Welcome to the Q&A Forum

I am trying to resolve a number of 4XX (Client Error) issues noted in my campaign report, but I have no idea where they are originating. All I get is the broken link, the status code, the page authority and the number of linking root domains. How do I identify where the erroring link originates? Is it coming from within my website, or from an external website? I have gone through my site in great detail looking for these links, but can't find any evidence of them. I also use a broken link detection plugin and it reports no problems whatsoever. Is there a way I can drill down into these 404 links and get more detail about where they are coming from?
