For the last few months I have been compiling every single bit of information I could find about the "New" SEO for LLM Search Engines like ChatGPT or Perplexity (also called GEO, LEO, LLMO, LLM SEO or AIO) to understand how they work, how to make the most out of them and how to position websites so that they can be found at all. It's being not an easy task as the available information is still very scarce, but I think I already have enough to put it all together in a practical guide.
Traditional SEO is not dead (yet), but it will be by 2027 and ignoring this now, could cause that no-one finds your site via organic searches or LLM searches any more very soon. This means that your web traffic will uniquely come from people who is accessing your site directly, or through links.
And the numbers don't lie:
📊 80% of consumers now rely on AI-generated content for 40% of their searches.
📉 25% reduction in organic web traffic due to zero-click searches. And it's going down quickly.
⚡ 1,200% growth in generative AI traffic in just 8 months.
🎯 90% of ChatGPT citations come from pages ranking 21+ (NOT your precious top 5 rankings!). Here's the brutal truth: While some are still optimizing for Google's Page 1, ChatGPT is mining pages 3, 5, and 10 for answers that millions trust daily. The shift is massive:
→ ChatGPT processes 1+ billion messages daily → Google's market share dropped below 90% for the first time since 2015 → Semrush predicts LLM traffic will COMPLETELY overtake traditional search by 2027 Traditional SEO is NOT prepared for this. The mechanics between generative AI and classic search are fundamentally different.
But here's the opportunity: Early adopters are seeing 35% increases in featured snippets and 27% more brand citations by implementing LLM optimization strategies.
I've compiled everything into a practical implementation guide + presentation covering:
✅ Semantic hub restructuring
✅ LLM-liftable content blocks
✅ Citation optimization frameworks
✅ The llms.txt standard implementation
✅ Measurement strategies for the new landscape
