What is AI?

Everything you seem to use these days has the buzzword AI (or Artificial Intelligence) attached to it, you see it in self-driving cars and even AI Powered Robobees! But what exactly is Artificial Intelligence?

At its simplest, Artificial Intelligence is the capability of a computer system to perform tasks that typically require human intelligence.

If you think about the things a human brain can do:

  • Learn: Being able to adapt to new information and improve over time
  • Reason: Being able to use logic to solve problems
  • Perception: Being able to recognise and distinguish between images, sounds, and patterns. (Knowing a friend’s face, or understanding a language)
  • Decision Making: Being able to decide the best course of action

AI is now the field of computer science dedicated to building machines and software that mimic the cognitive functions of the human brain. In short, we are teaching machines to “think”, “learn,” and make decisions on its own.

How traditional SEO and AI results work.

All about SEO/GEO

Both Search Engine Optimisation (SEO) and Generative Engine Optimisation (GEO) are necessary in 2025 for online visibility, but they target different areas:

  • SEO: This is what we have been using for the last 2 decades; it’s the practice of optimising websites to rank high in Standard Search Engine Results Pages, often referred to as SERPs. The main strategies include keywords, backlinks, and technical health.
  • GEO: This is the new emerging practice of optimising content for AI Generative engines (ChatGPT, Perplexity, Google Gemini). It aims for brand visibility and inclusion in AI summaries, often resulting in a ‘zero click” answer for the user.

The future of SEO is going to be GEO. This does not mean that it will replace traditional SEO; instead, it will build on it, requiring content creators to be more authoritative, precise, and well-structured so that AI models can cite them as a definitive source.

How AI surfaces results.

Back in the day, simple keyword matching was all you needed. Nowadays, search engines and AI chatbots don’t just look for words — they search for meaning. When you ask a question, it’s instantly translated into a numerical “fingerprint.” The process has three main steps: Tokenisation, Embeddings, and Cosine Similarity, which together allow AI to find answers based on semantic relevance. Tokenisation The best way to explain tokenisation is to imagine you are translating a foreign language — but instead of translating vocabulary, you’re translating basic sounds. In this case, instead of sounds, a computer must convert human language into numbers. Tokenisation is the first step where AI breaks down phrases and entire sentences into the smallest possible units, known as tokens. These tokens form the computer’s vocabulary, preparing it for AI understanding.
Original Text “The cat sat on the mat.”
Tokenisation[The], [cat], [sat], [on], [the], [mat]
Once the text is broken into a list of numbered tokens, it’s ready for the next step.

Embeddings

If tokenisation is about cutting text into pieces, embeddings are about understanding what those pieces mean.

Every token, phrase, or sentence is converted into a vector,  a long list of numbers that captures its semantic meaning. These vectors live in what we call a multidimensional space, where each dimension represents a different hidden pattern learned by the model (for example: tone, topic, emotion, object type, etc.).

Think of it like this:
Every word becomes a coordinate in a giant 3D map,  but instead of three dimensions (x, y, z), AI’s maps can have hundreds or even thousands of dimensions.

For example:

“The cat sat on the mat.”
→ [0.10, 0.20, 1.20, 2.30, 1.01, ... up to 1,536 dimensions]

Now, imagine another sentence:

“The cat sat on the bed.”
→ [0.10, 0.20, 1.20, 2.12, 1.05, ...]

Notice how their coordinates are very close.
Even though “bed” and “mat” are different words, their vectors are nearby in this semantic space because the model learned from context that they appear in similar situations.

That’s how LLMs understand meaning, by proximity in vector space, not by word overlap.

How Queries Work in This Space

When you ask a question, say,

“Where is the cat resting?”
The AI converts your query into the same kind of vector.

That query vector is then projected into the same multidimensional space where all other text vectors (sentences, documents, facts) already exist.

Now, the model doesn’t search by matching words like “cat” or “resting.”
Instead, it measures the angle between your query vector and all the stored text vectors in that space, to find the ones pointing in the same direction of meaning.

This is where Cosine Similarity comes in.

Cosine Similarity

Imagine every sentence or document as a flashlight beam pointing in a unique direction in space. Your query is another flashlight beam.

Cosine Similarity measures how closely your beam aligns with others. If both beams point in nearly the same direction, the model says: “Aha, these two mean almost the same thing.”

Key points to remember:

  • It’s all about direction, not length:
    It doesn’t matter if your flashlight is tiny or huge; the AI only cares whether the beams point together.
    A short query (“best spa in Phuket”) and a long article (“Top 10 Relaxing Spas and Wellness Retreats in Phuket”) can still point in nearly the same direction — meaning they share intent.
  • The angle determines the match:
    The smaller the angle between two vectors, the higher the cosine similarity score.
    • Angle = 0° → Score = 1.0 → Perfect match
    • Angle = 90° → Score = 0.0 → Unrelated
    • Opposite direction → Score < 0 → Contradictory meaning
Cosine Similarity ScoreMeaning
1.0Perfect match in meaning (vectors point in the exact same direction).
0.8Highly relevant and closely related.
0.2Barely related, only a slight connection.
0.0Unrelated (vectors are perpendicular).

The Final Result

When you type a query into a modern search engine or chatbot, here is what happens in milliseconds:

  1. Tokenisation: Your query is broken down into numerical tokens.
  2. Embedding: The tokens are combined to create one single Query Vector that represents the semantic meaning of your search.
  3. Vector Search: The AI compares this Query Vector against the billions of pre-calculated Document Vectors using Cosine Similarity.
  4. Ranking: It instantly ranks the results from the highest similarity score (closest to 1.0) to the lowest.
  5. Result: The AI shows you the top-ranked results, giving you documents that mean what you were looking for, even if they don’t use the exact keywords you typed.

Key Actions for AI Ranking

Nowadays, ranking in the “AI Era” isn’t just about repeating keywords and building backlinks, which is still relevant, but also about creating a trusted, definitive, and structured source of information.

Doing Good SEO

Before AI can see the quality of your content, it must first be processed efficiently. The way you do this is through good seo

  • Speed and Accessibility: A fast-loading site is non-negotiable. AI crawlers have a limited “crawl budget.” If your site is sluggish with errors, the AI will spend less time on it, which can delay or prevent new content from being indexed. Ensure your site is mobile-responsive and all code is optimised.
  • Clear Information Architecture: Your website should be organised like a well-structured book. Use a clear, shallow site structure, and implement internal linking strategically. This helps the AI understand the relationship between different pages and establishes the central topic of your website.
  • Off-Page SEO- Getting relevant backlinks from a trusted source is still important; it doesn’t matter whether it is a do-follow or a no-follow kind of link, a link from a trusted source, relevant to your niche, is important.
  • Optimised On-Page Elements: Use descriptive headings (H1 to H6) to outline your content logically. Your title tag and meta description must clearly communicate the page’s core topic, acting as an elevator pitch for both the human user and the AI. 

AI models are constantly looking for the most efficient way to take in information. Content that is pre-structured for this purpose is more likely to be selected as to form the basis of an AI summary.

  • The “Snippet-Ready” Answer: The AI often attempts to provide a single, definitive answer to a user’s question.
    • Immediately follow a heading or question with a direct, 40-70-word answer in a short paragraph. You can then elaborate on this answer below it.
    • If the heading is “What is Content Delivery Network (CDN)?” the first paragraph should start: “A Content Delivery Network (CDN) is a geographically distributed group of servers that work together to provide fast delivery of Internet content…”
  • Leveraging Structured Data: Content organised into Bullet Points, Numbered Lists, or Tables is extremely easy for an AI to read, understand, and reproduce in its own answer.
    • Use lists to break down steps, features, or components. Use tables to organise complex data, comparisons, or pricing. This formatting directly maps to the way AI Overviews and Chatbots present information.

E-E-A-T Principles: For Content Creation

Experience, Expertise, Authority, and Trustworthiness (EEAT), which Google has been discussing for a long time, has become one of the primary frameworks for assessing the reliability of the content. Lets break down EEAT-

  • Experience (Show, Don’t Just Tell): This is the newest and most crucial component. It means demonstrating first-hand knowledge.
    • Include unique photos of the product being used, showcase original data from your own research, or provide case studies and personal testimonials to prove you’ve done what you’re writing about.
  • Expertise (Verifiable Qualifications): The AI seeks evidence that the author is qualified to speak on the subject.
    • Clearly link to the author’s bio, listing relevant degrees, certifications, years of professional experience, or awards. On a cooking site, the author should be a chef; on a legal site, an attorney.
  • Authority (External Validation): This is your digital reputation, built through mentions and links from other highly-trusted sources.
    • Actively seek mentions and backlinks from authoritative, relevant websites. Build an “As Seen On” or “Featured In” section on your site to signal this authority to the AI.
  • Trustworthiness (Accuracy and Security): This covers the site itself and the accuracy of its facts.
    • Action: Ensure you have a functioning SSL certificate (HTTPS). Clearly cite all external sources using in-text links. Have clear policies (Privacy Policy, Terms of Service). On e-commerce sites, make sure product pricing and availability are accurate.

Uniqueness and Conversational Tone

The AI’s goal is to synthesise information from across the web. To truly stand out, your content must offer something new that the AI cannot simply combine from other sources.

  • Provide Unique Value: This is the antidote to AI-generated content saturation. The AI wants a reliable source for facts, not just regurgitation.
    • Focus on Original Research (surveys, proprietary data), First-Hand Commentary (expert opinions, unique analysis), or Case Studies that only you have access to. If 100 pages say the same thing, the AI is likely to choose one with unique data.
  • Write with Conversational Fluency: AI models are trained on natural human language. The more your writing matches how people speak, the easier it is for the AI to process and determine its relevance to a spoken query.
    • Use a natural, friendly, and non-robotic tone. Avoid overly formal or archaic language. Use Long-Tail Keywords (phrases that resemble actual questions, like “how do I cook steak medium rare”) within your headings and content.

Summarising

Artificial Intelligence has transformed how information is created, understood, and discovered. Search engines no longer simply match keywords;  they interpret intent, meaning, and trust. As we move further into the AI-driven era, success will depend on how well we combine traditional SEO foundations with new GEO strategies. Creating content that is fast, structured, credible, and truly insightful isn’t just good practice; it’s how we help both humans and machines understand our value. The future of visibility belongs to those who write for meaning, not just for search.
