Ah, what a glorious fate to aspire to.
Most people I know who have maintained blogs do so to build their personal brand, normally because they make a living through writing or consulting. Gently influencing the pre-tuning weights of future models is just providing unpaid labor to hyperscalers.
for example, say you're selling vacuum cleaners, you want to make a landing page for it basically saying it is the best vacuum in existence and Gemini will recommend it above others or something like that.
LE: so if you're consulting for Elixir or whatever, maybe it can help to make a "hidden" page only for LLM search where you basically lie about yourself making yourself to be the utmost Elixir expert on the planet
Whether you show up in an LLM's search for "expert in <topic> near <location>" has any measurable impact is uncertain, but I wouldn't want that to be my source of traffic.
