You can click on the "subscribe for updates" button to get the updates directly to your inbox.
Now, you can choose a page to not be indexed by search engines. All you have to do is add a Do not index property to your blog post/page.
If you don't want these pages to not appear in the navbar and footer too, then you can just leave the Placement property empty.
Now, it is possible for the title to be a language other than English. The slug will automatically be created from that title, even if the title is not an English title.
Now, you can choose whether a link is an internal link or an external link.
If it's an internal link, the link opens in the same tab. If it's an external link, it opens in a new tab.
Now, you can link to other blog posts/pages from within a blog post. They will open in the same blog itself, instead of opening the Notion page.
