This gap represents a significant opportunity. HubSpot shipped over 200 personalisation and AI features at INBOUND 2025, including the new Breeze Personalisation Agent, AI-Powered Email, and Segments (replacing Lists). At the same time, UK organic traffic growth collapsed 86% after Google's AI search rollout, and 54% of tracked B2B keywords now trigger AI Overviews.

The question isn't whether to invest in personalisation or AEO—it's how to do both without undermining either. That's what this guide addresses.
The Technical Tension No One Is Writing About
The core problem is deceptively simple: AI crawlers cannot see personalised content.
A Vercel/MERJ analysis of 500 million GPTBot fetches found zero evidence of JavaScript execution by any AI crawler. GPTBot, ClaudeBot, PerplexityBot—they all see only the server-rendered default HTML. HubSpot's smart content serves personalised variations via browser-side cookies and CRM data, which means AI crawlers receive exclusively your default version.
This creates a strategic imperative that most marketing teams miss entirely:
Your default content must be the AEO-optimised version, with personalisation layered on top for human visitors. Never hide critical information behind personalisation—the base must be rich enough for AI citation.
Think of it as building a house: the default content is your foundation (what AI systems index and cite), while smart content personalisation is the interior design (what makes qualified visitors feel at home). You can't have a beautiful interior without solid foundations.
Why This Matters Now: The UK Traffic Collapse
The market data makes this urgent, particularly for UK B2B companies:

54%

higher conversion rate from AI referral traffic

more revenue from personalisation (McKinsey)
The conversion story is particularly compelling. According to Semrush research, LLM visitors convert at 14.2% versus Google's 2.8%. The traffic volume is smaller, but it's dramatically more valuable—because by the time someone finds you through an AI citation, they've already compared options and learned about your value proposition.
Meanwhile, McKinsey's research shows that companies excelling at personalisation generate 40% more revenue from those activities than average players. This isn't about choosing between personalisation and AEO—it's about recognising that the companies winning in 2026 are doing both.
HubSpot's Personalisation Arsenal (What You're Probably Not Using)
HubSpot's INBOUND 2025 delivered 200+ product updates, with personalisation at the centre. If you're still relying on basic merge tags, you're leaving significant value on the table. Here's what's now available:
Breeze Personalisation Agent
Announced at INBOUND 2025 and currently in beta, this is HubSpot's first AI-native personalisation tool. It identifies audience segments most likely to respond to personalised content, then generates tailored websites and CTAs automatically. This goes far beyond rules-based smart content.
AI-Powered Email
Now in public beta, this moves beyond simple merge tags to generate unique content for every recipient using CRM data—job title, industry, recent activity, pages viewed, lifecycle stage. HubSpot's internal testing showed 82% higher conversion, 30% better open rates, and 50% lift in click-throughs versus generic emails.
Segments (Replacing Lists)
AI-driven dynamic segmentation that includes filtering for anonymous website visitors via IP-based company identification. AI-recommended segments in Marketing Hub Enterprise can discover high-potential audiences that marketers didn't know existed.
Breeze Intelligence
Powered by 200+ million company and buyer profiles from the Clearbit acquisition, it auto-fills 40+ firmographic, demographic, and technographic attributes. Free data enrichment for all paid tiers launched in August 2025. New buyer intent signals track C-level hires, product launches, partnerships, M&A activity, and growth metrics.
For a deeper dive into these capabilities, our HubSpot onboarding guide covers implementation specifics, including how to configure Breeze AI during initial setup rather than retrofitting it later.
The Dual-Optimisation Framework
Here's the practical approach that makes personalisation and AEO work together:
Step 1: Build a Comprehensive, AEO-Optimised Default
Your default content is what all crawlers—Google, GPTBot, ClaudeBot, PerplexityBot—will see and potentially cite. This version must:
- Include statistics and specific data—Princeton research found this is most effective for professional domains being cited by AI
- Answer complete questions within sections—AI systems extract discrete content chunks, so each section must make sense independently (the "Taco Bell test": can someone understand this paragraph without reading what came before?)
- Use proper heading hierarchy—H2s for main sections, H3s for subsections, with clear semantic structure
- Implement both JSON-LD and inline microdata schema—some AI engines currently ignore JSON-LD while parsing inline microdata reliably
- Include FAQ sections with concise answers—FAQPage schema is particularly effective for AI citation
Step 2: Layer Personalisation for Qualified Human Visitors
Once your default is solid, add smart content personalisation for elements that don't contain critical information needed for AI citation:
- CTAs—Personalise by industry, lifecycle stage, or previous engagement
- Testimonials and social proof—Show relevant case studies based on visitor industry or company size
- Industry-specific examples—Swap illustrative examples while keeping core information in the default
- Pricing or offer messaging—Tailor to deal stage or company tier
- Navigation or next-step recommendations—Guide visitors based on their position in the buying journey
Critical rule: Never use smart content for your core informational content—the paragraphs that explain what you do, how you do it, and why it matters. That's what AI systems need to cite you.
Step 3: Consider Dedicated Segment Landing Pages
For high-value audience segments, create fully crawlable landing pages rather than relying solely on smart content swaps. A page built specifically for biotech marketing directors will rank and get cited for biotech-specific queries, while your main page handles broader traffic.
This approach works particularly well for HubSpot Content Hub users, where creating segment-specific pages is straightforward and they automatically connect to your CRM for attribution.
Implementation Mistakes That Undermine Both Goals
Based on our experience implementing HubSpot for B2B clients, these are the most common mistakes we see:
Over-Personalising Everything
Trying to customise every element instead of focusing on 2–3 high-impact areas. This creates maintenance overhead, makes testing difficult, and often hides important content from AI crawlers. Start with CTAs and testimonials—they have the highest impact for the lowest risk.
Weak Default Versions
Teams often build personalised versions first and treat the default as an afterthought. This is backwards. Your default is now doubly important—it's what AI systems index and what anonymous visitors see. Build the default to be excellent on its own, then enhance it with personalisation.
Using Contact-Based Rules for Anonymous Visitors
Lifecycle stage and list membership rules require cookie identification—they won't work for anonymous traffic. For first-time visitors, use IP-based company identification through Breeze Intelligence, or rules based on ad source, referral source, country, or device type.
Dirty CRM Data Breaking Smart Content Rules
Personalisation is only as good as your data. Duplicate records, field mapping conflicts with Salesforce, and incomplete contact properties all undermine targeting accuracy. If you're running HubSpot alongside Salesforce, sync issues can break personalisation rules entirely—lifecycle stages that don't match, picklist misalignments, and "flip-flop" data loops from conflicting workflows.
Our HubSpot CRM guide covers data hygiene fundamentals, and for teams running both platforms, understanding the integration challenges is essential before relying on personalisation.
Schema Markup for Dual-Optimisation
Schema markup serves both traditional SEO and AI citation. For pages using the dual-optimisation approach, prioritise:
- FAQPage schema—High impact, low complexity. AI systems frequently extract FAQ content for citation.
- Article/BlogPosting schema—Essential for content pages. Include author information, publication dates, and headline.
- Organization schema—Establishes entity identity for AI systems building knowledge graphs.
- HowTo schema—Particularly valuable for process-oriented content that AI systems summarise.
- Speakable schema—Marks sections suitable for voice assistants and audio summaries.
Important: Schema must reflect your default content (what crawlers actually see), not your personalised variations. If your schema describes testimonials from a SaaS company but the crawler sees your default manufacturing testimonial, you've created a mismatch.
The "Loop Marketing" Connection
HubSpot's new "Loop Marketing" framework, announced at INBOUND 2025, places personalisation as the second core stage (Tailor) in their four-stage model: Express → Tailor → Amplify → Evolve. This signals a strategic shift from funnel-thinking to continuous personalisation loops.
The third stage—Amplify—explicitly calls out diversifying across channels including AEO. HubSpot now offers dedicated Answer Engine Optimisation tools, including a free AEO Grader that analyses brand visibility across ChatGPT, Perplexity, and Google Gemini.
The framework validates what we've been seeing with clients: the companies achieving the best results aren't choosing between personalisation and AEO. They're building systems that do both, recognising that buyers move unpredictably across channels rather than following a linear journey.
Our INBOUND 2025 coverage has more detail on how the Loop framework applies to B2B marketing strategy.
Frequently Asked Questions
Can AI crawlers see HubSpot smart content?
No. AI crawlers like GPTBot, ClaudeBot, and PerplexityBot cannot execute JavaScript, meaning they only see the server-rendered default HTML. HubSpot's smart content serves personalised variations via browser-side cookies and CRM data, so AI crawlers receive exclusively the default version of your pages.
Does personalisation help or hurt AI search visibility?
Personalisation neither helps nor hurts AI visibility directly—what matters is your default content. AI crawlers see only your default (non-personalised) content, so that version must be comprehensive and AEO-optimised. Layer personalisation on top for human visitors without hiding critical information behind smart content rules.
What's the difference between AEO and GEO?
AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) refer to the same practice: optimising content to appear in AI-generated search responses from platforms like ChatGPT, Google AI Overviews, Claude, and Perplexity. GEO is the academic term from Princeton research, while AEO is more commonly used in the industry.
How much more valuable is AI search traffic compared to traditional organic traffic?
According to Semrush research published in June 2025, AI search visitors convert at 4.4 times the rate of traditional organic search visitors. This is because AI platforms provide comprehensive information during the research phase, meaning users arrive at websites already informed and closer to making purchase decisions.
Which HubSpot tier do I need for smart content?
Smart content is available in Marketing Hub Professional/Enterprise and Content Hub Professional/Enterprise. It works across website pages, landing pages, marketing emails, CTAs (including on external pages), forms, and templates. Note that blog post smart content is technically possible but officially discouraged by HubSpot due to SEO and RSS concerns.
Making It Work: A Practical Summary
The dual-optimisation approach isn't complicated, but it does require intentionality:
- Audit your current default content. View your pages as a crawler would (disable JavaScript, use a cache-only view). Is your default version comprehensive enough to stand on its own?
- Identify high-impact personalisation opportunities. Focus on CTAs, testimonials, and industry-specific examples—not core informational content.
- Implement schema that reflects your default. FAQPage, Article, and Organization schemas are highest priority for AI citation.
- Clean your CRM data before relying on personalisation. Dirty data breaks smart content rules and creates inconsistent experiences.
- Consider segment-specific landing pages for high-value audiences. These are fully crawlable and can rank for segment-specific queries.
The companies winning in 2026 aren't choosing between personalisation and AEO—they're building systems that deliver both. With HubSpot's expanded AI capabilities and a clear understanding of how AI crawlers work, you have everything you need to execute this strategy.
