Meta Tags and SEO

[copy pasted from route module doc]

By default, meta descriptors will render a [<meta> tag][meta-element] in most cases. The two exceptions are:

• { title } renders a <title> tag
• { "script:ld+json" } renders a <script type="application/ld+json"> tag, and its value should be a serializable object that is stringified and injected into the tag.

export function meta() {
  return [
    {
      "script:ld+json": {
        "@context": "https://schema.org",
        "@type": "Organization",
        name: "React Router",
        url: "https://reactrouter.com",
      },
    },
  ];
}

A meta descriptor can also render a [<link> tag][link-element] by setting the tagName property to "link". This is useful for <link> tags associated with SEO like canonical URLs. For asset links like stylesheets and favicons, you should use the [links export][links] instead.

export function meta() {
  return [
    {
      tagName: "link",
      rel: "canonical",
      href: "https://reactrouter.com",
    },
  ];
}
