        Wrapping Up

        Sofia’s scene for AEO, GEO, and LLMO work shows how a city like this can quietly build momentum in tech shifts. These companies, scattered around Bulgaria’s capital, handle the nuts and bolts of making sure content pops up in AI answers or generative searches, without much fanfare. It’s interesting to see them mixing old-school SEO tricks with newer tweaks for language models, especially as more folks turn to chatbots for quick info instead of scrolling through pages.

        Looking ahead, places like Sofia might keep drawing talent for this stuff, given the lower costs and solid skills here. If you’re running a business, paying attention to these approaches could mean staying visible in a world where search isn’t just about rankings anymore. It’s a reminder that tech hubs don’t always have to be in the usual spots – sometimes they’re in spots you least expect.
