+#### Setting author url
+
+Starting from August 6, 2021 [Google recommends](https://developers.google.com/search/updates) to set the `author.url` property. This property helps Google to disambiguate the correct author of the article.

+You can set it the same way as the other author properties. For example, you can put it in an `author` object, in the site's `_config.yml`, e.g.:

+    url: https://example.com/
