Three years ago, ranking on Google was the goal. Now buyers ask ChatGPT, Perplexity, Claude, and Google's AI Overviews. The page that wins the citation wins the customer. The category has names already (Generative Engine Optimization, Answer Engine Optimization, LLM Optimization), but the tools and content are scattered across a few new startups and a handful of practitioner newsletters.
This is the curation we wish existed. Tools brands are paying for. Newsletters that publish original research, not recycled takes. Communities where practitioners trade what is working this week. Updated quarterly as the category settles.
LLM-powered search is no longer an experiment. ChatGPT crossed 200 million weekly active users. Google's AI Mode rolled out broadly in the US. Perplexity crossed 100 million monthly users and started running ads. These are buying channels now, not edge cases. The brands that don't show up in AI answers are simply invisible to a growing share of their market.
The mechanics are different from traditional SEO in a few specific ways. LLMs favor sources with clear entity definitions, structured content that answers specific questions, and third-party citations that establish credibility. A well-optimized traditional web page with a strong backlink profile can still miss AI citations entirely if it buries the direct answer the LLM needs. That's why practitioners here are building structured content, writing direct Q&A sections, and mapping their brand claims to the specific queries LLMs are being asked in their category.
The tools section below covers both the monitoring layer (tracking where and how your brand appears in AI answers) and the optimization layer (tools that help you structure content and build citations). The newsletters section covers the practitioners publishing original research on what's actually working, not just what makes sense in theory.
