Changing URL in WordPress Block Editor (Gutenberg)
Changing Permalink In the Sidebar
If you edit a post or a page in the new Block Editor of WordPress, just click on the Post/ Page tab in the right sidebar, and you will be able to see a Permalink option where you can change URL slug.
Now if you click on the Permalink section, it will show an input that mainly allows you to edit the slug for your post/page. Also, make sure that you click on the Update button right after changing your permalink in order to apply the changes that you made right away.
If you are using the Squirrly SEO Live Assistant to optimize your article, make sure you include the keyword in the post/page URL.
