Find broken Links

Hello,

I’m in the process of optimizing my website SEO and during crawling I was shown a few incorrect links, e.g. https://www.frage-uns.definanzierung/

I know that there is a missing / between .de and finanzierung/ in the URL line. This is caused when I forward a link in Blocs to the URL without www e.g. https://frage-uns.de/finanzierung/ or https://frage-uns.de/finanzierung/#email-serie.

In the code I could search for the url https://frage-uns.de (without www) to find exactly these links. How do I do this in Blocs?

I would be happy to get a tip from you.

Best, Alex
