This article explains how AI and ML influence SEO, why it matters for marketers, and how businesses can adapt their strategies to stay competitive.
What Are AI and Machine Learning in SEO?
AI refers to smart technology that can simulate human intelligence, while machine learning is a type of AI that allows computers to learn from data and improve their decisions over time. In SEO, AI helps search engines understand:
- The intent behind search queries,
- The quality and usefulness of content,
- And how to personalise results for users.
Google and other search engines now rely heavily on these technologies to make search faster, more accurate, and more human-like (Google, 2024).
Key Milestones in Google’s Use of AI
Google has introduced several major AI-based technologies over the years:
- RankBrain (2015): Google’s first machine learning system that helped interpret search queries more intelligently.
- BERT (2019): Improved Google’s ability to understand how words in a sentence relate to each other.
- MUM (2021): A powerful AI model that understands multiple types of content (text, images, video) and languages simultaneously.
- Gemini (2024): Google’s most advanced large language model (LLM), now used in AI Overviews, offering direct answers to user queries (Search Engine Journal, 2024).
These developments show a clear shift toward understanding meaning and context, not just words.
How AI Affects Keyword Strategy
In traditional SEO, choosing the right keywords was the main strategy. Now, AI-powered algorithms look at search intent, topic relevance, and semantic meaning.
What’s Changed in 2025:
- Keyword stuffing is penalised.
- User intent (informational, transactional, navigational) matters more.
- Long-tail keywords and natural phrasing are crucial.
Practical Tip: Use tools like AnswerThePublic and AlsoAsked to discover real questions people ask. Group your keywords by topic clusters and ensure each page satisfies a specific user need.
Creating Content for AI-Powered Search
Google’s AI models are trained to reward content that aligns with E-E-A-T: Experience, Expertise, Authoritativeness, and Trustworthiness (Google Search Central, 2024). That means content must not only be accurate but also genuinely useful.
Best Practices:
- Write clear, focused articles that answer user questions.
- Include author bios, credentials, and sources.
- Use structured formatting (H2, H3 headings, bullet points) for better readability.
Helpful Tools:
- Surfer SEO: Analyses the top-ranking pages and suggests how to improve your content.
- MarketMuse: Helps plan and optimise your content strategy based on topic gaps.
Technical SEO and AI
AI also plays a huge role in evaluating your website’s performance from a technical perspective.
Key Areas to Focus On:
- Core Web Vitals: Google uses metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS) to assess page experience.
- Mobile Usability: Most searches are mobile-first, and Google rewards mobile-friendly websites.
- Schema Markup: Adding structured data helps search engines better understand your content.
Recommended Tools:
- PageSpeed Insights: Measures and suggests improvements for site speed.
- Google Search Console: Tracks your site’s performance, indexing, and mobile usability.
- Schema Markup Generator: Helps implement rich snippets and other structured data.
Personalised Search Results
AI makes it possible for search engines to personalise results based on:
- Location
- Device used
- Past searches
- Browsing behaviour
This means the same keyword can return different results for different people.
What You Can Do:
- Use Google Business Profile to optimise local SEO.
- Tailor content by region or device type.
- Aim for rich results like featured snippets or FAQs to capture user attention regardless of position.
The Rise of Voice Search
In 2025, millions of people use voice assistants to search. AI models like Google Assistant, Alexa, and Siri have reshaped how users ask questions.
SEO Tips for Voice Search:
- Optimise for long-tail and conversational phrases.
- Use Q&A formats (e.g., “What is the best coffee shop near me?”).
- Include FAQ schema on your pages.
Recommended Tools:
- Frase: Helps create content based on common user questions.
- Semrush Keyword Magic Tool: Finds natural, question-based keywords.
AI-Generated Content: Should You Use It?
Content writing tools like ChatGPT, Jasper, and Writesonic are widely used in 2025. Google has clarified that AI-generated content is acceptable as long as it’s helpful and original (Google Search Central, 2024).
How to Do It Right:
- Use AI for drafting, but always edit and add insights.
- Fact-check all information.
- Avoid generic, duplicate content.
Content Checking Tools:
- Originality.AI: Detects AI-generated or plagiarised content.
- Copyscape: Checks for duplicate web content.

- Understanding search intent,
