something that's been kind of on my mind, Exa Labs + Perplexity have been the biggest AI native search engines that I've seen and used, but how do they figure out what sources to use to show the user?<p>found out this was called GEO (Generative Engine Optimization) and there's agencies that help you get your content to the top of AI search engines.<p>But how does this stuff even work? And what is the market for saas tools in GEO?<p>Interested to see how this market turns out but i'd love to know if anyone has seen some cool tools that people are building in that space.
