# Brand name differs across og:site_name, JSON-LD and title

`geo/entity-name-mismatch` · severity **info** · category AI search · detected by `void geo` and `void audit`

## Why it matters

Consistent entity naming helps search engines and LLMs merge mentions into one entity (Bing: consistent entities; Google site names).

## How to fix it

Define the name once (lib/site.ts) and use it for og:site_name, Organization/WebSite name, the title template and the llms.txt H1.
