+Reactions to a website
+---------------------
+
+If the target of the reaction is a website, the reaction MUST be a `kind 17` event and MUST include an `r` tag with the website's URL.
+
+```jsonc
+{
+  "kind": 17,
+  "content": "⭐",
+  "tags": [
+    ["r", "https://example.com/"]
+  ],
+  // other fields...
+}
+```
+
+URLs SHOULD be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6), so that reactions to the same website are not omitted from queries.
+A fragment MAY be attached to the URL, to react to a section of the page.
+It should be noted that a URL with a fragment is not considered to be the same URL as the original.
