A Webmaster asked on Twitter if let Google know about a URL shortener, so that the URL shortener does “hijack the page.”

I think he is worried about the URL shortener out-ranking the main URL. Here is his tweet:

John Mueller of Google responded saying “that shouldn’t be happening,” adding there is no reason to have to “register” the URL shortener.

John also said that if you are worried, you can “add a canonical to your pages to make it clearer.”

Here is John’s tweet:

I’ve never seen this question before, have you? I am personally not concerned with using URL shorteners.
