## Setting Default SEO Properties
You can set default SEO properties that will appear on every page without needing to add them individually. Common meta tags like `theme-color`, `manifest`, and `base` can be present on every page. If you configure the Svelte SEO in your `+layout.svelte`, these properties will stay fixed for every page. They can be changed on a per-page basis if necessary. For more information on using layouts and routing with SvelteKit, please refer to the official documentation at https://kit.svelte.dev/docs/routing#layout.
