 The `useSeoMeta` and `useServerSeoMeta` composables let you define your site's SEO meta tags as a flat object with full TypeScript support.
 
 This helps you avoid typos and common mistakes, such as using `name` instead of `property`.
 
-In most instances, the meta does not need to be reactive as robots will only scan the initial load. So we recommend using `useServerSeoMeta` as a performance-focused utility that will not do anything (or return a `head` object) on the client.
