You can do that ?
Well, sort of… Google reserve some right to index whatever they can find online.
Often you’d want content to go offline if it’s old or otherwise irrelevant in the sense that it’s outdated.
The tool works on pages that are no longer active. That means that you need to remove the page in question, from your website for this to work. It has to be gone – literally.
This makes sense, but if the content still needs to be online, then you have the possibility to “noindex” it. This is a tag you put on links and a way for you to ask search machine bots not to index the page when they visit it. Whether they honour this request or not is entirely up to the search bot.
