In 2025, AEO (Answer Engine Optimization) officially stopped being something niche, now it’s the new standard for search results optimization for businesses. Artificial intelligence no longer just helps search for information, it forms, aggregates and presents it to users as ready answers. Now getting even to Google TOP-1 doesn’t guarantee that users will visit your site rather than stop at AI suggestions.
While some marketers are still debating whether to adapt content for ChatGPT, Perplexity, Gemini, Claude.ai, Grok or Google AI Overview, leading SEO agencies in Europe are already actively implementing AEO in their strategies. They test new formats, structures, schemas and intents so that client sites appear not just in the top, but in LLM model responses themselves.
We’ve prepared a list of 10 leading companies that are already helping real businesses occupy places in AI results and intercept next-generation traffic.

Answer Engine Optimization is not “just another SEO trend”. It’s a new level of competition where pages are not just ranked, but become answers to user questions. In 2025, companies that first integrate AEO into their marketing strategy gain competitive advantage: AI search systems begin to form new sources of traffic, leads and sales.
Companies optimize pages for ChatGPT, Perplexity, Claude, Grok, as well as for future LLM-based platforms (Large Language Models). This is not only about technical SEO, but about AI SEO, optimization for AI responses and building AI visibility.
Top AEO agencies in Europe are already working proactively: creating content that gets into AI snippets, launching AEO strategies for clients and getting referral traffic from AI assistants.
If you still don’t analyze whether ChatGPT mentions you, whether your site is in AI Overview, whether it’s adapted for Perplexity, then be sure that competitors are already there. And they’re taking traffic from the future while you remain in the past.
