Every week, a new "AI search revolution" makes headlines. But behind the buzz, the real shifts are quieter and measurable.
At Presenc AI, we've analyzed real interaction data from AI assistants and AI-powered search engines. Here's what's actually changing in 2025.
How Search Has Changed
Search moved from keyword-based ranking to AI-generated synthesis. We went from "ten blue links" to "zero-click answers." From SEO to GEO (Generative Experience Optimization).
But here's what most people misunderstand: AI search is not replacing Google. Information retrieval is being reimagined across multiple platforms (ChatGPT, Gemini, Perplexity, Copilot, and others), and the brands that only optimized for Google are discovering they're invisible everywhere else.
5 Real Trends for 2025
Trend 1: AI Search Is Becoming Conversational, Not Transactional
Query intent is evolving from keywords to conversations. People don't just search anymore. They ask, then refine, then ask again. They build context across multiple turns, treating AI assistants as collaborative thinking partners rather than lookup tools.
In our analysis of AI chat sessions across ChatGPT and Perplexity, average follow-up depth doubled year-over-year. Users now ask 3-5 follow-up questions before considering a search session complete. That changes what "ranking" means.
Implication: Brands must design content that survives multi-turn AI reasoning, not just one-shot keyword ranking. Your content needs to answer not just the initial question, but the inevitable follow-ups: "How does this compare?" "What are the trade-offs?" "Is this right for my specific use case?"
Trend 2: Sources Are Shrinking, Context Is Deepening
AI models now use curated retrieval datasets and trusted sources rather than broad web crawling. Unlike Google's index of trillions of pages, LLMs rely on high-authority, structured, and citation-rich data: Wikipedia, academic papers, verified knowledge bases, and authoritative industry publications.
The retrieval layer in modern AI search (RAG - Retrieval-Augmented Generation) doesn't just pull random web pages. It fetches semantically relevant chunks from pre-selected, trusted corpora. If your brand isn't part of these curated ecosystems, you're invisible, no matter how good your SEO is.
Implication: Visibility now depends on being part of these curated ecosystems, not just indexed websites. Focus on getting your brand into Wikipedia, Crunchbase, industry directories, and authoritative publications that AI models trust.
Trend 3: Personalization Is Quietly Taking Over
AI search assistants are building context memory and personal preference layers. ChatGPT remembers your past conversations. Perplexity adapts to your reading level and interests. Gemini integrates with your Google account to understand your professional context.
This means no two users see the same AI response. If you ask ChatGPT "What's the best project management tool?" today, and your colleague asks the same question tomorrow, you'll get different answers because the AI has learned about your team size, your technical expertise, and your workflow preferences.
Implication: GEO (Generative Experience Optimization) must include personalization testing: understanding how your brand appears across multiple user personas, contexts, and conversation histories. Traditional A/B testing won't cut it anymore.
Trend 4: Multimodal Search Is the New Default
AI search now integrates text + images + voice + code + documents in one seamless flow. Perplexity can analyze images you upload while answering your text questions. Gemini can read PDFs while generating summaries. ChatGPT can interpret charts, debug code, and write responses based on visual input.
Multimodal input is now the baseline expectation, not a differentiating feature. Users expect AI assistants to understand whatever they throw at it, in whatever format. The old categories of "image search," "text search," and "voice search" are dissolving.
Implication: Brands need to optimize for multimodal retrievability. That means structured images with proper alt-text that AI can parse, video transcripts, and code snippets with documentation. A product video with no transcript is invisible to RAG. Caption it.
Trend 5: AI Mentions Are the New Ranking
The new metric isn't position #1 on Google, but presence in AI-generated answers. In our analysis of brand queries across ChatGPT, Gemini, and Perplexity, AI assistants mentioned top brands 60–80% less frequently than their Google SERP rank would predict.
Think about it: if you rank #1 on Google for "project management software," you get the click. But if ChatGPT recommends three competitors and doesn't mention you at all, you get nothing, even if your website is technically indexed and retrievable.
This is creating a new visibility gap. Brands that dominate SEO are discovering they're invisible in AI. And there's no dashboard to track it until now.
Implication: Measuring "AI mention share" is the new visibility KPI. You need to know: How often does ChatGPT mention your brand? In what context? Compared to which competitors? For which types of queries?
Technical Insight: How AI Search Actually Works
AI search doesn't rank links. It retrieves chunks of meaning. Here's the technical pipeline:
- RAG (Retrieval-Augmented Generation): Combines trained knowledge with real-time retrieval
- Embedding-based semantic retrieval: Matches meaning, not keywords
- Context window reasoning: Processes 100K+ tokens of context to generate answers
- Reinforcement tuning: Models are tuned to prioritize factual accuracy and trusted sources
In plain terms: AI search doesn't find your content. It decides if your brand deserves to be part of the answer.
What This Means for Your Brand
Search isn't dying. But it has changed. Already in 2025, AI search isn't just retrieving content. It's filtering which brands appear in the answer at all.
The old playbook was simple: rank on Google, get traffic. The new one is harder: become part of the knowledge ecosystem that AI models actually draw from, and earn your way into their recommendations.
This requires a fundamentally different approach:
- Being mentioned in 100 AI answers is more valuable than 1,000 website visits that bounce. Think presence, not traffic.
- Create structured, factual, citation-worthy content that AI models will trust enough to reference
- Become the default answer for your problem domain across all AI platforms, not just Google
- Track how often, and in what context, AI assistants mention your brand. You can't improve what you can't see.
The Bottom Line
AI search is already directing discovery for a measurable share of B2B queries. Brands that aren't tracking their presence in AI-generated answers are missing a growing portion of their addressable pipeline.
