2) AI and Generative Search
AI is changing SEO in a big way:
AI Overviews and Generative Search: Google and other search engines are using AI summaries more and more to give direct answers in the SERP.
Generative Engine Optimisation (GEO) is a separate field from traditional SEO that focuses on making content work better with AI-driven search engines like AI Overviews, ChatGPT Search, Bing Chat, and others.
AI Tools in Workflow: More and more SEO professionals are using AI tools to write content, do keyword research, and analyze the competition.
New AI features in Google Search Console make it easier to look at and understand performance data, such as trend views.
3) Quality and E-E-A-T are still very important
Google still rewards:
Knowledge, authority, and trustworthiness (E-E-A-T)
New ideas and real value for users
Content that is deep and meaningful (not thin or auto-generated)
This trend got stronger through 2025.
Changes to the user experience and the SERP
Searches with no clicks: Because answers show up right in the SERP, fewer people click on links that are lower down. This means that optimizing for AI answers and Featured Snippets will be more important than ever.
Visual and Video SEO: Image and video content are becoming more and more important for search visibility, especially indexed visuals on sites like Instagram.
What do GEO and AEO mean in SEO?
As search engines get better with AI, SEO is quickly moving beyond just ranking links. Two concepts that are increasingly becoming important are AEO and GEO.
AEO stands for Answer Engine Optimization
AEO aims at optimizing content such that search engines and AI tools can use your content to answer user queries directly.
In other words, AEO helps your content to become the answer, and not just a clickable link.
Where AEO works:
Google Featured Snippets
Google People Also Ask
Voice search: Alexa, Google Assistant
AI answers in search results
Example: If the question is “What is SEO?” and Google provides a direct answer box, that content is AEO-optimized.
How to Optimize for AEO:
Use clear questions and answers.
Keep explanations brief and to the point; use 40–60 words per explanation.
Include bullet points, frequently asked questions, and schema markup.
Use plain, human-friendly language.
GEO stands for Generative Engine Optimization.
GEO is focused on the optimization of content to be used, cited, or referenced by AI-powered search engines and generative tools.
Plainly stated: GEO helps AI systems trust and reuse your content when generating answers.
Where GEO Applies:
Google AI Overviews
ChatGPT, Bing AI, Gemini
Perplexity AI
Future search engines using AI
Example: If an AI summarizes “Best hair transplant clinics in Kolkata” and refers to a certain brand, then that brand is GEO-optimized.
How to Optimize for GEO:
Write authoritative content of an in-depth nature that shows experience and expertise (E-E-A-T).
Use authentic data, stats, and instances.
Build strong topical authority through content clusters.
Acquire brand mentions across trusted platforms.
