CRO and AEO: Optimise for Humans and AI Search

Search is changing fast.

With the rise of AI-powered search engines and answer tools, users are no longer scrolling through lists of links. They are asking direct questions and expecting quick, accurate answers.

This shift is driving a new form of SEO called Answer Engine Optimisation, or AEO. At the same time, marketers are still focused on improving conversions through CRO, or Conversion Rate Optimisation.

The good news is that both share the same foundation — clear, user-focused content and frictionless design.

This guide explains how optimising your website for real people also improves your visibility in AI search results, and how CRO and AEO can work together to create content that both humans and machines understand.

What Is Answer Engine Optimisation

Answer Engine Optimisation is the practice of structuring content so that AI-driven search engines such as Google’s Search Generative Experience, ChatGPT, and Microsoft Copilot can easily find and summarise it as an answer.

Instead of ranking as one of many search results, AEO helps your brand become the source that answer engines pull from directly.

How AEO differs from traditional SEO

Traditional SEO focuses on ranking for keywords.
AEO focuses on answering questions clearly and concisely.

Traditional SEO targets click-through rates.
AEO targets visibility inside AI-generated summaries.

Both are essential, but AEO puts clarity, structure, and credibility at the centre of your content strategy.

What Is CRO and Why It Still Matters

Conversion Rate Optimisation focuses on improving how effectively your website turns visitors into leads or customers.

CRO looks at your design, content, and user experience to remove friction and guide visitors toward action — whether that means filling out a form, booking a demo, or making a purchase.

A well-optimised website converts visitors faster because it gives people what they are looking for without making them work for it.

And that simplicity is exactly what AI-driven search engines reward too.

Why CRO and AEO Belong Together

CRO and AEO might sound like two different disciplines, but they share the same goal: to make information easier to find, understand, and act on.

• CRO helps users make decisions.

• AEO helps AI understand your answers.

Both benefit from the same core principles: clear language, structured information, and strong intent signals.

When you design for humans first, AI engines recognise and prioritise your content as trustworthy and relevant.

The shared foundation of CRO and AEO

1. User-first design that reduces cognitive load

2. Clear and structured content that follows logical hierarchy

3. Mobile and accessibility optimisation

4. Fast page load speed and clean code

5. Verified, credible, and context-rich information

A site that converts well also performs well in answer engines because both audiences — humans and AI — want clarity and confidence.

Step 1: Focus on Clarity and Readability

AI search systems rely on natural language processing to understand your content. That means writing in a clear, direct, and human tone helps both readers and algorithms.

How to improve clarity

• Use short sentences and simple vocabulary.

• Write in a conversational tone.

• Break complex ideas into digestible sections.

• Use subheadings and bullet points for scannability.

• Start answers with the most important information.

If your content can help a busy executive find what they need in seconds, it will also help an AI model interpret it accurately.

Digitalscouts follows this principle in every blog and landing page: simplicity over jargon, structure over complexity.

Step 2: Use Structured Data and Logical Headings

Structure is how search engines and AI models understand relationships between pieces of content.

For AEO

Use clear headings that mirror user questions. For example:

• What is HubSpot CRM

• How does marketing automation improve ROI

• Why is CRO important for B2B websites

This question-based format makes your content more discoverable in answer engines.

For CRO

Headings and structure guide readers visually. A logical flow keeps visitors on the page longer, which improves engagement metrics and trust.

When your website layout and content structure work together, both people and algorithms can navigate it easily.

Step 3: Write for Questions, Not Keywords

AI search behaviour is conversational. Users no longer type “best B2B CRM.” They ask, “What is the best CRM for a growing B2B business.”

AEO optimisation means writing content that anticipates and directly answers these natural-language questions.

How to apply this

• Research questions your audience is asking in forums, customer calls, or chat logs.

• Use these questions as H2 or H3 headings.

• Provide a short, clear answer immediately below each one.

CRO benefits too. When readers find direct answers, they stay longer, engage deeper, and are more likely to convert.

Your content becomes both informative and persuasive.

Step 4: Design for Engagement and Flow

Answer engines favour websites with strong engagement signals because they suggest users find the content valuable.

CRO improvements like simplified navigation, clear CTAs, and interactive design not only increase conversions but also improve engagement metrics such as time on page and bounce rate — factors AI systems often consider in ranking visibility.

CRO improvements that support AEO

• Place CTAs contextually within informative content rather than at the bottom

• Use visuals such as charts and infographics to explain data

• Keep forms short and relevant

• Optimise mobile layouts for quick scanning and clicking

User experience tells AI that your site provides a positive interaction, which strengthens its authority score.

Step 5: Make Your Content Credible and Contextual

AI-driven engines prioritise reliable sources. To appear in AI summaries, your content needs to show expertise, authority, and trustworthiness.

Strengthen credibility

• Add author names and credentials

• Include links to reputable sources

• Reference real data and research

• Keep information updated regularly

Strengthen context

Use supporting content clusters that show depth around a topic. For example, a main page about “Answer Engine Optimisation” could link to related topics like “AI Search Behaviour” or “Structured Data in HubSpot.”

This internal linking signals both expertise and context, which improves visibility in AI-generated results and keeps readers exploring your site.

Step 6: Combine CRO Insights with AEO Data

CRO uses behavioural analytics to see how users interact with content. AEO uses search data to see how users discover it. Together, these insights reveal where and why visitors drop off or convert.

Combine metrics such as

• Page views and scroll depth

• Form completion rates

• Dwell time and exit rate

• Keyword ranking and click-through rates

• AI visibility or mention in answer boxes

When viewed together, you can see how design and content changes affect both discovery and conversion.

Digitalscouts often builds RevOps dashboards that combine CRO and AEO data to measure performance across the full customer journey.

Step 7: Optimise for Voice and Conversational Search

Voice search and conversational AI assistants depend on natural, spoken language.

How to adapt

• Write as if answering a spoken question.

• Use full sentences rather than fragments.

• Incorporate phrases like “the best way to” or “how to improve.”

• Provide short, direct answers early in each section.

Optimising for conversational search not only helps AEO visibility but also improves your CRO messaging because it sounds more natural and approachable to human readers.

Step 8: Test and Iterate Like a CRO Expert

AI algorithms change frequently, but user behaviour is consistent: people want fast, clear, and trustworthy answers.

How to maintain both CRO and AEO success

• Review analytics monthly for traffic and conversions

• Track changes in AI visibility or answer box mentions

• Update content regularly with fresh examples and data

• Continue A/B testing CTAs, headlines, and form placements

Iteration keeps your site aligned with both user expectations and evolving AI search behaviour.

Digitalscouts helps clients build long-term CRO and AEO programs that adapt over time rather than rely on one-time fixes.

The RevOps View: Why This Matters Beyond Marketing

For operations and sales leaders, AEO and CRO are not just marketing strategies. They are tools for predictable growth.

When your marketing content answers questions clearly, sales spends less time explaining basics. When your website converts efficiently, operations has cleaner data and better forecasting.

RevOps alignment ensures all three teams work from the same system — content built for discovery, engagement, and measurable conversion.

HubSpot’s CRM and CMS make this integration easy. They connect content performance with lead tracking and automation, giving you full visibility from search to sale.

Common Mistakes to Avoid

• Writing for algorithms instead of people

• Stuffing too many keywords into copy

• Overcomplicating design with distractions

• Ignoring mobile and accessibility needs

• Forgetting to connect CRO outcomes to revenue

Avoiding these pitfalls ensures your optimisation efforts stay focused on clarity and value, not just traffic.

Bringing It All Together

CRO and AEO are two sides of the same strategy. Both reward content that is clear, helpful, and designed for real users.

When you write for humans first, AI-powered search engines recognise and amplify your content. And when your website converts easily, those visitors become customers faster.
