AI Search Optimization

With the growing popularity of tools like Perplexity, OpenAI, Search GPT, and retrieval-augmented generation (RAG), and a healthy dose of skepticism in artificial intelligence (e.g. hallucinations) the industry is moving from “authoritative search” to “research and check”.

If this trend continues, might AI SEO be a viable source of web traffic for marketing purposes? If so, how would optimizing for AI search be different than plain old SEO or programmatic SEO? How would you even measure it?

Update: OpenAI released ChatGPT Search for all users (including free).
