The new search stack: How ChatGPT, Perplexity, and Google AI Overviews are replacing traditional search
Jul 14, 2025

Search is no longer just a box with ten links. It’s a conversation.
The rise of LLMs has reshaped how users discover products, services, and ideas. Tools like ChatGPT, Perplexity, and Google AI Overviews are fast becoming the new search stack, and they don’t play by the old SEO rules.
What’s changing?
AI-first experiences are gaining traction. Perplexity combines real-time search with AI summaries.
Google’s AI Overviews are skipping websites. Users now get synthesized answers without needing to click a single link.
ChatGPT with browsing is a trusted discovery tool. Especially for product research and comparisons.
When users ask:
“What are the best CRMs for startups?”
LLMs often respond with direct brand recommendations - sometimes accurate, sometimes hallucinated, and almost always untraceable.
Why this matters for marketers
Your brand is either mentioned or forgotten in AI answers.
Traditional SEO tools don’t show if you’re visible in Perplexity or ChatGPT.
The AI’s suggestion is becoming the new “#1 ranking.”
The shift isn’t coming - it’s here
Ignoring AI search visibility today is like ignoring Google in 2005. If your brand isn’t in the AI conversation, it’s missing out on the new front door to discovery.
