Semantic density
Does your content build depth and confidence?
Semantic density is how much concentrated, coherent information you provide on specific topics. Thin single pages create low confidence. Deep interconnected clusters build trust.
AI systems need depth to develop confidence. A 200-word page on "advanced composites" gives AI nothing to work with. Eight interconnected pages covering materials science, applications, specifications, and case studies create semantic density AI can trust.
Without semantic density, AI defaults to competitors with deeper coverage.

3. Structural clarity
Can AI map your entities and relationships?
Structural clarity is how clearly AI can identify what you are (entities), what you offer (capabilities), and how things relate (relationships).
If your homepage says "consulting firm", product pages say "software company", and about page says "research organisation", AI cannot classify you correctly. If product relationships are unclear, AI cannot map your portfolio. If terminology varies across pages, AI cannot build entity coherence.
Structural clarity determines whether AI understands your business accurately.
Common symptoms of poor AI visibility
I've diagnosed these patterns across 40+ AI visibility assessments. The symptoms are systematic:
AI misunderstands what you do When you ask ChatGPT or Perplexity "What does [your company] do?", the answer is wrong, vague, or focusses on outdated capabilities.
Technical expertise trapped in PDFs Your datasheets, specifications, and technical content are in PDF format. AI systems cannot read or cite this content.
Contradictory messages across pages Different pages describe the same capability differently. Homepage positioning conflicts with product page messaging. AI sees contradictory signals and cannot determine accurate classification.
Thin content on core topics Your most important capabilities have single pages with 200-300 words. Competitors have comprehensive multi-page clusters. AI trusts their depth over your thin coverage.
AI doesn't mention you When asked category questions like "Who makes industrial polymers?", AI doesn't mention your company even though you're an established player.
Misclassification in summaries AI describes you as wrong category or focusses on capabilities you de-emphasised years ago because legacy content still overweights domain classification.
In our Victrex audit, these exact patterns appeared: technical content didn't surface in AI search, product pages buried commercial value, CTAs asked for demos before buyers understood fit. The compound effect of fixing these changed their pipeline trajectory.
If you recognise these symptoms, you have structural issues affecting AI interpretation.
What affects AI visibility most
Three factors create the biggest impact:
Content structure (not volume)
Adding more content doesn't improve AI visibility if structure remains broken.
AI systems interpret content architecture - how pages relate, how entities connect, how topics cluster. Publishing 50 blog posts whilst homepage entity conflicts persist creates noise without fixing interpretation.
Structure matters more than volume.
Entity clarity (not keyword density)
Optimising keywords doesn't help if AI cannot extract entities.
AI needs clear entity extraction to understand what you are, what you offer, and which problems you solve. Cryptic product names, inconsistent terminology, and ambiguous positioning prevent entity recognition regardless of keyword optimisation.
Entity clarity matters more than keyword frequency.
Cluster coherence (not individual pages)
Optimising isolated pages doesn't build the semantic density AI requires.
AI interprets topical coverage across interconnected pages. Single optimised pages create weak signals. Comprehensive clusters (8-12 pages on a topic) build semantic mass that creates confidence and trust.
Cluster coherence matters more than individual page quality.
