Currently, if project has multiple versions, when you search for articles in Google, it sometimes finds article from old versions. However, we need it to find articles from the newest version. For this, a project should have the canonical URL tag. Please add the ability to set canonical URLs in SEO section of the editor. The latest version of the docs should be canonical by default. Example and more details can be found here: https://docs.readthedocs.io/en/stable/guides/canonical.html
