The next evolution of search has already started

For more than two decades, marketing leaders have focused on one primary goal when it comes to digital visibility - ranking in Google, appearing on the first page of their search results.

Search Engine Optimisation (SEO) became a cornerstone of digital marketing strategies, helping businesses attract website visitors through organic search. Success was measured by rankings, clicks and traffic.

Today, however, search behaviour is changing. More people are using AI platforms such as ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews to research suppliers, compare products and find answers to complex business questions.

How ai is changing searchInstead of reviewing pages of search results, users increasingly receive direct recommendations, summaries and comparisons generated by AI. For CMOs and marketing leaders, this shift represents more than another search trend. It signals a fundamental change in how buyers discover, evaluate and shortlist potential vendors.

The question is no longer:

"How do we rank higher?"

It's becoming:

"Will AI recommend us when potential customers ask for solutions?"


What is AEO?

Answer Engine Optimisation (AEO) is the practice of creating and structuring content so AI systems can easily understand, trust and reference it when generating answers. Traditional SEO focuses on helping content rank in search results. AEO focuses on helping your content become part of the answer itself.

When a prospect asks ChatGPT for software recommendations, requests a vendor comparison from Gemini or asks Perplexity for advice on solving a business challenge, the AI must determine:

  • Which sources are relevant
  • Which information is trustworthy
  • Which companies deserve inclusion in the response

AEO increases the likelihood that your expertise, content and brand are included in those answers.


Why AEO matters for marketing leaders

The buyer journey is changing. A few years ago, a prospect researching CRM software might have searched:

"Best CRM software."

Today, they are more likely to ask:

"What's the best CRM for a growing SaaS company with a small sales team in Europe?"

Or:

"Compare HubSpot, Salesforce and Pipedrive for a business with fewer than 20 employees, plus check which has the best marketing automation included."

These questions are:

  • Longer
  • More specific
  • More conversational
  • More focused on outcomes

Rather than presenting links, AI platforms provide direct recommendations and summaries. This means AI is increasingly shaping purchasing decisions before prospects ever visit a website. For CMOs, that changes the visibility challenge entirely.

If your business isn't appearing in AI-generated answers, you may be absent from a critical stage of the buying process.

If your business is being cited and recommended, you're influencing decisions earlier than competitors.


How AI search differs from traditional SEO

While SEO and AEO are closely connected, they are not the same.

Traditional SEO Prioritises:

  • Rankings
  • Organic traffic
  • Keyword targeting
  • Search engine results pages (SERPs)

AEO Prioritises:

  • Answer visibility
  • Topic authority
  • Content clarity
  • AI trust signals
  • Brand inclusion within generated responses

The objective shifts from:

"Can users find our website?" To: "Can AI confidently recommend our expertise?"


How AI systems decide what
content to use

3 pillars of ai content selectionAlthough each AI platform operates differently, most rely on three core signals.

Relevance

AI systems are designed to answer specific questions. Content that directly addresses customer challenges performs better than vague marketing copy. The more precisely content solves a problem, the easier it is for AI to use.

Structure

AI models favour content that is easy to interpret.

This includes:

  • Clear headings
  • Logical content hierarchy
  • Definitions
  • FAQs
  • Step-by-step explanations
  • Comparison tables

Well-structured content helps AI understand context and meaning.

Authority

Trust matters more than ever. AI providers are under growing pressure to surface reliable information and minimise misinformation - offpage reputation is valued more than ever!

As a result, AI systems often favour sources (owned and earned) that demonstrate:

  • Expertise
  • Experience
  • Credibility
  • Industry recognition

This is one reason digital PR and thought leadership are becoming increasingly important in AI visibility strategies. AI visibility is not only a content challenge. It's a credibility challenge.


Why many brands are invisible in AI search

Many organisations assume that being a strong business automatically leads to visibility. In reality, AI often struggles to understand companies whose websites were built primarily around internal messaging rather than customer questions.

Common issues include:

  • Generic content
  • Weak positioning
  • Thin product pages
  • Limited thought leadership
  • Poor topic coverage
  • Feature-focused messaging

A common mistake is focusing on product functionality while buyers focus on outcomes.

Businesses describe features. Customers ask questions. How can I…

  • Reduce costs
  • Improve efficiency
  • Increase productivity
  • Accelerate growth

The brands gaining visibility in AI search are those that connect their solutions directly to customer problems.


Key takeaways for CMOs

Answer Engine Optimisation is not replacing SEO.

It's expanding the visibility landscape. As AI-powered search continues to influence buying decisions, marketing leaders need to think beyond rankings and traffic.

The brands that win will be those that:

  • Build authority within their category
  • Publish genuinely useful content
  • Structure information for AI understanding
  • Demonstrate expertise consistently
