LLM search optimization means shaping public facts so a large language model can retrieve and repeat them. The model does not have a special doorway you pay to enter. It reads what the rest of the web already made easy to read.
What to publish
A page a person can check. Markup on your own domain. A public file that is not your theme. The same name in all three. That is the list.
What not to publish
A wall of hidden synonyms. A fake encyclopedia item. A press release every morning that repeats the same question so a vendor can show a chart. Frequency without identity is just noise with a calendar.
If you want the longer split between lists of links and generated answers, read SEO versus AI visibility.
Read why this exists. Check a name in the registry. Or start with a free check. Gold is $297 a year for a fuller identity. Paying does not itself verify the website.
