What part of a URL can you delete?
What you can remove from a URL. Generally, if there's a question mark or a pound sign in a URL, you can remove everything after it and still have a working link. It's really that simple. Just note that sometimes removing stuff will change things on the page you're loading.
What is URL removal?
The URL removal tool is a feature of Google Search Console. You can use it when you don't want a certain page to appear in search results. The tool doesn't remove your URL from the Google Index but can temporarily hide it from users.
